Objective: Breast cancer is a heterogeneous disease and very common malignancy in women worldwide. The efficacy of chemotherapy as an important part of breast cancer treatment is limited due to its side effects. While pharmaceutical companies are looking for better chemicals, research on traditional medicines that generally have fewer side effects is quite interesting. In this study, apoptosis ...

Background and purpose: Polycaprolactone nanocapsules incorporated with triazole derivatives in the presence absence of selenium nanoparticles were prepared evaluated as antiproli­ferative anticancer agents. using emulsion technique. Experimental approach: The capsules characterized FT-IR, TEM DLS measurements. synthesized triazo­lopyrimidine derivative encap­sulated polycaprolactone was tested...

Present study investigated the possible role of P-glycoprotein in intracellular exposure of active substance (robinin) natural medicine Flaroninum™ and effect robinin on cellular accumulation mitoxantrone either BCRP-overexpressing BCRP-negative cells. Robinin - kaempferol-3-O-b-D-robinoside-7-O-α-L-rhamnopyranoside, has been obtained from over ground parts Astragalus falcatus Lam., growin...

Cancer stem cells are speculated to have the capability of self-renewal and re-establishment of tumor heterogeneity, possibly involved in the potential relapse of cancer. CD44+CD24-/lowESA+ cells have been reported to possess tumorigenic properties, and these biomarkers are thought to be highly expressed in breast cancer stem cells. Cell behavior can be influenced by biomolecular and topographi...

The aim of the present study was to determine whether the combination of two modalities of immunotherapy, targeting two different tumor antigens, may be feasible and non-toxic, yet enhance the killing of a human breast cancer cell line. The first modality was tumor growth factor α-Pseudomonas exotoxin 38 (TGFα-PE38), which specifically targets and kills tumor cells that express the epidermal gr...

Growing evidence indicates that alternative or aberrant premRNA splicing takes place during the development, progression, and metastasis of breast cancer. However, which splicing changes that might contribute directly to tumorigenesis or cancer progression remain to be elucidated. We used splicingsensitive microarrays to detect differences in alternative splicing between two breast cancer cell ...

Nicotine, one of the major components in tobacco, is at high concentrations in the bloodstream of cigarette smokers. However, the mechanisms of how nicotine affects tumor development and whether nicotine is a potential carcinogen for malignancies induced by secondhand smoking are not fully understood yet. Here, we investigate the signaling pathways by which nicotine potentiates tumorigenesis in...
