Transcriptional regulation of haematopoietic transcription factors [PDF]

Stem Cell Research & Therapy, 2011
The control of differential gene expression is central to all metazoan biology. Haematopoiesis represents one of the best understood developmental systems where multipotent blood stem cells give rise to a range of phenotypically distinct mature cell types, all characterised by their own distinctive gene expression profiles.

The T-cell oncogene Tal2 is a Target of PU.1 and upregulated during osteoclastogenesis [PDF]

, 2013
Transcription factors play a crucial role in regulating differentiation processes during human life and are important in disease. The basic helix-loop-helix transcription factors Tal1 and Lyl1 play a major role in the regulation of gene expression in the

Contrasting roles for G-quadruplexes in regulating human Bcl-2 and virus homologues KSHV KS-Bcl-2 and EBV BHRF1

Scientific Reports, 2022
Herpesviruses are known to acquire several genes from their hosts during evolution. We found that a significant proportion of virus homologues encoded by HSV-1, HSV-2, EBV and KSHV and their human counterparts contain G-quadruplex motifs in their ...

Information on Transcriptional Regulation and Signal Transduction of _Escherichia coli_ K-12 Integrated in the Database RegulonDB. [PDF]

, 2010
Since its inception, RegulonDB ("http://regulondb.ccg.unam.mx/":http://regulondb.ccg.unam.mx/) has been a database that compiles information about the regulation of transcription initiation of _Escherichia coli_ K-12. However, we are aware that

Microbiome analysis of saliva from oral squamous cell carcinoma (OSCC) patients and tobacco abusers with potential biomarkers for oral cancer screening

Heliyon, 2023
Oral squamous cell carcinoma (OSCC) is the most common type of oral cancer and accounts for about 95% of all head and neck cancers with high mortality, usually at a late stage.

Analysis of G-quadruplexes upstream of herpesvirus miRNAs: evidence of G-quadruplex mediated regulation of KSHV miR-K12–1-9,11 cluster and HCMV miR-US33

BMC Molecular and Cell Biology, 2020
Background G-quadruplexes regulate gene expression, recombination, packaging and latency in herpesviruses. Herpesvirus-encoded miRNAs have been linked to important biological functions. The presence and the biological role of G-quadruplexes have not been

Structural basis of copper-efflux-regulator-dependent transcription activation

iScience, 2021
Summary: The copper efflux regulator (CueR), a representative member of mercury resistance regulator (MerR) family metalloregulators, controls expression of copper homeostasis-regulating genes in bacteria.

Structural visualization of transcription activated by a multidrug-sensing MerR family regulator

Nature Communications, 2021
The MerR family of transcriptional regulators, such as EcmrR, activate promoters with a structure that is suboptimal for recognition by RNA polymerase holoenzyme. Structural insights into the EcmrR-dependent transcription process elucidate the mechanisms

Strong negative self regulation of Prokaryotic transcription factors increases the intrinsic noise of protein expression [PDF]

, 2008
Background Many prokaryotic transcription factors repress their own transcription. It is often asserted that such regulation enables a cell to homeostatically maintain protein abundance.
