MetabolomicsButyrate deficiency due to microbial dysbiosis promotes anxiety

for this association remains incompletely understood. Diabetes-associated genes have been implicated in the control of central nervous system (CNS) disorders. In the current study, we observed a significant downregulation of secretagogin (SCGN) across multiple organs in diabetic mouse models. Con...

MetabolomicsDefective mitochondrial COX1 translation due to loss of COX14 function triggers ROS-induced inflammation in liver
Mitochondrial oxidative phosphorylation (OXPHOS) fuels cellular ATP demands. OXPHOS defects lead to severe human disorders with unexplained tissue specific pathologies. Mitochondrial gene expression is essential for OXPHOS biogenesis since core subunits of the complexes are mitochondrial-encoded. CO...

MetabolomicsGlobal Analyses of Selective Insulin Resistance in Hepatocytes due to Palmitate Lipotoxicity
Obesity is tightly linked to hepatic steatosis and insulin resistance. One feature of this association is the paradox of selective insulin resistance: insulin fails to suppress hepatic gluconeogenesis but activates lipid synthesis in the liver. How lipid accumulation interferes selectively with some...

MetabolomicsNeuronal Hyperactivity due to Loss of Inhibitory Tone in APOE4 Mice Lacking Alzheimer’s Disease-like Pathology
Metabolite profiling was performed on metabolites extracted from the entorhinal cortex and primary visual cortex of 14-15 month old APOE3/3, APOE3/4 and APOE4/4 mice. Metabolites were run on a TOF Mass Spectrometer using an ANP column. Initial analysis was done in an untargeted manner, and processin...

TranscriptomicsIdentification of IL-21-induced STAT3 dependent genes in human B cells
IL-21 induces B cell activation, and differentiation into antibody-secreting plasmablasts in vitro. This process is abolished by loss-of function mutations in STAT3 We used microarrays to identify genes that are induced by IL-21 in a STAT3-dependent manner Sort-purified naïve B cells from four heal...

Transcriptomicssingle cell RNAseq of memory B cells in the context of rituximab-treated ITP patients
Rituximab (RTX) is widely used as a first-line therapeutic strategy in B cell-mediated autoimmune diseases. However, a large proportion of patients either do not respond to the treatment or relapse during B cell reconstitution. Primary immune thrombocytopenia (ITP) is a prototypic B cell mediated au...

TranscriptomicsGene expression of murine B cells activated via TLR4 or TLR4 + CD40: Group1 naM-CM-/ve B cells, Group2 LPS activated B cells 24h, Group3 LPS + anti-CD40 activated B cells 24h, Group4 LPS activated B cells 72h, and Group5 LPS + anti-CD40 activated B cells 72h.
Murine B cells can be activated via the surface receptors TLR4 and CD40. For a global assessment of differences in gene expression between these two different modes of B cell activation a genome wide transcriptome analysis was performed. In order to dissect different gene expression profiles of B ce...

TranscriptomicsTranscription profiling of mature, naive B cells to investigate how the PTPN22 autoimmune susceptibility gene affects the removal of human developing autoreactive B cells.
Protein tyrosine phosphatase nonreceptor type 22 (PTPN22) gene segregates with most autoimmune diseases; its risk allele encodes overactive PTPN22 phosphatases that alter B cell receptor (BCR) signaling potentially involved in the regulation of central B cell tolerance. To assess whether PTPN22 ris...

GenomicsThe B cell identity factor Pax5 regulates distinct transcriptional programs in early and late B lymphopoiesis
Pax5 controls the identity and development of B cells by repressing lineage-inappropriate genes and activating B-cell-specific genes. Here, we used genome-wide approaches to identify Pax5 target genes in pro-B and mature B cells. In these cell types, Pax5 bound to 40% of the cis- regulatory elements...
