Abstract:
Objective To analyze the expression levels of miR-27a-3p mRNA and Yes-associated protein 1(YAP1)mRNA in breast cancer,and to explore their relationships with clinicopathological features and the survival prognosis of patients.Methods A total of 130 breast cancer patients who underwent mastectomy in our hospital between January 2019 and January 2021 were enrolled.The expression levels of miR-27a-3p and YAP1 mRNA in breast tumor tissues and adjacent normal breast tissues were assessed by qRT-PCR.Furthermore,the relationships between their expression and clinicopathological features,as well as the survival prognosis of patients,were investigated.Results Compared with adjacent normal breast tissues,the expression of miR-27a-3p mRNA in breast tumor tissues was lower(P<0.05),while that of YAP1 mRNA was higher(P<0.05).A negative correlation was observed between the expression of miR-27a-3p mRNA and YAP1 mRNA in breast tumor tissues(r=-0.456,P<0.05).The expression of miR-27a-3p mRNA was correlated with tumor diameter,histological grade,tumor staging by the TNM system,lymph node metastasis,and vascular invasion in patients with breast cancer(P<0.05).The YAP1 mRNA expression was correlated with histological grade,tumor staging by the TNM system,lymph node metastasis,and vascular invasion(P<0.05).Kaplan-Meier survival analysis revealed that the 3-year overall survival rate of the miR-27a-3p low-expression group was 71.60%(48/67),which was lower than the 91.50%(54/59)of the miR-27a-3p high-expression group(log-rank x2=8.211,P=0.004).The 3-year overall survival rate of the YAP1 high-expression group was 73.80%(45/61),lower than that of the YAP1 low-expression group(87.70%,57/65)(log-rank x2=4.429,P=0.035).Multivariate regression analysis indicated that lymph node metastasis(hazard ratio[HR]=1.409;95%CI,1.057-1.644;P=0.046),vascular invasion(HR=1.541;95%CI,1.076-1.869;P=0.045),low miR-27a-3p mRNA expression(HR=0.593;95%CI,0.388-0.925;P=0.018),and high YAP1 mRNA expression(HR=0.628;95%CI,0.405-0.912;P=0.022)were relevant factors affecting the 3-year overall survival of patients with breast cancer.Conclusion A significant downregulation of miR-27a-3p mRNA and upregulation of YAP1 mRNA are observed in breast tumor tissues.The low expression of miR-27a-3p mRNA and the high expression of YAP1 mRNA are associated with adverse clinicopathological features and poor survival prognosis,and are risk factors affecting the 3-year overall survival of patients with breast cancer.They show promise as new potential therapeutic targets for breast cancer.
