Abstract
N6-methyladenosine (m6A) plays a role in the development of tumors. However, the specific role of VIRMA, an RNA methyltransferase, in pancreatic ductal adenocarcinoma (PDAC) remains unclear. This study shows that VIRMA expression is elevated in PDAC. Increased VIRMA levels promoted PDAC growth and spread, while reducing VIRMA expression slowed these processes. VIRMA facilitated SLC43A2 mRNA degradation through an m6A-YTHDF2 pathway. The resulting decrease in SLC43A2 reduced phenylalanine absorption and oxidative stress, further driving PDAC progression. Furthermore, alcohol increased C/EBP β expression, which bound to VIRMA's promoter, enhancing its transcription. These findings suggest a connection between alcohol consumption, m6A modifications, and phenylalanine absorption in PDAC progression, offering a new approach to combat this disease.
期刊介绍：
Oncogene is dedicated to advancing our understanding of cancer processes through the publication of exceptional research. The journal seeks to disseminate work that challenges conventional theories and contributes to establishing new paradigms in the etio-pathogenesis, diagnosis, treatment, or prevention of cancers. Emphasis is placed on research shedding light on processes driving metastatic spread and providing crucial insights into cancer biology beyond existing knowledge.
Areas covered include the cellular and molecular biology of cancer, resistance to cancer therapies, and the development of improved approaches to enhance survival. Oncogene spans the spectrum of cancer biology, from fundamental and theoretical work to translational, applied, and clinical research, including early and late Phase clinical trials, particularly those with biologic and translational endpoints.
