Although epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKI) produce an initially dramatic response in lung cancer patients harboring a mutation in the EGFR gene, development of acquired resistance is almost inevitable. A secondary mutation of threonine 790 (T790M) is associated with approximately half of the cases of acquired resistance. This study investigated whether the a...

OBJECTIVES Hepatitis C-virus-persistence after orthotopic liver transplant leads to reduced patient and graft survival compared to other indications. Current interferon-based antiviral therapy of hepatitis C-virus-infection posttransplant provides a sustained response rate of 30% to 40%. This study, performed in an hepatitis C-virus-reinfected liver transplant population, examines the antiviral...

The male reproductive system is vulnerable to oxidative stress, which linked several disorders. Silibinin, a natural polyphenolic flavonoid, possesses antioxidant, anti-inflammation and anticancer properties. Considering silibinin's wide range of biological metabolic roles (silibinin) plays, the current study was conducted evaluate biochemical, histological, immunohistochemical morphometric cha...

Here, we assessed the protective effect of silibinin on UVB-induced skin carcinogenesis in SKH-1 hairless mice. Topical application of silibinin before or immediately after UVB exposure or its dietary feeding resulted in a strong protection against photocarcinogenesis, in terms of tumor multiplicity (60–66%; P < 0.001), tumor volume per mouse (93–97%; P < 0.001) and tumor volume per tumor (80–9...

BACKGROUND Drug resistance and tumor metastasis are the main causes of treatment failure and mortality in cancer patients. Silibinin, a naturally occurring flavanone, has been shown to be a potent sensitizer for apoptosis induced by a variety of anticancer drugs. In this study, whether silibinin could overcome chemoresistance and reduce the invasiveness of A2780/taxol cells was investigated. ...

Silibinin, a natural flavonoid antioxidant isolated from extracts of the milk thistle herb, has recently been identified as having anti-hepatotoxic and anticancer properties. In this paper, we investigated the effects of silibinin on behavior and neuroplasticity in mice subjected to chronic unpredictable mild stress (CUMS). After 5 consecutive weeks of CUMS, the mice were treated with silibinin...

Nicotinamide adenine dinucleotide (NAD⁺) homeostasis is emerging as a key player in the pathogenesis of non-alcoholic fatty liver disease (NAFLD) and is tightly linked to the SIRT1/5'-AMP-activated protein kinase (AMPK) pathway. Silibinin, the main component of silymarin, has been proposed as a nutraceutical for the treatment of NAFLD. In this study, we aimed to identify whether silibinin may i...

The flavolignan silibinin was studied for its ability to restore drug sensitivity to EGFR-mutant NSCLC xenografts with epithelial-to-mesenchymal transition (EMT)-driven resistance to erlotinib. As a single agent, silibinin significantly decreased the tumor volumes of erlotinib-refractory NSCLC xenografts by approximately 50%. Furthermore, the complete abrogation of tumor growth was observed wit...

Silibinin is a composition of the silymarin group as a hepatoprotective agent, and it exhibits various biological activities, including antibacterial activity. In this study, the antibacterial activities of silibinin were investigated in combination with two antimicrobial agents against oral bacteria. Silibinin was determined with MIC and MBC values ranging from 0.1 to 3.2 and 0.2 to 6.4  μg/mL...

Silibinin is a natural flavonoid antioxidant with anti-hepatotoxic properties and pleiotropic anticancer capabilities. We tested the hypothesis that silibinin inhibits cellular invasiveness by down-regulating the focal adhesion kinase (FAK) and extracellular signal-regulated protein kinase (ERK)-dependent c-Jun/activator protein-1 (AP-1) induction, which leads to inhibition of urokinase-type pl...
