为探究乳腺癌对缺氧的适应机制,研究人员研究 HIF1α-ATF3-P4HA1 轴,发现其促进癌细胞侵袭,为治疗提供靶点。 在肿瘤的 “小世界” 里,乳腺癌细胞正经历着一场特殊的 “考验”—— 缺氧。肿瘤不断生长,内部的代谢和血管出现异常,导致缺氧区域逐渐形成。缺氧就像一个幕后 “操纵者”,它能改变癌细胞的各种行为,比如让癌细胞更容易从原发部位 “跑” 到身体其他地方,也就是发生侵袭和转移,还能帮助 ...
当研究人员第一次绘制人类基因组图谱时,他们震惊地发现只有2%的DNA是编码蛋白质的"明码区段(coding regions)",其余98%的"暗物质(dark matter)"——也就是非编码区(noncoding ...
Here, cell biology and genomic methods revealed that the chromatin factors CTCF and cohesin are key organizers of chromatin–speckle interactions. This organization enhanced speckle-proximal gene ...
Using single-molecule tracking of cohesin and CTCF during zebrafish embryogenesis, the molecular kinetics underlying chromatin architecture formation was revealed and gradual emergence of ...

而且,在葡萄糖限制培养基中培养 25 天的细胞,其线粒体数量最多。通过 ImageJ 软件分析得到的平均 CTCF 值也显示,葡萄糖限制培养基中培养 25 天的细胞荧光水平更高,这一差异具有统计学意义(P<0.05)。这表明葡萄糖限制能够促进线粒体的生成和分布。
