Figure Lengend Snippet: Fig. 4. miR-199b-3p regulate the expression of mTOR (A) Quantitative analysis of mTOR in fibroblasts using qRT-PCR. (B) Quantitative analysis of mTOR in fibroblasts using western blot and the statistics. The originals gels can be seen in the supplementary figure S5. (C) Predicted miR-199b-3p target sequence of the mTOR 3’UTR using miRBase. (D) Quantification of miR-199b-3p and mRNA using qRT-PCR, the WT represents the mixture of the equal amount total RNA from the two healthy fibroblasts. Relative expression levels were normalized with GAPDH. (E). Luciferase reporter assay. (F) Quantitative analysis of mTOR in HEK293T cells at 48 h post-treatment with miR-199b-3p mimics (low panel) and the statistics (up panel). The originals gels can be seen in the supplementary figure S5. (G) Western bolt analysis of p-AKT, AKT, p-p70S6K, p70S6K in HEK293T cells at 48 h post-treatment with miR-199b-3p mimics,β-actin served as a control of total protein. (H) Quantitative analysis of mTOR in HEK293T cells at 48 h post-treatment with the inhibitor specific to miR- 199b-3p (low panel) and the statistics (up panel). (I) Western bolt analysis of p-AKT, AKT, p-p70S6K, p70S6K in HEK293T cells at 48 h post-treatment with the inhibitor specific to miR-199b-3p, β-actin served as a control of total protein. The originals gels can be seen in the supplementary figure S5.
