Spillover of viruses from bats to other animals may be associated with increased contact between them, as well as increased shedding of viruses by bats. Here, we tested the prediction that little brown bats (Myotis lucifugus) co-infected with the M. lucifugus coronavirus (Myl-CoV) and with Pseudogymnoascus destructans (Pd), the fungus that causes bat white-nose syndrome (WNS), exhibit different disease severity, viral shedding and molecular responses than bats infected with only Myl-CoV or only P. destructans...

Cancer-associated cachexia (CAC) is a disorder characterized by unintended weight loss due to skeletal muscle wasting and adipose tissue loss. Although muscle atrophy in this condition has been well studied, the mechanisms underlying adipose tissue loss, which include browning, have not been investigated in detail. In this respect, though recent studies have shown that exosomes from cancer cells can promote lipolysis, the link between exosomes from cancer cells and CAC has not been clearly established. In this study, we investigate if exosomes from Lewis lung carcinoma (LLC) cells can induce lipolysis in vitro (in 3T3-L1 adipocytes) and in vivo (in LLC tumor-bearing mice)...

Browning of white adipose tissue is a novel mechanism to counteract obesity in view of its thermogenic activity. Activation of G-protein-coupled receptor 120 (GPR120) can promote the browning of white fat. 9-PAHSA, an endogenous mammalian lipid, which is acting as the ligand of GPR120 to enhance glucose uptake and exert anti-inflammatory effect. In the study, we would like to investigate the biological effects of 9-PAHSA on adipocyte browning. Here, we show that 9-PAHSA induces browning of 3T3-L1 adipocytes via enhanced expression of brown fat specific genes...

Dietary supplementation with melinjo (Gnetum gnemon L.) seed extract (MSE) has been proposed as an anti-obesity strategy. However, it remains unclear how MSE modulates energy balance. We tested the hypothesis that dietary MSE reduces energy intake and/or increases physical activity and metabolic thermogenesis in brown and white adipose tissue (BAT and WAT) in mice. Twenty-four C57BL/6 J mice were provided with normal diet, high-fat diet (HFD), or HFD with 1% MSE added, for 17 weeks. Food intake, spontaneous locomotor activity, hepatic triglyceride (TG) content, and blood parameters were examined...

Chronic low-grade inflammation is known to be linked to obesity, and to occur in the early stages of the disease. This mechanism is complex and involves numerous organs, cells, and cytokines. In this context, inflammation of white adipose tissue seems to play a key role in the development of obesity. Because of its properties, prostaglandin E2 (PGE2), an emblematic inflammatory mediator, has been proposed as an actor linking inflammation and obesity. Indeed, PGE2 is involved in mechanisms that are dysregulated in obesity such as lipolysis and adipogenesis...

Candied quince is one of the most popular processing products of Japanese quince ( Chaenomeles japonica ) in Latvia. During the storage of dehydrated fruit, the colour turns darker, thus negatively influence the overall quality and consumers' acceptability of the product. The aim of the present study was to evaluate the effectiveness of different anti-browning agents in combination with fruit blanching and soaking as a type of pre-treatment to preserve the colour of candied quince during 8-months storage. The fruit were harvested at various maturity stage (i...

Recruitment and activation of thermogenic adipocytes have received increasing attention as a strategy to improve systemic metabolic control. The analysis of brown and brite adipocytes is complicated by the complexity of adipose tissue biopsies. Here, we provide an in-depth analysis of pure brown, brite, and white adipocyte transcriptomes. By combining mouse and human transcriptome data, we identify a gene signature that can classify brown and white adipocytes in mice and men. Using a machine-learning-based cell deconvolution approach, we develop an algorithm proficient in calculating the brown adipocyte content in complex human and mouse biopsies...

AIMS/HYPOTHESIS: Pleiotrophin, a developmentally regulated and highly conserved cytokine, exerts different functions including regulation of cell growth and survival. Here, we hypothesise that this cytokine can play a regulatory role in glucose and lipid homeostasis. METHODS: To test this hypothesis, we performed a longitudinal study characterising the metabolic profile (circulating variables and tissue mRNA expression) of gene-targeted Ptn-deficient female mice and their corresponding wild-type counterparts at different ages from young adulthood (3 months) to older age (15 months)...

Severe sepsis and septic shock are the biggest cause of mortality in critically ill patients. Obesity today is one of the world's greatest health challenges. Little is known about the extent of involvement of the white adipose tissue (WAT) in sepsis and how it is being modified by obesity. We sought to explore the involvement of the WAT in sepsis. We hypothesize that sepsis induces browning of the WAT and that obesity alters the response of WAT to sepsis. Six-week-old C57BL/6 mice were randomized to a high-fat diet to induce obesity (obese group) or control diet (nonobese group)...

Adipose tissues, function as energy metabolism and endocrine organ, are closely associated with metabolic diseases such as obesity, insulin resistance and diabetes. Liver kinase B1 (Lkb1) and mechanistic target of rapamycin (mTOR) play crucial roles in regulating energy metabolism and cell growth in adipose tissue. Our recent study generated an adipocyte-specific Lkb1 and mTOR double knockout (DKO) mouse model and found that DKO of Lkb1 and mTOR caused reduction of brown adipose tissue (BAT) and inguinal white adipose tissue (iWAT) mass but increase of liver mass...

Synergistic fungal pretreatment involving white-rot and brown-rot fugal pretreatment has shown great potential for enhancing the yield of sugars from biomass time-effectively and environmentally benign. In this work, the effects of this integrated fungal pretreatment on lignin characteristics and thermal behavior of corncob were examined in the view of whole plant valorization. The results show that an efficient deconstruction of lignin was achieved by white-rot fungus, and subsequent brown-rot fungus promoted the preferential breakdown of guaiacyl units, further enhancing lignin extraction efficiency (62...

Adipose deposits influence the quality of ruminant carcasses, and in suckling lambs, internal types of adipose deposits represent a notable proportion of total fat. The aim of this study was to perform a comparative analysis of the perirenal fat transcriptomes of suckling lambs from two breeds with different growth and carcass characteristics. The perirenal fat tissue from 14 suckling lambs (Assaf, n = 8; Churra, n = 6) was used for the RNA-seq analysis. The functional enrichment analysis of the 670 highly expressed genes (>150 fragments per kilobase of exon per million fragments mapped) in the perirenal fat transcriptome of both breeds revealed that the majority of these genes were involved in energy processes...

INTRODUCTION: Leading cancer hospitals have increasingly shared their 'brand' with smaller hospitals through affiliations. Because each brand evokes a distinct reputation for the care provided, 'brand-sharing' has the potential to impact the public's ability to differentiate the safety and quality within hospital networks. The general public was surveyed to determine the perceived similarities and differences in the safety and quality of complex cancer surgery performed at top cancer hospitals and their smaller affiliate hospitals...

Lipocalin-2 (LCN2) has been previously characterized as an adipokine regulating thermogenic activation of brown adipose tissue and retinoic acid (RA)-induced thermogenesis in mice. The objective of this study was to explore the role and mechanism for LCN2 in the recruitment and retinoic acid-induced activation of brown-like or ‘beige’ adipocytes. We found LCN2 deficiency reduces key markers of thermogenesis including uncoupling protein-1 (UCP1) and peroxisome proliferator-activated receptor gamma coactivator 1α (PGC-1α) in inguinal white adipose tissue (iWAT) and inguinal adipocytes derived from Lcn2 −/− mice...
