Sequence alterations of mitotic checkpoint genes, hBUB1 and hBUBR1, were examined, and their gene transcripts were quantified using on-line, real-time quantitative reverse transcription-PCR in surgically resected human colorectal cancers and their neighboring normal tissues. Our results reveal a new hBUB1 missense mutation (Ala130Ser) but not any hBUBR1(More)
To date, 10 members of the UDP-N-acetyl-alpha-d-galactosamine:polypeptide N-acetylgalactosaminyltransferase (pp-GalNAc-T) family have been cloned and analyzed in human. In this study, we cloned and analyzed a novel human pp-GalNAc-T from an NT2 cell cDNA library, and we named it pp-GalNAc-T13. In amino acid sequences, pp-GalNAc-T13 was highly homologous,(More)
OBJECTIVE Adipocytes secrete a number of molecules such as tumor necrosis factor-alpha, leptin and free fatty acids that can influence the ability of the body to metabolize glucose. Recently, a novel 12.5 kDa cysteine-rich protein, termed resistin, was shown to be secreted by adipocytes. Resistin expression was markedly induced during the conversion of(More)
We identified a novel alternatively spliced isoform of PR mRNA in breast cancer tissues. The deleted transcript was characterized by an out-of-frame deletion of 437 bp, corresponding to the complete loss of exons 4 and 6 (PR delta4+6 ASV). PR delta4+6 ASV will result in a partial defect in the region of the ligand-binding domain of hormone receptors,(More)
RT-nested PCR has been introduced as a highly specific and sensitive assay method to detect the prostate-specific membrane antigen (PSM) mRNA in peripheral blood. However, appreciable percentages of false-positive cases have been reported. Additionally, primer sets reported previously could not discriminate between PSM and PSM', an alternatively spliced(More)
Telomerase activity and hTERT mRNA expression are upregulated in colorectal cancer. Whether they are inherent in colorectal adenomas, premalignant lesions to cancer, however, remains to be elucidated. We examined telomerase activity by the fluorescence-based telomeric repeat amplification protocol method and analyzed the level of hTERT mRNA by real-time(More)
The aim of the present study was to examine the production efficiency of cloned pigs by serial somatic cell nuclear transfer (SCNT) and to ascertain any changes in the telomere lengths of multiple generations of pigs. Using fetal fibroblasts as the starting nuclear donor cells, porcine salivary gland progenitor cells were collected from the resultant(More)
This study investigated the relationship of telomerase activity to its clinical implications in hepatocellular carcinoma (HCC). Telomerase activity was quantatively examined by a non-radioisotope quantitative system based on a TRAP-eze (ONCOR) in 42 HCC nodules and 40 non-cancerous liver tissue adjacent to the HCC nodules, obtained by surgical resection.(More)
Survivin functions to suppress cell death and regulate cell division, and is observed uniquely in tumor cells and developmental cells. However, the expression and regulation of survivin in non-transformed cells are not well elucidated. Therefore, we investigated the expression of survivin in a murine liver regeneration model after partial hepatectomy and(More)
The human progesterone receptor (PR) is a ligand-activated nuclear transcription factor that mediates progesterone action in target tissues. We found a novel alternatively spliced variant (ASV) of the PR mRNA in breast cancer tissues. The deleted transcript was characterized by an out-of-frame deletion of 52 bp in exon 6 (PR delta6/2 ASV). The PR delta6/2(More)
