Multiple pathways and epigenetic processes

The term Multiple pathways and epigenetic processes does not refer to a single molecular target but rather a broad set of biological mechanisms involved in the regulation of gene expression and cellular signaling. Epigenetic processes include chemical modifications to DNA or histones—such as methylation and acetylation—that alter chromatin structure and gene accessibility without changing the underlying DNA sequence (NIH, 2023). These processes, along with various signaling pathways like the PI3K/Akt or MAPK pathways, are frequently dysregulated in complex diseases, particularly cancer, where they drive uncontrolled proliferation and survival (PubMed, PMID: 30077564). Therapeutic strategies targeting these areas often utilize multi-target inhibitors, such as histone deacetylase (HDAC) inhibitors or DNA methyltransferase (DNMT) inhibitors, to reprogram the cellular environment and restore normal gene function (PubChem). Because this entry lacks a specific molecular structure or single gene product, it is classified as a descriptive term for therapeutic strategies rather than a discrete target. Due to the broad nature of these processes, drugs acting on them often face challenges related to systemic toxicity and lack of specificity.
