We report the case of a patient having Philadelphia-negative, bcr-abl-positive chronic myeloid leukemia. In situ hybridization showed the presence of the bcr-abl fusion on the chromosome 9 long arm in all mitoses observed. Stability of the disease was very difficult to obtain because of serious adverse effects to interferon and chemotherapy, mainly grade IV… (More)
Repair rates of mismatched nucleotides located at an activating hotspot of mutation, H-ras codon 12, have been analyzed in vivo in mammalian cells. Repair rates at codon 12 are significantly improved in cells synchronized to the G(1) stage of the mammalian cell cycle as compared with non-synchronous cells, demonstrating that mismatch repair mechanisms are… (More)
Defective mismatch repair has recently been implicated as the major contributor towards the mutator phenotype observed in tumour cell lines derived from patients diagnosed with hereditary non-polyposis colon cancer (HNPCC). Cell lines from other cancer-prone syndromes, such as xeroderma pigmentosum, have been found to be defective in nucleotide excision… (More)
CD28 is a cell surface molecule present on most peripheral T cells which has been implied in the amplification of the T-cell response in vitro. Using in situ hybridization on human prometaphase cells, we have found that the human CD28 gene maps to chromosome 2 at bands q33–q34, as shown previously for the CTLA-4 gene. CD28 and CTLA-4 are both members of the… (More)
The HST/FGFK gene, a member of the fibroblast growth factor gene family and a protooncogene, is localized on chromosomal band 11q13. Genes in this region are frequently involved in hematopoietic and solid tumors. Here we show that the HST gene lies telomeric to the BCL1 gene, the t(11;14)(q13;q32) breakpoint, and the FRA11A rare fragile site.
IFI-56K and IFI-54K are two human genes that are strongly induced by interferon and viruses. These genes are closely related at the protein, RNA, and promoter levels. By means of the somatic cell hybrid technique, the two genes have been previously located on chromosome 10. Using in situ hybridization, we show here that both IFI-54K and IFI-56K genes map to… (More)
Computational methods are described which increase the efficiency of the RNA folding algorithm described by Zuker and Stiegler. Bit addressing has been used to reduce the memory requirements from 2NxN to NxN/2. The order in which the nucleotide sequence is examined internally has been altered, and some additional short arrays which carry temporary… (More)
Using in situ chromosomal hybridization, we have mapped the gene encoding the basic fibroblast growth factor to chromosome 4 at bands q26-q27. This location is on the same chromosome as that of a related gene, FGF.5, but on a distinct region.
The FLG/FGFRI gene, encoding a receptor for members of the FGF family, is located at 8p11.2-p12. It is amplified, overexpressed, and not grossly rearranged in the MDA-MB-134 breast carcinoma cell line, whereas other genes from the pericentromeric 8p region are not amplified. The FGF4/HSTFI gene, located at 11q13, is also amplified with a substantial portion… (More)
