Molecular Mechanisms of Autophagy Regulation in Cancer

An essential cellular mechanism called autophagy breaks down and recycles damaged macromolecules and organelles to keep cells in a state of homeostasis. Autophagy dysregulation has been linked to several illnesses, including cancer. This abstract discusses the complex molecular pathways that control autophagy and its crucial function in the initiation and progression of cancer. A complex interplay of signaling pathways, such as mTOR, AMPK, and PI3K/AKT, which regulate autophagy-related gene expression and protein activity, is involved in the regulation of autophagy. The coordination of autophagosome formation, cargo recognition, and lysosomal breakdown is furthered by important autophagy-related proteins such Beclin-1, LC3, and p62. In cancer, autophagy serves a dual role in encouraging tumor survival in established tumors by supplying nutrients under stressful situations while also acting as a tumor suppressor in early stages by removing damaged components. This abstract explores the context-dependent roles of autophagy in various cancer types and explores prospective therapeutic approaches that focus on autophagy to treat cancer. A thorough comprehension of the complex molecular mechanisms governing autophagy regulation in cancer could open new possibilities for developing customized treatments and enhancing patient outcomes. To target this process for therapeutic purposes, researchers are aggressively investigating the role of autophagy in cancer. Some anticancer medications work by preventing autophagy in cancer cells, which increases their susceptibility to therapy. On the other hand, some scientists are investigating how to stimulate excessive autophagy to encourage the self-destruction of cancer cells.
