S100A6 (calcyclin) is an acidic calcium binding protein with two EF-hand motifs and overexpressed in several tumors including intrahepatic carcinoma. TNFalpha, a strong NF-kappaB activator required for hepatocyte proliferation during liver regeneration, triggered the expression of S100A6 mRNA in human hepatoblastoma cell line HepG2. Transient expression of(More)
The modulation of Bmi-1 is observed in several tumor tissues, and its heightened protein level is suspected to be involved in tumorigenesis by acting as a transcriptional repressor in the INK4a/ARF locus. To elucidate the modulation of Bmi-1 in invasive ductal breast cancers, we examined its transcript and protein levels. The bmi-1 mRNA level by reverse(More)
BACKGROUND Carcinoembryonic antigen-related cell adhesion molecule 6 (CEACAM6) inhibits anoikis and affects the malignant phenotype of cancer cells. In this study, we analyzed CEACAM6 as a gene that is highly upregulated in colon cancer tissues, and examined the assertion that CEACAM6 might be a suitable candidate tumor marker for the diagnosis of colon(More)
To clarify the roles of Bmi-1 in colorectal carcinoma, we examined the expression of Bmi-1 in 41 samples out of 46 colorectal carcinomas by reverse transcription-PCR, whereas all 46 were analyzed by immunostaining. In addition, we analyzed the expression patterns of Bmi-1 in association with p16INK4a and p14ARF (in mouse p19ARF) in a series of colorectal(More)
Presellar extension of the bone window combined with removal of the sellar floor results in the transsphenoidal supradiaphragmatic intradural approach. One tuberculum sella meningioma and another suprasellar Rathke's cleft cyst confined to the pituitary stalk were removed via this approach. The presellar extension of the bone window was performed with the(More)
Dendritic cells (DCs) are most potent among the antigen-presenting cells and are believed to be crucial for the initiation of a primary T-cell response to foreign antigens. Mycobacterial infection within macrophages is controlled by cell-mediated immunity. To elucidate the stimulation of immune response by Mycobacterium bovis bacillus Calmette-Guérin (BCG),(More)
Cervical cancer is known to be highly associated with viral oncogene E6 and E7 of human papilloma virus. Down-regulation of oncogene expression by antisense-based gene therapy has been extensively studied. To investigate the effect of HPV 16 E6 antisense nucleic acid (AS) on cervical cancer cells, human cervical cancer cell lines, CaSki and SiHa cells(More)
Recently, a potent transforming gene which was exclusively expressed in rat pituitary tumor but not in normal pituitary had been isolated and named as pituitary tumor transforming gene (PTTG). A cDNA clone encoding human homologue of rat PTTG was isolated from human fetal liver cDNA library. It contained an open reading frame of 603 base pairs predicting a(More)
The cDNA clones, which were highly expressed in liver tissues of hepatocellular carcinoma (HCC) patients, were identified using dot hybridization and reconfirmed by Northern blot analysis. One of the clones, ninjurin (nerve injury induced protein), showed a much higher expression level in the liver tissue of HCC patients than in normal liver tissue.(More)
Monoclonal antibodies against progesterone conjugated to carrier protein through substituent on the A-ring (C3 position ) or the C-ring (C11 position) of progesterone were used in the enzyme immunoassay. Antibody specificities were determined by testing the ability of 11 represensitive steroids to displace labelled progesterone in a competitive enzyme(More)
