Objective To investigate the effects of PRPF19 knockdown on the proliferation, migration, and invasion of pancreatic cancer cells. Methods The expression of PRPF19 in pancreatic cancer and normal tissues was analyzed using the GEPIA database. The protein and mRNA expression levels of PRPF19 in pancreatic cancer cells were detected by Western blot and qRT-PCR. Small interfering RNA (siRNA) was used to silence the expression of PRPF19 in pancreatic cancer cells, and the knockdown efficiency was verified by Western blot and qRT-PCR. CCK-8, colony forming, and Transwell assay were used to detect the effects of knockdown of PRPF19 on the proliferation, colony forming, migration, and invasion of pancreatic cancer cells. Results GEPIA analysis showed that PRPF19 was highly expressed in pancreatic cancer tissues compared with normal pancreatic tissues. In comparison with normal pancreatic cells, PRPF19 was highly expressed in various pancreatic cancer cell lines such as MIA PaCa-2 and PANC-1 (P < 0.05). In comparison with the control group, PRPF19 knockdown significantly reduced the proliferation rate, colony forming, cell migration, and invasion of pancreatic cancer cells (P < 0.05). Conclusion PRPF19 knockdown inhibits the proliferation, migration, and invasion of pancreatic cancer cells. PRPF19 may play an important role as an oncogene of pancreatic cancer.

Obj ective To explore the significance of serum lipoprotein and high sensitivity C-reactive protein (hs-CRP)level for the patients with type 2 diabetic nephropathy.Methods 174 patients with type 2 diabetic mellitus were divided into diabetic mellitus group,early diabetic nephropathy group and clinical diabetic nephropathy group,according to the urinary albumin excre-tion rate (UAER).60 healthy individuals were chosen as control group.Lipoprotein (α)[Lp(α)], high density lipoprotein cholesterol (HDL-C),low density lipoprotein cholesterol (LDL-C)and hs-CRP were detected,and the results were analyzed statistically.Results The level of Lp (α), hs-CRP were significantly higher in patients with diabetic mellitus than those in control group (P<0.05).Among the three groups with diabetic mellitus,the level of Lp(α)and hs-CRP got progres-sively significant higher with the increase of UAER (P<0 .05 )whereas the level of HDL-C and LDL-C did not find significant difference(P>0 .05 ).There were linear positive correlation between Lp(α),hs-CRP and UAER levels(r= 0.8069,0.8989).Conclusion Lp(α),hs-CRP levels may be related to the progression of diabetic nephropathy,and their detection had important clinical sig-nificance in early diagnosis and prognostic evaluation of type 2 diabetic nephropathy.
