Nanoscale architecture and dynamics of CaV1.3 channel clusters in cardiac myocytes revealed by single channel nanoscopy

Journal of Molecular and Cellular Cardiology Plus
The clustering of L-type calcium channels (LTCC) for functional regulation of intracellular calcium signaling remains poorly understood. Here we applied super-resolution imaging to study CaV1.3 channel clusters in human iPSC-derived atrial cardiomyocytes

Elevated Postsynaptic [Ca2+]iand L-Type Calcium Channel Activity in Aged Hippocampal Neurons: Relationship to Impaired Synaptic Plasticity

Journal of Neuroscience, 2001
Considerable evidence supports a Ca2+dysregulation hypothesis of brain aging and Alzheimer's disease. However, it is still not known whether (1) intracellular [Ca2+]i is altered in aged brain neurons during synaptically activated neuronal activity; (2 ...

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.

Voltage-gated calcium channels: Their discovery, function and importance as drug targets

Brain and Neuroscience Advances, 2018
This review will first describe the importance of Ca 2+ entry for function of excitable cells, and the subsequent discovery of voltage-activated calcium conductances in these cells.

Nimodipine in otolaryngology: from past evidence to clinical perspectives [PDF]

, 2015
As L-type voltage-gated calcium channels (VGCCs) control Ca(2+) influx and depolarisation of cardiac and vascular smooth muscle, they represent a specific therapeutic target for calcium channel blockers (CCBs), which are approved and widely used to treat

Evolutionary Covariant Positions within Calmodulin EF-hand Sequences Promote Ligand Binding [PDF]

, 2018
Intracellular calcium signaling is an essential regulatory mechanism through calcium-mediated signal transduction pathways involved in many cell processes, such as exocytosis, motility, apoptosis, excitability, transcription, and muscle contraction.

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.
