Figure Lengend Snippet: Expression of the lipid metabolism regulator PPARβ and downstream effectors (CPT1b, FAS, and ACC2). mRNA levels in obese rats under hypoxic conditions, with hypoxic training, and with regulated miR-122 expression were determined using qRT-PCR. OE, obese rats with miR-122 overexpression and hypoxic training; IE, obese rats with miR-122 depletion and hypoxic training; CE, obese rats with hypoxic training only; H, obese sedentary rats without regulation of miR-122 expression. Data are presented as mean ± SD. *p < 0.05, **p < 0.01 vs rats in group H; # p < 0.05, ## p < 0.01 vs rats in group CE; & p < 0.05, && p < 0.01 vs rats in group OE (1-way analysis of variance).
Article Snippet: The protein samples were then transferred to a PVDF membrane (0.45-μm pore size) at a constant pressure of 100 V for 10 min, followed by blocked overnight in Tris-buffered saline with 0.1% Tween-20 (TBST), which contained 5% bovine serum albumin, and then probed overnight at 4 °C with primary antibodies against PPARβ (1:2000; GTX113250) and FAS (1:1000; GTX13550) (both from GeneTex, Irvine, CA, USA) and ACC2 (1:500; A03668-2) and CPT1b (1:500; PB9491) (both from Boster Bio, Pleasanton, CA, USA).
