The relationship between the expression of lncRNA LINC00460 and ADAR1 and the prognosis of breast cancer and its diagnostic value

Objective To investigate the relationship between long chain non encoding RNA(lncRNA)LINC00460 and RNA specific adenosine deaminase 1(ADAR1)expression and prognosis of breast cancer and its diagnostic value.Methods The breast tissue and adjacent tissues of 86 breast cancer patients admitted to Shanghai First Maternity and Infant Hospital,Tongji University School of Medicine from May 2019 to May 2020 were retrospectively collected.The qRT-PCR method was used to determine the expression of LINC00460 and ADAR1 in breast cancer tissues and adjacent tissues.The relationship between the expression of LINC00460 and ADAR1 and the clinicopathology of breast cancer patients was analyzed at the same time.The correlation between LINC00460 and ADAR1 was analyzed by Pearson's correlation.Kaplan-Meier survival to analyze the relationship between LINC00460 and ADAR1 and the prognosis of breast cancer patients.Cox multivariate regression analysis of factors affecting the prognosis of breast cancer.Results The relative expressions of LINC00460 and ADAR1 in breast cancer tissues were 4.13±1.24 and 5.07±1.62,which were significantly higher than those in adjacent tissues(0.91±0.27 and 1.03±0.39),the differences were statistically significant(P<0.05).The expressions of LINC00460 and ADAR1 in breast cancer tissues were related to TNM staging,lymph node metastasis,and pathological types(P<0.05).The expression of LINC00460 and ADAR1 in breast cancer tissues was positively correlated(r=0.63,P<0.001).The survival rate of low LINC00460 expression was 91.30%,which was significantly higher than that of high LINC00460 expression(77.50%),the survival rate of low ADAR1 expression was 91.83%,which was significantly higher than that of high ADAR1 expression(74.29%),the differences were statistically significant(P<0.05).LINC00460,ADAR1,TNM staging,pathological type,and lymph node metastasis are independent risk factors for the prognosis of breast cancer.Conclusion LncRNA LINC00460 and ADAR1 are highly expressed in breast cancer tissues and are related to TNM staging,lymph node metastasis,and pathological type.Independent risk factors for the prognosis of breast cancer.
