Abstract:
Purpose To investigate correlation of ADP ribosylation-like factor 6 interacting protein 4(ARL6IP4)expression with the pathological characteristics and clinical prognosis in primary colon cancer.Methods The ARL6IP4 mRNA expression in tumor and adjacent normal tissues of 133 colon cancer patients was analyzed by RT-qPCR,and its relationship with tumor location,pathological TNM stage,and 3-year survival prognosis was assessed.Additionally,ARL6IP4 protein expression was analyzed by immunohistochemistry in 30 cases,of which 16 cases were analyzed by immunofluorescence.Results The colon cancer presented significantly higher mRNA and protein levels of ARL6IP4 than adjacent normal tissues(t=4.221,P=5.200 × 10-5;t=7.421,P=3.537 × 10-8).The relative ex-pression level of ARL6IP4 mRNA in colon cancer was positively correlated with pathological TNM stage,N stage and M stage(P＜0.05),and negatively correlated with 3-year cumulative survival probability(P＜0.01).Additionally,sig-moid colon cancer presented significantly higher ARL6IP4 expression than other colon cancers,and at the cellular lev-el,ARL6IP4 was predominantly expressed in the cell nucleus.Conclusion The ARL6IP4 expression in colon cancer is higher than that in adjacent normal tissues,which is closely related to tumor metastasis and clinical prognosis.
