Th1/Th2 polarization of peripheral immune response in atherothrombotic and cardioembolic stroke: a prospective study

open access: yesScientific Reports, 2022
Compelling evidence suggest a key role of immune system in the development and progression of ischemic stroke. Although the balance between proinflammatory CD4 + T helper (Th)-1 lymphocytes, expressing T-bet transcription factor, and anti-inflammatory ...

Variable structure motifs for transcription factor binding sites [PDF]

open access: yes, 2010
Background: Classically, models of DNA-transcription factor binding sites (TFBSs) have been based on relatively few known instances and have treated them as sites of fixed length using position weight matrices (PWMs).

Developmental programmes drive cellular plasticity, disease progression and therapy resistance in lung adenocarcinoma

open access: yesMolecular Oncology, EarlyView.
This study shows that lung adenocarcinomas exploit developmental branching morphogenesis to acquire a therapy resistant basal‐like tumour cell state. This process was found to be regulated by combined TP53 loss‐of‐function and type‐I interferon signalling, identifying a novel axis for biomarker and therapeutic target discovery.

Immunophenotyping of circulating T helper cells argues for multiple functions and plasticity of T cells in vivo in humans--possible role in asthma.

open access: yesPLoS ONE, 2012
BackgroundThe immune process driving eosinophilic and non-eosinophilic asthma is likely driven by different subsets of T helper (Th) cells. Recently, in vitro studies and animal studies suggest that Th cell subsets displays plasticity by changing their ...

Dynamic expression of transcription factors T-bet and GATA-3 by regulatory T cells maintains immunotolerance [PDF]

open access: yesNature Immunology, 2014
Regulatory T cells (Treg cells) can express the transcription factors T-bet and GATA-3, but the function of this expression and whether such cells represent stable subsets is still unknown. By using various reporter tools, we found that the expression of T-bet and GATA-3 in Treg cells was dynamically influenced by the cytokine environment.

open access: yes, 2019
Transcription factors are proteins that bind to specific DNA sequences and regulate the transcription of genetic information from DNA to messenger RNA (mRNA). They are found in all living organisms. https://www.profacgen.com/transcription-factor-analysis.

An R2R3 MYB transcription factor associated with regulation of the anthocyanin biosynthetic pathway in Rosaceae [PDF]

open access: yes, 2010
Background The control of plant anthocyanin accumulation is via transcriptional regulation of the genes encoding the biosynthetic enzymes. A key activator appears to be an R2R3 MYB transcription factor.

Finding novel vulnerabilities of hypomorphic BRCA1 alleles

open access: yesMolecular Oncology, EarlyView.
Synthetic lethality screens performed to identify novel vulnerabilities often model complete gene loss, thereby overlooking patient‐derived hypomorphic mutations. In this study, we have performed genome‐wide CRISPR screens on BRCA1 hypomorphic mutations, showing BRCA1I26A behaves like wild‐type, while BRCA1R1699Q mimics deficiency. Furthermore, we have

Salvia miltiorrhiza inhibits the expressions of transcription factor T-bet (T-bet) and tumor necrosis factor α (TNFα) in the experimental colitis in mice

open access: yesAFRICAN JOURNAL OF BIOTECHNOLOGY, 2012
Salvia miltiorrhiza (SM) is mainly used for the treatment of coronary heart disease in china and it also represses inflammation, but the mechanism is not well known. This study aimed to investigate the effects of SM powder for injection on the expressions of transcription factor T-bet (T-bet) and tumor necrosis factor α (TNFα) in the experimental ...

Oncogenic DMTF1β promotes cancer cell motility by regulating autophagy through ULK1 stabilization

open access: yesMolecular Oncology, EarlyView.
In the current study, we demonstrate that the oncogene DMTF1β regulates ULK1 stability by reducing its proteasomal degradation in cancer cells. This stabilization enables ULK1 to induce autophagy, which in turn facilitates cancer cell migration. Consequently, reduced DMTF1β levels lead to decreased autophagy and impaired cancer cell migration.
