Tumor cell invasion is a process regulated by integrins, matrix-degrading enzymes, and interactions with host tissue stromal cells. The ADAM family of proteins plays an important role in modulating various cellular responses. Here, we show that an alternatively spliced variant of ADAM9 is secreted by hepatic stellate cells and promotes carcinoma invasion.(More)
Human papillomavirus type 16 (HPV16) and other high-risk HPVs are etiologically linked to the development of cervical carcinomas and contribute to a number of other tumors of the anogenital tract, as well as oral cancers. The high-risk HPV E6 and E7 oncoproteins are consistently expressed in cervical cancer cells and are necessary for the induction and(More)
Small cell lung cancer (SCLC) is an aggressive type of lung cancer, and the detection of SCLCs at an early stage is necessary for successful therapy and for improving cancer survival rates. Fucosylation is one of the most common glycosylation-based modifications. Increased levels of fucosylation have been reported in a number of pathological conditions,(More)
The NF-kappaB/IkappaB signaling pathway is a critical regulator of cell survival in cancer. Here, we report that combined down-regulation of growth arrest- and DNA-damage-inducible proteins (GADD)45alpha and gamma expression by NF-kappaB is an essential step for various cancer types to escape programmed cell death. We demonstrate that inhibition of(More)
Lung cancer is recently regarded as an overhealed inflammatory disease. Serum amyloid A (SAA) is known as an acute phase protein, but it is likely involved in the cancer pathogenesis. We identified both SAA1 and SAA2 in the pooled sera of lung cancer patients but not in the healthy control, by LC-MS/MS analysis. We found that about 14-fold higher levels of(More)
Tetraspanin CD9 has been shown to regulate cell-cell fusion in sperm-egg fusion and myotube formation. However, the role of CD9 in osteoclast, another multinucleated cell type, is not still clear. Therefore, we investigated the role of CD9 in osteoclast differentiation. CD9 was expressed in osteoclast lineage cells and its expression level increased during(More)
To date, no effective treatment for patients with advanced androgen-independent prostate cancer is available, whereas androgen ablation therapy, surgery, and radiation therapy are effective in treating local, androgen-dependent tumors. The mechanisms underlying the differences between androgen-dependent and -independent prostate cancer remain elusive.(More)
Epithelium-specific ETS (ESE)-1 is a prototypic member of a novel subset of the ETS transcription factor family that is predominantly expressed in cells of epithelial origin but can also be induced in other cell types including vascular endothelial and smooth muscle cells in response to inflammatory stimuli. To further define the molecular mechanisms by(More)
Glycoproteins in human serum play fundamental roles in many biological processes, and also have clinical value as biomarkers for disease progression and treatment. In this study, we isolated glycoproteins from the sera of three healthy individuals and three lung adenocarcinoma patients using multilectin affinity chromatography. The recovered glycoproteins(More)
Neurodegenerative diseases, such as Alzheimer's disease (AD) and Parkinson's disease (PD), are characterized by progressive loss of cognitive function, dementia, and problems with movements. In order to find new protein biomarkers of high specificity from cerebrospinal fluid (CSF) of AD and PD patients, one-dimensional gel electrophoresis (1-DE) coupled(More)
