Special Issue Information

Dear Colleagues,

Gene regulation, a finely tuned process, governs the activation or repression of genes, ensuring a dynamic response to internal and external cues. Within the context of endocrine physiology, this regulation is particularly crucial, dictating the synthesis and secretion of hormones that exert systemic effects on diverse tissues and organs. The dysregulation of gene expression in the endocrine system can lead to a spectrum of diseases, ranging from subtle imbalances to overt pathological states.

Endocrine diseases, sporadic and inherited or heritable, encompass a broad spectrum of conditions, including diabetes mellitus, thyroid disorders, adrenal dysfunction, neuroendocrine tumors, and disorders of the reproductive system. In each case, the perturbation of gene regulation emerges as a critical player, influencing the synthesis, release, and responsiveness of hormones. The advent of advanced genomic technologies has empowered researchers to dissect the genetic basis of these diseases, paving the way for targeted therapeutic approaches and precision medicine.

The integration of molecular genetics and endocrinology has unveiled a rich tapestry of mechanisms through which gene regulation contributes to the development and progression of endocrine disorders. From mutations in transcription factors that modulate hormone synthesis to alterations in the regulatory regions of hormone-encoding genes, the genetic landscape of endocrine diseases is becoming increasingly better understood at a molecular level. This Special Issue seeks to unravel the intricate interplay between gene regulation and endocrine diseases, offering insights into the molecular underpinnings that shape the pathophysiology of disorders within the endocrine system.

This study presents a comprehensive analysis of mitochondrial DNA (mtDNA) variations in dogs diagnosed with primary and recurrent tumours, employing Oxford Nanopore Technologies (ONT) for sequencing. Our investigation focused on mtDNA extracted from blood and tumour tissues of three dogs, aiming to pinpoint polymorphisms, mutations, and heteroplasmy levels that could influence mitochondrial function in cancer pathogenesis. Notably, we observed the presence of mutations in the D-loop region, especially in the VNTR region, which may be crucial for mitochondrial replication, transcription, and genome stability, suggesting its potential role in cancer progression. The study is pioneering in its use of long-read sequencing to explore the mutational landscape of mtDNA in canine tumours, revealing that while the overall mutational load did not differ between primary and recurrent tumours, specific changes in m.16168A/G, m.16188G/A, and m.16298A/G are linked with tumour tissues. Interestingly, the heteroplasmy outside the D-loop region was not specific to tumour tissues and did not provoke any malignant damage in protein-coding sequences, which in turn may be a tolerant effect of the reactive oxygen species (ROS) cellular stress mechanism.

Heat stress results in significant economic losses to the poultry industry. Genetics plays an important role in chickens adapting to the warm environment. Physiological parameters such as hematochemical parameters change in response to heat stress in chickens. To explore the genetics of heat stress resilience in chickens, a genome-wide association study (GWAS) was conducted using Hy-Line Brown layer chicks subjected to either high ambient temperature or combined high temperature and Newcastle disease virus infection. Hematochemical parameters were measured during three treatment phases: acute heat stress, chronic heat stress, and chronic heat stress combined with NDV infection. Significant changes in blood parameters were recorded for 11 parameters (sodium (Na+, potassium (K+), ionized calcium (iCa2+), glucose (Glu), pH, carbon dioxide partial pressure (PCO2), oxygen partial pressure (PO2), total carbon dioxide (TCO2), bicarbonate (HCO3), base excess (BE), and oxygen saturation (sO2)) across the three treatments. The GWAS revealed 39 significant SNPs (p < 0.05) for seven parameters, located on Gallus gallus chromosomes (GGA) 1, 3, 4, 6, 11, and 12. The significant genomic regions were further investigated to examine if the genes within the regions were associated with the corresponding traits under heat stress. A candidate gene list including genes in the identified genomic regions that were also differentially expressed in chicken tissues under heat stress was generated. Understanding the correlation between genetic variants and resilience to heat stress is an important step towards improving heat tolerance in poultry. Full article

