Time-resolved expression profiling of the nuclear receptor superfamily in human adipogenesis.

ABSTRACT:

Background

The differentiation of fibroblast-like pre-adipocytes to lipid-loaded adipocytes is regulated by a network of transcription factors, the most prominent one being the nuclear receptor peroxisome proliferator-activated receptor (PPAR) γ. However, many of the other 47 members of the nuclear receptor superfamily have an impact on adipogenesis, which in human cells has not been investigated in detail.

Methodology/principal findings

We analyzed by quantitative PCR all human nuclear receptors at multiple time points during differentiation of SGBS pre-adipocytes. The earliest effect was the down-regulation of the genes RARG, PPARD, REV-ERBA, REV-ERBB, VDR and GR followed by the up-regulation of PPARG, LXRA and AR. These observations are supported with data from 3T3-L1 mou
