MetabolomicsBrown and beige adipose tissue regulate systemic metabolism through a metabolite interorgan signaling axis
Brown and beige adipose tissue are emerging as distinct endocrine organs. These tissues are functionally associated with skeletal muscle, adipose tissue metabolism and systemic energy expenditure, suggesting an interorgan signaling network. Using metabolomics, we identify 3-methyl-2-oxovaleric acid,...

MetabolomicsGut microbiota-bile acid crosstalk contributes to the rebound weight gain after calorie restriction in mice
Calorie restriction (CR) and fasting are common approaches to weight reduction, but the maintenance is difficult after resuming food consumption. Meanwhile, the gut microbiome associated with energy harvest alters dramatically in response to nutrient deprivation. Here, we reported that CR and high-f...

MetabolomicsCholesterol metabolism regulates cartilage metabolic-inflammatory crosstalk by triggering osteocyte mitochondria transfer as a therapeutic target for osteoarthritis
Osteoarthritis (OA) is considered as a metabolic related inflammatory disease in the joint affecting both cartilage and subchondral bone. Cholesterol metabolism has been implicated in the pathogenesis of OA, yet the underlying mechanism still remains elusive. Understanding the role of cholesterol me...

MetabolomicsMicrobial-derived 3-phenylpropionic acid orchestrates immune–progenitor cell crosstalk to promote beige adipogenesis and energy expenditure

Cold exposure induces beige adipogenesis in white adipose tissue (iWAT), enhancing thermogenesis and energy expenditure. While gut microbiota-derived metabolites are known to regulate host metabolism, their role in thermogenic adaptation remains poorly defined. Here, we identify Prevotella copri ...

MetabolomicsDecipher aging related skin microbiome and metabolites crosstalk from a chronologically matched cohort

Aging has shown close link to shifts in the skin microbiome in population cohort study. However, how variations in microbial communities relate to divergent skin aging within individuals of the same chronological ages remains unclear. In this study, we performed phenotypic, metabolomic and metage...

MetabolomicsHypothalamic SLC7A14 accounts for aging-reduced lipolysis in white adipose tissue

The central nervous system has been implicated in the age-induced reduction in adipose tissue lipolysis. SLC7A14 is a lysosomal membrane protein highly expressed in the brain. Herein, we investigated the possible role of hypothalamic SLC7A14 in the age-induced lipolysis reduction. In this study, ...

MetabolomicsMulti-omics analysis reveals microbiota-metabolite crosstalk in MASLD pathogenesis in a non-obese murine model

The rising global prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD), including its severe form metabolic dysfunction-associated steatohepatitis (MASH), underscores the urgency to elucidate its pathophysiology. To investigate key metabolic interactions central to MASLD...

MetabolomicsEnterohepatic Axis Reprogramming via S1PR2 Inhibition Activates Compensatory Microbiota-Bile Acid Crosstalk to Ameliorate Colitis

Studies have revealed that gut microbiota dysbiosis and bile acid metabolism play pivotal roles in the pathogenesis of inflammatory bowel disease, and there exists a reciprocal interaction between gut microbiota and bile acid metabolism. S1PR2, a G protein-coupled receptor, has been demonstrated...

MetabolomicsIncreased adipose tissue Fas alters gut microbiota to aggravate colitis in obesity— Adipose Fas aggravates colitis via gut microbiota in obesity
Obesity is increasingly recognized as a factor that may exacerbate inflammatory bowel disease (IBD), yet the underlying mechanisms remain poorly understood. This study investigates whether upregulated Fas (CD95) expression in adipose tissue contributes to obesity-associated aggravation of colitis, w...

ProteomicsLGR signaling mediates muscle-adipose tissue crosstalk and protects against diet-induced insulin resistance
Obesity impairs tissue insulin sensitivity and signaling, promoting type-2 diabetes. Although improving insulin signaling is key to reversing diabetes, the multi-organ mechanisms regulating this process are poorly defined. We screened the secretome and receptome in Drosophila to identify the hormona...
