Figure Lengend Snippet: High-fat diet (HFD)-induced obesity and impaired insulin sensitivity are attenuated in lncMGC KO mice (A) Representative images of wild type (WT) and lncMGC KO control (Con) and HFD-fed male and female mice after 20 weeks on the HFD. (B–D) Biweekly body weight gain, (C) endpoint body weight, (D) gWAT weight, (E) total fat mass, (n = 7–8 mice/group), and (F) adipocyte size (5/group), in male and female mice. (G–I) plasma insulin levels, (H) HOMA-IR, and (I) area under the curve (AUC) for GTT, in male and female mice. (J–L) IHC staining of F4/80 (macrophage inflammation marker) and CD31 (endothelial cell marker) in gWAT sections from WT and lncMGC KO male and female mice. Scale bars, 50 μm. Quantitative analysis of (K) F4/80 ( n = 5/group) and (L) CD31 ( n = 5/group) in male and female mice. (M) Gene expression of lncMGC (n = 4-7, lncMGC was not detected by qPCR in 4 samples in lncMGC KO HFD mice ), Chop , Vegfb , and Pparg in isolated stromal vascular fraction (SVF) from gWAT in male and female mice (n = 7–8/group). Statistical analyses were performed by two-way ANOVA with post-hoc Tukey test for multiple comparisons. Student’s t tests for comparisons between two groups. XY graphs show the mean (SD). The bar and whisker plot displays the distribution of the data. The whiskers extend from the minimum to the maximum values. Individual data points are overlaid as dots. Statistically significant p values are indicated in the bar graphs.
Article Snippet: For IHC, the following primary antibodies were used: anti-UCP-1 (1:100, ab10983, Abcam); anti-FIS-1 Rabbit polyclonal antibody (1:100, 10956-1-AP, Proteintech, USA); anti-SDHB (1:200, 10620-1-A, Proteintech, USA); ani-YBX1(1:500, LS- B12352 , LSBio, USA); and rabbit monoclonal antibody anti-CD31(1:50, 77699, cell signaling) and anti-F4/80 (1:100, 70076, cell signaling) and anti-CHOP (1:50, 15204-1-AP, Proteintech, USA).
