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

Cell-Cycle Dependence of Transcription Dominates Noise in Gene Expression [PDF]

open access: yes, 2013
The large variability in mRNA and protein levels found from both static and dynamic measurements in single cells has been largely attributed to random periods of transcription, often occurring in bursts.

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 ...

RelA/NF-kappaB recruitment on the bax gene promoter antagonizes p73-dependent apoptosis in costimulated T cells [PDF]

open access: yes, 2008
The balance between antiapoptotic and proapoptotic proteins of the Bcl-2 family is critical in determining the fate of T cells in response to death stimuli.

Role of hepatitis B surface antigen in the development of hepatocellular carcinoma: regulation of lymphoid enhancer-binding factor 1 [PDF]

open access: yes, 2009
Background There are around 350 million of hepatitis B surface antigen (HBsAg) carriers worldwide, and among them, high risk of developing hepatocellular carcinoma (HCC) has been identified by epidemiological studies. To date, the molecular role of HBsAg

Posttranscriptional trans-activation in cauliflower mosaic virus

open access: yesCell, 1989
The ability of plant cells to translate dicistronic mRNAs that mimic a segment of the polycistronic 35S RNA from cauliflower mosaic virus has been tested. The chloramphenicol acetyltransferase and beta-glucuronidase open reading frames (ORFs) were fused in-frame to the second viral cistron (ORF I).

Mechanisms of stimulation of SAGA-mediated nucleosome acetylation by a transcriptional activator

open access: yesBiochemistry and Biophysics Reports, 2021
Eukaryotic gene expression requires the coordination of multiple factors to overcome the repressive nature of chromatin. However, the mechanistic details of this coordination are not well understood.

Lineage-specific Gene Expression in the Sea Urchin Embryo [PDF]

open access: yes, 1985
Within a few days of fertilization, the sea urchin embryo develops into a small differentiated organism consisting of about 1800 cells and capable of feeding, swimming, and the further ontogenic transformations required in the succeeding weeks of larval ...

Metabolomic and physiological analysis of bud differentiation in dense apple (Malus×domestica Borkh.) orchards following thinning and reshaping [PDF]

open access: yesPeerJ
Background In China, a majority of apple orchards were initially planted under arboriculture. The branch number increases, causing a deterioration of the canopy light conditions as the trees age.

Manipulating chromatin architecture in C. elegans

open access: yesEpigenetics & Chromatin, 2022
Background Nucleosome-mediated chromatin compaction has a direct effect on the accessibility of trans-acting activators and repressors to DNA targets and serves as a primary regulatory agent of genetic expression. Understanding the nature and dynamics of
