HT-29 cells resistant to 10(-6) M methotrexate (HT29-MTX) secrete mucins with gastric immunoreactivity (Lesuffleur, T., Barbat, A., Dussaulx, E., and Zweibaum, A. (1990) Cancer Res. 50, 6334-6343). A 3310-base pair mucin cDNA clone (L31) was isolated from an HT29-MTX expression library using a polyclonal serum specific for normal gastric mucosa. It shows a(More)
Four distinct genes that encode mucins have previously been mapped to chromosome 11p15.5. Three of these genes (MUC2, MUC5AC, and MUC6) show a high level of genetically determined polymorphism and were analyzed in the CEPH families. Linkage analysis placed all three genes on the genetic map in a cluster between HRAS and INS, and more detailed analysis of(More)
A family of four genes that encode major secreted mucins (MUC6, MUC2, MUC5AC and MUC5B) map to within 400kb on chromosome 11p15.5. These genes contain long stretches of tandem repeats of sequence that encode serine- and threonine-rich domains but that otherwise show no similarity from gene to gene, and regions of unique sequence domains that do show(More)
A family of four highly polymorphic genes encoding secreted gel forming mucins is located in the middle of a recombination rich region of the short arm of chromosome 11 (11p15.5; tel MUC6-MUC2-MUC5AC-MUC5B cen; approx. 400 kb). These genes are of interest as risk factors for inflammatory diseases of the epithelia, and we have for example reported(More)
The t(11;22) is the most common recurrent non-Robertsonian constitutional translocation in humans, having been reported in more than 160 unrelated families. Balanced carriers are at risk of having offspring with the derivative 22 syndrome owing to 3:1 meiotic non-disjunction event. Clinical features of the der(22) syndrome include mental retardation,(More)
Antibody engineering provides the potential to clone and manipulate antibody genes to produce fragments with altered specificity. We have produced an anti- Legionella single chain fragment with broader specificity towards Legionella serotypes than the parent monoclonal antibody. Using this relationship between the parent monoclonal and the recombinant(More)
MUC3 is a large mucin glycoprotein expressed by the human intestine and gall bladder. In this manuscript, we present details of the deduced protein structure of MUC3. The MUC3 carboxyl-terminal domain is 617 residues in length, including 511 residues of a non-repetitive mucin-like domain (27% Thr, 22% Ser, and 11% Pro) and a 106-residue Cys-rich domain with(More)
We report the molecular characterization of a reciprocal constitutional translocation t(7;22)(p13;q11.2) carried by three family members who have each developed a hematological malignancy. The chromosome 7 breakpoint was localized to a single BAC clone, RP11-571N3, by sequential fluorescence in situ hybridization analysis of clones selected from the NCBI(More)
The t(10;11)(p13;q14-21) is a non-random translocation described in acute lymphoblastic and myeloid leukaemias. It results in the fusion of the gene CALM, which encodes a clathrin assembly protein, on 11q14 to the gene AF10, a putative transcription factor on 10p13. Here we describe for the first time, the occurrence of a CALM-AF10 fusion in a case of acute(More)
A region of 150 kb has been analysed around a previously isolated, lymphoma associated, translocation breakpoint located at chromosome band 11q23. This balanced and reciprocal translocation, t(11;14)(q32;q23), has been shown to result in the fusion between chromosome 11 specific sequence and the switch gamma4 region of the IGH locus. The LPC gene, encoding(More)
