RNF12 activates Xist and is essential for X chromosome inactivation. [PDF]

open access: yesPLoS Genetics, 2011
In somatic cells of female placental mammals, one of the two X chromosomes is transcriptionally silenced to accomplish an equal dose of X-encoded gene products in males and females.

Functional comparison of the Rev trans-activators encoded by different primate immunodeficiency virus species.

open access: yesProceedings of the National Academy of Sciences of the United States of America, 1989
The known primate lentiviruses can be divided into two subgroups consisting of the human immunodeficiency virus type 1 (HIV-1) isolates and the related HIV type 2 (HIV-2) and simian immunodeficiency virus (SIV) isolates.

Cancer cell employs a microenvironmental neural signal trans-activating nucleus-mitochondria coordination to acquire stemness

open access: yesSignal Transduction and Targeted Therapy, 2023
Cancer cell receives extracellular signal inputs to obtain a stem-like status, yet how tumor microenvironmental (TME) neural signals steer cancer stemness to establish the hierarchical tumor architectures remains elusive.

A Novel Method for Gene-Specific Enhancement of Protein Translation by Targeting 5'UTRs of Selected Tumor Suppressors. [PDF]

open access: yesPLoS ONE, 2016
BACKGROUND:Translational control is a mechanism of protein synthesis regulation emerging as an important target for new therapeutics. Naturally occurring microRNAs and synthetic small inhibitory RNAs (siRNAs) are the most recognized regulatory molecules ...

Analysis of the Orgyia pseudotsugata multicapsid nuclear polyhedrosis virus trans-activators IE-1 and IE-2 using monoclonal antibodies.

open access: yesJournal of General Virology, 1993
We have produced monoclonal antibodies against two Orgyia pseudotsugata multicapsid nuclear polyhedrosis virus (OpMNPV) transcriptional trans-activators, IE-1 and IE-2.

Molecular Characterization of Heat-Induced HSP11.0 and Master-Regulator HSF from Cotesia chilonis and Their Consistent Response to Heat Stress

open access: yesInsects, 2021
Small heat shock proteins (sHSPs) are members of the heat shock protein (HSP) family that play an important role in temperature stress, and heat shock factors (HSFs) are transcriptional activators that regulate HSP expression. Cotesia chilonis, the major

An emerging and variant viral promoter of HIV-1 subtype C exhibits low-level gene expression noise

open access: yesRetrovirology, 2021
Background We observe the emergence of several promoter-variant viral strains in India during recent years. The variant viral promoters contain additional copies of transcription factor binding sites present in the viral modulatory region or enhancer ...

Synergy between HIV-1 Tat and adenovirus E1A is principally due to stabilization of transcriptional elongation [PDF]

open access: yes, 1990
We studied the combined effects of Tat and general trans-activators, such as E1A and phorbol esters, on human immunodeficiency virus-1 (HIV-1) gene expression. Interaction between these two types of trans-activators may be involved in the transition from

Negative regulation of Sp1 trans-activation is correlated with the binding of cellular proteins to the amino terminus of the Sp1 trans-activation domain. [PDF]

open access: yesJournal of Biological Chemistry, 1994
Sp1 is a well characterized and ubiquitously expressed transcription factor that regulates the constitutive and induced expression of a variety of mammalian genes. It is unclear whether Sp1 activity is regulated in vivo; the mechanism by which Sp1 interacts with the basal transcription complex has not been firmly established.

Cross regulation of sirtuin 1, AMPK, and PPARγ in conjugated linoleic acid treated adipocytes. [PDF]

open access: yesPLoS ONE, 2012
Trans-10, cis-12 conjugated linoleic acid (t10c12 CLA) reduces triglyceride (TG) levels in adipocytes through multiple pathways, with AMP-activated protein kinase (AMPK) generally facilitating, and peroxisome proliferator-activated receptor γ (PPARγ ...
