Abstract
Objective To explore the expression of P53 and mettl-9 gene in colon cancer tissues and inflammation tissues and normal adjacent tissues and study its relationship with colon cancer.Methods The morphologic situation of histiocyte after H.E.stained was observed.The real-time fluorescent quantitative PCR was applied to detect the gene expression of P53 and METFL-9.Results The expression of P53 gene in inflammation tissues was significantly higher than that in cancer tissues and adjacent tissues(P ＜0.05).The expression of P53 gene in cancer tissues was significantly lower than adjacent tissues and infiammation tissues.METTL-9 gene expression in inflammation tissues was significantly lower than cancer tissues and adjacent tissues(P ＜0.05).In cancer tissues,P53 gene and METFL-9 gene were negative related.Conclusions The mutations of P53 gene played an important role in the course of colon cancer,its downstream gene METTL-9 was highly expressed in colon cancer,and the 9-methyl-converting enzyme which produced by transcription and translation might lead gene hypermethylation in the colon cancer,and thereby promoted the development of colon cancer.
