DHX32 and neoplasm: Although we did not observe significant differences of the positive rate of DHX32 gene expression between the groups according to each parameter (data not shown), our results suggested that the level of DHX32 gene expression in colorectal carcinoma was significantly associated with tumor location, lymph gland metastasis, tumor nodal status, differentiation grade and Dukes' stage (P < 0.05) (Figure 2).
