Chromosome 11Q23

The yeast artificial chromosome (YAC-13HH4), which spans a 440-kb region of DNA just distal to the CD3 locus on chromosome 11 at band q23, has been used to characterize a range of chromosomal translocations in acute leukemias from both adults and infants. In situ hybridization was performed on metaphase cells from bone marrow of 17 leukemias and two cell lines with a variety of chromosome 11q23 abnormalities. It was established that in infant leukemias the translocations t(11;19), t(4;11), and t(5;11) had occurred in the region defined by YAC 13HH4. Additionally, the translocations t(4;11), t(6;11), t(9;11), t(X;11), and t(10;11) in other leukemias were found to disrupt the same region of chromosome 11q23, although an exception was found in one t(6;11) translocation for which the breakpoint was distal to the YAC. One patient had a t(9;11) translocation in a therapy- related leukemia, suggesting that this class of etoposide-related malignancy has similar breakpoints to those occurring in de novo leukemias. An example of a lymphoma-derived translocation t(4;11) was shown to involve a deletion of the region defined by YAC 13HH4. A leukemia with a deletion on chromosome 11 (q23-q25) was also studied and it was shown that the YAC sequence was unaffected. It was concluded that, with a few exceptions, the translocations at 11q23 in a wide range of acute infant and adult leukemias occur in a common region and may result from a common underlying mechanism.

Human Genes

Arylamine N-acetyltransferase is encoded at two loci, AAC-1 and AAC-2, on human chromosome 8. The products of the two loci are able to catalyse N-acetylation of arylamine carcinogens, such as benzidine and other xenobiotics. AAC-2 is polymorphic and individuals carrying the slow-acetylator phenotype are more susceptible to benzidine-induced bladder cancer. We have identified yeast artificial chromosome clones encoding AAC-1 and AAC-2 and have used the cloned DNAs as fluorescent probes for in situ hybridization. The hybridization patterns allow assignment of AAC-1 and AAC-2 to chromosome 8p21.3-23.1, a region in which deletions have been associated with bladder cancer [Knowles, Shaw and Proctor (1993) Oncogene 8, 1357-1364].

Myc Gene

Translocations involving chromosome 8 at band q24 and one of the Ig loci on chromosomes 14q32, 22q11, and 2p11 are the hallmark of Burkitt's lymphoma (BL). It has been previously observed that the exact localization of the breakpoints at chromosome 8q24 can vary significantly from patient to patient, scattering over a distance of more than 300 kb upstream of c-myc and about 300 kb downstream of c-myc. To generate probes for fluorescence in situ hybridization (FISH) that detect most c-myc translocations, we screened a yeast artificial chromosome (YAC) library from normal human lymphocytes by colony hybridization, using three markers surrounding the c-myc gene as probes. We obtained 10 YAC clones ranging in size between 500 and 200 kb. Two nonchimeric clones were used for FISH on several BL cell lines and patient samples with different breakpoints at 8q24. Our results show that the YAC clones detected translocations scattered along approximately 200 kb in both metaphase chromosomes and interphase nuclei. The sensitivity, rapidity, and feasibility in nondividing cells render FISH an important diagnostic tool. Furthermore, the use of large DNA fragments such as YACs greatly simplifies the detection of translocations with widely scattered breakpoints such as these seen in BL.

Fluorescence in situ hybridization (FISH) on human chromosomes in meta-and interphase is a well-established technique in clinical and tumor cytogenetics and for studies of evolution and interphase architecture. Many different protocols for labeling the DNA probes used for FISH have been published. Here we describe for the first time the successful use of Photoprobe biotin-labeled DNA probes in FISH experiments. Yeast artificial chromosome (YAC) and whole chromosome painting (wcp) probes were tested.

14Q32 Translocation

Abstract Partner sites of 14q32 translocations found in B-cell malignancies were detected by fluorescence in situ hybridization (FISH) using yeast artificial chromosome (YAC) clones, Y20 and Y6, containing the human Ig heavy chain (IgH) gene locus. Y20 spans a 160-kb upstream and 40-kb downstream region of the JH segments on chromosome band 14q32.33. Y6 is 300-kb upstream of Y20, and spans a further 320-kb telomeric region. The human DNA sequences amplified by Alu polymerase chain reaction of the YAC clones were used as probes for FISH to study six patients with non-Hodgkin's lymphoma (NHL), one patient with acute lymphoblastic leukemia, and one cell line FR4 established from a plasmacytoma. Three telomeric YAC clones each specific for 3q, 8q, and 18q were also used to further characterize 14q32 translocations. The IgH YACs were successfully applied to detect cytogenetically invisible subtelomeric translocation of the IgH gene locus to each partner site in t(14;18), t(8;14), and t(14;19), and to identify t(3;14) (q27;q32.33) in three patients with 14q32 translocation of unknown origin. Furthermore, complex translocations involving more than three chromosomes were detected in an NHL patient with t(8;14), and t(3;12), and in the FR4 with der(14)t(8;14), der(8)dic(1;8), and del(1)(q21). The technique would be a useful tool in elucidating the mechanisms of a 14q32 translocation in B-cell malignancies.

Hybridization Mapping

Translocations and deletions of the short arm of chromosome 12 [t(12p) and del(12p)] are common recurring abnormalities in a broad spectrum of hematologic malignant diseases. We studied 20 patients and one cell line whose cells contained 12p13 translocations and/or 12p deletions using fluorescence in situ hybridization (FISH) with phage, plasmid, and cosmid probes that we previously mapped and ordered on 12p12–13. FISH analysis showed that the 12p13 translocation breakpoints were clustered between two cosmids, D12S133 and D12S142, in 11 of 12 patients and in one cell line. FISH analysis of 11 patients with deletions demonstrated that the deletions were interstitial rather than terminal and that the distal part of 12p12, including the GDI-D4 gene and D12S54 marker, was deleted in all 11 patients. Moreover, FISH analysis showed that cells from 3 of these patients contained both a del(12p) and a 12p13 translocation and that the affected regions of these rearrangements appeared to overlap. We identified three yeast artificial chromosome (YAC) clones that span all the 12p13 translocation breakpoints mapped between D12S133 and D12S142. They have inserts of human DNA between 1.39 and 1.67 Mb. Because the region between D12S133 and D12S142 also represents the telomeric border of the smallest commonly deleted region of 12p, we also studied patients with a del(12p) using these YACs. The smallest YAC, 964c10, was deleted in 8 of 9 patients studied. In the other patient, the YAC labeled the del(12p) chromosome more weakly than the normal chromosome 12, suggesting that a part of the YAC was deleted. Thus, most 12p13 translocation breakpoints were clustered within the sequences contained in the 1.39 Mb YAC and this YAC appears to include the telomeric border of the smallest commonly deleted region. Whether the same gene is involved in both the translocations and deletions is presently unknown.
