Abstract

Transforming growth factor‐beta (TGFβ) is a secreted cytokine, which intricately controls a plethora of physiological and pathological processes during development and carcinogenesis. TGFβ exerts antiproliferative effects and functions as a tumor suppressor during early stages of tumorigenesis, whereas at later stages it functions as a tumor promoter aiding in metastatic progression through an autocrine TGFβ loop. Intricate knowledge of TGFβ signaling and its regulation are still evolving. In this review, we make an attempt to showcase the associated enigma of TGFβ signaling in its dual functional role as tumor suppressor and metastatic promoter during early and late stages of carcinogenesis, respectively. © 2009 IUBMB IUBMB Life, 61(10): 929–939, 2009

Regeneration involves a number of cellular processes: revascularisation, invasion by haemopoietic cells, removal of necrotic tissue and finally reformation of the tissues. These processes have been extensively studied in vitro and are known to be affected by various growth factors. However, it has p

The majority of ocular melanomas occur in the uveal tract. Chemotherapy is generally ineffective and large tumours requiring enucleation have a greater than 50% mortality at 5 years. Monosomy for chromosome 3 is common in uveal melanoma and it is known that there is loss of responsiveness to transfo
