The mRNA expression levels of adipokines in EAT between the two groups. (A): the result of agarose gel electrophoresis of PCR products in EAT. (B): the result of relative mRNA levels of chemerin, chemR23, adiponectin and TNF-α in EAT of the two groups (CAD group, n = 37; NCAD group, n = 16). ** indicates P < 0.01, CAD group vs. NCAD group. Abbreviations: a.u., arbitrary units.
