MetabolomicsBone loss with aging is independent of gut microbiome in mice.

Emerging evidence suggests a significant role of gut microbiome in bone health. Aging is well recognized as a crucial factor influencing the gut microbiome. In this study, we investigated whether age-dependent microbial change contributes to age-related bone loss in CB6F1 mice. The bone phenotype...

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...

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...

MetabolomicsAlcohol-Induced Bone Loss: Driven by Dysregulated Spatial Distribution of Gut Microbiota and PGD2-IL17 Pathway-Mediated Osteoclast Activation

Purpose: Alcohol-induced damage to bone microstructure leads to alcoholic osteopenia (AOP). While prior studies have demonstrated alcohol's negative impact on bone density, the mechanisms by which alcohol induces osteoporosis through immune pathways, gut microbiota dysbiosis, and metabolic altera...

MetabolomicsPla2g7 regulates bone homeostasis via Alox12/12-HETE/Gpr31 signaling axis

Bone homeostasis mainly depends on the equilibrium of osteoclasts and osteoblasts, overactivated osteoclasts play a pivotal role in the progression of osteoporosis. Here, we revealed that Pla2g7 (phospholipase A2 group VII) was positively correlated with bone resorption in clinic. By single-cell ...

MetabolomicsIntestinal accumulation of microbiota-produced succinate caused by loss of microRNAs leads to diarrhea in weanling piglets
Diarrheal disease is a common health problem with complex causality. Although diarrhea is accompanied by disturbances in microbial diversity, how gut microbes are involved in the occurrence of diarrhea remains largely unknown. Here, using a pig model of post-weaning stress-induced diarrhea, we aim t...

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...

ProteomicsREGγ is essential to maintain bone homeostasis by degrading TRAF6, preventing osteoporosis
Primary osteoporosis, manifesting as decreased bone mass and increased bone fragility, is a “silent disease” that is often ignored until a bone breaks. Accordingly, it is urgent to develop reliable biomarkers and novel therapeutic strategies for osteoporosis treatment. Here, we identified REGγ as...

ProteomicsELMO1 signaling is a promoter of osteoclast function and bone loss
Osteoporosis and bone fractures affect millions of men and women worldwide and are often due to increased bone resorption (bone loss) mediated by osteoclasts. Here, we identify a novel role for the cytoplasmic protein ELMO1 as an important ‘signaling node’ controlling the bone resorption function of...

TranscriptomicsT cell acute leukaemia development and chemo-resistance are mediated by dynamic interactions with heterogeneous bone marrow microenvironments.
It is widely accepted that complex interactions between cancer cells and their surrounding microenvironment contribute to disease development, chemo-resistance and disease relapse. In light of this observed interdependency, novel therapeutic interventions that target specific cancer stroma cell line...
