Aggressive prostate cancer is associated with pericyte dysfunction

Molecular Oncology, EarlyView.
Tumor‐produced TGF‐β drives pericyte dysfunction in prostate cancer. This dysfunction is characterized by downregulation of some canonical pericyte markers (i.e., DES, CSPG4, and ACTA2) while maintaining the expression of others (i.e., PDGFRB, NOTCH3, and RGS5).

Dual targeting of RET and SRC synergizes in RET fusion‐positive cancer cells

Molecular Oncology, EarlyView.
Despite the strong activity of selective RET tyrosine kinase inhibitors (TKIs), resistance of RET fusion‐positive (RET+) lung cancer and thyroid cancer frequently occurs and is mainly driven by RET‐independent bypass mechanisms. Son et al. show that SRC TKIs significantly inhibit PAK and AKT survival signaling and enhance the efficacy of RET TKIs in ...

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.

Detection of circulating tumor DNA in colorectal cancer patients using a methylation‐specific droplet digital PCR multiplex

Molecular Oncology, EarlyView.
We developed a cost‐effective methylation‐specific droplet digital PCR multiplex assay containing tissue‐conserved and tumor‐specific methylation markers. The assay can detect circulating tumor DNA with high accuracy in patients with localized and metastatic colorectal cancer.

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.

L-type calcium channel modulates cystic kidney phenotype

Biochimica et Biophysica Acta (BBA) - Molecular Basis of Disease, 2014
In polycystic kidney disease (PKD), abnormal proliferation and genomic instability of renal epithelia have been associated with cyst formation and kidney enlargement. We recently showed that L-type calcium channel (CaV1.2) is localized to primary cilia of epithelial cells.

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

Cell surface interactome analysis identifies TSPAN4 as a negative regulator of PD‐L1 in melanoma

Molecular Oncology, EarlyView.
Using cell surface proximity biotinylation, we identified tetraspanin TSPAN4 within the PD‐L1 interactome of melanoma cells. TSPAN4 negatively regulates PD‐L1 expression and lateral mobility by limiting its interaction with CMTM6 and promoting PD‐L1 degradation.

Apoptotic Cell Death and Impairment of L-Type Voltage-Sensitive Calcium Channel Activity in Rat Cerebellar Granule Cells Treated with the Prion Protein Fragment 106–126

Neurobiology of Disease, 2000
Prion diseases are neurodegenerative pathologies characterized by the accumulation, in the brain, of altered forms of the prion protein (PrP), named PrPSc.
