值得关注的是,SpCas9复合物完成切割后仍滞留于靶点并掩盖断裂DNA末端【5-6】,而Cas12a,包括LbCas12a、AsCas12a和FnCas12a, 在切割靶点后呈现靶点不对称滞留模式——仅结合PAM近端的DNA末端(PAM-proximal end,PPE),而释放PAM远端的DNA...
在一些真核生物中,DNA甲基化发生在基因编码区,称为基因体甲基化(gene body methylation,GbM)。尽管DNA甲基化在转座子和重复DNA沉默中的作用已得到很好的表征,但基因体甲基化与转录抑制无关,其生物学重要性尚不清楚。 2023年10月12日,美国加州大学伯克利分校植物与微生物生物学系Ben P. Williams团队在《Genome Bio...
Borzoi decodes the complex DNA signals governing gene regulation Borzoi is a deep learning model that predicts RNA sequencing coverage across each exon of every human gene, across different cells and tissues, based on DNA sequence alone.
3a). Comparing across all screens, we found that the cell type chosen for infection is the dominant factor determining screen hit overlap, rather than differences in viral strain, MOI or timeline of genomic DNA harvest. A large cluster of gene hits enriched across at least three other screens...
Williams团队在《Genome Biology》杂志上发表题为“Dynamic DNA methylation turnover in gene bodies is associated with enhanced gene expression plasticity in plants”的研究论文,该研究以模式植物拟南芥为研究对象,通过WGBS、EM-seq、RNA-seq等多组学分析揭示了植物genebody中DNA甲基化动态变化与基因表达可塑性增强...

MAGPIE prediction on gene mutations that cause Mendelian diseases Next, we applied MAGPIE to four genes curated with a large number of known pathogenic mutations causing different Mendelian diseases (Methods). For all the four genes tested, i.e., ATP7B, CFTR, FBN1, and LMNA, MAGPIE was able...
