这篇讲什么
杜巴尔等人综述指出,性染色体并非仅通过性腺激素影响健康,XX与XY组合本身就会改变基因剂量、表观遗传编程、免疫信号与代谢,从而塑造男女的衰老与疾病轨迹。文章整合了X染色体失活逃逸、X染色体再激活、X染色体亲本来源、X偏斜以及Y染色体嵌合丢失等机制,并讨论了这些发现对生物标志物、诊断、治疗和临床试验设计的转化意义。
原文开头
Dena B. Dubal1,2*, Fabrisia Ambrosio3,4, Michael B. Stout5,6, Dan Theodorescu7,8* Sex differences have traditionally been attributed to gonadal hormones, but accumulating evidence shows that sex chromosomes exert distinct, cell-autonomous effects on health, aging, and disease. XX and XY complements alter gene dosage, epigenetic programming, immune signaling, metabolism, and cellular stress responses, which shape aging and disease trajectories in women and men. This review integrates mechanistic advances in sex chromosome biology—including escape from X chromosome inactivation, X reactivation, parent-of-X-origin, X-skew, X- and Y-linked gene functions, and Y loss—with aging, neurologic disease, immunity, cancer, and cardiometabolic disease. …
