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

Molecular 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

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

PLoS 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

Inactivation of L-type calcium channel modulated by HCN2 channel

American 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-

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

Molecular 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 ...

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.

Modeling L-type Calcium Channel with Dihydropyridines [PDF]

Biophysical 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 ...

Dimethyl fumarate combined with cisplatin at subcytotoxic doses sensitizes cervical cancer toward ferroptosis and apoptosis through GSH restriction and p53 (re)activation

Molecular Oncology, EarlyView.
Dimethyl fumarate (DMF) reduces growth of HPV‐positive cervical cancer spheroids and induces ferroptosis in cervical cancer cells via blocking SLC7A11/Glutathione (GSH) axis. Combination of subcytotoxic doses of DMF and cisplatin (CDDP) further suppresses spheroid growth and drives cell death in 2D culture models.

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.

Targeted modulation of IGFL2‐AS1 reveals its translational potential in cervical adenocarcinoma

Molecular Oncology, EarlyView.
Cervical adenocarcinoma patients face worse outcomes than squamous cell carcinoma counterparts despite similar treatment. The identification of IGFL2‐AS1's differential expression provides a molecular basis for distinguishing these histotypes, paving the way for personalized therapies and improved survival in vulnerable populations globally.

Amplification of a calcium channel subunit CACNG4 increases breast cancer metastasis

EBioMedicine, 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.
