Modification of Maternally Defined H3K4me3 Regulates the Inviability of Interspecific Xenopus Hybrids
Qi Long#, Kai Yan#, Chendong Wang, Yanling Wen, Furong Qi, Hui Wang, Peng Shi, Xingguo Liu, Wai Yee Chan, Xuemei Lu*, and Hui Zhao*
Key words
H3K9me3 ,LINE-1, KDM4B, tumorigenesis, DNAdamage
本研究利用两种爪蟾的独特的种间杂交体系,进一步探讨了种间杂交中染色质不亲和性的机制。该研究强调了母系定义的H3K4me3修饰,通过P53信号通路调控胚胎早期发育,在生殖隔离和维持杂交种亚基因组平衡的重要性。研究非洲爪蟾杂交种并破译物种形成的机制将加深我们对生殖隔离、物种进化和调节早期胚胎发育表观遗传修饰的理解。
Evolution under Spatially Heterogeneous Selection in Solid Tumors
Guanghao Li#, Zuyu Yang#, Dafei Wu,Sixue Liu, Xuening Li, Tao Li, Yawei Li, Liji Liang, Weilong Zou, Chung-I Wu, Hurng-Yi Wang*, Xuemei Lu*
Key words
cancer evolution, tumor spatial growth model, intra-tumoral heterogeneity, natural selection, phenotypic diversity.
结构化种群的进化驱动力和动态进程及其预测:检测结构化群体进化过程中的自然选择颇具挑战性,不同阶段起主导作用的驱动力有所不同。我们引入中性空间模型,揭示了中性进化和自然选择的交替作用,驱动了肿瘤内遗传结构、克隆多样性的形成以及肿瘤的克隆扩张和取代。
