Gossypol's effects on ingestive behaviour in mice: The first step in a systematic process to define gossypol's suitability for use in murine pest management

TL;DRAbstract

Gossypol, synthesised by the cotton plant, Gossypium, causes physiological and behavioural changes in mammals, suggesting it may be suitable for murine pest management. One of the most under-studied responses to gossypol, especially in the house mouse, Mus musculus, is its effect on ingestive behaviour, with some authors reporting anorexia and others observing no effect on energy metabolism. Importantly, there has been no systematic analysis of gossypol’s effect on food intake in mice. Therefore, the goal of this thesis was to provide the initial step in defining gossypol’s effect on feeding behaviour in mice by observing their responses after exposure to precise doses of gossypol delivered via injection. Mice underwent two injection intraperitoneal (IP) paradigms; acute and chronic (11 daily injections) exposures to 0 (vehicle), 10, 30, 100 and 300 mg/kg b.wt., and 0 (vehicle) and 100 mg/kg b.wt. respectively. The intakes of bland (chow) and palatable tastants were measured during the
