Background/Objectives: Glioblastoma (GBM) is the most lethal primary brain malignancy in adults, with a median overall survival of approximately 15 months. Temozolomide (TMZ) resistance develops in virtually all patients, and no second-line regimen has improved outcomes over the past two decades. The DNA methyltransferase inhibitor decitabine (DAC) has attracted interest as a chemosensitizer, but whether it directly reverses the TMZ-resistance transcriptome or operates through distinct, complementary mechanisms has not been tested at multi-omics resolution. Methods: We performed an integrative six-layer multi-omics analysis across five public GEO datasets (bulk RNA-seq, EPIC 850K methylation, and 21,676 single cells) re-purposed from studies conducted for unrelated aims, formally tested DAC-mediated reversal of the TMZ-resistance transcriptome across 11,707 genes, mapped pharmacogenomic targets with DGIdb v5, and built an exploratory, hypothesis-generating 11-gene prognostic model internally validated in TCGA-GBM (n = 166) and externally tested in the independent CPTAC-GBM cohort (n = 96). Results: DAC reprogrammed transcription across 1114–1882 differentially expressed genes per cohort and reactivated 146 direct epigenetic targets, identifying INPP5D/SHIP1 as the top-ranked direct epigenetic-reactivation target. Genome-wide reversal analysis across 11,707 co-detected genes showed a negligible effect (Spearman ρ = 0.073), but single-cell analysis revealed significant per-cell attenuation of MES-like and stem-like programs (Δ = −0.071 and −0.135, respectively; both p < 0.001). The 11-gene risk model achieved a Harrell’s C-index of 0.706 (apparent); after correcting for the two-stage gene selection with a full-pipeline bootstrap, the optimism-corrected C-index was 0.63, and external validation in an independent cohort (CPTAC-GBM, n = 96) showed only near-chance discrimination (C-index 0.55), indicating that the signature does not generalize and is exploratory. Pharmacogenomic mapping yielded 734 unique therapeutic agents (230 FDA-approved) across 69 druggable targets after excluding AR. Most of these agents are not GBM-directed, so this catalog-level mapping is hypothesis-generating rather than a set of therapeutic recommendations. Conclusions: DAC does not broadly reverse the TMZ-resistant transcriptome but acts through three complementary mechanisms: epigenetic reactivation of INPP5D/SHIP1, cancer-testis-antigen and type I interferon induction, and per-cell attenuation of mesenchymal–stem-like transcriptional intensity, supporting hypotheses for rationally designed DAC-based combination therapy in TMZ-resistant GBM.

This exploratory study evaluated whether a polygenic risk score (PRS) derived from a European genome-wide association study is transferable to a Japanese cohort, for both susceptibility to and severity of adult idiopathic hydrocele testis. Surgically confirmed hydrocele cases were compared with two independently ascertained control groups: prostate cancer patients with intraoperatively confirmed absence of hydrocele fluid (Control 1), and urolithiasis patients without malignancy (Stone Control). Multivariable logistic regression evaluated disease occurrence; multiple linear regression restricted to hydrocele cases evaluated the association between PRS and fluid volume. A higher PRS was associated with increased susceptibility to hydrocele when cases were compared with Stone Controls (strictest threshold: odds ratio 1.98, 95% CI 1.01–3.88, p = 0.048; AUC 0.733), though this was not observed using Control 1. Among cases, PRS showed a consistent inverse association with fluid volume across all three thresholds tested (standardized β = −0.54, p = 0.010 at ≥10 mL). Given the modest sample size and limited statistical power, these findings should be regarded as preliminary and hypothesis-generating. They nonetheless suggest that genetic susceptibility to hydrocele and its severity may show different associations with polygenic risk, a pattern requiring confirmation in larger, independent, ideally East Asian-derived cohorts.

