The aim of this current study was to examine the significance of CD44 expression in mediating cancer cell adhesion to human bone marrow endothelial cell(s) (hBMEC). Differential CD44 expression on two metastatic prostate cancer cell lines, PC3 (CD44 ve) and DU145 (CD44 ve) and four breast cancer cell lines was confirmed by immunoblotting and immunocytochemistry. In cell adhesion assays, PC3 but...
The aim of this current study was to examine the significance of CD44 expression in mediating cancer cell adhesion to human bone marrow endothelial cell(s) (hBMEC). Differential CD44 expression on two metastatic prostate cancer cell lines, PC3 (CD44 +ve) and DU145 (CD44 -ve) and four breast cancer cell lines was confirmed by immunoblotting and immunocytochemistry. In cell adhesion assays, PC3 b...
Compounds containing triazene ring structure are cytotoxic agents and clinically used as antitumor alkylating agents. In this study, a series of triazene derivatives holding alkyl and aryl moieties were synthesized and proved to be potent cytotoxic agents in-vitro particularly against eight cancer cell lines (PC3, HT29, Hela, HL60, Jurkat, K562, MCF7, HepG2) and a non-cancerous cell line (HUVEC...
Cisplatin is a common chemotherapeutic agent that used for treatment of many solid cancers. Rapid identification of chemotherapy resistance is very important and may lead to effective treatment plan. Spectroscopy techniques, such as infrared spectroscopy, which are sensitive to biochemical composition of samples, have shown potentials to discriminate tissues. Developing in Fourier transform inf...
The aim of this study was to evaluate and compare the cytotoxicity induced by two resin-based sealers, 2Seal and AH Plus, in two osteoblast-like cell lines, MG-63 and Saos-2. Using sterile discs of both sealers in complete media, 24- and 72-h extracts were prepared. The extracts were exchanged with Saos-2 or MG-63 cell culture media at 75% confluence, and after 24 h incubation, cell viability t...
Objective Articular cartilage as an avascular skeletal tissue possesses limited capacity to heal. On the other hand, it is believed that the regeneration capacity of each tissue is largely related to its stem cell contents. Little is known about the presence of mesenchymal stem cells in articular cartilage tissue. This subject is investigated in the present study. Materials and Methods Artic...
the role of antioxidants in prevention and treatment of cancers have been reported by several studies. in our investigation we studied the effects of ascorbic acid, ?-tocopherol, and sodium selenite on proliferation of two breast cancer cell lines: t47d (estrogen-receptor positive) and mda-mb-231 (estrogen-receptor negative). we also used 17-?-estradiol as positive control for proliferation of ...
BACKGROUND Several cell lines and primary cultures benefit from the use of positively charged extracellular matrix proteins or polymers that enhance their ability to attach to culture plates. Polyethyleneimine is a positively charged polymer that has gained recent attention as a transfection reagent. A less known use of this cationic polymer as an attachment factor was explored with several cel...
The reactivity of a panel of antiganglioside monoclonal antibodies with a number of melanoma cell lines having different ganglioside composition profiles was studied. One cell line synthesized only GM3, one produced both GM3 and GD2, 2 had GM3 and GD3 as their major gangliosides, and 2 others synthesized approximately equal amounts of GM3, GM2, GD3, and GD2 gangliosides. Antibody reactivity wit...
background: rapidly increasing possibilities of exposure to environmental extremely low-frequency electromagnetic fields (elf-emf) have become a topic of worldwide investigation. epidemiological and laboratory studies suggest that exposure to elf-emf may increase cancer risk therefore assessment of chromosomal damage in various cell lines might be of predictive value for future risk estimation....
