PIK3CA and neoplasm: We selected two additional tumor models, T11‐UV and T11‐Apobec, that displayed a high expression of Tgfb1 (both tumor models) and Tgfb2 (T11‐UV), high expression of Vimentin (Vim) and fibrotic marker (Pik3ca), and low expression of Cd36 and apoptosis regulator Bcl2 (Figure S7).
