ABSTRACT
Objective To observe serum secreted protein acidic and rich in cysteine (SPARC) levels in normal subjects,obese subjects,patients with type 2 diabetes mellitus (T2DM),and obese patients with T2DM,as well as the difference of SPARC expression in mesenteric adipose tissue of subjects with and without T2DM.Methods Serum SPARC level was measured with the ELISA.RT-PCR,Western blot,and immunofluorescence were used to examine SPARC mRNA and protein expressions in mesenteric adipose tissue.Results (1) SPARC levels were higher in obesity,T2DM,and T2DM with obesity groups compared with normal group [(1 191.6 ± 718.91,1 223.81 ± 645.96,1 538.01 ± 757.95 vs 851.07 ± 280.21) ng/L,P<0.05].(2) Pearson correlation analysis showed that SPARC level was positively correlated with homeostasis model assessment for insulin resistance index (r =0.205,P< 0.05).(3) The expression levels of SPARC mRNA and protein in mesenteric adipose tissue of T2DM patients were higher than those of control subjects (P < 0.05).Conclusion SPARC is closely related to the development of obesity,insulin resistance,and type 2 diabetes mellitus.
