KLF5 Downregulation Links Impaired BNIP3‐Mediated Mitophagy to Inflammatory Valve Remodeling in Calcific Aortic Valve Disease

Advanced Science, EarlyView.
In human CAVD, KLF5 is reduced in VIC‐rich regions and remodeling/stress‐associated VIC states. In VICs, KLF5 sustains BNIP3 promoter activity and BNIP3‐mediated mitophagy, thereby limiting cytosolic mtDNA accumulation. KLF5 loss weakens mitochondrial quality control and enhances mtDNA‐sensitive STING/NF‐κB/NLRP3 inflammatory signaling under osteogenic

The light chain of tetanus toxin inhibits calcium-dependent vasopressin release from permeabilized nerve endings [PDF]

, 1992
The effects of tetanus toxin and its light and heavy chain subunits on vasopressin release were investigated in digitonin-permeabilized neurosecretory nerve terminals isolated from the neural lobe of the rat pituitary gland.

Aspirin‐Derived Salicyl‐CoA Drives Histone Lysine Salicylation Regulated by CBP and SIRT2

Advanced Science, EarlyView.
Aspirin‐derived salicyl‐CoA serves as a previously unrecognized acyl donor for protein lysine salicylation. This study identifies histone lysine salicylation as a reversible epigenetic modification regulated by CBP and SIRT2, expanding the biochemical actions of aspirin beyond its canonical acetylation‐dependent mechanisms and providing a new framework

Rotational Diffusion of Rhodopsin-Digitonin Micelles Studied by Transient Photodichroism [PDF]

, 1971
The transient photodichroism induced by a 0.80 sec plane-polarized light flash in a rhodopsin-digitonin mixture at about -70°C was compared with a theoretical description of the effect.

DUET‐seq: An Open‐Source Droplet Platform for High‐Fidelity Joint Chromatin and Transcriptome Profiling Reveals Temporal Regulatory Decoupling in Single Cells

Advanced Science, EarlyView.
DUET‐seq is an open‐source droplet platform that jointly profiles chromatin accessibility and gene expression from the same nucleus. Dissolvable dual‐linker hydrogel beads and a one‐step intra‐droplet RT‐PCR co‐index both modalities in under 12 h at roughly $0.04 per cell.

Tissue and subcellular distribution of CLIC1

BMC Cell Biology, 2007
Background CLIC1 is a chloride channel whose cellular role remains uncertain. The distribution of CLIC1 in normal tissues is largely unknown and conflicting data have been reported regarding the cellular membrane fraction in which CLIC1 resides.

High-resolution model of Arabidopsis Photosystem II reveals the structural consequences of digitonin-extraction

Scientific Reports, 2021
In higher plants, the photosynthetic process is performed and regulated by Photosystem II (PSII). Arabidopsis thaliana was the first higher plant with a fully sequenced genome, conferring it the status of a model organism; nonetheless, a high-resolution ...

Clock Genes Regulate Ca2+ Signaling and Mitochondrial Bioenergetics to Inhibit Sjögren Disease

Arthritis &Rheumatology, EarlyView.
Objective Although Ca2+ signaling and metabolism have been identified as key determinants for the development of Sjögren disease (SjD), the intricate connection between them and salivary gland physiology remains poorly understood. Methods Fluorescence‐based Ca2+ imaging, RNA sequencing, and mitochondrial activity were used to investigate the effects of

Stimulation of specific binding of [H-3]-progesterone to bovine luteal cell-surface membranes: specificity of digitonin

, 1999
Non-genomic actions of progesterone have been described in the ovary, and luteal membranes of several species have been shown to possess specific binding sites for [H-3]-progesterone. However, binding of radiolabelled progesterone to luteal membranes was

Empirical PK/PD Model for Differentiating Intrinsic Dosing Rules by Therapeutic Indication With Relevance for HIV‐1 Latency Reversal

Clinical Pharmacology &Therapeutics, EarlyView.
Romidepsin (RMD), an FDA‐approved histone deacetylase inhibitor for treating cancer, demonstrates potent latency‐reversing activity in vitro but has yielded suboptimal outcomes in kick‐and‐kill HIV‐cure trials when administered as a 5 mg/m2 infusion.
