Semaglutide targets mitochondria to regulate metabolism and inflammation in sarcopenia and osteoarthritis

ABSTRACT: Metabolic and inflammatory diseases often coexist, and become important challenges facing global health. As a traditional anti-obesity drug, semaglutide is reported to have therapeutic effects in sarcopenia and osteoarthritis (OA), but its mechanism of action still needs to be explored. Here we employed single-cell sequencing analysis to analyze transcriptome changes cross various tissues of high-fat diet (HFD) and OA model mice, and found that semaglutide significantly improved the metabolic and inflammatory disorders of muscle tissue during HFD and OA. Mechanistically, we found that semaglutide could enhance muscle mitochondrial metabolism and mitophagy, alleviated the activation of inflammatory cytokines caused by hypoxia, and regulated the progression of sarcopenia and OA across tissues. Intramuscular injection of mitochondria, pre-stimulated by semaglutide, could significantly alleviate OA inflammation and pain symptoms. These findings reveal the mitochondrial regulatory mechanism in the muscle-OA axis and provide a new perspective for the application of semaglutide in OA treatment.

Proteomic analysis reveals insufficient folliculogenesis in Aging Female associates with infertility

Project description:The escalating issue of infertility has become a global concern. Female infertility is primarily attributed to the decrease in both the quantity and quality of oocytes with advancing age, which is a significant factor in female infertility. The present study aims to explore the proteomic profile of exosomes obtained from human follicular fluid to identify the protein signature associated with aging and unsuccessful in vitro fertilization (IVF) outcomes. Despite the lack of significant differences in the morphology and particle size of follicular fluid exosomes between the two groups, the proteomic analysis demonstrated a distinct pattern of differentially expressed proteins. B cell activation, pathogen invasion, and disrupted metabolic processes were found to be significantly higher in the aging group, indicating the involvement of these pathways in aging-associated infertility. Moreover, the PI3K-AKT signaling pathway, which is linked to follicle maturation, was identified as the most influential signaling pathway in the aging group. In vivo experiments corroborated the weakened role of exosomes derived from the aging group in follicle maturation. Finally, the study employed a random forest machine learning algorithm, which further suggested that hydrolase activity might play a crucial role in determining the final IVF outcome. The expression of key differentially expressed proteins was validated. This study provides novel insights into the aging-associated protein signature of follicular fluid exosomes and their potential role in infertility. The findings imply that the aging-related protein signature in exosomes could serve to improve the diagnosis and treatment of infertility.

Proteomic Profiling of Rabbit Kidney Cells Infected with Equine Herpesvirus 8

Project description:Equine herpesvirus type 8 (EHV-8), a member of the alpha herpesvirus subfamily, is a significant pathogen in donkeys, causing abortion and respiratory infections, which result in considerable economic losses within the equine industry. Despite its importance, limited research has been conducted on the molecular response to EHV-8 in donkeys. The present study investigated the host cell response to EHV-8 infection in Rabbit kidney (RK-13) cells through transcriptomic and proteomic approaches. Our findings identified several candidate genes and proteins, along with their associated signaling pathways, involved in the cellular response to EHV-8 infection in this in vitro model. However, because RK-13 cells may not accurately replicate viral-host interactions in equine species, additional in vivo studies in horses and donkeys are necessary to achieve a more thorough understanding of viral pathogenesis in these animals.

Comparative analysis of serum proteins between hepatitis B virus genotype B and C infection DIA-based quantitative proteomics

Project description:Hepatitis B virus (HBV) is an enveloped, coated, non-cytopathic and hepatotropic partially double-stranded DNA virus in the family Hepadnaviridae genus Orthohepadnavirus. Despite significant progress in the availability of safe vaccines and antiviral therapies against HBV, it still affects approximately 257 million people worldwide and is responsible for about 887,000 deaths per year around the world [4]. HBV infection, which are associated with acute and chronic liver failure responses to viruses attacked the liver, can result in inactive carrier state, chronic hepatitis, or fulminant hepatitis and put them at high risk to develop advanced liver fibrosis and cirrhosis, and even hepatocellular cancer. Many viral factors, which could affect the disparity of clinical outcomes or disease prognosis during chronic HBV infection, have been reported in previous studies; among them, the viral genotype, as well as HBV mutations ascribing the virus to a certain phenotype, was reported to be the most important factor influencing viral pathogenesis, including the change of host immune recognition, the enhanced virulence with increased HBV replication and the facilitation of cell attachment or penetration.

