Effect of Heat stress on m6A modification in CaSki cell
Ontology highlight
ABSTRACT: N6-methyladenosine (m6A) occurs extensively on multiple RNA species and is the most abundant internal modification of eukaryotic messenger RNA (mRNA). RNA m6A methylation is a dynamic and reversible process subjected to regulation by three categories of m6A modifier proteins, including m6A methyltransferases/writers (e.g., METTL3/14 methyltransferase complex and METTL16), m6A demethylases/erasers (e.g., FTO and ALKBH5) and m6A binding proteins/readers (e.g., YTH family proteins and IGF2BPs). The dynamic and adjustable nature makes m6A a key regulator in RNA metabolism, and the fate of m6A-modified RNA is modulated by m6A readers. Previous studies have demonstrated that fever can benefit survival of cancer patients, and currently hyperthermia (elevating body temperature beyond normal) is either administered alone or in combination with radiotherapy or chemotherapy to treat various neoplasms with unclear mechanisms. Accruing evidence has revealed favorable effects of fever/hyperthermia in cancer treatment through affecting the properties of oncogenic proteins (e.g., stability, posttranslational modification, ability to interact with other molecules). Accordingly, we sought to investigate whether and how heat stress affects cancer development by m6A modification.
