表观遗传信息是如何代代相传的,这在很大程度上仍然是未知的。秀丽隐杆线虫组蛋白H3赖氨酸4二甲基(H3K4me2)去甲基化酶spr-5的缺失会导致H3K4me2标记的遗传积累和生育能力的逐渐下降。在这里,我们发现了多种染色质修饰因子,包括新的H3K4me1/me2和H3K9me3甲基转移酶,H3K9me3去甲基化酶和H3K9me读取器,它们抑制或加速了spr-5突变蠕虫的进行性跨代表型。我们的发现揭示了一个染色质调控网络,它控制着表观遗传信息的跨代流动,并表明正染色质H3K4和异染色质H3K9甲基化之间的平衡调节着跨代对生育的影响。
How epigenetic information is transmitted from generation to generation remains largely unknown. Deletion of the C. elegans Histone H3 lysine 4 dimethyl (H3K4me2) demethylase spr-5 leads to inherited accumulation of the euchromatic H3K4me2 mark and progressive decline in fertility. Here we identified multiple chromatin-modifying factors, including novel H3K4me1/me2 and H3K9me3 methyltransferases, an H3K9me3 demethylase and an H3K9me reader, which either suppress or accelerate the progressive transgenerational phenotypes of spr-5 mutant worms. Our findings uncover a network of chromatin regulators that control the trans-generational flow of epigenetic information, and suggest that the balance between euchromatic H3K4 and heterochromatic H3K9 methylation regulates trans-generational effects on fertility.
