Figure Lengend Snippet: Knockdown of KLF15 and FoxO3a diminished protective effects of HMPA. Myotubes were transfected with GR, FoxO3a and NT siRNA as described in the Materials and Methods section, followed by the analysis of (A) GR, (B) KLF15 and (C) FoxO3a mRNA expression. The results are expressed as means ± SEM ( n = 4 per group). * p <0.05, ** p <0.01, *** p <0.001 indicates the significant difference between indicated groups. (D, E) Ubiquitin ligases Atrogin-1 and MuRF-1 expression in NT, GR/KLF15 and FoxO3a-siRNA transfected myotubes. Transfected myotubes were treated with HMPA for 1 h as pretreatment followed by Dex for 24 h. The results are expressed as means ± SEM ( n = 4 per group). * p <0.05, ** p <0.01, *** p <0.001 indicates the significant difference between indicated groups. siRNA, small interfering non-targeting RNA; GR, Glucocorticoid receptor; NT, non-targeting.
Article Snippet: Myotubes were transfected with the GR siRNA (Thermo Fischer Scientific), FoxO3a siRNA (Silencer ® Select siRNA FoxO3; ID - s80658) or non-targeting (NT) siRNA (Thermo Fischer Scientific) using the transfection reagent lipofectamine RNAiMAX (Thermo Fisher Scientific).
