Abstract:
Objective To investigate the expression of NOP2/Sun RNA methyltransferase family member 2(NSUN2)and protein arginine methyltransferase 5(PRMT5)in retinoblastoma(Rb)tissue and their correlation with the survival prognosis of Rb patients.Methods From February 2019 to February 2021,84 patients with Rb(Rb group)were selected from Beijing Anzhen Hospital Affiliated to Capital Medical University Nanchong Hospital,and 50 normal retinal tissues were used as control group.Real-time fluorescence quantitative PCR(qRT-PCR)was used to detect the levels of NSUN2 mRNA and PRMT5 mRNA in retinal tissues.Kaplan-Meier curve was used to analyze the effect of NSUN2 mRNA and PRMT5 mRNA on the prognosis of Rb patients.COX regression analysis was used to analyze the factors affecting the prognosis of Rb.Results The expression of NSUN2 mRNA(3.11±0.42)and PRMT5 mRNA(2.84±0.39)in Rb cancer tissues were higher than that in the control group(0.80±0.23,0.76±0.20),and the differences were statistically significant(t=35.935,35.033,all P<0.001).The expression of NSUN2 mRNA and PRMT5 mRNA in Rb cancer tissues with tumor diameter≥20mm,undifferentiated and ⅡRC stage D~E were higher than that in tumor diameter<20mm,differentiated tissues and ⅡRC stage A~C cancer tissues,and the differences were statistically significant(t=18.297,141.770,16.693;18.663,139.144,39.947,均P<0.001).The 3-year progression-free survival rate in the high expression group of NSUN2 mRNA was lower than that in the low expression group(60.00%vs 88.64%).The 3-year progression-free survival rate in the high expression group of PRMT5 mRNA was lower than that in the low expression group(56.10%vs 93.02%)(Log rank χ2=13.440,19.501,all P<0.001).Undifferentiated type,ⅡRC stage D-E stage,NSUN2 mRNA high,PRMT5 mRNA high were risk factors affecting the prognosis of Rb patients(Waldχ2=5.923~7.161,all P<0.001).Conclusion The expression of NSUN2 mRNA and PRMT5 mRNA in Rb tissues is increased,which is related to the maximum diameter of tumor,pathological classification and ⅡRC stage,and can be used as a tumor marker to evaluate the survival prognosis of Rb.
