Abstract
Capsaicin (trans-8-methyl-n-vanillyl-6-nonenamide) is the main pungent component found in hot peppers.
AIM
In this study, we investigated the effect of capsaicin treatment on tumor growth and the metabolic indicators of cachexia in Walker 256 tumor-bearing rats.
METHODS
Male Wistar rats were inoculated subcutaneously in the right flank with 1 ml of a sterile suspension of 3 × 107 Walker tumor cells. The treated groups received capsaicin intraperitoneal 5 mg/kg body weight for 13 days.
RESULTS
The tumor weight on Day 14 in the non-treated group was 18 g. The rats also had a body weight loss, hypoglycemia, hyperlactacidemia, hypertriacylglycerolemia, and a depletion in glycogen storage. Treatment with capsaicin decreased tumor growth by 49% and a reversal of triacylglycerol serum. We also found a 32% reduction in tumor cell proliferation ex vivo. Lactate serum concentrations and body weight were lower but did not reach control levels.
CONCLUSION
The treatment with capsaicin reduces tumor growth and cellular proliferation along with increased apoptosis and partial cachexia reversal.
