The Mitochondrial Ca(2+) Uniporter: Structure, Function, and Pharmacology. [PDF]

open access: yes, 2017
Mitochondrial Ca(2+) uptake is crucial for an array of cellular functions while an imbalance can elicit cell death. In this chapter, we briefly reviewed the various modes of mitochondrial Ca(2+) uptake and our current understanding of mitochondrial Ca(2+)

Polyamines and potassium channels: A 25-year romance

open access: yesJournal of Biological Chemistry, 2018
Potassium channels that exhibit the property of inward rectification (Kir channels) are present in most cells. Cloning of the first Kir channel genes 25 years ago led to recognition that inward rectification is a consequence of voltage-dependent block by

Uric Acid in Metabolic Dysfunction‐Associated Steatotic Liver Disease

open access: yesPortal Hypertension &Cirrhosis, EarlyView.
MASLD is the most prevalent chronic liver disease worldwide, yet effective pharmacological treatments remain limited. Hyperuricemia is now recognized as a key driver of hepatic steatosis, inflammation, and fibrosis, with elevated serum uric acid levels independently predicting hepatocellular carcinoma and liver‐related mortality.

Exploring polyamines: Functions in embryo/fetal development

open access: yesAnimal Nutrition, 2017
Polyamines such as putrescine, spermidine, spermine and agmatine are aliphatic polycationic compounds present in all living cells, and are derived from amino acids, intestinal bacteria, exfoliated enterocytes and supported from diet.

The antizyme family for regulating polyamines

open access: yesJournal of Biological Chemistry, 2018
The polyamines spermidine, spermine, and their precursor putrescine are organic polycations involved in various cellular processes and are absolutely essential for cellular proliferation. Because of their crucial function in the cell, their intracellular

FM1-43 dye behaves as a permeant blocker of the hair-cell mechanotransducer channel [PDF]

open access: yes, 2001
Hair cells in mouse cochlear cultures are selectively labeled by brief exposure to FM1-43, a styryl dye used to study endocytosis and exocytosis. Real-time confocal microscopy indicates that dye entry is rapid and via the apical surface.

Boron‐10 carriers and their applications in boron neutron capture therapy

open access: yesPrecision Radiation Oncology, EarlyView.
Summary of different types of boron drugs. Abstract Boron neutron capture therapy (BNCT) has emerged as a promising therapeutic modality in cancer treatment, demonstrating the ability to selectively eliminate cancer cells through the 10B(n,α)7Li nuclear reaction with minimal side effects on normal tissues.

Putrescine alleviates cold injury in peach fruit via elevating the conjugated polyamines in tonoplast and thereby maintaining vacuole conformation

open access: yesHorticultural Science
Exogenous polyamines can elevate postharvest fruit cold resistance and alleviate cold injury. However, the mechanism, by which polyamines mediate cold tolerance, is still to be explored.
