Ginsenoside Rg1 Inhibits STAT3 Expression by miR-15b-5p to Attenuate Lung Injury in Mice with Type 2 Diabetes Mellitus-Associated Pulmonary Tuberculosis

Figure 3

Rg1 inhibits STAT3 expression by upregulating miR-15b-5p. (a) The expression of miR-15b-5p was tested by qPCR in lung tissues of T2DM-associated PTB mice. (b) The interaction site of miR-15b-5p and STAT3 was predicted. (c, d) The 293T cells were treated with miR-15b-5p mimic. (c) The luciferase activity of STAT3 3′UTR was analyzed. (d) The expression of STAT3 was analyzed by qPCR. (e) The expression of STAT3 was detected by Western blot in 293T cells treated with Rg1 and miR-15b-5p inhibitor. Cont represents the PBS treatment group; Rg1 represents the Rg1 treatment group; Rg1 + miR-15b-5p inhibitor represents the treatment with Rg1 and miR-15b-5p inhibitor; WT represents the wild-type vectors; and MUT represents the mutated vectors; vs Cont group, vs Rg1 group.
