Also, in breast cancer samples from The Cancer Genome Atlas (TCGA), p-mTOR expression was also correlated with p-AKT, p-p70S6K, and a mTOR signature (r = 0.21–0.45) that was derived from expression levels of seven phosphoproteins in the pathway (Supplemental Table 7). Here, RPS6KB1 is linked to breast carcinoma.
