To investigate the changes in epigenetic landscape of HT29 cells upon coculture with the Histone and m6A mRNA modifications were examined by biochemical and NGS-based methods including western blotting, colorimetric assays, ChIP-Seq and direct mRNA sequencing. LC-MS was performed to identify secretome. In cocultured HT29 cells global enrichment of H3K9ac and H3K4me3 and depletion of H3K9me3 mark was observed; mean genic positional signals showed depletion of H3K9ac and H3K4me3 at the TSS but enrichment in the upstream region; m6A methylation was altered in mRNAs corresponding to specific gene pathways; HU protein interacts with histone H3. can epigenetically alter specific genetic pathways in human intestinal cells.
研究共培养 HT29 细胞后表观遗传景观的变化,通过生化和基于 NGS 的方法(包括 Western blot、比色测定、ChIP-Seq 和直接 mRNA 测序)检测组蛋白和 m6A mRNA 修饰。LC-MS 用于鉴定分泌组。在共培养的 HT29 细胞中观察到 H3K9ac 和 H3K4me3 的全局富集以及 H3K9me3 标记的耗尽;平均基因位置信号显示在 TSS 处 H3K9ac 和 H3K4me3 的耗尽,但在上游区域富集;对应于特定基因途径的 mRNA 中的 m6A 甲基化发生改变;HU 蛋白与组蛋白 H3 相互作用。可以在人肠道细胞中表观遗传地改变特定的遗传途径。
