| 1 | PITPNC1 promotes the thermogenesis of brown adipose tissue under acute cold exposure显示文摘Brown adipose tissue (BAT) plays an essential role in non-shivering thermogenesis. The phosphatidylinositol transfer protein, cytoplasmic 1 (PITPNC1) is identified as a lipid transporter that reciprocally transfers phospholipids between intracellular membrane structures. However, the physiological significance of PITPNC1 and its regulatory mechanism remain unclear. Here, we demonstrate that PITPNC1 is a key player in thermogenesis of BAT. While Pitpnc1^(−/−) mice do not differ with wildtype mice in body weight and insulin sensitivity on either chow or high-fat diet, they develop hypothermia when subjected to acute cold exposure at 4℃. The Pitpnc1^(−/−) brown adipocytes exhibit defective β-oxidation and abnormal thermogenesis-related metabolism pathways in mitochondria. The deficiency of lipid mobilization in Pitpnc1^(−/−) brown adipocytes might be the result of excessive accumulation of phosphatidylcholine and a reduction of phosphatidic acid. Our findings have uncovered significant roles of PITPNC1 in mitochondrial phospholipid homeostasis and BAT thermogenesis. | Guoqing Tang Chengxin Ma Liangkui Li Shaoyan Zhang Fengsheng Li Jin Wu Yesheng Yin Qing Zhu Yan Liang Ru Wang He Huang Tong-Jin Zhao Hongyuan Yang Peng Li Feng-Jung Chen | 2022 | Science China(Life Sciences)2022，65，11： | 2 |
| 2 | Stable Thiophene-sulfur Covalent Organic Frameworks for Oxygen Reduction Reaction(ORR)显示文摘Exploring novel materials deriving from earth resources to substitute for platinum(Pt) electrocatalyst to promote oxygen reduction reaction(ORR) of fuel cell cathode is very important. Herein, we have exploited two crystallographic thiophene-sulfur covalent organic frameworks(COFs), termed JUC-607 and JUC-608, as electrocatalysts that exhibited good ORR performances. These thiophene-sulfur COFs exhibited high stability, and their functional groups acting as active centers in the ORR can be precisely determined. Notably, due to a larger aperture for mass transfer and electrons transport, JUC-608 displayed a growing electrochemical performance, leading to a better ORR activity. Thus, this study will provide a new strategy for designing heteroatom-based COF materials for high-performance electrochemical catalysis. | CHANG Shunkai LI Cuiyan LI Hui ZHU Liangkui FANG Qianrong | 2022 | Chemical Research in Chinese Universities2022，38，2： | 0 |
