Expression data from PKM1 or PKM2 expressing mouse embryonic fibroblasts.

ABSTRACT: We profiled global gene expression for two separate lines of mouse embryonic fibroblasts and find that deletion of PKM2 and expression of PKM1 does not alter global gene expression profiles. We used microarrays to futher characterize the effects of PKM1 expression compared to PKM2 expression on global gene expression in mouse embryonic fibroblasts. Primary mouse embryonic fibroblast cells were used for RNA extraction and hybridization on Affymetrix microarrays. Intensity files were RMA normalized using Affymetrix expression console.

Metabolic regulation influences cell proliferation. The influence of pyruvate kinase isoforms on tumor cells has been extensively studied, but whether PKM2 is required for normal cell proliferation is unknown. We examine how PKM2 deletion affects proliferation and metabolism in nontransformed, nonimmortalized PKM2-expressing primary cells. We find that deletion of PKM2 in primary cells results in PKM1 expression and proliferation arrest. PKM1 expression, rather than PKM2 loss, is responsible for  ...[more]
