Special Issue Information

Dear Colleagues,

Over the last decade, our understanding of the tumor microenvironment (TME) has expanded remarkably, revealing a complex network of cancer cells, immune cells, stromal components, and signaling factors that collectively shape tumor progression and therapeutic outcomes. Despite significant progress, numerous aspects of how the TME contributes to immune evasion and treatment resistance remain to be fully clarified. Addressing these gaps is crucial in refining current immunotherapies and discovering novel interventions that can transform cancer care.

For this Special Issue, I invite you to submit an original research article or review exploring facets of the TME and its impact on cancer immunotherapy. We welcome expert contributions covering mechanistic insights into immune modulation, strategies for reshaping the TME, biomarker discovery, and innovative combination therapies. Your valuable work will help us unlock new frontiers in TME research and ultimately improve patient outcomes. I look forward to your contributions and the exciting discussions that they inspire.

Dr. Xin Lu
Guest Editor

Ovarian cancer remains the most lethal gynecological malignancy, largely due to its early dissemination and extensive peritoneal metastasis. The tumor microenvironment (TME), particularly tumor-associated macrophages, promotes this invasive phenotype; however, the precise molecular effectors linking immune-to-tumor signaling remain unclear. We identified FRY, a microtubule-binding protein previously uncharacterized in ovarian pathology, as a critical mediator of macrophage-driven invasion. We observed that conditioned medium from ovarian cancer-stimulated macrophages (OCM) robustly induced FRY expression in ovarian cancer cells. Clinically, elevated FRY levels correlate with advanced tumor stage and poor patient survival. Functionally, FRY knockdown significantly abrogated OCM-induced invasion without affecting cell viability, highlighting its specific role in motility. Mechanistically, FRY facilitates epithelial–mesenchymal transition (EMT) and acts as an essential downstream effector of the PI3K/AKT signaling cascade; notably, FRY was required for AKT1-driven invasive behaviors. Furthermore, we identified the transcription factor NFIX as a key regulator of FRY expression. Macrophage-derived signals upregulate NFIX, which directly regulates FRY transcription. Pharmacological inhibition of the CXCR1/2 axis with reparixin effectively blocked OCM-mediated induction of both NFIX and FRY, suggesting that chemokine signaling initiates this pro-invasive loop. Collectively, these findings suggest that FRY is a macrophage-driven mediator of invasion and underscore its potential relevance in ovarian cancer. Full article

Cancer remains a major global health challenge requiring the development of diagnostic and therapeutic strategies. Liquid biopsy is considered a promising minimally invasive tool for cancer screening, prognosis and treatment monitoring. Recent studies suggest that neutrophil extracellular traps (NETs) may also be potential liquid biopsy markers. NETs are web-like chromatin structures released by neutrophils in response to various stimuli to trap and neutralize pathogens. However, excessive or dysregulated NET formation has been implicated in tumor progression and metastasis. Elevated levels of NETs have been observed in patients with various types of cancer and correlate with disease stage and prognosis. The presence of NET markers such as citrullinated histone H3 (H3Cit), neutrophil elastase (NE) and myeloperoxidase (MPO) has been associated with higher tumor burden and poorer clinical outcomes. Several studies have shown a positive correlation between NET markers and circulating free DNA (cfDNA) levels, suggesting that NETs may increase the sensitivity of liquid biopsy in detecting and monitoring cancer progression. This review examines the role of NETs in the tumor microenvironment, their contribution to cancer progression and metastasis, and their potential use in liquid biopsy and cancer therapy. Full article
