Fig. 2From: CK1α overexpression correlates with poor survival in colorectal cancerTumor differentiation-dependent investigation of CK1α RNA expression. a Box plot representing group comparison of relative CK1α RNA expression in low-grade and high-grade CRC patients. b Kaplan-Meier plot displaying the overall survival of Grade 3 and Grade 4 tumors of CRC patients, divided according to relative CK1α RNA expression. *** p < 0.001. CK1α RNA expression in colorectal tumor tissue of all grades was relatively quantified by qPCR using specific primers. HPRT gene served as reference gene. Graphs were created using IBM SPSS Statistics 20Back to article page
