酒精介导的癌症占癌症相关死亡的 3.5% 以上，但酒精如何促进癌症仍然是一个重大的悬而未决的问题。利用果蝇，我们发现了膳食乙醇与河马途径肿瘤抑制成分丧失之间的新相互作用。 Hippo 通路通过灭活转录共激活因子 Yorkie 来抑制果蝇和哺乳动物的肿瘤，与 Hippo 信号传导受损相关的癌症谱与与酒精相关的癌症谱惊人地重叠。因此，我们的研究结果可能表明酒精介导的癌症中河马通路肿瘤抑制的丧失。乙醇会因扩张型、河马型或疣型肿瘤抑制因子的丧失而促进过度生长，但令人惊讶的是，乙醇却不会因约克癌癌基因的过度表达而促进过度生长。我们认为，与约克夏依赖性过度生长同时，在酒精存在下损害河马信号可能会通过额外的酒精相关目标促进过度生长。我们还发现了酒精和河马通路过度激活之间的相互作用。我们认为，超过一定的酒精暴露阈值会激活 Hippo 信号传导，以维持适当的生长控制并防止酒精介导的错误模式和组织过度生长。
Alcohol-mediated cancers represent more than 3.5% of cancer-related deaths, yet how alcohol promotes cancer is a major open question. Using Drosophila, we identified novel interactions between dietary ethanol and loss of tumor suppressor components of the Hippo Pathway. The Hippo Pathway suppresses tumors in flies and mammals by inactivating transcriptional co-activator Yorkie, and the spectrum of cancers associated with impaired Hippo signaling overlaps strikingly with those associated with alcohol. Therefore, our findings may implicate loss of Hippo Pathway tumor suppression in alcohol-mediated cancers. Ethanol enhanced overgrowth from loss of the expanded, hippo, or warts tumor suppressors but, surprisingly, not from over-expressing the yorkie oncogene. We propose that in parallel to Yorkie-dependent overgrowth, impairing Hippo signaling in the presence of alcohol may promote overgrowth via additional alcohol-relevant targets. We also identified interactions between alcohol and Hippo Pathway over-activation. We propose that exceeding certain thresholds of alcohol exposure activates Hippo signaling to maintain proper growth control and prevent alcohol-mediated mis-patterning and tissue overgrowth.
