Rapamycin Differentially Regulates mTORC1 and mTORC2 in Diabetic Rabbits Following I/R Injury
(A) Upper panel shows the representative immunoblots and lower panel shows densitometry analysis of the ratios of phosphorylation of S6 to total S6 (p-S6/S6; n = 6; ∗p < 0.0001 versus control, DM, DM + I/R + RAPA; αp<0.0001 versus I/R), phosphorylation of AKT to total AKT (p-AKT/AKT; n = 6; ∗p < 0.01 versus control and DM; αp<0.0001 versus control, DM and DM + I/R + RAPA), and total proteins to GAPDH (S6/GAPDH; n = 6; ∗p < 0.05 versus control, I/R and DM and AKT/GAPDH; n = 6; ∗p < 0.001 versus others).
(B) Real-time PCR analysis shows the levels of miR-302a (∗p < 0.05 versus control and DM; αp<0.001 versus others and βp<0.001 versus control and DM).
(C) Real-time PCR analysis shows the levels of PTEN mRNA (∗p < 0.05 versus control and DM; αp<0.001 versus others).
(D) Representative immunoblots (upper panel) and densitometry analysis (lower panel) of the expression of PTEN and GAPDH in hearts of control and diabetic rabbits before/after I/R and with/without RAPA treatment (n = 6; ∗p < 0.0001 versus others). Statistics: one-way ANOVA. Data are represented as mean ± SEM.
