Abstract:

Metastasis is an important cause of poor survival and prognosis of patients with breast cancer; however, our current knowledge of its underlying molecular mechanism is limited. RNA N6-methyladenosine (m6A) modification is a novel mechanism of epi-transcriptional regulation of gene expression at the posttranscriptional level that has attracted much attention in the past decade. Its important role in malignant biology such as breast cancer metastasis is emerging now. The m6A modification of specific RNA is dynamically regulated by the methyltransferase complex (MTC) and RNA demethylases such as fat mass and obesity-associated protein (FTO) . The biological function of RNA that has undergone the m6A modification depends on the interpretation of its ''reader'' protein. This review summarizes the latest research progress in the role of dysregulated various components of RNA m6A modification including m6A ''writers'', ''erasers'' and ''readers'' in breast cancer metastasis as well as their underlying molecular mechanisms. Meanwhile, the future directions of development of precise detection of dysregulated RNA m6A modification in breast cancer metastasis and new targeted therapy strategies based on novel molecular mechanisms are also prospected.

Key words: N6-methyladenosine (m6A), RNA m6A modification, Breast cancer, Tumor metastasis, Epitranscriptome
