Abstract:
N6-methyladenosine (m6A) is the most prevalent internal modification in mammalian mRNAs and methyltransferase-like 3 (METTL3) is a vital methyltransferase in m6A modification. Here, this study tries to discover the regulatory role of METTL3 and its mechanism in the breast cancer tumorigenesis. Results found that METTL3 was up-regulated in the breast cancer tissue and cells. In vivo and vitro, METTL3 knockdown could decrease the methylation level, reduce the proliferation, accelerate the apoptosis and inhibited the tumor growth. Moreover, we found that Bcl-2 acted as the target of METTL3, thereby regulating the proliferation and apoptosis of breast cancer. This study could reveal the potential mechanism of m6A modification in the breast cancer tumorigenesis, providing potential drug targets in the treatment.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
