Abstract:
Objective To study the expression of N6-methyladenosine(m6A)methyltransferase-like protein 16(METTL16),Ankyrin repeat and SOCS box containing protein 4(ASB13)in elderly breast cancer tissues and their relationship with clinicopathological features and prognosis.Methods 124 elderly patients with breast cancer diagnosed and treated in the Zibo 148 Hospital from January 2019 to January 2021 were selected.Immunohistochemistry(IHC)was used to detect the expression of METTL16 and ASB13 proteins in tissues.Real time fluorescence quantitative PCR(RT-qPCR)was used to detect the expression of METTL16 mRNA and ASB13 mRNA in tissues.Pearson correlation was used for correlation analysis.Survival analysis used Kaplan-Meier curves and Log Rank tests to compare the prognostic differences among patients with different METTL16 and ASB13 expression levels.COX regression analysis was used to analyze the prognostic factors of elderly patients with breast cancer.Results The positive rate of METTL16 in cancer tissue(70.97%)was higher than that in adjacent tissues(8.06%),while the positive rate of ASB13(22.58%)was lower than that in adjacent tissues(72.58%),the differences were statistically significant(χ2=102.642,62.146,all P<0.001).METTL16 mRNA,Snail mRNA and N-cadherin(N-cd)mRNA were higher in cancer tissues than in adjacent tissues,while ASB13 mRNA was lower in adjacent tissues,the differences were statistically significant(t=40.498～48.624,all P<0.001).METTL16 mRNA was positively correlated with Snail mRNA and N-cd mRNA in cancer tissue(r=0.712,0.669,all P<0.001),while ASB13 mRNA was negatively correlated with Snail mRNA and N-cd mRNA(r=-0.734,-0.759,all P<0.001).Compared with TNM stage Ⅰ-Ⅱ and patients with high to medium differentiation,patients with TNM stage Ⅲ and low differentiation had higher positive rate of METTL16 in cancer tissue and lower positive rate of ASB13,the differences were statistically significant(χ2=5.340～10.370,all P<0.05).The 3-year progression free survival rate(73.86%)of the METTL16 positive group was lower than that of the METTL16 negative group(88.89%),the 3-year progression free survival rate(92.86%)of the ASB13 positive group was higher than that of the ASB13 negative group(73.96%),and the differences were statistically significant(Log Rank χ2=4.483,4.882,all P<0.005).METTL16 positive,TNM stage Ⅲ,poor differentiation were risk factors affecting the prognosis of elderly breast cancer,and ASB13 positive was protective factors(Wald χ2=5.056～9.267,all P<0.001).Conclusion METTL16 expression is up-regulated and ASB13 expression is down-regulated in elderly breast cancer,both of which are related to the expression of invasion and metastasis genes,and are new prognostic markers for elderly breast cancer.
