报告题目:三维基因组在生殖干细胞发育过程中的变化规律及其分子机制

报告摘要

高通量染色质结构捕获技术是以细胞核为研究对象,研究全基因组范围内整个染色质在空间位置上的关系,获得高分辨率的染色质调控元件相互作用图谱,全面阐述染色质三维结构。生殖细胞发育中的染色质三维结构重组变化规律的研究有助于深入理解其发育过程中基因的转录调控机制。本次沙龙报告人主要介绍通过Hi-C, ChIP-seq和ATAC-seq等技术,揭示FGSC特有的染色质高级结构及关键调控因子,并描绘FGSC发育过程中的染色质高级结构变化规律。

TITLE:3D Genome Structure Shapes the Recombination Landscape of Chromatin Features in Germline Stem Cell Development

ABSTRACT:

High-throughput chromatin conformation capture (Hi-C) technology focuses on the nucleus, investigating the spatial relationships of chromatin throughout the entire genome, and obtaining high-resolution maps of chromatin regulatory elements' interactions, comprehensively elucidating chromatin's three-dimensional structure. Studying the recombination patterns of chromatin's three-dimensional structure during germline development aids in a deeper understanding of the transcriptional regulatory mechanisms of genes during its developmental process. The speaker mainly introduces the chromatin's higher-order structure unique to the female germline stem cells (FGSCs) and key regulatory factors through techniques such as Hi-C, ChIP-seq, and ATAC-seq, and outlines the patterns of chromatin's higher-order structural changes during FGSC development.
