Here, we show that macrophages accumulate PR:PROJECT_SUMMARY within tumors of obese CRC patients and in obese CRC mice and promote PR:PROJECT_SUMMARY accelerated tumor growth. These changes are initiated by oleic acid accumulation PR:PROJECT_SUMMARY and subsequent tumor cell-derived acid production, and driven by signaling PR:PROJECT_SUMMARY through GPR65, an acid-sensing receptor on CRC-associated macrophages. We PR:PROJECT_SUMMARY demonstrate a similar role for GPR65 in hepatocellular carcinoma (HCC) in obese PR:PROJECT_SUMMARY mice. Tumors in obese patients with CRC or HCC also exhibit increased GPR65 PR:PROJECT_SUMMARY expression, suggesting that the mechanism revealed here likely contributes to PR:PROJECT_SUMMARY tumor growth in a range of obesity-associated cancers and represents a potential PR:PROJECT_SUMMARY therapeutic target.

ST:STUDY_SUMMARY Frozen human colorectal adenocarcinoma tumors samples were acquired and analyzed ST:STUDY_SUMMARY for fatty acid composition via GC-FID. These data revealed an increase in ST:STUDY_SUMMARY several fatty acids, such as palmitic acid, stearic acid, oleic acid, etc., in ST:STUDY_SUMMARY obese patients. However, oleic acid was the most abundant fatty acid in tumors ST:STUDY_SUMMARY of obese patients and also the fatty acid that exhibited the most significant ST:STUDY_SUMMARY increase in obese patients compared to normal-weight patients.
