Lung cancer is still a very severe disease which has a low survival rate due to local invasion and metastasis potentials in spite of many clinical challenges using anti-cancer drugs. Rho family small GTPases play pivotal roles in cell invasion and metastasis during carcinogenesis. In this study, we explored the inhibitory effect of adenoviral vector encoding dominant negative mutants of Rac, Rh...
Human bronchioloalveolar carcinoma (BAC) is a lung cancer, morphologically similar to an endemic contagious lung neoplasm of sheep called sheep pulmonary adenomatosis (SPA) or jaagsiekte. SPA is caused by an exogenous type B/D retrovirus (jaagsiekte sheep retrovirus (JSRV)), which prompted the present study to obtain evidence of a retrovirus in BAC. A panel of 249 human lung tumours, 21 nontumo...
The development of improved animal models for biological and preclinical studies of human lung cancer is important because lung cancer is the leading cause of cancer death in the United States. To determine whether the Rowett nude rat could serve as an orthotopic (organ-specific) model of this disease, nude rats (CR: NIH-RNU), with and without 500 rads of prior gamma-irradiation, were implanted...
this paper presents four cases of abnormal soft tissue activity in the bone scan of patients with different lesions (lung inflammatory pseudotumor, pulmonary fibrosis, pulmonary metastatic osteosarcoma and metastatic hepatic carcinoma of colon).
A Gram-positive, rod-shaped bacterium, designated as S-1, was isolated from a marine sediment sample collected from South China Sea. Phylogenetic analysis based on 16S rRNA gene sequence showed that S-1 belongs to the genus Brevibacillus. A novel cytotoxic peptide was isolated from the fermentation broth of the marine-derived bacterium Brevibacillus sp. S-1, using ion-exchange chromatography an...
Human small cell lung carcinoma (SCLC) cells have been shown to contain significant levels of a bombesin-immunoreactive peptide. The 27-amino acid peptide, gastrin releasing peptide (GRP), has recently been shown to be responsible for the bombesin-like immunoreactivity found in SCLC cells. Among four lung cancer cell lines examined in vitro, GRP exhibited mitogenic activity for two SCLC subtype...
A general transcription factor IID which binds to the TATA box promoter element on RNA polymerase II genes regulates and initiates eukaryotic mRNA synthesis. A quantitative polymerase chain reaction procedure was developed and the human transcription factor IID (hTFIID) transcript was measured in normal human tissues, lung carcinomas, lung carcinoma cell lines, and breast carcinomas. In some no...
A general transcription factor IID which binds to the TATA box promoter element on RNA polymerase II genes regulates and initiates eukaryotic mRNA synthesis. A quantitative polymerase chain reaction procedure was developed and the human transcription factor IID (h II III)) transcript was measured in normal human tissues, lung carci nomas, lung carcinoma cell lines, and breast carcinomas. In som...
The expression pattern of Eand P-cadherin in human carcinomas has been reported by many laboratories. However, little is known about the involvement of other cadherin types in human carcinomas. cDNA clones for a cadherin molecule were isolated from a cDNA library of human hepatocellular carcinoma cells which lacked Eand P-cadherin expression but exhibited cell aggregation activity mediated by a...
BACKGROUND Pyrazoles, thiazoles and 1,3,4-thiadiazoles have been reported to possess various pharmacological activities. RESULTS An efficient and a novel approach for the synthesis of some novel pyrazole based-azoles are described via multi-component reaction under controlled microwave heating conditions. The structures of the synthesized compounds were assigned on the basis of elemental anal...
