Abstract:

Paclitaxel is the one of the most common chemotherapeutic drugs used for the treatment of prostate cancer. However, its current clinical utility has been limited due to numerous serious side effects and drug resistance. Noscapine is an antitussive opium alkaloid that showed antitumor activity against a variety of cancer while has not exhibited severe side effects. This study investigates the anticancer activity of noscapine in combination with paclitaxel against two LNCaP and PC-3 human prostate cancer cell lines. LNCaP and PC-3 cells were treated with noscapine or paclitaxel or combination. Cell viability was determined using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) test. Apoptosis was assessed by acridine orange/ ethidium bromide (AO/EB) staining. The mRNA expression of Bax, Bcl-2, AR and PSA in the cellular response to treatments was investigated. MTT assay indicated the combination treatment of paclitaxel and noscapine significantly decreased viability compared to single-agent treatment and control groups. The results obtained with AO/EB double staining showed increased percentages of apoptotic cells in the presence of the combination of paclitaxel and noscapine. Furthermore, combinational treatment of paclitaxel and noscapine showed significant decrease in the mRNA expression of B-cell CLL/Lymphoma (Bcl-2) and increase in the mRNA expression of Bcl-2-associated X protein (Bax(, and Bax/Bcl-2 ratio in LNCaP and PC-3 cells (p

Anticancer Effects of Deoxypodophyllotoxin and Juniperus communis L. on Prostate Cancer Cell Lines

Background and purpose: In this study, the effects of a mixture of deoxypodophyllotoxin/DPT and Juniperus communis L. on apoptosis and cellular inhibition were evaluated. Also, their cytotoxicity effects on prostate cancer cells (PC3 and DU145) and normal cells (HGFs), their anti-inflammatory effects, oxidation properties, and their effects on the expression of androgen receptors (AR) and clust...

Synergistic Effects of NDRG2 Overexpression and Radiotherapy on Cell Death of Human Prostate LNCaP Cells

Background: Radiation therapy is among the most conventional cancer therapeutic modalities with effective local tumor control. However, due to the development of radio-resistance, tumor recurrence and metastasis often occur following radiation therapy. In recent years, combination of radiotherapy and gene therapy has been suggested to overcome this problem. The aim of the current study was to e...

Evaluation of miR-34a Effect on CCND1 mRNA Level and Sensitization of Breast Cancer Cell Lines to Paclitaxel

Background: A growing body of literature has revealed the effective role of miR-34a, as a tumor suppressor and regulator of expression of multiple targets in tumorigenesis and cancer progression. This study aimed at evaluating the potential effects of miR-34a alone or in combination with paclitaxel on breast cancer cells. Methods: After miR-34a transduction by lentiviral vectors in two MCF-7 an...
