(Submitter supplied) Mitochondria play an essential role in the ability of brown fat to generate heat, and the PGC-1 coactivators control several aspects of mitochondrial biogenesis. To investigate their specific roles in brown fat cells, we generated immortal preadipocyte lines from the brown adipose tissue of mice lacking PGC-1α. We could then efficiently knockdown PGC-1β expression by shRNA expression. Loss of PGC-1α did not alter brown fat differentiation but severely reduced the induction of thermogenic genes. more...

(Submitter supplied) To investigate the specific role of PGC-1 coactivators in brown fat cells, we generated immortal preadipocyte lines from the brown adipose tissue of mice lacking PGC-1alpha. We could then efficiently knockdown PGC-1beta expression by shRNA expression. Loss of PGC-1alpha did not alter brown fat differentiation but severly reduced the induction of thermogenic genes. In order to assess the specific requirement for PGC-1α in the global transcriptional response to cAMP, we used Affymetrix arrays to compare the sets of genes induced in response to a 4 hr dbcAMP treatment in differentiated wt and KO cells. more...

Analysis of PGC-1alpha null brown adipocytes treated with cAMP for 4 hours. PGC-1alpha is required for the thermogenic function of brown fat cells, and cAMP plays a role in thermogenesis. Results provide insight into the role of PGC-1alpha in the global transcriptional response to cAMP.

Analysis of brown fat cells lacking PGC-1alpha or both PGC-1alpha and PGC-1beta. PGC-1alpha is required for the thermogenic function of brown fat cells, and PGC-1beta is the closest homolog of PGC-1alpha. Results provide insight into the specific roles of PGC-1alpha and PGC-1beta in brown fat cells.