The increasing detection of small, non-palpable testicular lesions has challenged the traditional paradigm that every solid intratesticular mass should be managed by radical orchiectomy. Many incidental lesions, particularly in infertile men and in patients with negative tumour markers, are benign or non-neoplastic, making overtreatment a clinically relevant concern. In this setting, ultrasound has become central to a more conservative and individualised diagnostic strategy. By combining high-resolution grey-scale imaging with Doppler, microvascular imaging, CEUS and elastography, multiparametric ultrasound provides complementary information on lesion morphology, vascularity, stiffness and interval change. When integrated with clinical presentation, tumour markers, fertility status, syndromic background and patient history, these features can help characterise lesions and estimate the likelihood of malignancy in the appropriate clinical context. Although imaging cannot replace histology, it can refine pre-test probability, support active surveillance in selected low-risk lesions, guide testis-sparing surgery, and improve assessment of the operated testis. This review examines the role of multiparametric ultrasound in characterisation of focal testicular lesions across different clinical settings, including incidentalomas, acute scrotal pain, trauma, bilateral disease, heterogeneous parenchyma, genetic and endocrine syndromes, and the postoperative testis. A structured, context-sensitive imaging approach may help reduce unnecessary orchiectomy while preserving timely detection of malignant, persistent, recurrent or metachronous disease. Full article

Breast cancer (BC) is a heterogeneous disease influenced by genetic and regulatory mechanisms. Despite this, X-linked non-coding variants remain underexplored, particularly in admixed Latin American populations. Therefore, this study aimed to characterize the non-coding variant rs5945619 at Xp11.22 in Ecuadorian mestizo women with BC and to assess its potential regulatory effects on nearby genes through in silico cis-eQTL analysis. A prospective observational case series was conducted in 21 Ecuadorian mestizo women with histologically confirmed BC. Tumor DNA was extracted and analyzed using the Illumina TruSight Cancer Sequencing Panel. The rs5945619 variant was identified from sequencing data and compared with reference allele frequencies from dbSNP, ALFA, and the 1000 Genomes Project. Regulatory potential was assessed using RegulomeDB v2.2, and tissue-specific cis-eQTL associations were explored using GTEx. All 21 patients carried the genetic variant rs5945619 in a heterozygous state. The mean age at diagnosis was 54.5 ± 12.2 years, and invasive breast carcinoma of no special type was the predominant histological subtype. The T-allele frequency in the study cohort was 0.50, whereas Latin American reference populations showed higher frequencies ranging from 0.69 to 0.83. RegulomeDB assigned rs5945619 a rank of 1f and a functional score of 0.22, supporting its regulatory potential. GTEx analysis identified tissue-specific cis-eQTL signals, including LINC01496 upregulation in testis, NUDT11 and LINC01496 downregulation in prostate, and modest GSPT2 downregulation in mammary tissue. This study provides the first characterization of rs5945619 in Ecuadorian mestizo women with BC and suggests its role as a potential X-linked regulatory variant, requiring further validation. Although universal heterozygosity was observed, the small sample size, tumor-only design, and absence of a healthy control cohort prevent any causal, risk-factor, or tumor-driven selection inference. The in silico evidence supports a tissue-dependent regulatory model involving LINC01496 and NUDT11, mainly in prostate/testis, and a modest GSPT2 signal in mammary tissue. Therefore, breast cancer-specific eQTL analyses, functional validation, and larger ancestry-informed case–control studies are required to determine the biological and clinical relevance of this locus.

Background/Objectives: Korea has experienced rapid and heterogeneous shifts in cancer epidemiology since 1999. We aimed to characterize divergent incidence trajectories across the 24 major cancer types, quantify sex-specific burdens, and project case counts through 2030. Methods: Annual incidence data—including new case counts and age-standardized incidence rates (ASIRs) per 100,000 (2020 Korean standard population) stratified by sex—were extracted from the KCCR via the Korean Statistical Information Service (KOSIS) for 1999–2023. Annual percent change (APC) was estimated by log-linear regression with 95% confidence intervals (CIs). Holt–Winters damped exponential smoothing generated 2024–2030 projections with 95% prediction intervals (PIs). Changes in case ascertainment and coding over the study period were considered in interpretation. Results: Total incidence increased from 101,854 (1999) to 288,613 cases (2023), a 183.4% increase. Overall ASIR rose from 402.7 to 522.9 per 100,000. Of the 24 cancer types, 15 showed statistically significant increasing ASIR trends, 6 showed significant decreasing trends, and 3 showed no significant change. The highest-APC cancers were thyroid (+7.56%), prostate (+6.98%), testis (+5.39%), breast (+5.03%), and corpus uteri (+5.03%; all p < 0.001). The largest significant declines occurred in cervix uteri (−3.81%), larynx (−3.18%), liver (−2.90%), and stomach (−2.20%; all p < 0.001). Female ASIR increased from 294.7 to 488.9 per 100,000 (+65.9%); male ASIR increased from 573.3 to 587.0 per 100,000 (+2.4%). Total cancer incidence is projected to reach 307,091 (95% PI: 281,200–332,983) in 2026 and 330,213 (95% PI: 290,663–369,763) by 2030, with the steepest projected relative growth for prostate (+48.9%), kidney (+33.7%), and breast (+31.3%) cancers. Conclusions: Korean cancer epidemiology is undergoing a pronounced transition from infection-related toward metabolic, hormonal, and aging-related malignancies, with a marked and widening sex-specific divergence. Cancer-type-resolved projections through 2030 provide an evidence base for strategic capacity planning in Korean oncology. Full article

