Abstract
Fat and sugar overconsumption is the cause of increasing worldwide incidence of gastrointestinal tract in inflammatory conditions. The intestinal pre-inflammatory alterations are partially reversible, simultaneously inhibiting the predisposition to colitis. Searching for an effective pharmacotherapy for treating inflammatory conditions in the intestine is essential. This study aimed to investigate the effect of cannabigerol (CBG) on the inflammation state in the colon tissue of rats subjected to high-caloric diet. The experiment was conducted on male Wistar rats subjected to a standard or a high-fat high-sucrose diets for six weeks. For the last 14 days, half of rats from both groups received intragastrically cannabigerol solution (30 mg/kg of body mass). The ratio of n-6/n-3 PUFA, the activity of n-6 and n-3 PUFA, and arachidonic acid (AA) content in selected lipid fractions were determined by gas-liquid chromatography. Immunoblotting examined the expression of proteins involved in inflammation development. ELISA kits measured the content of arachidonic acid derivatives. CBG treatment reduced the n-6/n-3 PUFA ratio in TAG fraction and increased the n-3 PUFA pathway activity in almost all lipid fractions. Cannabigerol supplementation decreased AA concentration in PL and TAG. CBG also caused diminishments in the expression of cPLA, COX-1, COX-2, and 12/15-LOX, which was indirectly correlated with a decreased LTB4 level and an increased LXA4 level. We concluded that cannabigerol has a protective influence on the development of inflammation in the colon tissue under lipid and sugar overload condition, thereby favoring cancer initiation and progression.
