Gene expression profiling of AC9 overexpression in 393P mice cells

ADCY9 encodes AC9, which is 1 of 9 transmembrane AC isoforms (AC1-9) that catalyze the synthesis of cyclic AMP from ATP and are regulated primarily by heterotrimeric G-protein-coupled receptors. We ectopically expressed AC9 in 393P cells and found that, relative to empty vector controls, the AC9 transfectants had higher cyclic AMP levels and were more migratory and invasive in Boyden chambers. We examined the prognostic value of an AC9-regulated gene expression signature derived from 393P_AC9 cells and 393P_vector cells. We probed a compendium of 1,586 clinically annotated human lung adenocarcinomas for the manifestation of the AC9 gene signature and found that the manifestation of the signature was correlated with a significantly shorter duration of survival.