Objectives: Obesity and the associated metabolic dysfunction influence fertility performance at molecular levels and ABC transporters are considered as potential molecular factors affecting fertility both in the testis and sperm; therefore, we aimed to examine the effect of a short-term diet-induced obesity on testicular and spermatic ABC transporters in a rat model focusing on the expressions of P-glycoprotein (P-gp, Abcb1) and breast cancer resistance protein (BCRP, Abcg2). The testicular androgen state involving aromatase enzyme (Cyp19a1), androgen receptor (Ar), and testosterone levels were also evaluated. Methods: Obesity was induced in male Sprague Dawley rats by feeding a high-fat, high-sugar diet (HFHSD) for 10 weeks, and metabolic status was evaluated using a glucose tolerance test. The weight and size of reproductive organs were measured, and Abcb1a/1b, Abcg2, Cyp19a1, and Ar expression in testes or sperm was determined by RT-PCR and Western blotting. At the same time, testosterone levels were measured by ELISA. Results: HFHSD successfully induced higher weight gain with glucose intolerance and reduced reproductive organ size. In obese rats, testicular Abcb1a and Abcb1b mRNA and P-gp protein expression were significantly higher, whereas testicular Abcg2 mRNA levels decreased. Spermatic Abcb1a, Abcb1b and Abcg2 mRNA expression also reduced in obesity. Neither testicular testosterone concentration nor Cyp19a1 and Ar mRNA expression levels changed after the 10-week obesogenic diet compared with controls. Conclusions: Overall, our study revealed infertility-related ABC transporter changes in obese male rats, suggesting that these alterations may predispose obese males to fertility impairments, even before the obesity-induced androgen dysregulation.

Background/Introduction: Prostate cancer (PCa) is the most commonly diagnosed malignancy among men and remains a major cause of cancer-related mortality worldwide. We aimed to evaluate whether radiomic features extracted from normal endocrine organs, combined with clinical variables, could predict clinical progression in patients with PSMA-negative prostate cancer. Materials and Methods: In this retrospective study, 101 men with biochemically recurrent prostate cancer and negative [¹⁸F]DCFPyL PET/CT scans were included. Radiomic features were extracted from the adrenal glands, thyroid, the hypothalamus–pituitary complex, and testes. Post-imaging variables were excluded to prevent temporal data leakage. Models were developed using a stratified train/test split framework with preprocessing and feature selection performed exclusively within the training subset prior to evaluation on the held-out test set. Performance was evaluated using AUC, accuracy, sensitivity, specificity, and Brier score, while bootstrap confidence intervals and DeLong analysis were used for statistical assessment. Results: Multimodal fusion models integrating CT radiomics, PET radiomics, and clinical variables demonstrated the strongest predictive performance. The highest-performing model combined TESTIS_CT and TESTIS_PET radiomics with clinical variables, achieving an AUC of 0.758 (95% CI: 0.653–0.849). Clinical-only models remained highly competitive, with the best configuration achieving an AUC of 0.727 (95% CI: 0.618–0.833). PET + clinical and CT + clinical models achieved AUC values of up to 0.733 and 0.729, respectively, while imaging-only models demonstrated substantially lower discrimination. Although endocrine organ radiomics numerically improved predictive performance and specificity, DeLong analysis demonstrated no statistically significant improvement beyond clinical variables alone. Discussion: These findings suggest that endocrine organ radiomics may provide complementary system-level imaging biomarkers reflecting tumor–host interactions in PSMA-negative prostate cancer. However, their incremental clinical value remains modest. Conclusions: Endocrine organ radiomics combined with clinical variables demonstrated promising predictive performance in PSMA-negative prostate cancer, particularly in multimodal fusion models. Nevertheless, the added value beyond clinical variables alone was not statistically significant and requires validation in larger independent cohorts. Full article

