SUMMARY We previously reported acid-extracted natural antigenic peptide (F4.2 [YSWMDISCWI]) of a gastric signet ring cell carcinoma HST-2 cells, recognized by HLA-A*31012-restricted autologous cytotoxic T lymphocytes, TcHST-2 line. In this study, the full-length cDNA (1101 bp), termed c98, predicting a protein composed of 170 amino acids was obtained.(More)
Telomerase activation is a characteristic of immortalized tumor cells but not of normal cells. Telomerase activity has been detected in approximately 85% of malignant tumors, and assaying for telomerase activity is thought to be useful for diagnosing cancer. Three telomerase-associated molecules [human telomerase RNA component (hTR), telomerase-associated(More)
Telomerase adds hexameric repeats of 5′-TTAGGG-3′ to the ends of chromosomal DNA (telomere) and has been implicated in cell immortalization and cellular senescence. The aim of this study was to measure quantitatively the telomerase activity and human telomerase RNA component (hTR) content in gastric cancer and to examine the relation between these values(More)
Rectal prolapses are not life-threatening, however the bleeding and fecal incontinence associated with them significantly erode quality of life and can cause concern among patients' caregivers in nursing homes. Many procedures have been reported that repair rectal prolapses, and the procedure used depends on the severity of the prolapse; however, the(More)
