Expression Data from 22 human pancreatic cancer cell lines grown in triplicates +/- MEK inhibitor CI-1040

ABSTRACT: Analysis of mRNA profiles after MEK1/2 inhibition in human pancreatic cancer cell lines reveals pathways involved in drug sensitivity. We used microarrays to find gene expression patterns associated with drug response and also identified genes regulated by the MAP kinase pathway 22 pancreatic cell lines were grown in culture media containing serum and either treated with vehicle control or CI-1040 for 24 hours

Mutationally activated KRAS, detected in approximately 90% of pancreatic ductal adenocarcinomas (PDA), has proven an intractable pharmacologic target to date. Consequently, efforts to treat KRAS-mutated cancers are focused on targeting RAS-regulated signaling pathways. In mouse models, expression of BRAF(V600E) combined with dominant-negative TP53 elicits PDA, and pharmacologic blockade of mitogen-activated protein/extracellular signal-regulated kinase (MEK) inhibits proliferation of human PDA-d  ...[more]
