Background: Poekilocerus pictus (Fabricius 1771), a painted grasshopper, sequesters cardenolides from its food plant, the Apple of Sodom or Aak, Calotropis procera (Aiton) W.T. Aiton (Family-Asclepiadaceae). In our present investigation, we were able to isolate Pseudomonas aeruginosa KRK6 intestine responsible for biotransformation cardenolides. Methods: was grown in methanolic extracts and mod...
Introdution: Targeting vascular endothelial growth factor (VEGF) is considered as a therapeutic goal in solid tumors; especially breast cancer. The use of drugs with natural compounds in the treatment of cancer is increasing because of exerting no adverse effects in normal cells. Crocin, as the main component of saffron, has been proved to have different biological activities on various types o...
Background: Recently, iron oxide nanoparticles have attracted attention in various diagnosis and treatment fields. The aim of the present study was to investigate the cytotoxicity of various concentrations and incubation times of dextran-coated iron oxide nanoparticles (DIONPs) on HeLa and MCF-7 cancerous cell lines. Methods: This in-vitro study was conducted at Pharmaceutical Sciences Researc...
AIM To analyze expression of miRNA in human breast cancer cells, sensitive and resistant to cisplatin and doxorubicin, and to explore possible modification of drug sensitivity via treatment of cells with 5-azacytidine (5-aza), a demethylating agent. MATERIALS AND METHODS The study was performed on wild-type MCF-7 cell line (MCF-7/S) and its two sublines MCF-7/Dox and MCF-7/DDP resistant to do...
Background: Berberine and Nano-curcumin are two herbal medicines with strong anti-cancer effects on tumor cells, but low toxicity on normal cells, when used alone. Breast cancer is known as the most common cancer in women and second deadly one. In this study, we evaluated the cytotoxicity effects of combination Berberine and Nano-curcumin in breast cancer cell line to see whether they have furt...
Antioxidant enzymes are critical in oxidative stress responses. Radioresistant variants isolated from MCF-7 human carcinoma cells following fractionated ionizing radiation (MCF+FIR cells) or overexpression of manganese superoxide dismutase (MCF+SOD cells) demonstrated dose-modifying factors at 10% isosurvival of 1.8 and 2.3, respectively. MCF+FIR and MCF-7 cells (exposed to single-dose radiatio...
Cancer remains to be a major global healthcare burden as 18.1 million new cases and 96 death occurred 2018 on the basis of report from international agency for research cancer Breast is most common diagnosed in women causing highest morbidity. Ipomoea carnea leaf extracts have been used chemotherapeutic agent due their antioxidant, anti-inflammatory, anti-bacterial, anti-tumor effect. The aim s...
Abstract Background Gold nanoparticles (GNPs) have been used to sensitize cancer cells and enhance the absorbed dose delivered such cells. Active targeting can provide specific effect higher uptake of GNPs in tumor cells, while having small on healthy The aim this study was assess possible radiosensitiazation conjugated with AS1411 aptamer (AS1411/GNPs) treated 4 MeV electron beams. Materials m...
a new group of 4-(imidazolylmethyl) quinoline derivatives possessing a methylsulfonyl cox-2 pharmacophore at the para position of the c-2 phenyl ring were designed and synthesized as selective cox-2 inhibitors and in-vitro anti breast cancer agents. in-vitro cox-1 and cox-2 inhibition studies showed that all the compounds were potent and selective inhibitors of the cox-2 isozyme with ic50 value...
cladribine, an analogue of deoxyadenosine, is highly toxic for both non-dividing and proliferating cells and has shown activity in the treatment of several malignancies. therefore, the aim of the present study is to investigate the cytotoxicity effect of cladribine (2-cda) on the breast cancer cell line, mcf-7 (estrogen receptor positive, er+). mtt assay, annexin v-fluorescein/pi and hoechst 33...
