T Cell Receptor Mediated Calcium Entry Requires Alternatively Spliced Cav1.1 Channels. [PDF]

open access: yesPLoS ONE, 2016
The process of calcium entry in T cells is a multichannel and multi-step process. We have studied the requirement for L-type calcium channels (Cav1.1) α1S subunits during calcium entry after TCR stimulation. High expression levels of Cav1.1 channels were

Plecstatin inhibits hepatocellular carcinoma tumorigenesis and invasion through cytolinker plectin

open access: yesMolecular 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.

Inactivation of L-type calcium channel modulated by HCN2 channel

open access: yesAmerican Journal of Physiology-Cell Physiology, 2010
Ca2+ entry is delicately controlled by inactivation of L-type calcium channel (LTCC) composed of the pore-forming subunit α1C and the auxiliary subunits β1 and α2δ. Calmodulin is the key protein that interacts with the COOH-terminal motifs of α1C, leading to the fine control of LTCC inactivation. In this study we show evidence that a hyperpolarization-

Therapeutic strategies for MMAE‐resistant bladder cancer through DPP4 inhibition

open access: yesMolecular Oncology, EarlyView.
We established monomethyl auristatin E (MMAE)‐resistant bladder cancer (BC) cell lines by exposure to progressively increasing concentrations of MMAE in vitro. RNA sequencing showed DPP4 expression was increased in MMAE‐resistant BC cells. Both si‐DPP4 and the DPP4 inhibitor sitagliptin suppressed the viability of MMAE‐resistant BC cells.

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

open access: yesBrain 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.

Identification and Subcellular Localization of the Subunits of L-type Calcium Channels and Adenylyl Cyclase in Cardiac Myocytes*

open access: yesJournal of Biological Chemistry, 1997
The properties of cardiac L-type channels have been well characterized electrophysiologically, and many such studies have demonstrated that the channels are regulated by a cAMP-dependent pathway.

Modeling L-type Calcium Channel with Dihydropyridines [PDF]

open access: yesBiophysical Journal, 2009
Dyhydropyridines (DHPs) is a major class of L-type calcium channel (LCC) ligands, which have boat-like six-membered ring with NH-group at the stern, aromatic moiety at the bow, and various substituents at the port and starboard sides. DHPs demonstrate antagonistic or agonistic action, which was previously explained as stabilization or destabilization ...

The PI3Kδ inhibitor roginolisib (IOA‐244) preserves T‐cell function and activity

open access: yesMolecular Oncology, EarlyView.
Identification of novel PI3K inhibitors with limited immune‐related adverse effects is highly sought after. We found that roginolisib and idelalisib inhibit chronic lymphocytic leukemia (CLL) cells and Treg suppressive functions to similar extents, but roginolisib affects cytotoxic T‐cell function and promotion of pro‐inflammatory T helper subsets to a

Amplification of a calcium channel subunit CACNG4 increases breast cancer metastasis

open access: yesEBioMedicine, 2020
Background: Previously, we found that amplification of chromosome 17q24.1-24.2 is associated with lymph node metastasis, tumour size, and lymphovascular invasion in invasive ductal carcinoma.

Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

open access: yesMolecular Oncology, EarlyView.
Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...
