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.

Inhibition of RNA polymerase II transcription in human cells by synthetic DNA-binding ligands [PDF]

open access: yes, 1998
Sequence-specific DNA-binding small molecules that can permeate human cells potentially could regulate transcription of specific genes. Multiple cellular DNA-binding transcription factors are required by HIV type 1 for RNA synthesis.

Base-resolution models of transcription factor binding reveal soft motif syntax

open access: yesNature Genetics, 2019
The arrangement (syntax) of transcription factor (TF) binding motifs is an important part of the cis-regulatory code, yet remains elusive. We introduce a deep learning model, BPNet, that uses DNA sequence to predict base-resolution chromatin ...

Activating transcription factor 4-dependent hsa-miR-663a transcription mediates mTORC1/p70S6K1 signaling underleucine deprivation

open access: yesFrontiers in Nutrition, 2022
The mechanistic target of rapamycin complex 1 (mTORC1) is involved in nutrient-induced signaling and is a master regulator of cell growth and metabolism.

Structural basis of TFIIH activation for nucleotide excision repair. [PDF]

open access: yes, 2019
Nucleotide excision repair (NER) is the major DNA repair pathway that removes UV-induced and bulky DNA lesions. There is currently no structure of NER intermediates, which form around the large multisubunit transcription factor IIH (TFIIH).

Benchmark and integration of resources for the estimation of human transcription factor activities

open access: yesbioRxiv, 2018
Prediction of transcription factor (TF) activities from the gene expression of their targets (i.e. TF regulon) is becoming a widely-used approach to characterize the functional status of transcriptional regulatory circuits.

NTH201, a Novel Class II KNOTTED1-Like Protein, Facilitates the Cell-to-Cell Movement of Tobacco mosaic virus in Tobacco

open access: yesMolecular Plant-Microbe Interactions, 2008
NTH201, a novel class II KNOTTED1-like protein gene, was cloned from tobacco (Nicotiana tabacum cv. Xanthi) and its role in Tobacco mosaic virus (TMV) infection was analyzed. Virus-induced gene silencing of NTH201 caused a delay in viral RNA accumulation

Mud2 functions in transcription by recruiting the Prp19 and TREX complexes to transcribed genes [PDF]

open access: yes, 2007
The different steps of gene expression are intimately linked to coordinate and regulate this complex process. During transcription, numerous RNA-binding proteins are already loaded onto the nascent mRNA and package the mRNA into a messenger ...

Transcription factor dynamics

open access: yesMicrobiology, 2008
Gene expression is a fundamental process that is highly conserved from humans to bacteria. The first step in gene expression, transcription, is performed by structurally conserved DNA-dependent RNA polymerases (RNAPs), which results in the synthesis of an RNA molecule from a DNA template.

A patient‐derived explant (PDE) model of hormone‐dependent cancer

open access: yesMolecular Oncology, 2018
Breast and prostate cancer research to date has largely been predicated on the use of cell lines in vitro or in vivo. These limitations have led to the development of more clinically relevant models, such as organoids or murine xenografts that utilize ...
