Structure and mechanisms of viral transcription factors in archaea [PDF]

, 2017
Virus-encoded transcription factors have been pivotal in exploring the molecular mechanisms and regulation of gene expression in bacteria and eukaryotes since the birth of molecular biology, while our understanding of viral transcription in archaea is ...

A MicroRNA Encoded by Autographa californica Nucleopolyhedrovirus Regulates Expression of Viral Gene ODV-E25 [PDF]

Journal of Virology, 2013
ABSTRACT Baculovirus-encoded microRNAs (miRNAs) have been described in Bombyx mori nucleopolyhedrovirus; however, most of their functions remain unclear. Here we report the identification and characterization of an miRNA encoded by Autographa californica nucleopolyhedrovirus.

The neural crest‐associated gene ERRFI1 is involved in melanoma progression and resistance toward targeted therapy

Molecular Oncology, EarlyView.
ERRFI1, a neural crest (NC)‐associated gene, was upregulated in melanoma and negatively correlated with the expression of melanocytic differentiation markers and the susceptibility of melanoma cells toward BRAF inhibitors (BRAFi). Knocking down ERRFI1 significantly increased the sensitivity of melanoma cells to BRAFi.

Aggregation of AcMNPV LEF-10 and Its Impact on Viral Late Gene Expression. [PDF]

PLoS ONE, 2016
The Autographa californica multiple nucleopolyhedrovirus (AcMNPV) late expression factor gene lef-10 has been identified to be required for viral late gene expression by transient expression assay. Our previous work has shown that the gene product LEF-10

Exploiting metabolic adaptations to overcome dabrafenib treatment resistance in melanoma cells

Molecular Oncology, EarlyView.
We show that dabrafenib‐resistant melanoma cells undergo mitochondrial remodeling, leading to elevated respiration and ROS production balanced by stronger antioxidant defenses. This altered redox state promotes survival despite mitochondrial damage but renders resistant cells highly vulnerable to ROS‐inducing compounds such as PEITC, highlighting redox

Emerging connections between small RNAs and phytohormones [PDF]

, 2020
Small RNAs (sRNAs), mainly including miRNAs and siRNAs, are ubiquitous in eukaryotes. sRNAs mostly negatively regulate gene expression via (post-)transcriptional gene silencing through DNA methylation, mRNA cleavage, or translation inhibition.

The interaction of HTLV-1 Tax with HDAC1 negatively regulates the viral gene expression [PDF]

Oncogene, 2002
Histone acetyltransferases (HATs) and histone deacetylases (HDACs) are known to interact with several transcription factors and regulate their transcriptional activities. The human T-cell leukemia virus type 1 (HTLV-1) Tax oncoprotein activates transcription from its long terminal repeat (LTR) through interaction with cellular factors such as CREB and ...

Recurrent cancer‐associated ERBB4 mutations are transforming and confer resistance to targeted therapies

Molecular Oncology, EarlyView.
We show that the majority of the 18 analyzed recurrent cancer‐associated ERBB4 mutations are transforming. The most potent mutations are activating, co‐operate with other ERBB receptors, and are sensitive to pan‐ERBB inhibitors. Activating ERBB4 mutations also promote therapy resistance in EGFR‐mutant lung cancer.

A viral genome landscape of RNA polyadenylation from KSHV latent to lytic infection. [PDF]

PLoS Pathogens, 2013
RNA polyadenylation (pA) is one of the major steps in regulation of gene expression at the posttranscriptional level. In this report, a genome landscape of pA sites of viral transcripts in B lymphocytes with Kaposi sarcoma-associated herpesvirus (KSHV ...

Critical Involvement of TFIIB in Viral Pathogenesis

Frontiers in Molecular Biosciences, 2021
Viral infections and the harm they cause to their host are a perpetual threat to living organisms. Pathogenesis and subsequent spread of infection requires replication of the viral genome and expression of structural and non-structural proteins of the ...
