A panel of seven monoclonal antiepithelial antibodies of different specificities, including anticytokeratin, human milk fat globule membrane, C, and carcinoembryonic antigen (CEA) were used with the alkaline phosphatase-antialkaline phosphatase (APAAP) immunostaining technique to determine their value in the differentiation between benign and malignant mesothelial cells and lung carcinoma in hi...

Polo-like kinase 1 (PLK1) has been suggested to serve as oncogene in most human cancers. The aim of our study is to present more evidence about the clinical and prognostic value of PLK1 in lung squamous cell carcinoma patients. The status of PLK1 was observed in lung adenocarcinoma, lung squamous cell carcinoma and normal lung tissues through analyzing microarray data set (GEO accession number:...

Immune complexes isolated from pleural effusions of lung carcinomas were dissociated by ion exchange chromatography in the presence of 8 M urea. The antibodies thus obtained from 2 lung adenocarcinomas and 2 squamous cell carcinomas were assayed by indirect immunofluorescence against a variety of target cells in fresh suspensions, tissue cultures, and paraffin-embedded sections. Strong cytoplas...

Detectable levels (>0.2 pinol/ID" cells) of one or more prostanoid species resultant to calcium ionophore A23187-induced biosynthesis from endogenous arachidonic acid were distributed in 28 cell lines derived from different histolÃ3gica!classes of lung tumors as follows: large cell undifferentiated carcinoma (3 of 3 cell lines); adenosquamous carcinoma (1 of 2 cell lines); squamous cell carcino...

OBJECTIVE To study the relationship between the infection of human papillomavirus (HPV) type 16, type 18, the expression of survivin, and the mutation of p53 gene in lung squamous carcinoma tissue for the research of pathogenesis of lung carcinoma. METHODS This study was carried out at the Laboratory of Molecular Biology, Xiangfan Central Hospital of Hubei Province, China from September 2008 ...

Recent studies indicate that the abnormal microenvironment of tumors may play a critical role in carcinogenesis, including lung cancer. We comprehensively assessed the number of stromal cells, especially immune/inflammatory cells, in lung cancer and evaluated their infiltration in cancers of different stages, types and metastatic characteristics potential. Immunohistochemical analysis of lung c...

Cotylenin A, a novel inducer of the differentiation of leukemia cells, and IFN-alpha synergistically inhibited the growth of and induced apoptosis in several human non-small cell lung carcinoma cell lines. Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) and its receptor DR5 were the early genes induced by the combination of cotylenin A and IFN alpha in lung carcinoma cells. Neut...

We have defined a human lung carcinoma antigen using murine monoclonal antibodies (DF-L1 and DF-L2) prepared against a primary adenocarcinoma of the lung. This antigen is expressed on the surface of human lung carcinoma cell lines and has an apparent Mr of 350,000-420,000. Immunoperoxidase staining has demonstrated expression of the antigen in the cytoplasm and membranes of adenocarcinomas and ...

The high incidence of lung cancer and ineffective toxic action of current mono and doublet chemotherapy approaches result in poor patient survival. Further, matrix metalloproteinases (MMPs) are implicated in neoplastic invasion and metastasis. Based on this, the authors investigated the effect of a dietary micronutrient mixture (NM) containing lysine, proline, arginine, ascorbic acid, and green...
