| 1 | Role and mechanism of action of leucine-rich repeat kinase 1 in bone显示文摘Leucine-rich repeat kinase 1 (LRRK1) plays a critical role in regulating cytoskeletal organization, osteoclast activity, and bone resorption with little effect on bone formation parameters. Deficiency of Lrrk1 in mice causes a severe osteopetrosis in the metaphysis of the long bones and vertebrae bones, which makes LRRK1 an attractive alternative drug target for the treatment of osteoporosis and other high-turnover bone diseases.This review summarizes recent advances on the functions of the Lrrk1-related family members, Lrrk1deficiency-induced skeletal phenotypes, LRRK1 structure–function, potential biological substrates and interacting proteins, and the mechanisms of LRRK1 action in osteoclasts. | Weirong Xing Helen Goodluck Canjun Zeng Subburaman Mohan | 2017 | Bone Research2017，5，1： | 2 |
| 2 | AKG/OXGR1 promotes skeletal muscle blood flow and metabolism by relaxing vascular smooth muscle显示文摘In response to contraction during exercise,skeletal muscle growth and metabolism are dynamically regulated by nerve action,blood flow,and metabolic feedback.α-Ketoglutarate(AKG),a bioactive intermediate in the tricarboxylic acid cycle released during exercise,has been shown to promote skeletal muscle hypertrophy.However,the underlying mechanism of AKG in regulating skeletal muscle development and metabolism is still less known.2-Oxoglutarate receptor 1(OXGR1),the endogenous AKG receptor,is found to be distributed in the vascular smooth muscle(VSM)of skeletal muscles.OXGR1 knockout results in skeletal muscle atrophy,accompanied by decreased expression of myosin heavy chain I(MyHC I),capillary density,and endurance exercise capacity.Furthermore,the study found that dietary AKG supplementation increased mice endurance exercise distance,MyHC I/MyHC IIb ratio,arteriole,and capillary densities in skeletal muscle.Meanwhile,acute AKG administration gradually increased the blood flow in the lower limbs.Further,by using OXGR1 global knockout and OXGR1 VSM-specific(MYH11-Cre×OXGR1-FloxP)knockdown models,we found that OXGR1 in VSM is essential for AKG-induced improvement of skeletal muscle performances.According to the in vitro study,AKG expanded the cell area in VSM with a decreased intracellular pH by OXGR1.Our results demonstrated a novel role of AKG/OXGR1 in VSM of skeletal muscle to regulate blood flow and then enhance slow muscle fiber conversion and capillarization.These findings provide a theoretical basis for the AKG/OXGR1 signaling pathway to maintain human muscle function and improve meat production and livestock and poultry meat quality. | Jinping Yang Guli Xu Yiming Xu Pei Luo Yexian Yuan Lin Yao Jingjing Zhou Yunlong Zhu Ishwari Gyawali Chang Xu Jinlong Feng Zewei Ma Yuxian Zeng Songbo Wang Ping Gao Canjun Zhu Qingyan Jiang Gang Shu | 2022 | Life Metabolism2022，1，3： | 0 |