Prostate cancer (PCa) remains a critical global health challenge, with high mortality rates and significant heterogeneity, particularly in advanced stages. While early-stage PCa is often manageable with conventional treatments, metastatic PCa is notoriously resistant, highlighting an urgent need for precise biomarkers and innovative therapeutic strategies. This review focuses on the dualistic roles of sirtuins, a family of NAD+-dependent histone deacetylases, dissecting their unique contributions to tumor suppression or progression in PCa depending on the cellular context. It reveals their multifaceted impact on hallmark cancer processes, including sustaining proliferative signaling, evading growth suppressors, activating invasion and metastasis, resisting cell death, inducing angiogenesis, and enabling replicative immortality. SIRT1, for example, fosters chemoresistance and castration-resistant prostate cancer through metabolic reprogramming, immune modulation, androgen receptor signaling, and enhanced DNA repair. SIRT3 and SIRT4 suppress oncogenic pathways by regulating cancer metabolism, while SIRT2 and SIRT6 influence tumor aggressiveness and androgen receptor sensitivity, with SIRT6 promoting metastatic potential. Notably, SIRT5 oscillates between oncogenic and tumor-suppressive roles by regulating key metabolic enzymes; whereas, SIRT7 drives PCa proliferation and metabolic stress adaptation through its chromatin and nucleolar regulatory functions. Furthermore, we provide a comprehensive summary of the roles of individual sirtuins, highlighting their potential as biomarkers in PCa and exploring their therapeutic implications. By examining each of these specific mechanisms through which sirtuins impact PCa, this review underscores the potential of sirtuin modulation to address gaps in managing advanced PCa. Understanding sirtuins’ regulatory effects could redefine therapeutic approaches, promoting precision strategies that enhance treatment efficacy and improve outcomes for patients with aggressive disease.

Primary hyperparathyroidism represents the third most prevalent endocrine disease in the general population, consisting of an excessive secretion of parathyroid hormone from one or, more frequently, more of the parathyroid glands, leading to a dysregulation of calcium homeostasis. Schematically, its development occurs primarily by pathophysiological events with genetic mutation, at the germline and/or somatic level, that favor the neoplastic transformation of parathyroid cells and promote their aberrant proliferation, and mutations determining the shift in the PTH “set-point”, thus interfering with the normal pathways of PTH secretion and leading to a “resetting” of Ca2+-dependent PTH secretion or to a secretion of PTH insensitive to changes in extracellular Ca2+ levels. Familial syndromic and non-syndromic forms of primary hyperparathyroidism are responsible for approximately 2–5% of primary hyperparathyroidism cases and most of them are inherited forms. The history of the genetic/molecular studies of parathyroid tumorigenesis associated with multiple endocrine neoplasia type 1 syndrome (MEN1) represents an interesting model to understand genetic–epigenetic–molecular aspects underlying the pathophysiology of primary hyperparathyroidism, both in relation to syndromic and non-syndromic forms. This minireview aims to take a quick and simplified look at the MEN1-associated parathyroid tumorigenesis, focusing on the molecular underlying mechanisms. Clinical, epidemiological, and observational studies, as well as specific guidelines, molecular genetics studies, and reviews, have been considered. Only studies submitted to PubMed in the English language were included, without time constraints. Full article

Medication-related osteonecrosis of the jaw (MRONJ) is a rare side effect of antiresorptive drugs that significantly hinders the quality of life of affected patients. The disease develops in the presence of a combination of factors. Important pathogenetic factors include inflammation, inhibition of bone remodeling, or genetic predisposition. Since the first description of this rare side effect in 2003, a growing body of data has suggested a possible role for genetic factors in the disease. Several genes have been suggested to play an important role in the pathogenesis of MRONJ such as SIRT1, VEGFA, and CYP2C8. With the development of molecular biology, newer methods such as miRNA and gene expression studies have been introduced in MRONJ, in addition to methods that can examine the base sequence of the DNA. Describing the complex genetic background of MRONJ can help further understand its pathophysiology as well as identify new therapeutic targets to better manage this adverse drug reaction.
