YTHDC2 control of gametogenesis requires helicase activity but not m6A binding

Yuhki Saito et al.

Summary: In this study, the researchers investigated how the N-6-methyladenosine (m(6)A) reader and RNA helicase YTHDC2 regulate gene expression during meiosis. They found that YTHDC2 can bind transcripts independent of m(6)A status and regulate gene expression through distinct mechanisms during multiple stages of meiosis. Mutation of the m(6)A-binding pocket of YTHDC2 had no effect on gametogenesis, suggesting that YTHDC2's function is m(6)A-independent. However, mutation in the ATPase motif of YTHDC2 blocked meiotic prophase I progression, causing sterility.

The m6A reader YTHDC2 is essential for escape from KSHV SOX-induced RNA decay

Daniel Macveigh-Fierro et al.

Summary: N6-methyladenosine (m6A) modifications play a significant role in modulating viral and host transcripts during Kaposi's sarcoma-associated herpesvirus (KSHV) lytic infection. The presence of m6A modification in IL-6 mRNA confers resistance to viral endoribonuclease SOX, and this modification recruits m6A reader YTHDC2 for the escape of the IL-6 transcript.

Identification of N6-methyladenosine-related lncRNAs for patients with primary glioblastoma

Wen Wang et al.

Summary: This study identified four m(6)a-related prognostic lncRNAs in patients with pGBM, with the low-risk group showing longer survival compared to the high-risk group. Different m(6)a statuses were associated with histologic grade and survival outcomes in glioma. Functional annotation revealed enrichment of genes related to immune response, apoptosis, and RNA metabolism regulation.

N6-Methyladenosine Reader Protein YT521-B Homology Domain-Containing 2 Suppresses Liver Steatosis by Regulation of mRNA Stability of Lipogenic Genes

Bing Zhou et al.

Summary: In this study, it was found that m(6)A enrichment and mRNA expression of lipogenic genes were increased in leptin-receptor-deficient mice. The m(6)A reader, Ythdc2, was down-regulated in obese mice and NAFLD patients, and its suppression in lean mice led to TG accumulation while overexpression in obese mice improved liver steatosis and insulin resistance. This suggests that Ythdc2 plays a crucial role in regulating hepatic lipogenesis and TG homeostasis, presenting a potential target for treating obesity-related NAFLD.

N6-methyladenosine reader YTHDC2 and eraser FTO may determine hepatocellular carcinoma prognoses after transarterial chemoembolization

Jiandong Liu et al.

Summary: Transarterial chemoembolization (TACE) has improved overall survival of unresectable hepatocellular carcinoma (HCC) patients, but some show no response to TACE. Functional SNPs in m(6)A-regulating genes, particularly in YTHDC2 and FTO, were found to be associated with prognosis in TACE-treated HCC patients in a Chinese Han population. This suggests m(6)A-regulating genes could be potential targets to enhance therapeutic strategies for unresectable HCC patients.

N6-methyladenosine modification of HCV RNA genome regulates cap-independent IRES-mediated translation via YTHDC2 recognition

Geon-Woo Kim et al.

Summary: The m(6)A modification of the HCV RNA genome plays a crucial role in IRES-dependent translation, with the m(6)A reader protein YTHDC2 being essential for recognizing and supporting HCV translation initiation. This study highlights the functional significance of m(6)A modification and YTHDC2 in HCV IRES-dependent translation initiation, providing potential therapeutic targets for interfering with the infectious process.

Linking the YTH domain to cancer: the importance of YTH family proteins in epigenetics

Rongkai Shi et al.

Summary: N6-methyladenosine (m6A) is the most prevalent and reversible modification of mRNA in mammalian cells, and YTH family proteins, as the main readers of m6A modification, play important roles in m6A research by recognizing and binding m6A-containing RNA through their YTH domain. The crystal structure of the YTH domain has been resolved, highlighting the crucial roles of conserved residues in the specific recognition of m6A-modified RNAs. Upstream and downstream targets have been identified in different cancer types, emphasizing the significance of YTH family proteins in m6A regulation.

N6-methyladenosine RNA methylation regulators contribute to the progression of prostate cancer

Qunying Wu et al.

Summary: The study found that METTL3, METTL14, ALKBH5, FTO, YTHDC2, YTHDF1, and YTHDF2 were abnormally expressed in prostate cancer and related to Gleason classification. Changes in m(6)A levels may contribute to the development and progression of prostate cancer.
