Abstract
The pathogenesis of cancer is intricately associated with a multitude of factors, and its precise mechanisms continue to be a central focus of rigorous scientific inquiry. Adrenomedullin (ADM), initially characterized as a potent vasodilator, has subsequently been recognized for its diverse biological functions, including roles in angiogenesis, osteogenesis, and immune modulation. Recent studies have shown that ADM, secreted by tumor cells, also plays an important role in regulating immune escape and angiogenesis in the tumor microenvironment, promoting tumor cell proliferation, resisting apoptosis, adapting to anoxic environments, and participating in the process of chemotherapy resistance. Consequently, ADM is implicated in the pathophysiology of various cancers. This review summarizes the essential functions and potential mechanisms of ADM in the occurrence and progression in cancer, and presents the associated therapeutic challenges.
