Enteric glial cells (EGCs) are the main constituent of enteric nervous system and share similarities with astrocytes from central including their reactivity to an inflammatory microenvironment. Previous studies on EGC pathophysiology have specifically focused mucosal glia activation its contribution processes observed in gut bowel disease (IBD) patients. In contrast knowledge is scarce intestinal inflammation not locally restricted mucosa but systemically affecting intestine effect overall...

Glycolysis and fatty acid synthesis are highly active in cancer cells through cytosolic citrate metabolism, with intracellular primarily derived from either glucose or glutamine via the tricarboxylic cycle. We show here that extracellular is supplied to a plasma membrane-specific variant of mitochondrial transporter (pmCiC). Metabolomic analysis revealed uptake broadly affected cell metabolism citrate-dependent metabolic pathways. Treatment gluconate specifically blocked pmCiC decreased...

Inhibition of histone deacetylase 6 (HDAC6) is predicted to deliver both direct antitumor activity and modulation the immune response. This study describes development a novel HDAC6 inhibitor.KA2507 was characterized in HDAC biochemical cellular target engagement assays preclinical efficacy models melanoma colorectal cancer. In phase I study, KA2507 administered orally using 3+3 dose-escalation design (NCT03008018).KA2507 potent selective inhibitor (biochemical IC50 = 2.5 nmol/L)....

The FK228 and spiruchostatin bicyclic depsipeptide natural products are among the most potent histone deacetylase (HDAC) inhibitors known. Although is in advanced clinical trials, complexity of has precluded mechanistic studies discovery structure−activity relationships. By total synthesis, we have prepared first analogues. Our results prove that dehydrobutyrine residue not essential, other residues can be substituted without loss HDAC inhibitory activity. Conformational restriction by...

Abstract Metabolomic analyses in epidemiological studies have demonstrated a strong sexual dimorphism for most metabolites. Cross-sex hormone treatment (CSH) transgender individuals enables the study of metabolites cross-gender setting. Targeted metabolomic profiling serum fasting transmen and transwomen at baseline following 12 months CSH (N = 20/group) was performed. Changes 186 metabolite ratios were determined by targeted metabolomics analysis based on ESI-LC-MS/MS. RandomForest (RF)...

Citrate is important for lipid synthesis and epigenetic regulation in addition to ATP production. We have previously reported that cancer cells import extracellular citrate via the pmCiC transporter support their metabolism. Here, we show first time supplied by cancer-associated stroma (CAS) also release one of latter’s major metabolic tasks. from CAS controlled through cross-cellular communication. The availability regulated cytokine profile, metabolism features cellular invasion. Moreover,...

Virotherapy on the basis of oncolytic vaccinia virus (VACV) strains is a novel approach for canine cancer therapy. Here we describe, first time, characterization and use VACV strain GLV-5b451 expressing anti-vascular endothelial growth factor (VEGF) single-chain antibody (scAb) GLAF-2 as therapeutic agent against different cancers. Cell culture data demonstrated that efficiently infected destroyed all four tested cell lines including: mammary carcinoma (MTH52c), adenoma (ZMTH3), prostate...

This study compared metabolite shifts induced by training for, participation in, and recovery from a marathon race competition among athletes divided into three groups based on fitness (relative maximum oxygen uptake (VO2max)) performance levels (net running time). Plasma samples 76 male runners participating in the Munich Marathon were analyzed for using targeted metabolomics panel. For entire cohort of runners, pronounced increases measured immediately after plasma concentrations...

Background Sex hormones and sex hormone-binding globulin (SHBG) may play a role in fatty liver development. We sought to examine the association of various endogenous hormones, including testosterone (T), SHBG with fat using complementary observational Mendelian randomization (MR) analyses. Methods The analysis included total 2,239 participants (mean age 60 years; 35% postmenopausal women) from population-based KORA study (average follow-up time: 6.5 years). conducted linear regression...
