Tumor necrosis factor-alpha and interleukin-1beta increases CTRP1 expression in adipose tissue

FEBS Lett. 2006 Jul 10;580(16):3953-60. doi: 10.1016/j.febslet.2006.06.034. Epub 2006 Jun 21.

Abstract

CTRP1, a member of the CTRP superfamily, consists of an N-terminal signal peptide sequence followed by a variable region, a collagen repeat domain, and a C-terminal globular domain. CTRP1 is expressed at high levels in adipose tissues of LPS-stimulated Sprague-Dawley rats. The LPS-induced increase in CTRP1 gene expression was found to be mediated by TNF-alpha and IL-1beta. Also, a high level of expression of CTRP1 mRNA was observed in adipose tissues of Zucker diabetic fatty (fa/fa) rats, compared to Sprague-Dawley rats in the absence of LPS stimulation. These findings indicate that CTRP1 expression may be associated with a low-grade chronic inflammation status in adipose tissues.
