Advanced Healthcare Materials, EarlyView.Ionizable lipid nanoparticles target multiple pathological pathways in neurodegeneration. The designed self‐assembled materials undergo a pH‐triggered structural transformation from a cubosome/hexosome coexistence to a hexosome phase, enhancing intracellular delivery of a multi‐target phytochemical formulation. The antioxidant‐loaded pH‐responsive LNPs

Tat gets the "green" light on transcription initiation
Retrovirology, 2005 Human immunodeficiency virus type 1 (HIV-1) Tat transactivation is an essential step in the viral life cycle. Over the past several years, it has become widely accepted that Tat exerts its transcriptional effect by binding the transactivation-responsive ...

Genomic analyses of transcription elongation factors and intragenic transcription
, 2023 Transcription of protein-coding genes in eukaryotic cells is carried out by the protein complex RNA polymerase II. During the elongation phase of transcription, RNA polymerase II associates with transcription elongation factors which modulate the activity of the transcription complex and are needed to carry out co-transcriptional processes.

Dysregulation of Positive Transcription Elongation Factor b and Myocardial Hypertrophy [PDF]
Circulation Research, 2009 See related articles, pages 1347–1354 Prolonged stimulus of the adult heart by hypertension, arrhythmias, or other pathogenic conditions can result in myocardial hypertrophy and subsequently heart failure. Hypertrophy is characterized by an increase in the size of cardiomyocytes and this is associated with an elevated rate of RNA synthesis and ...

Adenovirus E1A Activation Domain Regulates H3 Acetylation Affecting Varied Steps in Transcription at Different Viral Promoters. [PDF]
, 2018 How histone acetylation promotes transcription is not clearly understood. Here, we confirm an interaction between p300 and the adenovirus 2 large E1A activation domain (AD) and map the interacting regions in E1A by observing colocalization at an ...

Transcription Elongation Factor GreA Has Functional Chaperone Activity
PLoS ONE, 2012 Bacterial GreA is an indispensable factor in the RNA polymerase elongation complex. It plays multiple roles in transcriptional elongation, and may be implicated in resistance to various stresses.In this study, we show that Escherichia coli GreA inhibits aggregation of several substrate proteins under heat shock condition.
