Electrochemistry of potentially bioreductive alkylating quinones: Part 1. Electrochemical properties of relatively simple quinones, as model compounds of mitomycin- and aziridinylquinone-type antitumour agents [PDF]

open access: yes, 1990
The influence of methyl-, hydroxy and amino substituents on the electrochemical behaviour of simple 1,4-naphtho-and 1,4-benzoquinones, model compounds of many quinoid antitumour agents, in aqueous media was studied. Significant changes in electrochemical

Ischaemic stroke and 5‐fluorouracil or capecitabine: A systematic review and meta‐analysis of harms and a retrospective study of the WHO pharmacovigilance database

open access: yesBritish Journal of Pharmacology, EarlyView.
Abstract Aim Fluoropyrimidines, including 5‐fluorouracil (5‐FU) and capecitabine, are cornerstone antineoplastic agents for cancer. Case reports suggest that these drugs may be associated with an under‐recognised risk of ischaemic stroke or transient ischaemic attack (TIA).

Zeb2 Controls Retinal Physiological and Pathological Angiogenesis by Regulating Astrocyte Proliferation and Differentiation

open access: yesCell Proliferation, EarlyView.
During development, the oxygen‐sensitive transcription factor Zeb2 restrains astrocyte proliferation and maturation to ensure balanced retinal angiogenesis. In disease, it promotes the neurotoxic A1 astrocyte phenotype and inflammation, thereby promoting reparative revascularization over pathological neovascularization.

GCN2 in proteostasis: structural logic, signalling networks and disease

open access: yesThe FEBS Journal, EarlyView.
Threats to protein synthesis activate the kinase GCN2, initiating the integrated stress response (ISR). GCN2 is triggered by stalled ribosomes and uncharged tRNAs, which accumulate when amino acids are scarce. The ISR adjusts cellular physiology by promoting redox balance, protein quality control, and mitochondrial optimisation.

Physiological media and oxygen levels modulate cancer hallmarks in cultured breast cancer cells

open access: yesThe FEBS Journal, EarlyView.
MCF7 breast cancer cells were cultured in standard conditions (18% O2 and DMEM) and physiological conditions (5% O2 and Plasmax, a medium modeled after the human plasma metabolome). A combined transcriptomic and proteomic approach was used to identify gene expression signatures at the mRNA and protein levels upstream of functional enrichment analyses ...

A Convergent Approach to the Mitomycin Ring System

open access: yes, 2016
A novel stereoselective approach to the ring system of the mitomycins is described. The synthesis was based on a convergent strategy involving a stereocontrolled addition of a β-phenyl silyl enol ether to a pyrroline N-acyliminium ion followed by an ...

Far‐infrared irradiation attenuates platelet‐derived growth factor‐stimulated vascular smooth muscle cell migration through protein phosphatase 2A‐mediated Akt inhibition

open access: yesPhotochemistry and Photobiology, EarlyView.
FIR irradiation enhances the physical association between Akt and PP2Ac in VSMCs, independent of the hyperthermal effect of FIR rays. The increased binding between Akt and PP2Ac induced by FIR irradiation facilitates the dephosphorylation of Akt at Ser473.

Inhibition of P‐glycoprotein using photoimmunotherapy in peritoneal metastasis mouse model

open access: yesPhotochemistry and Photobiology, EarlyView.
Photoimmunotherapy (PIT) using photoimmunoconjugates (PICs) can inhibit the function of the ATP‐binding cassette (ABC) transporter P‐glycoprotein (P‐gp) in a mouse model of peritoneal carcinomatosis. Sterile‐filtered PIC was administered in vivo via intraperitoneal (IP) injection 20 days after IP tumor cell implantation of P‐gp‐overexpressing NCI/ADR ...

Identification of Novel Therapeutic Agent Candidates Through High Throughput Screening With Chemical Library Based on Molecular Subclassification in Canine Histiocytic Sarcoma Cell Lines

open access: yesVeterinary and Comparative Oncology, EarlyView.
ABSTRACT Effective chemotherapy for canine histiocytic sarcoma (CHS) has yet to be established. In our previous study, CHS cell lines were subclassified into two groups based on their gene expression profiles: Group A and Group B. This study aimed to identify novel therapeutic agents that are effective against each CHS subgroup, and we performed high ...
