The Antarctic is a potentially important library of microbial resources and new bioactive substances. In this study, microorganisms were isolated from surface water samples collected from different sites of the Antarctic. 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay-based cytotoxicity-tracking method was used to identify Antarctic marine microorganism resources f...
background cervical cancer is the leading cause of death from cancer in under-developed countries. human papilloma virus (hpv) 16 and 18 are the most prevalent types associated with carcinogenesis in the cervix. conventional polymerase chain reaction (pcr), type-specific and consensus primer-based pcr followed by sequencing, restriction fragment length polymorphism (rflp) or hybridization by sp...
human papillomavirus (hpv) has also been suggested as an etiology of esophageal squamous cell carcinoma (scc). the aim of this study was to investigate the prevalence of hpv infection in esophageal sccs in our region with strict contamination control to prevent false positive results. thirty cases of esophageal squamous cell carcinomas were chosen by simple random selection in a period of two y...
Lung cancer, primarily associated with tobacco use, is the leading cause of cancer morbidity and mortality in the United States. Squamous cell carcinoma (SCC) is one of the four major histological types of lung cancer. Although there are several established models for lung adenoma and adenocarcinomas, there is no well-established mouse model for lung SCC. We treated eight different inbred strai...
A family of human transforming genes, previously shown to share homology with the ras family of viral oncogenes, maps to three different human chromosomes. A well-characterized mouse-human hybrid cell panel, combined with Southern blotting, was used in this study. The transforming gene of the T24 bladder carcinoma cell line maps to human chromosome 11. An oncogene isolated from the lung carcino...
background : the ability to accept illness is a major issue in the life of a person with cancer. acceptance of disease is simultaneously conducted at two levels: the emotional and cognitive-behavioral one. it is consequential to cancer af-fecting numerous aspects of patient's life, i.e. the physical, mental, social and the spiritual area. the aim of the study was to verify the influence of soci...
Keratinocyte growth factor (KGF)/fibroblast growth factor-7 (FGF-7), a mesenchymal cell-derived paracrine growth factor that specifically stimulates epithelial cell proliferation, has been implicated in the repair of lung tissue. The present study was designed to determine the expression and role of KGF and its receptor (KGFR) in human lung cancer tissues, particularly in relation to cancer cel...
BACKGROUND/AIMS Oxidative stress results in protein oxidation and is implicated in carcinogenesis. Sulfiredoxin (Srx) is responsible for the enzymatic reversal of inactivated peroxiredoxin (Prx). Nuclear factor E2-related factor 2 (Nrf2) binds to antioxidant responsive elements and upregulates the expression of Srx and Prx during oxidative stress. We aimed to elucidate the biological functions ...
Epidemiological studies indicate that the use of aspirin decreases incidence of and mortality from gastrointestinal cancers. A major target of aspirin and other nonsteroid anti-inflammatory drugs is cyclooxygenase (Cox), the rate-limiting enzyme in the conversion of arachidonic acid to prostanoids. Two Cox genes have been cloned (Cox-1 and Cox-2), of which Cox-2 has recently been found to be ex...
We have examined a panel of human lung cancer cell lines for amplification and expression of the c-myc, N-myc, and c-myb oncogenes. The cell lines analyzed represent various histopathological types of lung cancer: small cell carcinoma with neuroen docrine properties; squamous cell carcinoma with epithelial mark ers; and large cell carcinoma with a mixed neuroendocrineepithelial phenotype. Two o...
