Members of the transforming growth factor beta (TGF-β) superfamily are multifunctional cytokines that regulate several cellular processes, including cell cycle arrest, differentiation, morphogenesis, and apoptosis. TGF-β promotes extracellular matrix production and morphological change. Morphogenetic responses to TGF-β include cell migration and epithelial-mesenchymal transition (EMT), which are critical during embryogenesis, development of fibrotic diseases, and the spreading of advanced carcinomas. The purpose of this study was to clarify how TGF-β regulates the fate of retinal pigment epithelial (RPE) cells. TGF-β1 promoted cell cycle progression and phosphorylation of retinoblastoma protein (Rb) in ARPE-19 cells. TGF-β1 induced survivin expression, which in turn stabilized tubulin and Aurora B. RT-PCR and western blot analysis revealed that survivin expression increased in ARPE-19 cells following TGF-β1 treatment. When survivin was depleted, TGF-β1 induced cell cycle arrest and apoptosis and also reduced Rb phosphorylation. In conclusion, the present study shows that induction of EMT in human RPE cells upregulates survivin, leading to survivin-dependent inhibition of cell cycle arrest and apoptosis. Whether cells undergo EMT or apoptosis in response to TGF-β1 is dependent on their cell cycle state, and TGF-β1 regulates the cell cycle via survivin.
