There is growing evidence that physical exercise is associated with epigenetic alterations in prostate tissue, although its consequences on the prostate are yet unknown. It is well recognized that epigenetic changes, including DNA methylation and histone modifications, interfere with important biological functions in malignancies, including tumor development, tissue invasion, and metastasis, and they also increase the likelihood of genetic abnormalities. Notably, exercise has been shown to have anticancer, DNA methylation, histone, microRNA, lncRNA, and apoptosis-inducing properties. Exercise capacity to alter biomarkers of DNA methylation, histone changes, miRNA, lncRNA, and apoptotic induction makes predictive diagnostics possible, enabling patient stratification and early identification of at-risk patients.

Prominent GRPs such as GRP78, GRP94/gp96, GRP75, and GRP170 play a great role in cancer cell survival and progression by promoting protein folding, immune evasion, and resistance to therapy. Within the tumor microenvironment, which is characterized by hypoxia, acidosis, and nutrient deprivation, GRPs can facilitate critical processes including proliferation, angiogenesis, metastasis, and apoptotic resistance. Moreover, beyond their intracellular roles, GRPs have been found to possess considerable immunogenic potential when expressed on the cell surface or secreted. As a result, these findings have led to the development of GRP-based cancer vaccines that can elicit robust adaptive immune responses by chaperoning tumor antigens to antigen-presenting cells. Current evidence suggests GRP75 (HSPA9/mortalin) is less immediately tractable than ER-resident GRPs (78/94/170) for vaccine design, primarily owing to its mitochondrial localization and poor antigen accessibility. However, nanoparticle-mediated delivery or CRISPR-engineered surface expression could reposition it as a future target, pending advances in intracellular antigen presentation pathways. Preclinical models have demonstrated that GRP-based immunotherapy can induce cytotoxic T lymphocyte responses and tumor regression. Additionally, repurposing GRP-targeted strategies from infectious, autoimmune, and neurodegenerative disease contexts may offer promising translational avenues in the field of cancer. Despite encouraging results, challenges such as tumor heterogeneity, immune suppression, and delivery optimization have still remained. Therefore, future research should aim to increase antigen specificity, optimize vaccine formulations, and explore combinatory regimens to overcome resistance mechanisms in cancer cells.
