TGFB1 and ovarian carcinoma: Starvation‐induced differentiation of fibroblasts in myofibroblasts, as marked by the de novo synthesis of ASMA and increased expression of stress fibers, strictly depended on induction of autophagy.139 Similarly, one can hypothesize that the differentiation of stromal fibroblasts into myofibroblasts induced by TGF‐β1 and other cytokines secreted by ovarian cancer cells66 occurs through the upregulation of autophagy.
