Web研究揭示了ecDNA与细胞恶性转变之间的关联(图片来源:参考资料[1]) 此外,研究还发现ecDNA在TP53突变之后出现,但独立于全基因组复制、染色体碎裂等染色体变化。如果前后两次检测时,细胞状态相近,那么ecDNA的拷贝数也不会有明显增长;相反,当细胞的异常逐渐积累,ecDNA的拷贝数和结构复杂 ... Web综上所述, 本研究首次从ecDNA层面阐明HPV致癌机制,发现HPV整合形成的超级增强子以ecDNA的形式发挥全基因组转录调控,填补了宫颈癌在ecDNA方向上的研究空白。 由于HPV-human ecDNA的特殊性(仅存在于HPV感染/整合的病变细胞),因此在诊断和靶向治疗方面具有巨大的应用前景。 它即可作为诊断标记物,也可作为治疗靶点。 在本研究中 …
