It is frequent for news items to lead to a short lived temporary increase in interest in a particular health related service, however it is rare for this to have a long lasting effect. In 2013, in the UK in particular, there has been unprecedented publicity in hereditary breast cancer, with Angelina Jolie’s decision to have genetic testing for the BRCA1(More)
Background Genetic predisposition to inflammatory bowel disease (IBD) has been shown by epidemiological and linkage studies. Genetic linkage of IBD to chromosome 16 has been previously observed and replicated in independent populations. The recently identified NOD2 gene is a good positional and functional candidate gene since it is located in the region of(More)
Telomerase is crucial for human carcinogenesis. The limiting component of telomerase activity is telomerase reverse transcriptase (hTERT), undetectable in differentiated somatic cells but present in most tumor cells. There is evidence that hTERT transcription is shut down by a repressor in normal cells, but the mechanisms that turn on or maintain expression(More)
Telomerase is required for the complete replication of chromosomal ends. In tumors, the human telomerase reverse transcriptase subunit (hTERT) is up-regulated, thereby removing a critical barrier for unlimited cell proliferation. To understand more about hTERT regulation, we measured hTERT RNA levels by quantitative reverse transcription (RT)-PCR.(More)
Telomere lengths in radiosensitive murine lymphoma cells L5178Y-S and parental radioresistant L5178Y cells were measured by quantitative fluorescence in situ hybridization. Results revealed a 7-fold reduction in telomere length in radiosensitive cells (7 kb) in comparison with radioresistant cells (48 kb). Therefore, it was reasoned that telomere length(More)
Losses of heterozygosity involving chromosomes 9 and 10 are frequent events in the development and progression of cutaneous malignant melanoma. To investigate whether specifically deleted chromosomal regions encode tumor suppressor genes (TSGs), we introduced normal chromosome 10 into the tumorigenic human metastatic melanoma cell line UACC-903 by microcell(More)
Twenty-three patients with advanced NSCLC were treated with high dose chemotherapy using four agents and autologous bone marrow reinfusion. Ten patients received two bolus doses of cyclophosphamide (maximum tolerated total dose 10 G m-2), ifosfamide as a 24 h infusion (11 G m-2) followed by mitomycin C (70 mg m-2) as a subsequent 24 h infusion and mustine(More)
We read with interest the article by de Jong and colleagues (Gut 2003;52:547–51) reporting studies of genetic associations between DNA polymorphisms in xenobiotic metabo-lising genes and Crohn's disease (CD). The authors employed a case control study design to test seven polymorphisms in five candidate genes for disease association. Evidence was found for a(More)
Contrast-coding was investigated in amblyopic, fellow non-amblyopic and control eyes. Using a contrast-matching paradigm similar to Georgeson and Sullivan [J. Physiol. 252, 627-656 (1975)], amblyopic eyes were found to have a high frequency contrast-coding deficit not only at threshold but also at suprathreshold levels up to at least 0.45 contrast. The(More)
Interleukin 6 (IL-6) serves as a growth factor for mouse plasmacytomas. As a model for IL-6-mediated growth of plasmacytomas, we study IL-6-dependent B-cell hybridomas, which can be generated through fusion of B lymphocytes with a plasmacytoma cell line, e.g., SP2/0. In the present report, we have investigated the peculiar behavior of B-cell hybridomas with(More)
