This review comprehensively explores how these epigenetic alterations modulate immune cell infiltration, antigen presentation, immune checkpoint expression, and tumor immunogenicity across cervical, ovarian, and endometrial cancers. We also delineate the impact of specific epigenetic enzymes, such as DNMTs, HDACs, BET and RNA methyltransferases, in shaping immune responses and discuss the therapeutic potential of targeting these regulators to sensitize tumors to immune checkpoint inhibitors, cancer vaccines, cytokine based treatments and adoptive T-cell therapies. Furthermore, we examine the integration of epigenetic agents such as DNMT and HDAC inhibitors with immunotherapies in preclinical and clinical settings, emphasizing their synergistic capacity to overcome immunoresistance.

Transdifferentiation of GBM stem-like cells (GSCs) into GSC-derived endothelial cells (GdECs) contributes to GBM neovascularization. To dissect the molecular mechanisms and the signaling pathways underlying GSC contribution to tumor vascularization, we identified a three miRNA signature able to discriminate GSCs from GdECs by regulating different signaling pathways. DUSP8 resulted as the common target of the miRNA signature identified and is negatively regulated by miR-1825. DUSP8 is emerging as a critical negative regulator MAPKs pathway and is involved in cell oxidative stress response and apoptosis, as well as, in several diseases, including cancer. In GBM patients, DUSP8 and miR-1825 expression are inversely correlated and DUSP8 down-regulation is significantly associated with higher microvascular density and poor overall survival. Exploring the impact of DUSP8 in GSC transdifferentiation, we demonstrated that DUSP8 down-regulation interferes with MAPK pathway and affects soluble factor release. In vitro DUSP8 modulation experiments showed that DUSP8 enforced expression impairs GdEC ability to form tube-like structures. Gene expression variations induced by DUSP8 modulation affect transcripts associated with EMT pathway, confirming that DUSP8 shutdown and, therefore, the activation of MAPK pathway, is mandatory to GSC transdifferentiation. In vivo experiments demonstrated that both DUSP8 enforced expression and silencing dramatically affect gliomagenesis.
