As aging and tumorigenesis are tightly interconnected biological processes, targeting their common underlying driving pathways may induce dual-purpose anti-aging and anti-cancer effects. Our transcriptomic analyses of 16,740 healthy samples demonstrated tissue-specific age-associated gene expression, with most tumor suppressor genes downregulated during aging. Furthermore, a large-scale pan-cancer analysis of 11 solid tumor types (11,303 cases and 4431 control samples) revealed that many cellular processes, such as protein localization, DNA replication, DNA repair, cell cycle, and RNA metabolism, were upregulated in cancer but downregulated in healthy aging tissues, whereas pathways regulating cellular senescence were upregulated in both aging and cancer. Common cancer targets were identified by the AI-driven target discovery platform-PandaOmics. Age-associated cancer targets were selected and further classified into four groups based on their reported roles in lifespan. Among the 51 identified age-associated cancer targets with anti-aging experimental evidence, 22 were proposed as dual-purpose targets for anti-aging and anti-cancer treatment with the same therapeutic direction. Among age-associated cancer targets without known lifespan-regulating activity, 23 genes were selected based on predicted dual-purpose properties. Knockdown of histone demethylase KDM1A, one of these unexplored candidates, significantly extended lifespan in Caenorhabditis elegans. Given KDM1A's anti-cancer activities reported in both preclinical and clinical studies, our findings propose KDM1A as a promising dual-purpose target. This is the first study utilizing an innovative AI-driven approach to identify dual-purpose target candidates for anti-aging and anti-cancer treatment, supporting the value of AI-assisted target identification for drug discovery.
随着衰老和肿瘤发生是紧密相关的生物学过程,针对它们共同的潜在驱动途径可能会诱导双重抗衰老和抗癌作用。我们对 16740 个健康样本的转录组分析表明,组织具有特定的年龄相关基因表达,大多数肿瘤抑制基因在衰老过程中下调。此外,对 11 种实体瘤类型(11303 例病例和 4431 例对照样本)的大规模泛癌症分析显示,许多细胞过程,如蛋白质定位、DNA 复制、DNA 修复、细胞周期和 RNA 代谢,在癌症中上调,但在健康衰老组织中下调,而调节细胞衰老的途径在衰老和癌症中均上调。AI 驱动的靶点发现平台-PandaOmics 鉴定了共同的癌症靶点。选择与年龄相关的癌症靶点,并根据其在寿命中的报道作用进一步分为四组。在 51 个已确定的具有抗衰老实验证据的与年龄相关的癌症靶点中,有 22 个被提议作为抗衰老和抗癌治疗的双重用途靶点,具有相同的治疗方向。在没有已知寿命调节活性的与年龄相关的癌症靶点中,根据预测的双重用途特性选择了 23 个基因。其中一个未被探索的候选基因组蛋白去甲基化酶 KDM1A 的敲低显著延长了秀丽隐杆线虫的寿命。鉴于 KDM1A 在临床前和临床研究中均报道具有抗癌活性,我们的研究结果提出 KDM1A 是一个有前途的双重用途靶点。这是首次利用创新的 AI 驱动方法鉴定抗衰老和抗癌治疗的双重用途靶点候选物的研究,支持 AI 辅助靶点鉴定在药物发现中的价值。
