Regulation of LYRM1 Gene Expression by Free Fatty Acids, Adipokines, and Rosiglitazone in 3T3-L1 Adipocytes

Abstract EN

LYR motif containing 1 (LYRM1) is a novel gene that is abundantly expressed in the adipose tissue of obese subjects and is involved in insulin resistance.

In this study, free fatty acids (FFAs) and tumor necrosis factor-α (TNF-α) are shown to upregulate LYRM1 mRNA expression in 3T3-L1 adipocytes.

Conversely, resistin and rosiglitazone exert an inhibitory effect on LYRM1 mRNA expression.

These results suggest that the expression of LYRM1 mRNA is affected by a variety of factors that are related to insulin sensitivity.

LYRM1 may be an important mediator in the development of obesity-related insulin resistance.
