Data obtained using CRISPR-Cas9 gene editing of RPTOR and RICTOR in combination with data obtained by 4E-BP1 siRNA rescue of the inhibitory effects of AZD8055 on the TGF-β1 collagen response provide strong support that our key observation regarding the critical role of the mTORC1/4E-BP1 signaling during fibrogenesis is generalizable to other key effector cells of the fibrotic response in the context of the skin (pHDFs), the liver (HSCs), and the stromal reaction in lung adenocarcinoma (CAFs). The gene discussed is EIF4EBP1; the disease is lung adenocarcinoma.
