TREM-1, TREM-2, DAP12, HMGB1, RAGE, TLR-4 and TLR-2 mRNA expression studies using qPCR in the biopsy samples of study subjects. A: Gene Expression study in omentum biopsy samples. B: Gene Expression study in subcutaneous biopsy samples. C: Gene Expression study in liver biopsy samples. Results were expressed as fold change (relative to GAPDH) in obese non-diabetics and obese diabetics compared to non-obese subjects. The mRNA expression of these target genes levels in biopsy samples were compared between non-obese, obese non-diabetics and obese diabetics using One-way ANOVA for continuous variables. This study is an extended work to our previous published articles on TREM-1 and TREM-2 gene expressions in non-obese and obese populations [14]. Data were shown as mean ± SD (N=5 non-obese; 24 obese non-diabetics; 22 obese diabetics); *P<0.05, **P<0.01, ***P<0.001, and ****P<0.0001.
