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...

quinazolinone ring system is renown because of its wide spectrum of pharmacological activities due to various substitutions on this ring system. in this study, the minimum inhibitory concentration of the synthesized compounds in our laboratory was determined by micro dilution alamar blue ® assay against six strains of bacteria (three gram-positive and three gram-negative) and three strains of f...

two set of 2-aryl-5,6-dihydropyrrolo[2,1-a] isoquinolines were designed and synthesized to evaluate their biological activities as topoisomerase inhibitors. cytotoxic activity of the synthesized compounds 4a-e and 7a-d was assessed against several human cancer cell lines, including mcf-7 (breast cancer cell), hepg2 (liver hepatocellular cells), a549 (adenocarcinomic human alveolar basal epithel...

The objective of this study was to evaluate the cytotoxicity potential of aqueous extracts of Nepeta cataria, Fumaria indica, Borago officinalis, Adiantum capillus, Levandula stoeches on HeLa cell line. Leaves of plants were washed with distilled water, dried in shade, grinded to fine powder and stored in airtight container at room temperature in the dark until used. The powdered samples were s...

The HeLa cell line is one of the most popular cell lines in biomedical research, despite its well-known chromosomal instability. We compared the genomic and transcriptomic profiles of 4 different HeLa batches and showed that the gain and loss of genomic material varies widely between batches, drastically affecting basal gene expression. Moreover, different pathways were activated in response to...

cervical cancer is the most common gynecologic cancer and the second most common cancer in women worldwide. herbal preparations are used to treat cancer for centuries. the aim of this study was investigate the cytotoxic effects of the methanol extract of citrullus colocynthis and volatile oils of iranian c. medica on hela cell line. after preparation extract and volatile oils, different concent...

The interactions of group B streptococci (GBS) with HeLa cells (an epithelial cell line) and MRC-5 cells (a fibroblastic cell line) were explored. A host-cell invasion assay using GBS strains from all serotypes revealed that GBS invaded HeLa cells to a greater extent than MRC-5 cells. One strain, a serotype V (NCS13), was highly invasive against HeLa cells. All strains were poorly invasive agai...

background: prostate cancer is one of the leading causes of cancer deaths among men. new gene expressed in prostate (ngep), is a prostate-specific gene expressed only in normal prostate and prostate cancer tissue. because of its selective expression in prostate cancer cell surface, ngep is a potential immunotherapeutic target. to target the ngep in prostate cancer, it is essential to investigat...
