Expression data from wild-type and Zmpste24-/- mouse embryonic fibroblasts (MEFs) at an early passage (passage 3, P3)

ABSTRACT: Zmpste24 is a metalloproteinase processing prelamin A into mature lamin A, a nuclear structure protein. Zmpste24-/- mice which accumulate prelamin A in cells recapitulate accelerated aging phenotypes observed in human premature aging disorder, Hutchinson Gilford progeria sydrome (HGPS). Zmpste24-/- mouse embryonic fibroblasts (MEFs) exhibited genomic instabiliy and accelerated aging at cellular level, which is premature senescence. We performed microarray analysis on Zmpste24-/- MEFs, compared to wild-type littermates' MEFs, at an early passage (P3), which is a pre-symptom stage before cellular senescence occurs in the mutant MEFs, in order to examine gene expression profile and figure out the underneath mechanism triggering the premature aging process. Overall design: Early passage wild-type and Zmpste24-/- MEFs were collected for RNA extraction, the quality of RNAs were determinded by Electrophoresis Assay (2100 Bioanalyzer, Agilent) and RNA extractions were used for hybridization on Affymetrix microarrays.
