miR-26b-5p alters hADMSC adipogenic differentiation. (A) When hADMSCs were transfected with an miR-26b-5p mimic, significant increases in miR-26b-5p expression were observed relative to cells transfected with an miR-Ctrl construct, whereas this expression was significantly reduced in cells transfected with an miR-26b-5p inhibitor relative to corresponding controls. (B) Cells transfected with an miR-26b-5p mimic were evaluated via qPCR, revealing significant increases in the expression of C/EBP, PPARγ, and aP2, and significant decreases in the expression of TCF7L2 and β-catenin relative to cells transfected with the mimic control construct. (C) Cells transfected with an miR-26b-5p inhibitor were evaluated via qPCR, revealing significant increases in the expression of C/EBP, PPARγ, and aP2, and significant decreases in the expression of TCF7L2 and β-catenin relative to cells transfected with the inhibitor control construct. *P < 0.05. GAPDH: glyceraldehyde 3-phosphate dehydrogenase; hADMSC: human adipose-derived mesenchymal stem cell; PPARγ: peroxisome proliferator-activated receptor γ; qPCR: quantitative polymerase chain reaction.
