lncRNA-ES3/miR-34c-5p/BMF axis is involved in regulating high-glucose-induced calcification/senescence of VSMCs

Figure 4. BMF was the target of miR-34c-5p. (A) Schematic representation of the miR-34c-5p putative target sites in BMF 3’UTR and alignment of miR-34c-5p with WT and Mut BMF 3’UTR showing pairing. The mutated nucleotides were underlined. (B and C) HA-VSMCs were transfected with miRNA NC, miR-34c-5p mimics, and miR-34c-5p inhibitors, and harvested for the examination of BMF mRNA and protein. (D) The WT-BMF 3’UTR and Mut-BMF 3’UTR were co-transfected with miR-34c-5p mimics or control oligos into HA-VSMCs. Forty-eight hours after transfection, luciferase activities were measured. (E and F) qRT-PCR and Western blot analysis showed the expression level of BMF in HA-VSMCs cultured with NG, OC, and HG. (G) HA-VSMCs were transfected with shRNAs NC and shlncRNA-ES3-2, and the protein level of BMF was detected by Western blot. The data are expressed as mean ± SD, n=3, *p<0.05, **p<0.005, ***p<0.0005. NG: normal glucose; OC: osmolarity control; HG: high glucose; NC: negative control.