Serum proteomic profiling in patients with advanced Schistosoma japonicum-induced hepatic fibrosis

Project description:Background: Schistosoma japonicum (S. japonicum) is a parasitic flatworm that is the aetiological agent of human schistosomiasis, an important cause of hepatic fibrosis. Schistosomiasis-induced hepatic fibrosis is a consequence of the highly fibrogenic nature of egg-induced granulomatuous lesions, the main pathogenic factor of schistosomiasis. Although global awareness of the association between schistosomiasis-indued hepatic fibrosis and s. japonicum infection is increasing, little is known about the molecular differences associated with rapid progression to schistosomiasis in cirrhotic patients. Methods: We systematically used data-independent acquisition (DIA)-based liquid chromatography-mass spectrometry to identify differentially expressed proteins in serum samples from patients with advanced S. japonicum-induced hepatic fibrosis. Results: On the basis of our analysis, we identified 1,144 proteins, among which 66 were differentially expressed between the healthy control and SHF-F2 groups and 214 were differentially expressed between the SHF-F2 and SHF-F4 groups (up- or downregulation of at least 1.5-fold in serum samples). Furthermore, our results indicated that two selected proteins (C1QA and CFD) are potential biomarkers for distinguishing patients with SHF-F2 and SHF-F4 resulting from S. japonicum infection. Conclusions: This report is the first to provide a global proteomic profile of serum samples from patients with advanced S. japonicum-induced hepatic fibrosis. C1QA and CFD are potentially diagnostic markers for patients with SHF-F2 and SHF-F4 resulting from S. japonicum infection, although further large-scale studies are needed. Our DIA-based quantitative proteomic analysis revealed molecular differences among individuals with different stages of advanced S. japonicum-induced hepatic fibrosis and might provide fundamental information for further detailed investigations.

A novel microprotein HDSP encoded by HOXA10-HOXA9 triggers progression of gastric cancer through maintaining the stability of MECOM and activating SPINK1-EGFR signaling

Project description:The abundance of noncanonical open reading frames present in long noncoding RNAs (lncRNAs) indicates the potential for translational capacity, thereby enabling the generation of multiple functional peptides or proteins. Nevertheless, the existence of peptide or protein products derived from lncRNAs and their specific roles in gastric cancer remain largely unexplored. In this study, we identified HOXA10-HOXA9-derived small protein (HDSP) in gastric cancer by conducting a comprehensive analysis and experimental validation with mass spectrometry and western blotting. HDSP is highly expressed and has oncogenic roles in gastric cancer. Mechanistically, HDSP blocked TRIM25-mediated ubiquitination and degradation by interacting with MECOM. This led to the accumulation of MECOM, which further enhanced the transcription of SPINK1, a gene that promotes cancer through the EGFR signaling pathway. In addition, MECOM promoted the transcription of HOXA10-HOXA9, creating a feedback regulatory loop that activated downstream SPINK1-EGFR signaling. Finally, we found that HDSP knockdown inhibited tumor growth in a patient-derived xenograft (PDX) model, and the infusion of an artificially synthesized HDSP peptide as a neoantigen improved the anti-tumor efficacy of immune cells against gastric cancer in vitro and in vivo. Our findings provide a potential therapeutic target or neoantigen candidate for the treatment of gastric cancer.

Analysis of the inflammatory transcription profiles of WT and Bid microglia

Project description:Apoptosis is a controlled cell-death process mediated inter alia by proteins of the Bcl-2 family. Some proteins previously shown to promote the apoptotic process were found to have non-apoptotic functions as well. Microglia, the resident immune cells of the central nervous system, respond to brain derangements by becoming activated to contend with the brain damage. Activated microglia can also undergo activation-induced cell death. Previous studies have addressed the role of core apoptotic proteins in the death process, but whether or not these proteins also play a role in the activation process has not been reported. Here we explore the effect of the BH3-only protein Bid on the immunological features of microglia by subjecting both WT and Bid deficient primary neonatal microglial cultures to LPS treatment (100 ng/ml, 3h) or left untreated (control) and analyzing their transcription profiles in order to study the role of Bid. 4 samples were analyzed. no replication.

Dominant Th2 differentiation of human regulatory T cells upon loss of FOXP3 expression

Project description:CD4+CD25+FOXP3+ regulatory T cells (Treg) are pivotal for peripheral self-tolerance. They prevent immune responses to auto- and alloantigens and are thus under close scrutiny as cellular therapeutics for autoimmune diseases and the prevention or treatment of alloresponses after organ or stem cell transplantation. We previously showed that human Treg cells with a memory cell phenotype, but not those with a naïve phenotype, rapidly down-regulate expression of the lineage-defining transcription factor forkhead box P3 (FOXP3) upon in vitro expansion. We now compared the transcriptomes of stable FOXP3+ Treg and converted FOXP3- 'ex-Treg' cells by applying a newly developed intranuclear staining protocol that permits the isolation of intact mRNA from fixed, permeabilized and FACS-purified cell populations. Whole genome microarray analysis revealed strong and selective upregulation of Th2 signature genes, including GATA-3, IL-4, IL-5 and IL-13, upon downregulation of FOXP3. Th2 differentiation of converted, FOXP3- ex-Treg cells occurred even under non-polarizing conditions and could not be prevented by IL-4 signaling blockade. Thus, our studies identify Th2 differentiation as the default developmental program of human Treg cells after downregulation of FOXP3. RNA preparations from FOXP3 stained in vitro expanded CD4+CD25highCD45RA- “memory” Treg cells from five independent donors were analyzed using Whole Human Genome Oligo Microarrays (Agilent). An adapted FOXP3 staining procedure to stain FOXP3 in human regulatory T cells to isolate intact RNA for microarray hybridization was developed (see extract protocol).
