Abstract
The Transforming Growth Factor-β (TGF-β) mediates embryonic development, maintains cellular homeostasis, regulates immune function, and is involved in a wide range of other biological processes. TGF-β superfamily signaling pathways play an important role in cancer development and can promote or inhibit tumorigenesis. Type III TGF-β receptor (TGFBR3) is a co-receptor in the TGF-β signaling pathway, which often occurs with reduced or complete loss of expression in many cancer patients and can act as a tumor suppressor gene. The reduction or deletion of TGFBR3 is more pronounced compared to other elements in the TGF-β signaling pathway. In recent years, lung cancer is one of the major malignant tumors that endanger human health, and its prognosis is poor. Recent studies have reported that TGFBR3 expression decreases to varying degrees in different types of lung cancer, both at the tissue level and at the cellular level. The invasion, metastasis, angiogenesis, and apoptosis of lung cancer cells are closely related to the expression of TGFBR3, which strengthens the inhibitory function of TGFBR3 in the evolution of lung cancer. This article reviews the mechanism of TGFBR3 in lung cancer and the influencing factors associated with TGFBR3. Clarifying the physiological function of TGFBR3 and its molecular mechanism in lung cancer is conducive to the diagnosis and treatment of lung cancer.
Keywords: TGFBR3, lung cancer, expression deficiency, invasion, metastasis, proliferation, apoptosis.
