Human Dental Pulp Stem Cell Secretome Restores Ischemic Stroke–Impaired Motor and Cognitive Functions by Reprogramming Redox and Inflammatory Signaling

Advanced Science, EarlyView.
Human dental pulp stem cell secretome emerges as a cell‐free therapeutic strategy for ischemic stroke by reprogramming redox and inflammatory signaling. hDPSC secretome‐derived antioxidant and immunomodulatory factors suppress the TLR4–NOX–ROS–NF‐κB axis, reduce microglial inflammatory responses and apoptosis, and promote neurogenesis, angiogenesis ...

Formation of 1-octen-3-ol from Aspergillus flavus conidia is accelerated after disruption of cells independently of Ppo oxygenases, and is not a main cause of inhibition of germination [PDF]

PeerJ, 2014
Eight-carbon (C8) volatiles, such as 1-octen-3-ol, are ubiquitous among fungi. They are the volatiles critical for aroma and flavor of fungi, and assumed to be signals controlling germination of several fungi.

Hypothalamic Control of Liver Health and Disease: From Circuits to Pathophysiology and Therapies

Advanced Science, EarlyView.
This review delineates the hypothalamic circuits that control liver homeostasis via autonomic and neuroendocrine pathways. Dysregulation of this hypothalamus–liver axis drives disease progression across a spectrum including steatotic liver disease, liver inflammation and injury, fibrosis, cirrhosis, and hepatocellular carcinoma.

Protective Effects of Inducible HO-1 on Oxygen Toxicity in Rat Brain Endothelial Microvessel Cells [PDF]

Endocrinology and Metabolism, 2014
BackgroundReperfusion in ischemia is believed to generate cytotoxic oxidative stress, which mediates reperfusion injury. These stress conditions can initiate lipid peroxidation and damage to proteins, as well as promote DNA strand breaks.

The Antidiabetic Potential of Alpha‐Mangostin: A Review of Preclinical and Clinical Evidence

AgriFood: Journal of Agricultural Products for Food, EarlyView.
Alpha‐mangostin is a compound from the pericarp of Garcinia mangostana. The antidiabetic effects of alpha‐mangostin include enhancing insulin secretion, improving glucose uptake through GLUT receptor upregulation, reducing oxidative stress and inflammation, promoting wound healing, reducing HbA1C, reducing HOMA‐IR index, and decreased mRNA expressions ...

Structure-function relationships of human JmjC oxygenases-demethylases versus hydroxylases.

Current Opinion in Structural Biology, 2016
The Jumonji-C (JmjC) subfamily of 2-oxoglutarate (2OG)-dependent oxygenases are of biomedical interest because of their roles in the regulation of gene expression and protein biosynthesis.

Carotinoid-Oxygenase in Chlorella

Zeitschrift für Naturforschung B, 1958
In Chlorella wurde ein bisher unbekanntes labiles Oxygenasesystem gefunden, das im Dunkeln mit großer Geschwindigkeit Sauerstoff auf Carotinoide überträgt und das durch Licht gehemmt wird. Vgl. dazu O. WARBURG, G. KRIPPAHL und W. SCHRÖDER, Wirkungsspektrum eines Photosynthese-Ferments, diese Z. 10 b, 631 [1955].
