Nature Aging：奶茶等高果糖饮食，会促进肿瘤转移扩散

TL;DR - A Nature Aging paper (Wistar Institute / Univ. of Pittsburgh, published 2026-07-30) reports that the chemotherapy-induced senescence-associated secretory phenotype (SASP) drives ovarian cancer cell detachment and metastatic dissemination via metabolic reprogramming, with dietary fructose amplifying the effect. Note: this item is biomedical research with no AI/ML component, despite the digest's AI focus.

• Cisplatin-induced therapy-induced senescence (TIS) in high-grade serous ovarian cancer (HGSOC) produces a SASP that, acting in a paracrine manner on non-senescent bystander cells, increases cell detachment in vitro and peritoneal dissemination in vivo.
• Fructose was identified as a metabolite component of the SASP that promotes detachment; a high-fructose diet (the sweetener context cited is high-fructose corn syrup in drinks/ultra-processed foods) increased HGSOC dissemination in animal models.
• Mechanistically, mitochondrial complex I is the key driver: SASP-mediated suppression of the NAD+–SIRT–SREBP axis lowers plasma-membrane cholesterol, easing cell detachment from the primary tumor.
• Clinical framing: ~90% of HGSOC deaths involve recurrence and all recurrent cases show disseminated lesions, so a pro-metastatic SASP could help explain platinum-therapy relapse rates. Paper: https://www.nature.com/articles/s43587-026-01172-5
