Figure 1From: Integrative network analysis reveals different pathophysiological mechanisms of insulin resistance among Caucasians and African AmericansGenes showing strong differential expression in adipose tissue of African Americans (AA) compared to Caucasians (CA). A) Genome-wide expression microarray identified 2-fold higher expression of the CRYBB2, SF1, GSTT2B, and CLEA4A gene in AA subjects, while expression of DHRS4L1, MARCO (Macrophage receptor with collagenous structure), and USMG5 was lower; B) Technical validation by qRT-PCR confirmed lower expression of MARCO gene in adipose tissue of AAs compared to CAs. MARCO expression is shown after 36B4 normalization and ln transformation. In A and B the box represents the interquartile range, which contains 50% of the values. The whiskers are lines that extend the box to the highest and lowest values, excluding outliers. A line across the box indicates the median; and C)MARCO expression is positively correlated with BMI in 99 non-diabetic CA subjects.Back to article page
