Molecular Oncology, EarlyView.Pharmacologic ascorbate (vitamin C) increases ROS, disrupts cellular metabolism, and induces DNA damage in CRPC cells. These effects sensitize tumors to PARP inhibition, producing synergistic growth suppression with olaparib in vitro and significantly delayed tumor progression in vivo. Pyruvate rescue confirms ROS‐dependent activity.

Clathrin Heavy Chain subunits coordinate endo- and exocytic traffic and affect stomatal movement [PDF]
, 2017 The current model for vesicular traffic to and from the plasma membrane is accepted but the molecular requirements for this coordination are not well defined.

SNARE Protein-Dependent Glutamate Release from Astrocytes [PDF]
The Journal of Neuroscience, 2000 We investigated the cellular mechanisms underlying the Ca2+-dependent release of glutamate from cultured astrocytes isolated from rat hippocampus. Using Ca2+imaging and electrophysiological techniques, we analyzed the effects of disrupting astrocytic vesicle proteins on the ability of astrocytes to release glutamate and to cause neuronal ...

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.

SNARE Proteins Underpin Insulin‐Regulated GLUT4 Traffic [PDF]
Traffic, 2011 Delivery of the glucose transporter type 4 (GLUT4) from an intracellular location to the cell surface in response to insulin represents a specialized form of membrane traffic, known to be impaired in the disease states of insulin resistance and type 2 diabetes.

Molecular Oncology, EarlyView.Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

Phosphorylation of Ykt6 SNARE Domain Regulates Its Membrane Recruitment and Activity
Biomolecules, 2020 Sensitive factor attachment protein receptors (SNARE) proteins are important mediators of protein trafficking that regulate the membrane fusion of specific vesicle populations and their target organelles.

Targeting SNARE-Mediated Vesicle Transport to Block Invadopodium-Based Cancer Cell Invasion
Frontiers in Oncology, 2021 During metastasis, cancer cells can invade extracellular matrix (ECM) through a process mediated by matrix-degrading protrusions of the plasma membrane, termed invadopodia. Formation of invadopodia correlates with cells’ invasive and metastatic potential,

A comparative analysis of trypanosomatid SNARE proteins
Parasitology International, 2014 The Kinetoplastida are flagellated protozoa evolutionary distant and divergent from yeast and humans. Kinetoplastida include trypanosomatids, and a number of important pathogens. Trypanosoma brucei, Trypanosoma cruzi and Leishmania spp. inflict significant morbidity and mortality on humans and livestock as the etiological agents of human African ...
