Silymarin from milk thistle (Silybum marianum) plant has been reported to show anti-cancer, anti-inflammatory, antioxidant and hepatoprotective effects. For anti-cancer activity, silymarin is known to regulate cell cycle progression through cyclin D1 downregulation. However, the mechanism of silymarin-mediated cyclin D1 downregulation still remains unanswered. The current study was performed to...

Silymarin from milk thistle (Silybum marianum) has been reported to show an anti-cancer activity. In previous study, we reported that silymarin induces cyclin D1 proteasomal degradation through NF-κB-mediated threonine-286 phosphorylation. However, mechanism for the inhibition of Wnt signaling by silymarin still remains unanswered. Thus, we investigated whether silymarin affects Wnt signaling i...

We show that silymarin, a polyphenolic flavonoid isolated from milk thistle (Silybum marianum), inhibits cytokine mixture (CM: TNF-α, IFN-γ, and IL-1β)-induced production of nitric oxide (NO) in the pancreatic beta cell line MIN6N8a. Immunostaining and Western blot analysis showed that silymarin inhibits iNOS gene expression. RT-PCR showed that silymarin inhibits iNOS gene expression in a dose-...

PURPOSE Hepatocellular carcinoma (HCC) is resistant to conventional chemotherapeutics such as doxorubicin. Milk thistle extract, or its active constituent silymarin has been used by cancer patients as an alternative and complementary agent. Telomerase activation is one of the initial events of HCC. In this study, we applied doxorubicin and silymarin for 72 hrs in order to test individual and co...

Objectives It has been demonstrated that polyphenol components such as silymarin and resveratrol have anti-inflammatory properties. Periodontitis is a chronic inflammatory disease that leads to the breakdown of dental supporting tissues and tooth loss. The purpose of this study was to investigate the anti-inflammatory effects of silymarin and resveratrol on lipopolysaccharide (LPS)-induced infl...

Silymarin, a known extract, is used in the treatment of liver diseases with various origins, but its current administration form cannot target the liver because of its poor oral bioavailability. A new type of oral silymarin proliposome aimed at improving silymarin's poor bioavailability and hepatoprotective effects, is introduced in this work. Silymarin-loaded liquid proliposome were prepared u...

We have shown previously that silymarin, a plant flavonoid, inhibits UVB-induced photocarcinogenesis in mice. As UVB-induced immunosuppression has been implicated in the development of skin cancer, we investigated whether silymarin can modulate the effects of UVB radiation on the immune system. Treatment of C3H/HeN mice with topically applied silymarin (0.5 or 1.0 mg/cm(2)) or silibinin, a majo...

Silymarin, a polyphenolic flavonoid antioxidant, is known to have anti-inflammatory, hepatoprotective, and anticarcinogenic effects. In the present study, we report the inhibitory effect of silymarin on nitric oxide production and inducible nitric-oxide synthase (iNOS) gene expression in macrophages. In vivo administration of silymarin attenuated nitric oxide production by peritoneal macrophage...

Staphylococcus aureus is an opportunistic pathogen and remains a common cause of burn wound infections. Different studies have shown that entrapment of plant-derived compounds into liposomes could increase their anti-Staphylococcus aureus activity. Silymarin is the bioactive extract from the known plant Silybum marianum L. The objective of this study was to evaluate efficacy of silymarin in fre...

OBJECTIVE This study aimed to evaluate the efficacy and safety of silymarin on chronic hepatitis C virus- (HCV-) infected patients. METHODS Randomized controlled trials (RCTs) of silymarin in chronic HCV-infected patients up to April 1, 2014 were systematically identified in PubMed, Ovid, Web of Science, and Cochrane Library databases. RESULTS A total of 222 and 167 patients in five RCTs we...
