Apoptosis is a feature of TGF beta-induced cataract.

Background: Studies in our laboratory have shown that transforming growth factor beta (TGF beta) induces rodent lens epithelial cells to undergo aberrant growth and differentiation that reproduces morphological and molecular features of human anterior subcapsular cataract and posterior capsule opacification. In addition, features of apoptosis have been described in some forms of human cataract. In the present study we investigated apoptotic changes induced by TGF beta in our rodent models.