Background/Objectives: Liposarcoma represents a heterogeneous group of mesenchymal malignancies with distinct molecular profiles and clinical behaviors. While localized disease is managed with surgical resection, advanced or metastatic liposarcoma poses a significant therapeutic challenge due to limited response to traditional cytotoxic chemotherapy. This review summarizes current evidence-based systemic therapies and highlights recent advances in subtype-driven treatment strategies. Methods: We review key clinical trials supporting the use of anthracycline regimens, trabectedin, eribulin, and nuclear export inhibition with selinexor, as well as emerging targeted approaches directed at MDM2 and CDK4 amplification. In addition, we discuss the evolving role of immunotherapy, including checkpoint inhibitors and engineered T-cell receptor therapies targeting cancer–testis antigens. Results: Integrating molecular biology with therapeutic development, we emphasize the importance of histologic and genomic classification in guiding treatment selection and clinical trial design. Conclusion: Continued progress in biomarker-driven strategies and rational combination therapies is expected to further refine personalized treatment approaches and improve outcomes for patients with advanced liposarcoma.

Background/Objectives: Testicular cancer accounts for approximately 1% of all male malignancies, with an incidence ranging from 1 to 10 per 100,000 men and it predominantly affects young individuals, with nearly 60% of cases diagnosed between 15 and 35 years of age. In recent decades, the incidence of testicular cancer has markedly increased, paralleling a global rise in male infertility rates. Although chemotherapy is known to adversely affect fertility, the extent to which the tumor itself and its different histological subtypes impact semen quality remains incompletely understood. The aim of this study was to evaluate semen parameters in men diagnosed with testicular cancer prior to oncological treatment and to assess the possible association between tumor histology and semen quality. Methods: This retrospective study included data from 284 men diagnosed with testicular cancer who underwent semen cryopreservation prior to surgery, chemotherapy, or radiotherapy. Data were collected between January 2016 and June 2022 at the Maternal and Child Department of the University of Naples Federico II. Histopathological classification was available for 278 patients and revealed the following distribution: 59% (165/278) classic seminoma, 14.7% (41/278) seminomatous mixed germ cell tumors, 13.3% (37/278) non-seminomatous mixed germ cell tumors, and 12.6% (35/278) non-seminomatous germ cell tumors. Results: No significant association was observed between tumor histology and abnormal semen parameters. According to World Health Organization (WHO) reference values, semen parameters in patients with testicular cancer were predominantly distributed between the 5th and 25th percentiles. Microscopic semen analysis revealed significantly lower sperm concentration, total motility, and normal morphology in cancer patients (p < 0.001; p < 0.001; and p < 0.002, respectively). Logistic regression analysis showed a significant association between age and testicular cancer risk (p < 0.001), with a negative coefficient indicating that the likelihood of developing the disease decreases with increasing age. Additionally, patients with seminoma were significantly older than those with non-seminomatous tumors: on average, 4.07 years older than those with pure non-seminoma (p = 0.007) and 5.60 years older than those with mixed non-seminoma (p < 0.001). No statistically significant age differences were observed among non-seminomatous subtypes. Conclusions: These findings underscore the importance of systematic semen evaluation in young men diagnosed with testicular cancer and highlight the critical role of fertility preservation strategies in the comprehensive management of these patients.

