The dynamic assembly of distinct RNA polymerase I complexes modulates rDNA transcription

open access: yeseLife, 2017
Cell growth requires synthesis of ribosomal RNA by RNA polymerase I (Pol I). Binding of initiation factor Rrn3 activates Pol I, fostering recruitment to ribosomal DNA promoters.

Multiplexed activation of endogenous genes by CRISPR-on, an RNA-guided transcriptional activator system

open access: yesCell Research, 2013
Technologies allowing for specific regulation of endogenous genes are valuable for the study of gene functions and have great potential in therapeutics.

Structural basis of transcription activation [PDF]

open access: yesScience, 2016
Transcription activation all about timing Regulating transcription by RNA polymerase (RNAP) is central to controlling gene expression. Transcription factors influence the activity of the RNAP. Feng et al. determined the crystal structure of a bacterial transcription activation complex.

Regulation of bistability in the std fimbrial operon of Salmonella enterica by DNA adenine methylation and transcription factors HdfR, StdE and StdF [PDF]

open access: yes, 2019
Bistable expression of the Salmonella enterica std operon is controlled by an AND logic gate involving three transcriptional activators: the LysR-type factor HdfR and the StdE and StdF regulators encoded by the std operon itself.

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

open access: yesFEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Transcriptional Activation of Inflammatory Genes: Mechanistic Insight into Selectivity and Diversity

open access: yesBiomolecules, 2015
Acute inflammation, an integral part of host defence and immunity, is a highly conserved cellular response to pathogens and other harmful stimuli. An inflammatory stimulation triggers transcriptional activation of selective pro-inflammatory genes that ...

Keap1 represses nuclear activation of antioxidant responsive elements by Nrf2 through binding to the amino-terminal Neh2 domain.

open access: yesGenes & Development, 1999
Transcription factor Nrf2 is essential for the antioxidant responsive element (ARE)-mediated induction of phase II detoxifying and oxidative stress enzyme genes.

One-two punch mechanism of gene repression: a fresh perspective on gene regulation. [PDF]

open access: yes, 2017
Cellular differentiation depends on temporally controlled waves of gene activation and inactivation that ultimately transform one cell type into another.

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

open access: yesFEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Regulation of cAMP Responsive Element Binding Protein 3-Like 1 (Creb3l1) Expression by Orphan Nuclear Receptor Nr4a1

open access: yesFrontiers in Molecular Neuroscience, 2017
Cyclic AMP (cAMP) inducible transcription factor cAMP responsive element binding protein 3 like 1 (Creb3l1) is strongly activated in the hypothalamus in response to hyperosmotic cues such as dehydration (DH).
