abstractText | P21 activated kinase 1 (PAK1) enhances colorectal cancer (CRC) progression by stimulating Wnt/beta-catenin and Ras oncogene, which promote CRC survival via stimulation of hypoxia-inducible factor 1alpha (HIF-1alpha). The aim of this study was to assess the mechanism involved in the stimulation by PAK1 of CRC survival. PAK1 promoted CRC cell survival by up-regulation of HIF-1alpha. PAK1 was over-expressed and hyper-activated in tumors of ApcDelta(14/+) mice, which was correlated with over-expression of HIF-1alpha and beta-catenin. Inhibition of PAK1 decreased tumor growth and the expression of HIF-1alpha and beta-catenin in tumors of ApcDelta(14/+) mice, and suppressed xenograft tumor survival in SCID mice. These findings indicate that PAK1 stimulates CRC survival by up-regulation of HIF-1alpha. |