Cryptorchidism is the most prevalent congenital anomaly of the male genitourinary tract, with an incidence of approximately 1 to 9 percent in full-term male infants, decreasing with age due to spontaneous descent. It encompasses testes that fail to descend into the scrotum, which may be intra-abdominal, inguinal, or ectopic, and can be associated with syndromic, genetic, or environmental factors. The descent process occurs in two phases: intra-abdominal, driven by gubernacular development and androgen-independent mechanisms, and inguinoscrotal, regulated by hormonal and mechanical factors including androgens and the gubernaculum. Clinically, cryptorchidism manifests as absent or hypoplastic scrotal testes, often with inguinal fullness. Palpation and physical examination are primary diagnostic tools, with imaging such as ultrasound or MRI reserved for specific cases. Surgical exploration remains the definitive diagnostic modality, especially for nonpalpable testes. Early referral, ideally before 12 months of age, is essential for timely orchidopexy, which aims to position the testes within the scrotum to reduce risks of torsion, trauma, subfertility, and malignancy. Hormonal therapy shows limited efficacy and is generally not recommended as a primary treatment modality. Long-term outcomes indicate that early orchidopexy improves spermatogenic potential and fertility. Men with a history of cryptorchidism exhibit elevated risks of subfertility and testicular germ cell tumors, with the risk being higher if surgical correction is delayed or if testes remain intra-abdominal. The increased malignancy risk persists even after orchidopexy, underscoring the importance of vigilant surveillance. Management strategies emphasize a multidisciplinary approach, combining surgical intervention with ongoing monitoring, to optimize functional and oncological outcomes. Early diagnosis, appropriate surgical treatment, and patient education are critical components in minimizing long-term complications associated with cryptorchidism. Full article

Testicular tumors are the most common neoplasms of the canine male reproductive tract, corresponding to approximately 25% of all tumors in intact males. A large percentage of cases are characterized by one of three main tumor types: seminomas, interstitial Leydig cell tumors, or Sertoli cell tumors. Clinical importance is primarily associated with endocrine activity rather than malignant behavior; orchiectomy is the treatment of choice for most canine testicular cancers. Endocrine activity, particularly estrogen secretion, may result in feminization syndrome and, in severe cases, bone marrow suppression. The diagnostic approach combines physical examination, ultrasonography with hormonal assessment using endocrine testing (testosterone, estradiol, and T:E ratio), and/or tissue level evidence of the estrogen effect (preputial cytology). Management is centered on orchiectomy; unilateral surgery may be considered when the contralateral testis is clinically and ultrasonographically normal and when preservation of reproductive capacity or working ability is still a priority. Dogs with hormonally active tumors benefit from postoperative hematologic and endocrine monitoring. Recent advances in immunohistochemistry (IHC), such as Ki-67 and inhibin-α markers, and imaging techniques are improving tumor characterization and individualized clinical decision making.

Background/Objectives: Oral squamous cell carcinoma (OSCC) commonly arises from oral potentially malignant disorders (OPMDs), yet reliable molecular biomarkers that predict malignant transformation remain scarce. Because epithelial carcinogenesis follows similar multistep trajectories across multiple organs, pan-cancer transcriptional analyses may reveal conserved pathways relevant to early oral tumorigenesis. This study aimed to identify shared transcriptional signatures across carcinomas and evaluate their applicability to precancerous-to-carcinoma progression. Methods: Bulk RNA-seq data from five carcinomas (lung, colon, breast, prostate, and head and neck squamous cell carcinoma, HNSCC) were obtained from TCGA to identify shared differentially expressed genes (DEGs) (|log₂FC| ≥ 2; FDR < 0.05). Functional enrichment, clustering, and gene–pathway network analyses characterized conserved biological processes. Independent GEO datasets containing premalignant and malignant samples, including OPMD and OSCC cohorts, were examined to assess early-stage relevance. Results: A conserved 45-gene signature was identified, enriched for transcriptional regulation, chromatin organization, and RNA polymerase II-mediated processes. Regulatory hubs, including ZIC5, MYBL2, ONECUT2, POU4F1, and PDX1, and strong upregulation of cancer-testis antigens (MAGEA3, MAGEA6, MAGEC2) were notable. Integration with premalignant datasets revealed 13 genes consistently dysregulated across early lesions, involving pathways such as cell differentiation, apoptosis, and lipid transport. Several genes remained altered from normal tissue through OPMD to OSCC, supporting their potential as stable biomarkers. Conclusions: This study identifies conserved transcriptional programs shared across epithelial cancers and detectable in OPMDs. These findings highlight promising biomarker and regulatory candidates for improving early detection and risk stratification of oral precancer, addressing a critical unmet need in OSCC prevention and clinical management.

