The telomeric repeat amplification protocol (TRAP) assay has been used to test telomerase activity in numerous cancer specimens. We describe primers, controls and quantification methods for the TRAP assay to accurately measure the level of telomerase activity in clinical samples. The assay is reliable and reproducible in routine analyses and can be used to(More)
Using cDNA database mining strategies and real-time quantitative reverse transcription-PCR, we identified B7-H4 as a novel gene that is overexpressed in ovarian and breast cancer tissues when compared with normal tissues. The gene encodes a protein of 282 amino acids with a signal sequence, an immunoglobulin domain, and a COOH-terminal hydrophobic(More)
PURPOSE Phosphatase of regenerating liver-3 (PRL-3) has been associated with metastasis promotion. However, clinical applications of this association have not yet been clearly demonstrated. In this study, we evaluated the relation of PRL-3 mRNA level in primary colorectal cancer to the corresponding stage and to other clinicopathologic factors. METHODS(More)
BACKGROUND Recent studies have associated telomerase with prognostic factors and survival in neuroblastoma. PROCEDURE We examined telomerase activity by telomere repeat amplification protocol (TRAP) and expression of the RNA component of telomerase (hTR) by Northern blotting in 106 primary neuroblastoma tumors and 22 established cell lines.
