Immunohistochemical staining utilizing a peroxidase-antiperoxidase (PAP) technique for keratin, carcinoembryonic antigen (CEA), human chorionic gonadotropin (HCG) and alpha-fetoprotein (AFP) was performed on paraffin sections from 72 cases of lung cancer obtained at autopsy. Positive reaction was shown in 44% of the cases for keratin, 77% for CEA, and 58% for HCG. AFP was positive in only one c...
Dihydroactinidiolide (1) and a mixture of sterols [campesterol (2), stigmasterol (3) and beta-sitosterol (4)], together with the previously isolated individual compounds beta-sitosterol (4), 2,4-di-tert-butylphenol (5), alpha-tocopherol (6), phytol (7) were isolated from the active ethyl acetate fraction of Pereskia bleo (Kunth) DC. (Cactaceae) leaves. Cytotoxic activities of the above mentione...
The synthesis of 4-methoxycarbonyl-3-methylisoquinolinequinone (1) and a variety of its substitution products with amino-, alkylamino and halogen groups on the quinone nucleus is reported. The series of 6-, 7- and 6,7-subtituted isoquinolinequinones were evaluated in vitro for their cytotoxic activity using the MTT colorimetric method. All the newly synthesized compounds showed moderate to high...
Background and purpose: Several studies have been carried out on re-cut and de-stained sections regarding prostate biopsies and cytologic specimens of squamous cell carcinoma. However, few studies on lung biopsy are done. Due to small size of lung biopsies and for the prevention of lung rebiopsy, in this study P63 staining intensity between re-cut and de-stained slides of patients, specimens ...
Background: 4-Aryl-4H-chromenes are novel anticancer agents which induce apoptosis in cancer cells. These compounds were found to induce apoptosis by targeting the tubulin/microtubule system in cell proliferation process. The aim of this study was to report cyototoxic and apoptosis inducing activities of a new series of synthesized 4-aryl-4H-chromenes compounds. Methods: The in vitro cytotoxic...
conclusions according to the low prevalence of hcmv in oscc, it seems that this virus plays a minor role in this kind of cancer at least in southeast of iran. more comprehensive studies are needed to investigate the oncomodulatory effect of this virus on oscc. results the mean age of the patients (66.7% female and 33.3% male) was 58.6 years. only three cases (6.3%) of the grade i, oscc biopsies...
BACKGROUND Glypican-3 (GPC3) is a cell surface-bound proteoglycan which has been identified as a potential biomarker candidate in hepatocellular carcinoma, lung carcinoma, severe pneumonia, and acute respiratory distress syndrome (ARDS). The aim of our review is to evaluate whether GPC3 has utility as a disease-specific biomarker, to discuss the potential involvement of GPC3 in cell biology, an...
BACKGROUND A disintegrin and metalloproteinase 28 (ADAM28) is implicated in tumor growth and metastasis in human breast and non-small cell lung carcinomas. We explored the mechanism of ADAM28-mediated metastasis by searching for new substrates of ADAM28. METHODS We used a yeast two-hybrid system to screen the human lung cDNA library for ADAM28-binding proteins and identified von Willebrand fa...
Two human small cell lung carcinoma cell lines, NCI-H69 and NCI-H128, were used as alternating sources of immunogen to generate monoclonal antibodies to small cell lung carcinoma-associated antigens. BALB/c mice were sensitized with seven injections of live tumor cells, four with NCI-H69 cells and three with NCI-H128 cells. Somatic cell hybridization was performed by fusion of the immune murine...
PURPOSE Lung cancer is a biologically diverse disease and relevant models reflecting its diversity would facilitate the improvement of existing therapies. With a view to establishing such models, we developed and evaluated xenografts of a variety of human lung cancers. EXPERIMENTAL DESIGN Using nonobese diabetic/severe combined immunodeficiency mice, subrenal capsule xenografts were generated...
