Loss of miR-133a alleviates the inhibitory effect of MyoD on brown adipogenesis. (a) ORO staining of brown adipocytes differentiated from miR-133a−/− BAT SVF cells transduced with control or MyoDOE adenovirus. (b and c) Immunostaining of BODIPY (red) in control (b) and MyoDOE (c) miR-133a−/− brown adipocytes. (d) Ratios of BODIPY signal in GFP+ cells in control and MyoDOE miR-133a−/− brown adipocytes. Five different areas analyzed in each experiment. (e) Fold changes of GFP+ BODIPY+ cells in WT and miR-133a−/− brown adipocytes after MyoD overexpression (f) qPCR analysis of miR-133a and miR-133b. (g and h) Fold changes of myogenic markers (g) and adipogenic markers (h) in WT and miR-133a−/− brown adipocytes after MyoD overexpression. Error bars represent mean with SD of three independent biological replicates.⁎P < 0.05 (Student's t-test).
