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.

Mechanisms of T-type calcium channel blockade by zonisamide

Seizure, 1996
We investigated the effects of zonisamide, a new antiepileptic drug, on voltage-dependent T-type calcium current (ICa) in cultured neuroblastoma cells of human origin (NB-I). Zonisamide reduced T-type ICa in a concentration-dependent manner without evoking any change in its inactivation kinetics or voltage dependence of action.

Potential therapeutic targeting of BKCa channels in glioblastoma treatment

Molecular Oncology, EarlyView.
This review summarizes current insights into the role of BKCa and mitoBKCa channels in glioblastoma biology, their potential classification as oncochannels, and the emerging pharmacological strategies targeting these channels, emphasizing the translational challenges in developing BKCa‐directed therapies for glioblastoma treatment.

Functional characterization and analgesic effects of mixed cannabinoid receptor/T-type channel ligands

Molecular Pain, 2011
Background Both T-type calcium channels and cannabinoid receptors modulate signalling in the primary afferent pain pathway. Here, we investigate the analgesics activities of a series of novel cannabinoid receptor ligands with T-type calcium channel ...

Electron-conformational transformations in nanoscopic RyR channels govern both the heart's contraction and beating [PDF]

, 2011
We show that a simple biophysically based electron-conformational model of RyR channel is able to explain and describe on equal footing the oscillatory regime of the heart's cell release unit both in sinoatrial node (pacemaker) cells under normal ...

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.

T-type calcium channel blockers – new and notable

General physiology and biophysics, 2012
Since cloning of the T-type or Ca(V)3.n calcium channel family in 1998-1999 much progress was made in investigation of their regulation. Most effective metal Ca(V)3 channel blockers are trivalent cations from lanthanide group together with transition metals La(3+) and Y(3+).

Calcium signaling and T-type calcium channels in cancer cell cycling

World Journal of Gastroenterology, 2008
Regulation of intracellular calcium is an important signaling mechanism for cell proliferation in both normal and cancerous cells. In normal epithelial cells, free calcium concentration is essential for cells to enter and accomplish the S phase and the M phase of the cell cycle.

Plecstatin inhibits hepatocellular carcinoma tumorigenesis and invasion through cytolinker plectin

Molecular Oncology, EarlyView.
The ruthenium‐based metallodrug plecstatin exerts its anticancer effect in hepatocellular carcinoma (HCC) primarily through selective targeting of plectin. By disrupting plectin‐mediated cytoskeletal organization, plecstatin inhibits anchorage‐dependent growth, cell polarization, and tumor cell dissemination.
