Sex-specific biological aging clocks across organs and omics.
研究基于性別差異構建生物衰老時鐘。研究者開發了涵蓋15個器官系統的38個性別特異性生物衰老時鐘,先證明性別分層訓練對建立性別特異性健康常模參照的重要性,繼而揭示女性與男性時鐘之間的顯著差異。關鍵遺傳參數與孟德爾隨機化結果顯示,器官特異性衰老易感性及其與心代謝、內分泌和精神性狀的關係在男女中配置不同。蛋白質體分析識別出分別追蹤女性與男性生物衰老的器官特異性突觸、免疫、血管和代謝網絡。縱向生存分析中,性別特異性時鐘以性別依賴和器官依賴的方式預測全身系統性疾病和全因死亡率。進一步分析揭示,在臨床前阿茲海默症臨床試驗中,腦衰老時鐘與認知衰退軌跡之間存在性別依賴性關聯。性別分層時鐘以性別適宜的常模參照界定生物年齡,並揭示合併模型可能掩蓋的性別依賴性遺傳、分子和臨床特徵;同時,性別合併和性別交互方法仍有價值,因為人類衰老和疾病在男女之間也存在基本生物學相似性。這些發現揭示衰老、阿茲海默症和全身健康中的性別特異性生物衰老特徵,突顯明確性別分層建模方法的必要性。

为什么值得关注
编辑短评该研究针对现有衰老时钟按性别合并训练、默认性别不变的局限,构建了覆盖15个器官系统的38个性别特异性时钟,揭示男女在遗传、蛋白质组网络及疾病与死亡预测上的分化,并提示合并模型可能掩盖性别依赖信号。其价值在于为性别分层建模提供系统依据。
