The investigation of the effects of topiramate on the hypothalamic levels of fat mass/obesity-associated protein and neuropeptide Y in obese female rats

Objective: The aim of the present study is to investigate the effects of topiramate on the fat mass/obesity-associated protein (FTO) and on the neuropeptide Y (NPY) level in the hypothalamus depending on the recently increased prevalence of obesity.

Method: In this study, twenty-four female rats were divided into four equal groups: Non-obese control, obese control, non-obese topiramate, and obese topiramate. Obese groups were fed with a 40% high-fat diet. At the end of the 9th week, the drug treatment started and the subjects were treated with topiramate once a day for 6 weeks. All animals underwent cardiac perfusion under high-dose anesthesia on the 15th week. Tissues were analyzed using biochemical, histological, and stereological methods.

Results: In terms of neuron number in the arcuate nucleus area, a significant difference was observed among all groups (P?P?P?

Discussion: In conclusion, the mechanism of the effect of topiramate to create a state of obesity is thought to involve the decrease in the levels of NPY and FTO.
