KAI1/CD82, a tetraspanin membrane protein functions as a metastasis suppressor in many types of human cancers and has been shown to regulate cell adhesion properties. In the present study, we investigated the underlying mechanism of KAI1/CD82-mediated changes in cell adhesion to the extracellular matrix using human prostate cancer cells. We found that high KAI1/CD82 expression attenuated short-...

curcumin (cur) is the active curcuminoid with many physiological, biochemical, and pharmacological properties. solubility and stability of cur is the limiting factors for realizing its therapeutic potential. bovine β-casein is an abundant milk protein that is highly amphiphilic and self-assembles into stable micellar nanoparticles in aqueous solution. β-casein nanoparticle can solubilize cur mo...

Leucine-rich repeat-containing G protein-coupled receptor 5 (LGR5), a seven transmembrane receptor known as a potential stem cell marker for intestinal crypts and hair follicles, has recently been found to be overexpressed in some types of human cancers. However, the role of LGR5 in cervical cancer remains unclear. In this study, the expression of LGR5 gradually increases from normal cervix to ...

Objective To investigate β-catenin-mediated bacterial elimination during Pseudomonas aeruginosa infection of macrophage-like RAW264.7 cells. Methods Cell viability and catenin beta 1 ( CTNNB1) expression in RAW264.7 cells following P. aeruginosa infection versus uninfected cells, were detected by cell counting kit-8 assay and β-catenin Western blots. RAW264.7 cells with CTNNB1 overexpression we...

Background: β-Hematin (Hemozoin) was synthised inside human erythrocyte by malaria parasite. The parasite avoids the toxic effects by polymerizing heme molecules into insoluble crystalline β-Hematin. C. botrys and A. annua used for the treatment of diseases like malaria, hepatitis, cancers, and inflammations. Objective: Determine of antimalarial and anti-protozoa effects of A. anuuae and C. bo...

Hepatocellular carcinoma (HCC) is the most common liver cancer, with a very poor prognosis. There is an urgent need for an effective therapy for HCC. Ginsenoside Rh2 (GRh2) has been shown to significantly inhibit growth of some types of cancer, whereas its effects on HCC have not been examined. Here, we treated human HCC cells with different doses of GRh2, and found that GRh2 dose-dependently r...

The formation of hemozoin (malaria pigment) has been proposed as an ideal drug target for antimalarial screening programs. In this study, we used an improved, cost-effective and high-throughput spectrophotometric assay to screen plant extracts for finding novel antimalarial plant sources. Fifteen extracts with different polarity from three Iranian Artemisia species, A. ciniformis, A. biennis an...

An improved production and purification method for Alzheimer's disease related methionine-modified amyloid-β 1-40 and 1-42 peptides is proposed, taking advantage of the formation of inclusion body in Escherichia coli. A Thioflavin-S assay was set-up to evaluate inclusion body formation during growth and optimize culture conditions for amyloid-β peptides production. A simple and fast purificatio...

Objective(s): In this study a series of novel colchicine-like β-acetamidoketones was designed and synthesized as potential tubulin inhibitorsMaterials and Methods: The cytotoxicity of the novel synthesized β-acetamidoketones was assessed against two cancerous cell lines including MCF-7 (human breast cancer cells) and A549 (adenocarcinomi...

Wnt/β-catenin signaling plays a major role in embryonic development and adult stem cell maintenance. Reduced activation of the Wnt/β-catenin pathway underlies neurodegenerative disorders and aberrations in bone formation. Screening of a small molecule compound library with a β-galactosidase fragment complementation assay measuring β-catenin nuclear entry revealed bona fide activators of β-caten...
