RASSF1A and RASSF1A methylation′s relationship with breast cancer / 实用肿瘤学杂志

ABSTRACT

Breast cancer is one of the most common malignant tumors in women.Early diagnosis plays a very important role in the treatment of breast cancer.Recently,with the development of epigenetics,it gives us a new orientation for early detection for cancers.The most understood mechanism of epigenetics is DNA methyla-tion.Ras associated domain family 1A gene(RASSFlA)promoter methylation occurres in tumor′s early stage,and have a statistically concern with tumor′s TNM stage,invasiveness and outcomes.Moreover,DNA methylation can be reversed,so RASSF1A can be a promising candidate for early breast cancer detection biomarker,and can be a potential orientation for breast cancer treatment.
