Multiple tumor-related pathways

"Multiple tumor-related pathways" is a generic term describing the diverse array of molecular signaling pathways that can become aberrantly activated, inactivated, or otherwise altered in tumor cells. These pathways include, but are not limited to, the p53 pathway, cell cycle control pathways (such as those governed by Rb, CDK/Cyclins), mitogenic signaling cascades (RTK/RAS/PI3K), Wnt, Hippo, and apoptosis-regulating pathways. Functional or genetic alterations in these pathways contribute to cancer hallmarks such as uncontrolled proliferation, resistance to cell death, impaired DNA repair, and evasion of immune surveillance. While components within individual pathways are often therapeutic targets (e.g., EGFR, BRAF, PI3K), "multiple tumor-related pathways" as a term is too broad and does not identify a specific druggable target[1][3]. Because this is not an individual molecule, receptor, enzyme, transporter, or specific actionable entity, but rather a functional grouping used in genomics and systems biology to discuss commonalities across different cancer types, it cannot be directly mapped to a structured target entry[1][3][4].
