INTRODUCTION Rheumatoid arthritis (RA) is characterized by progressive inflammation associated with rampantly proliferating synoviocytes and joint destruction due to oxidative stress. Recently, we described nuclear factor erythroid 2-related factor 2 (Nrf2) as a major requirement for limiting cartilage destruction. NF-κB and AP-1 are the main transcription factors triggering the inflammatory pr...

PURPOSE Protecting the lens against oxidative stress is of great importance in delaying the onset of cataract. Isothiocyanates, such as sulforaphane (SFN), are proposed to provide cytoprotection against oxidative stress. We therefore tested the ability of SFN to perform this role in lens cells and establish its ability to delay the onset of cataract. METHODS The human lens epithelial cell lin...

OBJECTIVE We explored the inhibitory effect of sulphoraphane (SFN), a potent inducer of Phase 2 enzymes, on cytokine-induced prostaglandin E(2) (PGE2) and nitric oxide (NO) production and cartilage degradation in articular chondrocytes. The regulatory mechanism of SFN on nuclear factor (NF)-κB was investigated. METHODS Chondrocytes were obtained from patients with knee OA. Chondrocytes were s...

Di-N-butylphthalate (DBP) is one of the most common endocrine-disrupting chemicals which can disrupt human endocrine system, especially in the male reproductive system. Here, this study was aimed to determine whether sulforaphane (SFN) could protect against testicular oxidative stress injury induced by DBP in male mice offsprings. Wild-type (Nrf2+/+) and Nrf2-deficient (Nrf2-/-) timed-pregnant ...

Marburg virus, the Kaposi's sarcoma-associated herpesvirus (KSHV) and Dengue virus all activate, and benefit from, expression of the transcription regulator nuclear erythroid 2-related factor 2 (Nrf2). The impact of Nrf2 activation on human immunodeficiency virus (HIV) infection has not been tested. Sulforaphane (SFN), produced in cruciferous vegetables after mechanical damage, mobilizes Nrf2 t...

Advanced-stage ovarian cancer is characterized by high mortality due to development of resistance to conventional chemotherapy. Novel compounds that can enhance the efficacy of conventional chemotherapy in ovarian cancer may overcome this drug resistance. Consumption of green tea (epigallocatechin gallate, EGCG) and cruciferous vegetables (sulforaphane, SFN) is inversely associated with occurre...

Sulforaphane [SFN: 1-isothiocyanato-4-(methylsulfinyl)butane] belongs to the isothiocyanate class of phytochemicals. Glucoraphanin, a glucosinolate precursor of SFN, is a glucosinolate found in cruciferous vegetables such as broccoli, cabbage, cauliflower, and kale. All glucosinolates are composed of a basic structure consisting of a β-D-thioglucose group, a sulfonated oxime group, and an amino...

The survival benefits of patients with glioblastoma (GBM) remain unsatisfactory due to the intrinsic or acquired resistance to temozolomide (TMZ). We elucidated the mechanisms of sulforaphane (SFN) reverse TMZ resistance in TMZ-inducing cell lines by inhibiting nuclear factor-κB (NF-κB) transcriptional activity. TMZ-resistant cell lines (U87-R and U373-R) were generated by stepwise (6 months) e...

BACKGROUND Mammalian forkhead members of the class O (FOXO) transcription factors, including FOXO1, FOXO3a, and FOXO4, are implicated in the regulation of several biological processes, including the stress resistance, metabolism, cell cycle, apoptosis and DNA repair. The objectives of this study were to examine the molecular mechanisms by which FOXO transcription factors induced cell cycle arre...

Effects of different concentrations [0, 1, 5, 10, 20 and 40 mgL-1] of Fe3O4 and CuO nano-particles (nFe3O4 and nCuO) were investigated on sulforaphane (SFN) production level in 7-day-old seedlings of Lepidium draba at different time intervals (8 and 16 hrs). According to the results, the influence of the particles on SFN contentdepends on nano-particle (NP) concentrations, time of treatment as ...
