We investigated the expression of TIMP1, TIMP2, SPARC, VCAN, and CLEC3B genes, encoded matricellular proteins with pleiotropic functions, and glucose intolerance in obese male subjects with normal and impaired glucose tolerance. The purpose of this study was to examine the association between the gene expressions and glucose intolerance in obesity. The results indicate that obesity leads to significant increase of TIMP1, TIMP2, E2F1 and CLEC3B gene expressions in subcutaneous adipose tissue,

No significant changes were found in the expression of VCAN and SPARC genes in adipose tissue of obese subjects with normal glucose tolerance but increased in the group of obese subjects with glucose intolerance. At the same time, the E2F1 and CLEC3B gene expressions were decreased in adipose tissue of obese patients with glucose intolerance. Results of this study provide evidence that changes in the expression of genes encoded TIMP1, TIMP2, VCAN, SPARC, E2F1 and CLEC3B in subcutaneous adipose tissue of obese individuals associate with glucose intolerance. 47 Figure 4. The correlation between body mass index (BMI) and TIMP1 (a); TIMP2 (b); E2F1 (c) and CLEC3B (d) gene expressions in the obese men with normal glucose tolerance versus lean subjects.
