AKT1 and Familial prostate cancer: Overall, our data from CRC, cervical and prostate cancer cell lines lead us to conclude that glutamine depletion or inhibition of Akt/mTORC1 signalling induces a switch in the balance of exosome secretion towards vesicles from recycling endosomal compartments, increasing exosome levels of Rab11a, as well as Cav‐1, by several fold.
