Alteration of liver fat metabolism following irinotecan plus 5-fluorouracil treatment

  • This study determined how chemotherapy treatment for colorectal cancer alters hepatic fat metabolism. Livers were isolated from tumor-bearing animals after one and two cycles of chemotherapy consisting of irinotecan plus 5-fluorouracil. Fatty acid amounts and composition within triglycerides (TG) and phospholipids (PL) as well as gene expression were assessed. Total TG did not change and total PL were higher after 7 days following treatment. Docosahexaenoic acid became undetectable after the treatment at 5 and 7 days, respectively. Following one cycle, the alterations appeared temporary. After second cycle, total TG were lower and n-3 fatty acids were also lower causing n-6/n-3 ratio to be higher. Chemotherapy altered 13 genes of 44, however not all genes within a single pathway were affected. The alterations in gene expression did not necessarily parallel the observations in fatty acids. This study is important to develop identify target pathways to circumvent negative effects of chemotherapy-associated steatohepatitis.
