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

Molecular 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

Determinants of transcription factor regulatory range

Nature Communications, 2020
Characterization of the distance over which TF binding influences gene expression is important for inferring target genes. Here the authors study this relationship using thousands of genomic data sets, finding two classes of TFs with distinct ranges of ...

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

, 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 mutations in myelodysplastic/myeloproliferative neoplasms

Haematologica, 2010
Background Aberrant activation of tyrosine kinases, caused by either mutation or gene fusion, is of major importance for the development of many hematologic malignancies, particularly myeloproliferative neoplasms.

Transcription factor dynamics

Microbiology, 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.

Dynamics of gene expression and the regulatory inference problem

, 2008
From the response to external stimuli to cell division and death, the dynamics of living cells is based on the expression of specific genes at specific times.

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

Molecular 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 ...

Transcription Factor Networks in Drosophila melanogaster

Cell Reports, 2014
Specific cellular fates and functions depend on differential gene expression, which occurs primarily at the transcriptional level and is controlled by complex regulatory networks of transcription factors (TFs).

Human naive CD8 T cells down-regulate expression of the WNT pathway transcription factors lymphoid enhancer binding factor 1 and transcription factor 7 (T cell factor-1) following antigen encounter in vitro and in vivo [PDF]

, 2006
The transcription factors lymphoid enhancer binding factor 1 (LEF1) and transcription factor 7 (TCF7) (T cell factor-1 (TCF-1)) are downstream effectors of the WNT signaling pathway, which is a critical regulator of T cell development in the thymus.