Background/Objectives: Testicular germ cell tumors, particularly seminoma, represent the leading cause of cancer in men aged 15–40 years. The decision about adjuvant therapy relies on histological features with uncertain prognostic value. The Pituitary-Tumor-Transforming Gene 1 (PTTG1), which encodes the securin protein, is crucial in sister chromatid separation. Our previous in vitro studies demonstrated that PTTG1 nuclear expression promotes invasiveness, dedifferentiation, and neolymphangiogenesis in testicular seminoma. Methods: We conducted a hypothesis-generating retrospective observational study on 51 patients (aged 23–68) with testicular seminoma, with (43%) or without (57%) lymph node involvement, evaluating potential correlations between PTTG1 and currently known prognostic factors. Clinical and pathological data were collected, including lymph node involvement, recurrence, necrosis, rete testis invasion, vascular invasion, and adipose tissue invasion. An immunohistochemical scoring system assessing intranuclear PTTG1 expression was developed. Results: The PTTG1 score was related to lymph node metastasis and adipose tissue invasion. ROC curve analysis showed that the PTTG1 immunohistochemical score showed good discriminatory ability in identifying lymph node involvement (AUC = 0.939); the optimal cut-off was 4.0 (sensitivity 90.5%; specificity 57.1%), while the ROC curve for adipose tissue invasion was inadequate. Lymph node metastasis also correlated with necrosis; however, logistic regression confirmed that PTTG1 score was independently associated with nodal involvement (p = 0.002), regardless of tumor size and necrosis. Conclusions: Our findings suggest a correlation between PTTG1 expression and lymphadenopathy at diagnosis, independent of tumor size and T stage. It may reflect biological features associated with lymphatic dissemination and requires further investigation in larger prospective studies. Full article

Background: Paraneoplastic limbic encephalitis (PLE) with anti-Ma2 antibodies is a rare immune-mediated disorder associated with testicular cancer, particularly in young males. While neurological manifestations are well documented, hypothalamic–pituitary dysfunctions remain underreported. We present a case of anti-Ma2 PLE associated with testicular cancer together with a systematic review of PLE associated with testicular cancer, selectively restricted to anti-Ma2 positive cases and focusing on hypothalamic–endocrine involvement. Case presentation: We describe a 21-year-old male diagnosed with anti-Ma2 PLE and intratubular germ cell neoplasia of the right testis. He underwent orchifunicolectomy and immunosuppressive therapy with neurological improvement. Four years later, he developed new-onset temporal seizures, decreased libido, and a polyuria–polydipsia syndrome. Dynamic endocrine testing, including a water deprivation test and copeptin measurement, supported a diagnosis of partial central diabetes insipidus (CDI). Methods: A systematic literature review was performed in accordance with PRISMA guidelines. PubMed was searched using predefined keywords without time restriction. Studies reporting PLE associated with testicular tumors in humans with confirmed anti-Ma2 antibody positivity were included. Results: Eleven studies were included, reporting a total of 38 patients with anti-Ma2-associated PLE and testicular cancer. Hypothalamic or diencephalic involvement was described in 16 patients (42.0%), while endocrine manifestations were explicitly reported in four cases. Only two previous reports mentioned CDI, without detailed diagnostic evaluation. Conclusions: This study highlights the importance of recognizing hypothalamic-endocrine manifestations in PLE. In patients presenting with polydipsia and polyuria, CDI should be carefully differentiated from primary polydipsia using dynamic testing. Hypothalamic involvement may emerge years after tumor treatment, warranting long-term endocrine surveillance. Full article

Chromatin is a dynamic cellular structure basically constituted by nucleosomes, which consist of a DNA sequence wrapped around an octameric histones core. Histone synthesis and transport, nucleosome formation and proper chromatin assembly is an ordered and stepwise process guided by histone chaperones. Several families of histone chaperones have been identified and one of them is the nucleosome assembly protein (NAP) superfamily. Members of this family have been involved not only in chromatin constitution and regulation but also in several other cellular processes, such as nucleocytoplasmic shuttling, DNA replication, transcription and cell-cycle regulation. Testis specific protein Y-like 2 (TSPYL2) is a peculiar member of the NAP superfamily of histone chaperone. This protein has been initially isolated as a nuclear antigen in patients affected by discoid lupus erythematosus and as a TGF-β target. Its ability to bind histones has been demonstrated. In addition, TSPYL2 has been reported to regulate transcription, cell-cycle progression and the DNA-damage response, independently of its role in chromatin organization. In accordance with its multiple functions, defects in TSPYL2 have been associated with different diseases, mainly cancer and neurodevelopmental abnormalities. In this review we summarize and discuss the multiple cellular functions of TSPYL2, pointing out new and unexpected aspects like a sex-related activity and their relationship with different diseases.
