Canadine synthase from Thalictrum tuberosum cell cultures catalyses the formation of the methylenedioxy bridge in berberine synthesis [PDF]

open access: yes, 1994
An enzyme system catalysing the formation of the methylenedioxy bridge at ring A of (S)-canadine [ = (S)-tetrahydroberberine] from (S)-tetrahydrocolumbamine has been detected in microsomal preparations from different Ranunculaceae and Berberidaceae cell ...

Bridging the Gap Between Human Toxicology and Ecotoxicology Under One Health Perspective by a Cross‐Species Adverse Outcome Pathway Network for Reproductive Toxicity

open access: yesEnvironmental Toxicology and Chemistry, EarlyView.
Cross‐species extrapolation of adverse outcome pathway network on reproductive toxicity under the One Health perspective using new approach methodologies. AOP = adverse outcome pathway. Abstract Although ecotoxicological and toxicological risk assessments are performed separately from each other, recent efforts have been made in both disciplines to ...

Phenolic metabolites of anthocyanins modulate mechanisms of endothelial function [PDF]

open access: yes, 2015
Anthocyanins are reported to have vascular bioactivity, however their mechanisms of action are largely unknown. Evidence suggests that anthocyanins modulate endothelial function, potentially by increasing nitric oxide (NO) synthesis, or enhancing NO ...

STIP1 drives Metabolic Reprogramming in Esophageal Squamous Cell Carcinoma via AHCY‐LDHA Axis

open access: yesExploration, EarlyView.
A schematic model illustrating that LCA can inhibit ESCC growth by inhibiting the STIP1/AHCY/LDHA axis. In brief. Jin et al. demonstrated that targeting STIP1 can significantly inhibit the progression of esophageal squamous cell carcinoma. The high expression of STIP1 increased the interaction between AHCY and LDHA and then AHCY recruits PRMT3 to ...

Exploring the Neuroprotective Role of Selenium: Implications and Perspectives for Central Nervous System Disorders

open access: yesExploration, EarlyView.
Selenium (Se) is a crucial element in selenoproteins, key biomolecules for physiological function in vivo. Central nervous system can express all 25 kinds of selenoproteins, which protect neurons by reducing oxidative stress and inflammatory response. Neuroprotection is being investigated through the biological study of Se.

Roles of NADPH Oxidase in Occurrence of Gastric Damage and Expression of Cyclooxygenase-2 During Ischemia/Reperfusion in Rat Stomachs

open access: yesJournal of Pharmacological Sciences, 2009
NADPH oxidase is an enzyme that converts molecular oxygen into reactive oxygen species, which cause severe damage in several organs. Cyclooxygenase (COX)-2 is an inducible enzyme that is important in gastric mucosal defense and repair processes.

ABCG1 Attenuates Oxidative Stress Induced by H2O2 through the Inhibition of NADPH Oxidase and the Upregulation of Nrf2-Mediated Antioxidant Defense in Endothelial Cells

open access: yesAnalytical Cellular Pathology, 2020
Summary. Oxidative stress is an important factor that is related to endothelial dysfunction. ATP-binding cassette transporter G1 (ABCG1), a regulator of intracellular cholesterol efflux, has been found to prevent endothelial activation in vessel walls ...
