The Claim
In Drosophila with Ras/Src-induced tumors, knockdown of PEPCK1 reduces Wingless/Wnt and TOR signaling under high-sugar conditions, indicating that PEPCK1 acts upstream of these pathways to promote tumor progression.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In fruit flies with specific cancer-causing mutations, reducing the activity of the PEPCK1 gene lowers signaling through the Wingless/Wnt and TOR pathways when sugar levels are high, and this reduction is associated with decreased tumor growth.
See the scientific wording
In Drosophila with Ras/Src tumors, PEPCK1 knockdown reduces Wingless/Wnt and TOR signaling under high-sugar conditions, suggesting that PEPCK1 acts upstream of these key oncogenic pathways to promote tumor progression.
When sugar levels are high, a gene called PEPCK1 becomes overactive in tumor cells, which changes how the cells use energy. This change increases the production of certain molecules that turn on two key growth signals—Wingless and TOR. These signals make the tumor cells multiply faster, avoid death, and take up more sugar to fuel their growth. Turning off PEPCK1 stops this chain, slowing the tumor and making the cells more likely to die.
What the research says
1 studyStudy: High sugar diet promotes tumor progression paradoxically through aberrant upregulation of pepck1
In sugar-fed cancerous fruit flies, turning off the PEPCK1 gene made tumors smaller and the flies live longer because it turned down two key cancer growth signals—Wingless and TOR. This shows PEPCK1 helps turn on those signals to make cancer worse.
