Abstract
Activin A, a gonadal protein, not only stimulates the pituitary to secrete follicle-stimulating hormone (FSH) but also plays a crucial role in regulating various cell behaviors, such as cell proliferation, differentiation, apoptosis, migration, and invasion. Studies have shown an association between activin A expression and tumor progression, highlighting its dual role in cancer. Similar to transforming growth factor-beta (TGF-β), activin A can have both pro-tumor and anti-tumor effects, for instance, it inhibits the migration of lung adenocarcinoma cells, while promotes the migration of triple-negative breast cancer cells. Therefore, activin A exerts context-dependent effects on different tumor cells. This review explores the biological functions of activin A in tumor progression and treatment, focusing on its influence on tumor cell proliferation, apoptosis, and metastasis. The aim is to offer insights and potential directions for future clinical cancer treatments.
