Scorpion venom toxicity is of major concern due to its influence on human activities and public health. We investigated the in-vitro process of cell death caused by two Iranian scorpions Odontobuthus doriae and Bothutus salceyi venom on human cell lines. The aim of this study was to provide further information about triggering cell death and suggestion of methods for the elimination of unwanted...
Introduction & Objective: Hepatocellular carcinoma (HCC, also called malignant hepatoma) is a primary malignancy (cancer) of the liver. Most cases of HCC are secondary to either a viral hepatitic infection (hepatitis B or C) or cirrhosis (alcoholism being the most common cause of hepatic cirrhosis. Recently, the biological activities of zingiber officieale plants have been reported as possess...
OBJECTIVES Preclinical evaluation of the anti-neoplastic activity of an insulin-like growth factor I receptor (IGF-IR) kinase inhibitor in ovarian cancer. METHODS The OVCAR-3 and OVCAR-4 cell lines were investigated under serum-free tissue culture conditions. IGF-I and IGF-II production were evaluated by standard ELISA and immunohistochemistry. IGF-IR expression and protein levels were evalua...
PURPOSE Hypermethylation of CpG islands in the promoters of selected genes is a common feature of neoplasia. Aberrant methylation of cyclin D2 has been observed in several cancers. We investigated the methylation of cyclin D2 in aging and pancreatic neoplastic development, and the utility of cyclin D2 methylation as a marker of pancreatic adenocarcinoma. EXPERIMENTAL DESIGN Methylation-specif...
Background and purpose: Penicilliums have high diversity among fungi species and some of them are found to be very useful. Some studies have evaluated their antimicrobial and cytotoxic effects. Penicillium citrinum is a genus of the penicilliums that produces mycotoxin citrinin. Therefore, it is worthy to assess its cytotoxic effect. Materials and methods: The DNA of the fungus obtained from t...

objective: thymoquinone (tq), as the main component of nigella sativa plant, shows anticancer properties. this study was aimed to evaluate the combined effect of tq and tamoxifen (tam) on viability and apoptosis of human breast cancer cell lines. materials and methods: in this experimental study, estrogen positive mcf-7 and estrogen negative mda-mb-231 human breast cancer cell lines were induce...
Loss of expression of the FHIT tumor suppressor gene is common in epithelial malignancies such as lung, kidney, esophageal, gastric, and cervical cancers. To assess the role of FHIT in acute leukemias, we examined 18 primary acute lymphoblastic leukemias (ALLs), 8 ALL-derived cell lines, 7 cell lines from other hematological malignancies, 14 lymphoblastoid cell lines, and 5 peripheral blood lym...
This study focuses on characterizing the genetic and biological alterations associated with squamous cell carcinoma development. Normal human epidermal keratinocytes (HEKs), cells isolated from a preneoplastic lesion (IEC-1), and two neoplastic cell lines, SCC-25 and COLO-16, were grown as raft cultures, and their gene expression profiles were screened using cDNA arrays. Our data indicated that...
