The renal dopaminergic system plays a significant role in controlling sodium excretion and blood pressure (BP). Overwhelming evidence shows that oxidative stress downregulates renal dopamine receptors (D1R), and antioxidant supplementation protects D1R function. However, the mechanisms for benefits of antioxidants in protecting D1R function are unknown. We investigated the role of nuclear facto...

Alcoholic liver disease (ALD)-related fibrosis results from a variety of mechanisms including the accumulation acetaldehyde, reactive oxygen species, and hepatic overload endogenous lipopolysaccharide (LPS). Alcohol cessation is therapeutic mainstay for patients with all stages ALD, whereas pharmacological strategies have not been established. Sulforaphane, phytochemical found in cruciferous ve...

The present study reports a novel response to sulforaphane, a highly promising anticancer constituent of several edible cruciferous vegetables, in PC-3 and LNCaP human prostate cancer cells involving induction of autophagy. Exposure of PC-3 and LNCaP cells to sulforaphane resulted in several specific features characteristic of autophagy, including appearance of membranous vacuoles in the cytopl...

Organisms exposed to oxidative stress respond by orchestrating a stress response to prevent further damage. Intracellular levels of antioxidant agents increase, and damaged components are removed by autophagy induction. The KEAP1-NRF2 signaling pathway is the main pathway responsible for cell defense against oxidative stress and for maintaining the cellular redox balance at physiological levels...

Persistent paraprotein production in plasma cells necessitates a highly developed rough endoplasmic reticulum (ER) that is unusually susceptible to perturbations in protein synthesis. This biology is believed to account for the exquisite sensitivity of multiple myeloma (MM) to the proteasomal inhibitor bortezomib (BTZ). Despite remarkable response...

According to the cancer stem cell hypothesis the aggressive growth and early metastasis of pancreatic cancer may arise through dysregulation of self-renewal of stem cells in the tissue. Since recent data suggest targeting of cancer stem cells by some dietary agents we studied the effect of quercetin, a major polyphenol and flavonoid commonly detected in many fruits and vegetables. Using in vitr...

Sulforaphane [1-isothiocyanato-4-(methyl-sulfinyl)butane] was recently isolated from one variety of broccoli as the major and very potent inducer of phase 2 detoxication enzymes in murine hepatoma cells in culture. Since phase 2 enzyme induction is often associated with reduced susceptibility of animals and their cells to the toxic and neoplastic effects of carcinogens and other electrophiles, ...

The objective of this study was to evaluate the potential of the structurally related aliphatic isothiocyanates erucin and sulforaphane to modulate the pulmonary carcinogen-metabolising enzyme systems in rat lung, a target organ of their chemopreventive activity. Precision-cut rat lung slices were prepared and incubated for 24 h with a range of concentrations of either erucin or sulforaphane, u...
