Abstract:
Objective To investigate the expression of Member RAS Oncogene Family(RAB10)in pancreatic cancer(PAAD)and its effects on the proliferation,migration,invasion and apoptosis of SW1990 cells(human pancreatic cancer cells).Methods The expression of RAB1 0 mRNA in PAAD tissues wasanalyzed by the cancer gene database GEPIA(Gene Expression Profiling Interactive Analysis)and TCGA(The Cancer Genome Atlas).Cox regression analysis was used to detect relationship between RAB10 mRNA expression and the prognosis of pan-creatic cancer patients.We targeted small interfering RNA(R4B10-siRNA)targeting RAB10 as the silence group,and constructed an overexpression plasmid(RAB10-OE)for overexpression of RAB10 as the overexpression group.The effects of silencing and overexpressionweredetected by Q-PCR;protein expression levelsweredetected by West-ern blot.EdUcellproliferation test,wound healing test,Transwelltestand flow cytometry test were used to determine the effects of RAB10 on the proliferation,migration,invasion and apoptosis of SW1990 pancreatic cancer cells.Re-sults RAB10 mRNA expression in PAAD tissues was higher than that innormal pancreatic tissues(P＜0.05).The results of EdUcellproliferation testshowed that the proliferation rate of SW1990 cells in the RAB10-OE group was higher thanthat in the control group,and the proliferation rate of SW1990 cells in the RAB10-siRNA group was lower than that inthe control group(P＜0.05).The results of the Transwell test and wound healing test showed that the invasion rate and mobility rate of RAB10-OE group were higher thanthose of the control group,and the mobility and invasion rate of RAB10-siRNA group were lower than those of the control group(P＜0.05).The re-sults of flow cytometry test showed that the apoptosis rate was lower in the RAB10-OE group than the control group,and the apoptosis rate in the RAB10-siRNA group was higher than the control group(P＜0.05).The median sur-vival time of RAB10 high expression group was significantly lower than that of RAB10 low expression group(P＜0.05).Cox regression analysis showed that clinical grade,T stage,M stage and RAB10 mRNA expression were re-lated to survival and prognosis of pancreatic cancerpatients(P＜0.05).Multivariate Cox regression analysis showed that the expression level of RAB10 mRNA was the independent risk factor affecting the prognosis of pancre-atic cancer patients(P＜0.05).Conclusion RAB10 is highly expressed in PAAD tissues and RAB10 can pro-mote the proliferation of pancreatic cancer cells,accelerate the ability to invade and migrate,and inhibit the apop-tosis of pancreatic cancer cells.RAB10 is an independent risk factor for survival prognosis in patients with pancreat-ic cancer.
