研究领域(Research Area

我国肥胖问题日益严重,对国民健康影响重大。解决肥胖问题的关键在于研究脂代谢。由于脂类难以直接观察以及脂代谢的复杂性,对其研究很具挑战。本课题组利用受激拉曼散射(stimulated Raman scattering, SRS)显微镜捕捉脂类碳氢键的拉曼信号来对脂类进行非标记化学成像并定量,并以秀丽线虫为模型创新高效地研究脂代谢以及脂代谢与衰老的关系。这些保守机制的研究成果可以扩展到高等生物中,将有助于寻找控制肥胖的方法和药物。

Obesity has become a real threat in China, resulting serious health problems. Studying lipid metabolism holds the key to solve obesity threat. However, studying lipid is challenging due to its invisibility under regular optical microscopes and the complexity of its metabolism. Our group use stimulated Raman scattering (SRS) microscopy to label-free chemically image and quantify lipid molecules in vivo, by capturing Raman scattering signal of CH2 bonds in lipids. We take advantage of our home-built SRS system and together with C.elegans as a model to efficiently study lipid metabolism and its dynamic changes during aging. Our works will advance our understanding of conserved lipid metabolic regulations in higher organisms, and shed new light on the control and treatment of obesity.
