Figure 4: CTRP3 activated the AKT signaling pathway. (a–c) The protein expression of AKT and mTOR was detected by western blot analysis (). (d) Cell viability in HUVECs induced by high glucose (). (e) The mRNA expression of TNF-α in HUVECs exposed to high glucose (). Data are expressed as of five independent experiments. when compared to the matched control.
