Key Findings
- Kisspeptin-10 increased liver levels of glutathione (GSH), total antioxidant capacity (T‑AOC) and superoxide dismutase (SOD) activity.
- It reduced markers of oxidative damage (MDA) and improved liver tissue structure after heat stress.
- Metabonomic profiling indicated that kisspeptin-10 mainly corrected disturbances in purine and fatty‑acid metabolism caused by heat stress.
Practical Outcomes
- For biohackers, the data suggest kisspeptin‑10 might have antioxidant properties that could protect against acute stress‑related liver injury, but the evidence is limited to rats and a specific heat‑stress model. No human dosing, safety, or real‑world protocols are provided, so it’s not ready for direct use. It may be worth monitoring future human studies before considering supplementation.
Summary
In rats, giving kisspeptin-10 before a hot‑stress event helped protect the liver. The peptide reduced damage by boosting antioxidant defenses and normalising metabolism of purines and fats. The study shows a possible anti‑oxidant role for kisspeptin, but it’s an early animal experiment.
Abstract
The protective effects of Kisspeptin on heat-induced oxidative stress in rats were investigated by using a combination of biochemical parameters and metabonomics. Metabonomic analyses were performed using gas chromatography/mass spectrometry in conjunction with multivariate and univariate statistical analyses. At the end point of the heat stress experiment, histological observation, ultrastructural analysis and biochemical parameters were measured. Metabonomic analysis of liver tissue revealed that Kisspeptin mainly attenuated the alteration of purine metabolism and fatty acid metabolism pathways. Futhermore, Kisspeptin also increased the levels of GSH, T-AOC as well as SOD activities, and upregulated MDA levels. These results provide important mechanistic insights into the protective effects of Kisspeptin against heat-induced oxidative stress.
