Abstract:
Mounting evidence demonstrates that N(6)-methyladenosine (m(6)A) play critical rolesof m(6)A in the epigenetic regulation, especially for human cancer. The m(6)Amodification is installed by methyltransferase and erased demethylases, leading tothe significant modification for gene expression and cell fate. Here, weinvestigated the biological roles and mechanism of demethylase alkylation repairhomolog protein 5 (ALKBH5) in the non-small cell lung cancer (NSCLC). Resultsrevealed that ALKBH5 was ectopically up-regulated in the NSCLC tissue and cells, andclosely correlated with the poor prognosis. Functionally, ALKBH5 promoted theproliferation and reduced apoptosis of NSCLC cells in vitro, and knockdown of ALKBH5repressed the tumor growth in vivo. Mechanistically, RNA immunoprecipitationsequencing (RIP-Seq) revealed that ALKBH5 targeted the TIMP3. Moreover, ALKBH5repressed TIMP3 mRNA stability and protein production. In conclusion, the presentresearch confirmed the ALKBH5/TIMP3 pathway in the NSCLC oncogenesis progress,providing a novel insight for the epitranscriptome and potential therapeutic targetfor NSCLC.CI - Copyright © 2020.
