Abstract
Viral RNAs have been known to contain N6-methyladenosine (m6A) modifications since the 1970s. The function of these modifications remained unknown until the development of genome-wide methods to map m6A residues. Increasing evidence has recently revealed a strong association between m6A modifications and plant viral infection. This highlight introduces advances in the roles of RNA m6A modifications in plant-virus interactions.

Abstract
BACKGROUND Acute-on-chronic liver failure (ACLF) is a syndrome with both high prevalence and mortality. However, the underlying mechanisms remain elusive and there is no effective therapeutic approach available. Here we aim to uncover novel molecular mechanisms of ACLF and identify potential therapeutic targets. METHOD We performed integrative analysis of 3 transcriptomic datasets and subsequent bioinformatic analysis aiming for potential genes of significance in ACLF development, identifying a critical role of IGF2BP3/HIF1A signaling in development of ACLF. Expression of molecules in IGF2BP3/HIF1A pathway and hepatocyte reprogramming markers in clinical samples were then determined by western blot and quantitative PCR. N6-methyladenosine (m6A) RNA modification of HIF1A was analyzed by m6A dot assay and PCR following m6A-antibody precipitation. The molecular mechanisms among IGFBP3, HIF1α and YAP1 were further validated by gene overexpression and knockdown experiments in HepG2 and Hep3B cells. Cell phenotypes of hepatocyte reprogramming were determined by EdU staining, sphere formation assay and immunoblotting of relevant markers. RESULTS Our data demonstrated that IGF2BP3 recognized m6A modification in HIF1A mRNA as an m6A reader, thereby promoting expression of HIF1A by increasing RNA stability. HIF1A activated Rho GTPases (RhoA) and suppressed phosphorylation of YAP via inhibiting LATS1/2, promoting translocation of non-phosphorylated YAP into the nucleus, resulting in fetal liver programme and ultimate hepatic injury in ACLF patients. CONCLUSION We reveal a novel molecular mechanism that IGF2BP3/HIF1A/YAP signaling promotes hepatocyte reprogramming, causing hepatic injury in ACLF. Our study provides potential targets for treatment of ACLF.

Abstract
This study focuses on the function of WTAP in esophageal squamous cell carcinoma (ESCC) samples and cell lines. The results showed that WTAP expression in ESCC tissues was significantly upregulated in 78.1% (57 of 73) of the ESCC tissues at the protein level compared with adjacent non-cancerous tissues via immunohistochemical staining. The WTAP protein expression level was positively correlated with the lymph node metastasis and TNM stage, and patients with higher WTAP protein expression level exhibited a shorter overall survival interval. Knocking down WTAP significantly reduced cell proliferation and migration but promoted cell apoptosis of TE-1and KYSE150 cells. Moreover, WTAP inhibition reduced the expression of ki67 and Snail related to cell proliferation and migration but increased the expression of Bax and Caspase-3 which were involved in cell apoptosis. In conclusion, our results suggest that the WTAP, a potential biomarker of ESCC, maybe play an important role in ESCC-genesis through regulating expression of genes related to cell proliferation, migration and apoptosis.
