Validity of dietary isothiocyanate intake estimates from a food frequency questionnaire using 24 h urinary isothiocyanate excretion as an objective biomarker: the JPHC-NEXT protocol area.

Eur J Clin Nutr 2021 Jul 6. Epub 2021 Jul 6.

Epidemiology and Prevention Group, Center for Public Health Sciences, National Cancer Center, Tokyo, Japan.

Pharmacognosy Department, Faculty of Pharmacy, Cairo University, Cairo, Egypt; Chemistry Department, School of Sciences & Engineering, The American University in Cairo, New Cairo, Egypt. Electronic address:

Glucosinolate-producing plants have long been recognized for both their distinctive benefits to human nutrition and their resistance traits against pathogens and herbivores. Despite the accumulation of glucosinolates (GLS) in plants is associated with their resistance to various biotic and abiotic stresses, the defensive and biological activities of GLS are commonly conveyed by their metabolic products. In view of this, metabolism is considered the driving factor upon the interactions of GLS-producing plants with other organisms, also influenced by plant and plant attacking or digesting organism characteristics.

Carbon monoxide exposure activates ULK1 via AMPK phosphorylation in murine embryonic fibroblasts.

Int J Vitam Nutr Res 2021 Jun 2:1-10. Epub 2021 Jun 2.

Institute of Biochemistry and Molecular Biology I, Medical Faculty, Heinrich Heine University Düsseldorf, Düsseldorf, Germany.

Carbon monoxide (CO) is endogenously produced upon degradation of heme by heme oxygenases (HOs) and is suggested to act as a gaseous signaling molecule. The expression of HO-1 is triggered by the Nrf2-Keap1 signaling pathway which responds to exogenous stress signals and dietary constituents such as flavonoids and glucosinolates or reactive metabolic intermediates like 4-hydroxynonenal. Endogenous CO affects energy metabolism, regulates the utilization of glucose and addresses CYP450 enzymes. Read More

Sulforaphane Impact on Reactive Oxygen Species (ROS) in Bladder Carcinoma.

Int J Mol Sci 2021 May 31;22(11). Epub 2021 May 31.

Department of Urology, Goethe-University, 60590 Frankfurt am Main, Germany.

Sulforaphane (SFN) is a natural glucosinolate found in cruciferous vegetables that acts as a chemopreventive agent, but its mechanism of action is not clear. Due to antioxidative mechanisms being thought central in preventing cancer progression, SFN could play a role in oxidative processes. Since redox imbalance with increased levels of reactive oxygen species (ROS) is involved in the initiation and progression of bladder cancer, this mechanism might be involved when chemoresistance occurs.
