Abstract
Tumor progression can be affected by various cellular components of tumor cells and/or by tumor microenvironmental factors. The tumor microenvironment comprises a variety of nonmalignant stromal cells and inflammatory cytokines, which are pivotal in tumor promotion and progression. The transforming growth factor‑β (TGF‑β) ligands (TGF‑β1, 2 and 3) are secreted inflammatory cytokines, which are known to be involved in various aspects of tumor development through two transmembrane serine‑threonine kinase receptors, TGFβR1 and TGFβR2. TGF‑β promotes or inhibits tumorigenesis depending on the concurrent gene mutations and tissue microenvironment present through the small mothers against decapentaplegic (Smad) and non‑Smad pathways. This review aims to provide a comprehensive overview of the role of the TGF‑β pathway in tumor initiation and progression.
