MetabolomicsMechanical force promotes dimethylarginine dimethylaminohydrolase 1-mediated hydrolysis of the metabolite asymmetric dimethylarginine to enhance bone formation

Mechanical force is critical for the development and remodeling of bone. Here we report that mechanical force regulates the production of the metabolite asymmetric dimethylarginine (ADMA) via regulating the hydrolytic enzyme dimethylarginine dimethylaminohydrolase 1 (Ddah1) expression in osteobla...

MetabolomicsInhibiting glutaminase exerts opposite effects on ovariectomy-induced and age-related reductions in murine bone mass
Recent studies have provided links between glutamine metabolism and bone remodeling, but little is known about its role in primary osteoporosis progression. We aimed to determine the effects of inhibiting glutaminase (GLS) on two types of primary osteoporosis and elucidate the related metabolism. To...

ProteomicsPhlpp1 alters the murine chondrocyte phospho-proteome during endochondral bone formation
Appendicular skeletal growth and bone mass acquisition are controlled by a variety of growth factors, hormones, and mechanical forces in a dynamic process called endochondral ossification. In long bones, chondrocytes in the growth plate proliferate and undergo hypertrophy to drive bone lengthening a...

MetabolomicsHarnessing Exogenous Stimuli and Functionally 3D Aligned Fibrous Scaffolds for Spatiotemporal Modulation of Bone Regeneration

Bone regeneration requires spatiotemporal coordination of immune modulation, stem cell recruitment, angiogenesis, and osteogenesis, yet most scaffolds lack sequential control across healing phases. We develop a near-infrared (NIR)-responsive therapeutic platform that integrates clinically av...

MetabolomicsUridine Attenuates Osteoclastogenesis and Ovariectomy Induced Bone Loss by Modulating the PI3K/Akt–FoxO ROS Signaling Axis

Osteoporosis is a metabolic bone disorder characterized by aberrant osteoclast activation, leading 

to excessive bone resorption and microarchitectural deterioration. Although the interconnection 

between osteoclast differentiation and cellular energy metabolism has been inc...

TranscriptomicsDetermine the effects of Hdac3 deletion on H3K27ac profiles in murine chondrocytes[RNA-Seq]
Histone deacetylase inhibitors are efficacious epigenetic-based therapies for some cancers and neurological disorders; however, these drugs inhibit multiple Hdacs and have detrimental effects on the pre- and post-natal skeleton. To better understand how Hdac inhibitors affect the skeleton, we focus...

MetabolomicsPostoperative Exercise Modulating Gut Microbiota and Associated Metabolites to Facilitate Bone-Tendon Healing in Rotator Cuff Tears

Background: Rotator cuff tear (RCT) is a prevalent shoulder injury, and postoperative exercise is considered to facilitate RCT healing. However, the effect of postoperative exercise on RCT healing through gut microbiota and metabolites remains unclear.

Method: The control (con) group (n=10...
