Inhibiting obesity progression by inhibiting adipocyte differentiation with a pre-adipocyte autophagy inhibitor
InactiveUS20110244059A1Preventing and mitigating and and obesityPreventing and mitigating and weight gainBiocideNervous disorderDiseaseAutophagic death
The present invention relates to methods of mitigating, preventing or treating weight gain or obesity in patients by administering one or more autophagy inhibitors, thereby, preventing the differentiation process of pre-adipocyte cells into a mature adipocytes. Specifically, the present invention relates to the surprising discovery that autophagy is critical for the cellular remodeling required during pre-adipocyte differentiation into mature adipocyte. By targeting and inhibiting one or more mechanisms in autophagy, adipocyte maturation is also inhibited, thus, providing a novel a pathway to prevent, mitigate and / or treat weight gain, obesity and associated diseases, such as type II diabetes.

The invention discloses an autophagy monitoring method for fat cells. Due to the adoption of a special structure, mature fat cells are full of plenty of lipid droplets, so that organelle and nucleus are displaced towards the periphery, and a typical autophagosome is hard to be seen under an electron microscope. Proved by a plurality of experiments, the method disclosed by the invention finally and successfully observes autophagy structures in various autophagy stages in mature 3T3-L1 fat cells by continuously improving the experiment condition. Besides, mature fat has a characteristic of being not easy to be transfected, so common plasmid transfection is hard to play an expectant effect. Therefore, the method disclosed by the invention utilizes a GFP-LC3 lentivirus method to infect 3T3-L1 fat cells, and the infection efficiency is as high as 80% or greater by observation under a fluorescence microscope. At nutrition and hunger condition, by the method disclosed by the invention, GFP-LC3 point-like aggregation phenomenon is successfully observed.
