Functional comparison of EncB and EncC cargo proteins in iron storage within the Myxococcus xanthus encapsulin

FEBS Letters, EarlyView.
Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

The self-maintaining nature of ventricular fibrillation : contribution of L-type Ca²+ channels and Na+/Ca²+ exchange to cardiomyocyte Ca²+ overload in ventricular fibrillation : surface fluorescence study in isolated perfused rat hearts [PDF]

, 2004
Approximately 40% of all deaths in Switzerland are due to cardiovascular diseases.1 An important part of these deaths happen because of life-threatening cardiac arrhythmias.

Modeling L-type Calcium Channel with Phenylalkylamines [PDF]

Biophysical Journal, 2009
Phenylalkylamines (PAAs), a major class of L-type calcium channel (LCC) blockers, have aromatic rings A and B connected by a flexible chain with cyano and ammonium groups proximal to rings A and B, respectively. Structural aspects of ligand-channel interactions remain unclear.

USP29‐regulated noncanonical stabilization of the hypoxia‐inducible factor‐α in aggressive prostate cancer

Molecular Oncology, EarlyView.
We identify USP29 as the only DUB mirroring CA9 expression, a marker of hypoxia and HIF pathway activation associated with PCA aggressiveness. USP29 stabilizes HIF‐1α and HIF‐2α via a noncanonical mechanism that is independent of PHD/pVHL activity yet relies on proteasomal regulation, establishing USP29 as a previously unrecognized regulator of hypoxic

Group I metabotropic glutamate receptor plasticity after peripheral inflammation alters nociceptive transmission in the dorsal horn of the spinal cord in adult rats

Molecular Pain, 2017
The dorsal horn of the spinal cord is a crucial site for pain transmission and modulation. Dorsal horn neurons of the spinal cord express group I metabotropic glutamate receptors (group I mGluRs) that exert a complex role in nociceptive transmission.

Oncogenic DMTF1β promotes cancer cell motility by regulating autophagy through ULK1 stabilization

Molecular Oncology, EarlyView.
In the current study, we demonstrate that the oncogene DMTF1β regulates ULK1 stability by reducing its proteasomal degradation in cancer cells. This stabilization enables ULK1 to induce autophagy, which in turn facilitates cancer cell migration. Consequently, reduced DMTF1β levels lead to decreased autophagy and impaired cancer cell migration.

Molecular mechanism of Spinocerebellar Ataxia type 6: glutamine repeat disorder, channelopathy and transcriptional dysregulation. The multifaceted aspects of a single mutation. [PDF]

, 2015
Spinocerebellar Ataxia type 6 (SCA6) is an autosomal dominant neurodegenerative disease characterized by late onset, slowly progressive, mostly pure cerebellar ataxia. It is one of three allelic disorders associated to CACNA1A gene, coding for the Alpha1

An Indole Alkaloid Extracted from Evodia rutaecarpa Inhibits Colonic Motility of Rats In Vitro

Gastroenterology Research and Practice, 2020
Evodiamine (Evo) is an indole alkaloid extracted from the traditional Chinese medicinal herb Evodia rutaecarpa. Evo may regulate gastrointestinal motility, but the evidence is insufficient, and the mechanisms remain unknown.

Loss of proton‐sensing TDAG8 increases tumor progression in mouse models of colon cancer

Molecular Oncology, EarlyView.
Loss of the pH‐sensing receptor TDAG8 accelerates colorectal cancer progression in mice. Animals lacking TDAG8 expression had increased tumor growth, DNA damage, and recruitment of tumor‐associated immune cells, including macrophages, neutrophils, and monocytes.

Role of Calcium Channels in the Protective Effect of Hydrogen Sulfide in Rat Cardiomyoblasts

Cellular Physiology and Biochemistry, 2014
Background: Hydrogen sulfide contributes to the reduction of oxidative stress-related injury in cardiomyocytes but the underlying mechanism is still unclear. Aims: Here we investigated the role of voltage-operated calcium channels (VOCCs) as mediators of
