【导读】外转录组修饰,尤其是N6-甲基腺苷(m6A),是基因表达的关键调控因子,影响着RNA的稳定性、剪接和翻译等过程。从Nanopore直接RNA测序(DRS)数据中检测m6A的传统计算方法受限于对实验验证标签的依赖,往往会导致对修饰位点的低估。在 ...
直接RNA测序(DRS)技术 ... CXCL10 mRNA的稳定性通过YTHDF1介导的m6A位点识别维持。 pum6a不仅扩展了m 6 Anet的功能,还通过整合电信号和碱基配对特征 ...
【导读】N6-甲基腺苷(m6A)修饰在真核细胞中是一种重要的表观遗传调节因子,在肿瘤发生和癌症进展中发挥着重要作用。然而,m6A 调控在胃癌(GC)中的详细生物学功能和潜在机制尚不清楚。1月15日,中山大学陈永明研究团队在期刊《Molecular ...
环状RNA是RNA分子经过5 '和3 '端共价反向拼接而形成的,在许多生理和病理过程中发挥重要调控作用。然而,环状RNA在肝癌和肝癌干细胞中的作用尚 ...
尽管对抗体的蛋白质水平研究广泛,但对抗体的RNA转录后修饰如何影响抗体稳态的研究却相对缺乏。 来自清华大学的研究人员研究了抗体分泌细胞(ASCs)中IgG1 mRNA的转录后修饰对IgG1抗体的产生和稳态有何影响。研究发现,IgG1 mRNA的m6A修饰和多聚腺苷酸化对于 ...
Binding of both the RNA-binding protein TDP-43 and the m6A RNA modification chemical tag has been found to be altered in genes that are dysregulated in HD. Further, TDP-43 pathology, classically ...
A major tool in these studies is single-cell epitranscriptomics, which studies RNA modifications like m6A methylation, which can significantly influence gene regulation and are important in ...
City of Hope conducted RNAseq analysis of patient samples with B-cell acute lymphoblastic leukemia (B-ALL), which revealed that among the m6A machinery genes, YTHDF2, which encodes YTH ...
A study reveals how hydrogen peroxide (H2O2) signaling regulates tomato ripening through the redox modification of RNA demethylase SlALKBH2. This modification stabilizes SlALKBH2, enhancing its role ...
