Context-dependent transcriptional regulation by NFIA, a crucial regulator of brown adipocyte differentiation and function
Keyword
Summary
Brown adipocytes have been considered a potential target of obesity and diabetes therapy through “enhancing energy dissipation” not through "suppressing energy intake". I and colleagues previously identified a transcription factor NFIA as a crucial regulator of brown adipodcyte differentiation. We aim to elucidate transcriptional regulation of brown adipocyte function by NFIA toward development of novel therapeutics.

Message

I am very honored to receive the Inamori Foundation Research Grant. As a medical scientist, using adipocytes as a model system, I would pursue both mechanistic insights and clinical significance.

Outline of Research Achievements

We identified the transcription factor NFIA as a regulator of brown adipocyte differentiation and function, and demonstrated that NFIA improves obesity and diabetes by both promoting energy expenditure and suppressing chronic inflammation. In addition, using large-scale biobank data, we investigated gene–environment interactions between genetic risk for type 2 diabetes and physical activity in relation to cardiovascular disease incidence. Furthermore, we developed a machine learning model to predict insulin resistance using nine simple clinical parameters, and showed that insulin resistance is a risk factor not only for diabetes and cardiovascular disease but also for cancer.
