Gefitinib is a targeted anticancer drug that was developed as an effective clinical therapy for lung cancer. Numerous patients develop gefitinib resistance in response to treatment. Sulforaphane (SFN) is present in cruciferous vegetables, and has been demonstrated to inhibit the malignant growth of various types of cancer cells. To investigate the role of SFN in gefitinib resistance, a gefitini...

BACKGROUND Small fiber neuropathy (SFN) appears to be relatively common in sarcoidosis patients. However, there is no golden standard to establish SFN and diagnostic tests for SFN are not widely available. There is a need for an easy to administer SFN screening instrument for clinical assessment, research or therapeutic trials. The aim of the present study was to develop a screening list to ide...

Background: Cisplatin (CisPt) resistance is one of the major problems for the treatment of osteosarcoma. The natural compound sulforaphane (SFN) are reported to have antitumor activity in many cancers. However, its effect to influence CisPt resistance in osteosarcoma cells has not examined. In this study, we intended to investigate the combined effects of SFN and CisPt in osteosarcoma cells and...

The broccoli isothiocyanate, sulforaphane (SFN), was recently identified as being capable of eliminating highly therapy-resistant pancreatic carcinoma (PC) cells without inducing toxic side effects. While SFN has been shown to stimulate autophagy or 'self-eating', it is unclear whether this catabolic process is a pro- or anti-tumorigenic response. To investigate the role of autophagy in SFN-ind...

Previously, our group reported that sulforaphane (SFN), a naturally occurring chemopreventive agent from cruciferous vegetables, effectively inhibits the proliferation of KB and YD-10B human oral squamous carcinoma cells by causing apoptosis. In this study, treatment of 20 and 40 microM of SFN for 12 h caused a cell cycle arrest in the G(2)/M phase. Cell cycle arrest induced by SFN was associat...

A major component of the anticarcinogenic activity of the dietary chemopreventive agent sulforaphane (SFN) is attributed to its ability to induce expression of phase II detoxification genes containing the antioxidant response element (ARE) within their promoters. Because SFN is a reactive electrophile--readily forming conjugates with glutathione (GSH)--we asked whether expression of glutathione...

d,l-Sulforaphane (SFN), a synthetic analogue of broccoli-derived isomer l-SFN, exerts cytotoxic effects on multiple tumor cell types through different mechanisms and is more potent than the l-isomer at inhibiting cancer growth. However, the means by which SFN impairs glioblastoma (GBM) cells remains poorly understood. In this study, we investigated the anti-cancer effect of SFN in GBM cells and...

SCOPE Sulforaphane (SFN) is an isothiocyanate derived from cruciferous vegetables such as broccoli. The ability of SFN to inhibit histone deacetylase (HDAC) enzymes may be one mechanism by which it acts as a chemoprevention agent. The ability of a chemopreventive agent to specifically cause cytotoxicity in cancer and not normal cells is an important factor in determining its safety and clinical...

BACKGROUND Sulforaphane (SFN), an isothiocyanate found in cruciferous vegetables, is a common dietary component that has histone deacetylase inhibition activity and exciting potential in cancer prevention. The mechanisms by which SFN imparts its chemopreventive properties are of considerable interest and little is known of its preventive potential for breast cancer. PRINCIPAL FINDINGS We foun...

OBJECTIVE Small nerve fiber neuropathy (SFN) often occurs without apparent cause, but no systematic genetic studies have been performed in patients with idiopathic SFN (I-SFN). We sought to identify a genetic basis for I-SFN by screening patients with biopsy-confirmed idiopathic SFN for mutations in the SCN9A gene, encoding voltage-gated sodium channel Na(V)1.7, which is preferentially expresse...
