Previously we reported that the hypoxia-inducible factor-1alpha (HIF-1alpha) expression correlated with cell proliferation and apoptosis under 500 mM of CoCl2 treatment in a human gastric carcinoma cell line, MKN-1. Herein we report a similar correlation in other cell lines, MKN-45 and TMK-1. The dual-phase expression of HIF-1alpha was highest at 6 and 8 h(More)
OBJECTIVE CYR61 (cysteine-rich 61) belongs to the CCN (CYR61/CTGF/NOV) protein family and is involved in tumorigenesis. We have previously confirmed that the level of CYR61 protein is decreased in gastric carcinoma compared with nontumoral mucosa, by conducting proteome-based analyses. In this study, we examine the relationship between CYR61 expression and(More)
A variety of human cancer cells are resistant to Fas ligand and anti-Fas antibody induced apoptosis. Previously, we reported that human gastric carcinoma cell lines were resistant to the anti-Fas antibody, CH-11, without interferon-gamma pretreatment in vitro. Cyclooxygenase (COX)-2 is known to be expressed in many human malignancies, and is correlated with(More)
We have recently isolated a gene, Ankyrin-repeated protein with a proline-rich region (ARPP), that is highly expressed in the skeletal and cardiac muscle. Our previous immunohistochemical analysis revealed that ARPP expression was augmented in rhabdomyosarcoma but scarcely detectable in leiomyosarcoma, showing that ARPP is a useful marker for(More)
