Tumor necrosis factor (TNF)-alpha is one of the pro-inflammatory cytokines highly expressed in Helicobacter pylori that inhibits gastric acid secretion. In this study we determined the effect of silibinin on TNF-alpha-induced MMP-9 expression in gastric cancer cell lines. MMP-9 mRNA and protein expression was dose-dependently increased by TNF-alpha in SNU216 and SNU668 gastric cancer cells. On ...
Transcription factor signal transducer and activator of transcription (Stat)-3 is activated constitutively in prostate cancer (PCA) suggesting that its disruption could be an effective approach to control this malignancy. Here we assessed whether silibinin, a flavanone from Silybum marianum with proven anticancer efficacy in various cancer models, inhibits Stat3 activation in DU145 cells, and i...
Apoptosis Induction by OTA and TNF-α in Cultured Primary Rat Hepatocytes and Prevention by Silibinin
In cultures of primary rat hepatocytes, apoptosis occurred after application of 20 ng/mL tumor necrosis factor alpha (TNF-α). However, this was only in the presence of 200 ng/mL of the transcriptional inhibitor actinomycin D (ActD). This toxic effect was completely prevented in the presence of 25 µg/mL soluble TNF-α receptor I (sTNFR I) in the supernatant of hepatocyte cell cultures. Apoptosi...
More than 90% of all fatal mushroom poisonings worldwide are due to amatoxin containing species that grow abundantly in Europe, South Asia, and the Indian subcontinent. Many cases have also been reported in North America. Initial symptoms of abdominal cramps, vomiting, and a severe cholera-like diarrhea generally do not manifest until at least six to eight hours following ingestion and can be f...
Beneficial Effects of Silibinin Against Kainic Acid-induced Neurotoxicity in the Hippocampus in vivo
Silibinin, an active constituent of silymarin extracted from milk thistle, has been previously reported to confer protection to the adult brain against neurodegeneration. However, its effects against epileptic seizures have not been examined yet. In order to investigate the effects of silibinin against epileptic seizures, we used a relevant mouse model in which seizures are manifested as status...
OBJECTIVE To evaluate the effects of silibinin hemisuccinate on the normal intraocular pressure (IOP) in rabbits. METHODS This study took place in the Department of Pharmacology and Toxicology, College of Pharmacy, University of Baghdad during the period from January to June 2005. Twenty-five New Zealand white rabbits weighing 1.5-2.5 kg were used in this study. The effects of corneal instill...
Herein, we have evaluated for the first time the chemopreventive efficacy of silibinin on prostate cancer (PCa) metabolism in the transgenic adenocarcinoma of the mouse prostate (TRAMP) model utilizing quantitative high-resolution proton nuclear magnetic resonance spectroscopy (HNMRS) metabolomics. Prostate tissues were obtained from 4 week-old mice which were fed control or 1% silibinin-supple...
The flavonoid silymarin and one its structural components, silibinin, have been well characterized as hepato-protective substances. However, little is known about the biochemical mechanisms of action of these substances. This review deals with recent investigations to elucidate the molecular action of the flavonoid. Three levels of action have been proposed for silymarin in experimental animals...
Our previous research demonstrated that hepatic-protectant silibinin induced autophagy in human fibro-sarcoma HT1080 cells through reactive oxygen species (ROS) pathway. Pifithrin-α (PFT-α), a specific inhibitor of p53, reduced autophagy and reversed silibinin's growth-inhibitory effect; besides, PFT-α decreased the activation of caspase-3, a crucial executor of apoptosis. Silibinin upregulated...
OBJECTIVES The efficacy of current hepatitis C virus (HCV) triple therapy, including a protease inhibitor, is limited in HIV/HCV-coinfected patients with advanced liver fibrosis and nonresponse to previous peginterferon-ribavirin. These patients have a low chance (only 30%) of achieving a sustained virological response (SVR) during triple therapy and cannot wait for next-generation anti-HCV dru...
