Mean BMI = 29.12; rs7903146 genotype [CC]). (One-way ANOVA followed by Tukey's multiple comparisons test.) (E) TCF7 protein levels in TCF7L2 KD DFAT abdominal APs (one-way ANOVA followed by Tukey's multiple comparisons test). shCN = scrambled control, sh897 = moderate and sh843 = high TCF7L2-KD DFAT abdominal APs. Actin was used as a loading control for western blots. qRT-PCR data were normalized to 18S rRNA levels. Histograms are means ± SEM. Data obtained from 3 independent experiments. ###P < 0.001, ##P < 0.01, #P < 0.05 (adjusted for multiple comparisons).

Highlighted are the top 30 differentially regulated genes. (E) Overrepresentation analyses of genes differentially regulated in sh843 and sh897 DFAT abdominal APs, vs. controls in gene ontology biological processes gene sets. P-value was adjusted using the FDR (Benjamini-Hochberg) procedure. Gene ratio represents the percentage of total DEGs in the given GO term.

Figure Lengend Snippet: Fig. 7. Schematic summarizing the role of TCF7L2 and impact of rs7903146 genotype on human AP biology. TCF7L2 has dose-dependent effects on adipo genesis with moderate and high-efficiency knockdown leading to enhanced and impaired adipogenesis respectively in vitro. In fractionated adipose tissue expression of TCF7L2 in APs correlates positively with donor BMI whilst the T2D risk variant (T) at rs7903146 is associated with reduced AP TCF7L2 expression. Based on these findings we speculate that lean homozygous T2D risk variant carriers would have the lowest AP TCF7L2 expression and conse quently impaired adipogenesis, larger adipocytes, increased adipo-IR and higher susceptibility to T2D compared with obese T2D risk variant carriers.
