MTOR and hematocrit: The results showed that the phosphorylated AKT, mTOR, and its downstream target S6 expression levels were significantly upregulated in the TFCs of HT patient tissues compared with the healthy controls, whereas the total AKT, mTOR, and S6 expression levels in the TFCs were at the similar levels between the healthy controls and HT patients (Figures 7A–C).
