Expression data from mouse perigonadal white adipose tissue - various mutant conditions [exon-level analysis]


ABSTRACT: Progerin-expressing mice (HGPS-like) demonstrated increased energy metabolism and lipodystrophy. Increased mitochondrial biogenesis was found in adipose tissue from HGPS-like mice, whereas lamin C-only mice had fewer mitochondria. Thus we analyse which molecular pathways mediated the changes in adipose tissue caused by lamin C and progerin expression and the roles of these pathways in energy metabolism and aging. 10 cDNAs samples were analysed. We compared the mean fold change of 2 to 4 biological replicates. We performed an unpaired Student’s t-test to compare intensities in the different biological replicates. Genes were considered significantly regulated when the fold change was ? 1.5, and the p-value was ?0.05.

Alternative RNA processing of LMNA pre-mRNA produces three main protein isoforms, that is, lamin A, progerin, and lamin C. De novo mutations that favor the expression of progerin over lamin A lead to Hutchinson-Gilford progeria syndrome (HGPS), providing support for the involvement of LMNA processing in pathological aging. Lamin C expression is mutually exclusive with the splicing of lamin A and progerin isoforms and occurs by alternative polyadenylation. Here, we investigate the function of lam  ...[more]
