Analysis of Serum Furin,TGF-β,VEGF and netrin-1 Levels Expression and Polymorphism of r2071410 C/T Locus in the Furin Gene P1 Promoter Region in Patients with Different r-AFS Stages of Endometriosis
Objective To investigate Furin,tumor growth factor-β(TGF-β),vascular endothelial growth factor(VEGF),neuron towards axon guidance factor-1(netrin-1)level expressions and polymorphism of Furin gene P1 promoter r2071410 locus C/T in endometriosis(EMT)patients with different r-AFS stages,and explore the correlation with the incidence of EMT in Shenzhen.Methods A total of 102 patients diagnosed with EMT from May 2021 to January 2023 in the People's Hospital of Longhua,Shenzhen were selected as EMT group,and the EMT group was divided into stage Ⅰ to Ⅱ group and stageⅢ to Ⅳ group according to r-AFS staging method.At the same time,78 non-EMT patients were collected as control group.The levels of serum Furin,TGF-β,VEGF and netrin-1 were detected by enzyme-linked immunosorbent assay(ELISA),and the polymorphism of the r2071410 C/T locus in the P1 promoter region of Furin gene was analyzed by reverse transcription-real time quantitative polymerase chain reaction(RT-qPCR).Results The levels of Furin(140.84±47.02pg/ml),TGF-β(376.46±82.36ng/L)and VEGF(167.67±53.02ng/L)in EMT group were higher than those in control group(55.49±13.67pg/ml,216.37±15.04ng/L,102.27±8.45ng/L),while the level of netrin-1(48.37±15.20pg/ml)was lower than that of the control group(165.85±15.63pg/ml),with significant differences(t=28.409,20.347,16.915,36.653,all P＜0.05).The levels of Furin(192.41±20.62pg/ml),TGF-β(452.61±72.03ng/L)and VEGF(201.84±28.01ng/L)in patients with stage Ⅲ to Ⅳ were higher than those in patients with stage Ⅰ to Ⅱ(78.05±16.54pg/ml,283.75±56.92ng/L,126.07±19.35ng/L),while the level of netrin-1(37.95±11.34pg/ml)was lower than that of stage Ⅰ to Ⅱ(61.05±9.52pg/ml),with significant differences(t=31.071,18.054,19.183,21.625,all P＜0.05).Pearson/Spearman correlation analysis showed that Furin was positively correlated with levels of TGF-β and VEGF and clinical stage(r=0.614 9,0.752 6,0.790 5,均 P＜0.05),but negatively correlated with netrin-1 level(r=-0.670 1,all P＜0.05).The TT genotype and T allele frequencies at r2071410 C/T locus of Furin gene P1 promoter in EMT group(42.16％,55.39％)were higher than those in control group(7.69％,19.87％),while the TT genotype and T allele frequencies at stages Ⅲ to Ⅳ(51.79％,65.18％)were higher than those at stage Ⅰ to Ⅱ(30.43％,43.48％),and the differences were statistically significant(x2=26.500,46.472,4.721,9.626,all P＜0.05).The Furin level of patients with different genotypes in EMT group was different(F=51.286,P＜0.001),in which the Furin level of TT genotype(216.29±68.53pg/ml)was higher than that of CC(83.04±21.37pg/ml)and CT genotype,(89.18±20.95pg/ml),and the differences were statistically significant(t=27.146,25.719,all P＜0.01),but there was no significant difference between CC and CT genotypes(t=1.326,P＞0.05).Conclusion The level of Furin in EMT patients was increased,and it was certainly correlated with the levels of TGF-β,VEGF,netrin-1 and clinical stage.Meanwhile,the r2071410 C/T locus in the promoter region of Furin gene P1 showed a polymorphic distribution,in which the Furin level increased more significantly in patients with TT genotype,which may be related to the incidence of EMT in Shenzhen area.
