During the 1800’s cannabis use was described as a treatment for a variety of metabolic disorders but its recreational use in the twentieth century resulted in laws which made the usage of cannabis illegal despite its medicinal properties. Cannabis usage has been reported to be useful in the treatment of Type 2 diabetes but unfortunately conflicting results are often published and its mechanism of action is still unknown. The aim of this project was to investigate the effect of phytocannabinoid treatment on adipogenesis and lipolysis in 3T3-L1 cells, to unravel their mechanism of action and also to test for potential anti-diabetic properties. The studies showed that phytocannabinoid treatment promoted higher glucose uptake and significantly less fat accumulation when compared to Rosiglitazone. Rosiglitazone is an anti-diabetic drug that has recently been withdrawn from the market since its usage has been associated with severe side effects.

Rosiglitazone is an anti-diabetic drug that has recently been withdrawn from the market since its usage has been associated with severe side effects. It was also found that phytocannabinoid treatment was able to reverse the insulin-resistant state of 3T3-L1 cells. The study indicates that the mechanism of action occurs at the mitochondrial level where enzymes such as succinate dehydrogenase and glycerol-3-phosphate dehydrogenase are modulated thereby affecting oxidative phosphorylation involved in the respiratory chain. In addition the effect observed with phytocannabinoid treatment is time dependent and affects the cells differently at different developmental stages. Therefore it can be concluded that phytocannabinoid treatment not only helps to maintain the balance between adipogenesis and lipolysis in 3T3-L1 cells but its use may also be helpful in the treatment of Type 2 diabetes and/or obesity-related insulin resistance.phytocannabinoid treatment was able to reverse the insulin-resistant state of 3T3-L1 cells.
