Autophagy in cancer associated fibroblasts promotes tumor cell survival Role of hypoxia, HIF1 induction and NFκB activation in the tumor stromal microenvironment

Recently, using a co-culture system, we demonstrated that MCF7 epithelial cancer cells induce oxidative stress in adjacent cancer-associated fibroblasts, resulting in the autophagic/lysosomal degradation of stromal caveolin-1 (Cav-1). However, the detailed signaling mechanism(s) underlying this proc...
