High miR-93-5p CAF-derived exosomes stimulate the nuclear accumulation of TGFβ by downregulating FOXA1 and reducing its promoter-binding interaction with TGFβ, consequently enhancing the proliferation and shielding of CRC SW480 cells from radiation-induced apoptosis (Chen X. et al., 2020). Here, TGFB1 is linked to colorectal carcinoma.
