PEPCK expression levels in patients with rectal cancer. (a) Western Blot analysis was performed to determine the PEPCK expression levels in 122 patients with rectal cancer. The patients were divided into poor and good response groups according to their response to chemoradiotherapy (see Methods). The PEPCK expression levels in SNU-C4 and HCT-116 were used as controls. (b) PEPCK expression levels were linked to the chemoradiotherapy response. The PEPCK expression levels were normalized to the actin expression levels.
