Figure 4. mTOR signaling pathway was activated in the cystic cells, cystic RCC cells.
(A) Cystic RCC was stained by hematoxylin and eosin (H&E). (B) No FLCN expression was detected in cystic RCC, indicating deletion of the BHD gene. Phosphorylated mTOR (C) and phosphorylated S6 (D) staining was observed in the corresponding FLCN-deficient cells. Scale bar = 50 µm.
