ABSTRACT
Objective To study the detection of Na+/H+exchanger regulatory factor 3(NHERF3) protein expression in renal carcinoma and its correlation with malignant biological behavior. Methods Renal clear cell carcinoma and their adjacent tissues of forty- eight patients were collected. Immunohistochemical method was used to detect the positive expression of NHERF3 protein,and specific expression was detected by Western-blot.Patients were further divided into high NHERF3 group and low NHERF3 group according to median expression of NHERF3 protein,and each group had 24 cases.The expressions of proliferation,invasion and autophagy genes in tumor tissues were detected by fluorescent quantitative PCR.Results The positive rate of NHERF3 protein and the expression of NHERF3 protein in renal carcinoma tissue was significantly lower than that in paracancerous tissue(P<0.05).Expressions of proliferation genes such as k-Ras,c-Myc,TRPC1 mRNA in low NHERF3 group were higher than those in high NHERF3 group141.74 ± 18.95 vs. 100.00 ± 0.00, 135.88 ± 16.32 vs. 100.00 ± 0.00, 137.21 ± 16.98 vs.100.00 ± 0.00;MIIP,FOXO1 mRNA levels were lower than those in high NHERF3 group 43.19 ± 5.88 vs. 100.00 ± 0.00, 38.76 ± 4.51 vs. 100.00 ± 0.00; expressions of invasion genes such as CD74, Fascin, MACC1, TRPM8 mRNA were significantly higher than those in high NHERF3 group152.18 ± 17.64 vs. 100.00 ± 0.00, 146.29 ± 17.63 vs. 100.00 ± 0.00, 139.76 ± 15.82 vs. 100.00 ± 0.00,150.47 ± 17.95 vs.100.00 ± 0.00;expressions of autophagy genes such as Beclin-1,LC3 mRNA were significantly lower than those in high NHERF3 group 63.21 ± 7.09 vs. 100.00 ± 0.00, 56.28 ± 7.15 vs. 100.00 ± 0.00; EZH2 mRNA level was higher than that in high NHERF3 group159.47 ± 17.82 vs.100.00 ± 0.00,and there were significant differences(P<0.05).Conclusions The positive rate of NHERF3 protein expression and the amount of protein expression in renal carcinoma tissue is increased, and the specific expression is closely related to tumor proliferation, invasion and activity of autophagy.
