Differential DNA sequence specificity and regulation of HIV-1 enhancer activity by cRel-RelA transcription factor.

Journal of Biological Chemistry, 1994
The cRel-RelA and NF-kappa B (p50-RelA) transcription factors bind to a kappa B-like sequence termed Rel-related proteins binding element localized in the regulatory region of the human urokinase plasminogen activator (uPA) gene. This sequence is highly conserved in murine and porcine uPA genes where it retained the ability to associate with cRel-RelA.

Involvement of Egr-1/RelA Synergy in Distinguishing T Cell Activation from Tumor Necrosis Factor-α–induced NF-κB1 Transcription [PDF]

The Journal of Experimental Medicine, 1997
NF-κB is an important transcription factor required for T cell proliferation and other immunological functions. The NF-κB1 gene encodes a 105-kD protein that is the precursor of the p50 component of NF-κB. Previously, we and others have demonstrated that NF-κB regulates the NF-κB1 gene.

RIG‐I Mediated Neuron‐Specific IFN Type 1 Signaling in FUS‐ALS Induces Neurodegeneration and Offers New Biomarker‐Driven Individualized Treatment Options for (FUS‐)ALS

Advanced Science, EarlyView.
Using iPSC‐derived motoneurons and postmortem tissue from FUS‐ALS patients, it is demonstrated that increased mitochondrial transcription leads to elevated cytosolic double‐stranded RNA (dsRNA) levels. This aberrant accumulation activates a RIG‐I–dependent innate immune response leading to neurodegeneration, which is amenable for FDA‐ and EMA‐approved ...

Microglia Mitochondria Support Neuronal Maturation via Metabolic and Transcriptional Reprogramming in Human 3D In Vitro Brain Model

Advanced Science, EarlyView.
xx xx. ABSTRACT Autism Spectrum Disorder (ASD) is a neurodevelopmental condition characterized by disrupted neuronal circuit maturation. Emerging evidence implicates microglial function and mitochondrial regulation as contributors to ASD‐associated biology, yet the mechanisms linking these processes to neuronal development remain poorly defined ...

Genetic Predisposition to Chronic Lymphocytic Leukemia Is Mediated by a BMF Super-Enhancer Polymorphism

Cell Reports, 2016
Chronic lymphocytic leukemia (CLL) is an adult B cell malignancy. Genome-wide association studies show that variation at 15q15.1 influences CLL risk. We deciphered the causal variant at 15q15.1 and the mechanism by which it influences tumorigenesis.

Loss of SOCS1 in Donor T Cells Exacerbates Intestinal GVHD by Driving a Chemokine‐Dependent Pro‐Inflammatory Immune Microenvironment

Advanced Science, EarlyView.
T cell‐specific Socs1 knockout leads to inflammatory differentiation of CD8+ T cells, prompting the STAT1/2 complex to drive the activation of Ccl5, Ccr5, and Cxcr3, and promoting the skewing of monocytes toward a pro‐inflammatory M1 macrophage lineage.

NFкB is a critical transcriptional regulator of atypical cadherin FAT1 in glioma

BMC Cancer, 2020
Background Overexpression of FAT1 gene and its oncogenic effects have been reported in several cancers. Previously, we have documented upregulation of FAT1 gene in glioblastoma (GBM) tumors which was found to increase the expression of proinflammatory ...

RelA Is a Component of the Nutritional Stress Activation Pathway of theBacillus subtilisTranscription Factor σ^B [PDF]

Journal of Bacteriology, 2003
ABSTRACTThe general stress regulon ofBacillus subtilisis induced by the activation of the σBtranscription factor. Activation of σBoccurs when one of two phosphatases (RsbU and RsbP), each responding to a unique type of stress, actuates a positive regulator of σBby dephosphorylation. Nutritional stress triggers the RsbP phosphatase.

ETV4 Promotes Colorectal Cancer Progression by Reprogramming Asparagine Metabolism to Remodel the Stromal Microenvironment

Advanced Science, EarlyView.
ETV4 coordinates a dual transcriptional program by upregulating MET and asparagine synthetase (ASNS). The resulting asparagine (Asn) secretion acts as a metabolic signal, reprogramming hepatic stellate cells (HSCs) and primary cancer‐associated fibroblasts (CAFs) toward an inflammatory phenotype. These activated stromal cells release HGF to sustain the

Tobacco Smoke Exposure From Prenatal To Adolescent Periods Drives IBD Pathogenesis: Dynamic DNA Methylation Signatures Across Lifespan Stages

Advanced Science, EarlyView.
This study illustrates that maternal smoking during pregnancy (MSDP) is an independent risk factor for IBD in offspring, and DNA methylation serves as a key mechanistic pathway connecting early‐life smoking exposure with IBD risk in offspring. That highlights the urgent need for preventive interventions targeting prospective parents and minors to ...
