Abstract
Since the beginning of the 20th century, scientists have tried to stimulate the anti-tumour activities of the immune system to fight against cancer. However, the scientific effort devoted on the development of cancer immunotherapy has not been translated into the expected clinical success. On the contrary, classical anti-neoplastic treatments such as surgery, radiotherapy and chemotherapy are the first line of treatment. Nevertheless, there is compelling evidence on the immunogenicity of cancer cells, and the capacity of the immune system to expand cancer-specific effector cytotoxic T cells. However, the effective activation of anti-cancer T cell responses strongly depends on efficient tumour antigen presentation from professional antigen presenting cells such as dendritic cells (DCs). Several strategies have been used to boost DC antigen presenting functions, but at the end cancer immunotherapy is not as effective as would be expected according to preclinical models. In this review we comment on these discrepancies, focusing our attention on the contribution of regulatory T cells and myeloid-derived suppressor cells to the lack of therapeutic success of DC-based cancer immunotherapy.

Abstract
Mammalian Enabled (Mena) is a mammalian homologue of Drosophila Enabled (Ena), which genetically interacts with Drosophila Abl tyrosine kinase. The signaling pathway involving c-Abl and Mena (Ena) is not fully understood. To find molecules that participate in the c-Abl/Mena pathway, we searched for Mena-binding proteins using a yeast two-hybrid system. We identified Abl interactor 1 (Abi-1), which is known to interact with c-Abl, as a binding protein for Mena. Binding analysis revealed that the Ena/Vasp homology 1 domain of Mena and the polyproline structure of Abi-1 are necessary for the interaction. The interaction between Mena and Abi-1 was also observed in a mammalian expression system. Importantly, Abi-1 dramatically promoted c-Abl-mediated tyrosine phosphorylation of Mena but not other substrates such as c-Cbl. Mutational analysis demonstrated that the phosphorylation site of Mena is Tyr-296. Our results suggest that Abi-1 regulates c-Abl-mediated phosphorylation of Mena by interacting with both proteins.

Abstract
The authors report a unique translocation in a patient with M7 acute myeloid leukemia and review the literature. A 22-month-old girl without Down syndrome was diagnosed with acute myeloid leukemia, subtype M7 (AML-M7), and died with relapsed disease following bone marrow transplantation. Tumor cells were evaluated using cytogenetics (including spectral karyotyping), immunohistochemistry, and flow cytometry. The patient was found to have a previously unreported complex translocation as follows: 50,XX,der(1)t(1;5)(p36?.1;p15?.1),del(5)(p15?.1), +6,+der(6;7)(?;?),der(7)t(6;7)(?;p22)[2],der(9)t(6;9) (?;p21)t(9;14)(q34;q11.2-q13),+10,t(12;16)(p13;q24),-14[2], del(14)(q13)[2],+der(19)t(1;19)(?;p13.3),+22[cp 4]. AML-M7 in non-Down syndrome patients is a rare disease that requires improved prognostic markers.

Abstract
The development of dense genetic maps of mammalian chromosomes is facilitated when chromosome-specific libraries are used as a source of genetic markers. To saturate the genetic maps of mouse chromosomes 4 and 6, we have made use of fluorescent-activated chromosome sorting to purify a 4:6 Robertsonian chromosome from a cell line harboring the Rb(4:6)2Bnr translocation. After staining with chromomycin A3 and Hoechst 33528, this chromosome was separated from the other mouse chromosomes. DNA was isolated from the fraction containing the Robertsonian chromosome and subcloned into the insertion vector lambda gt10, generating a library with 4.6 x 10(5) independent phage. A total of 19 single-copy sequences were used to type the progeny of a C57BL/6J x Mus spretus backcross that had previously been typed for loci on chromosomes 4 and 6. Approximately 70% of the clones in the library mapped to either chromosome 4 or 6 as assessed by genetic mapping and by use of a somatic cell hybrid panel. Simple sequence repeats have also been isolated from this library. Further characterization of these microsatellites should accelerate efforts to map mouse chromosomes 4 and 6 using PCR. In addition, flow sorting of Robertsonian chromosomes suggests a general approach for making chromosome-specific libraries in mouse.

Abstract
We have introduced a substitution mutation into the c-abl locus of murine embryonic stem cells by homologous recombination between exogenously added DNA and the endogenous gene. Model constructs were initially generated that consisted of a promoterless selectable neomycin resistance marker inserted into the v-abl gene of the complete Abelson murine leukemia virus genome, designed to be expressed either as a fusion protein or by translational restart. Tests of these viral genomes for transmission of v-abl and neo markers showed more stable coexpression in a protein fusion construct. The neo fusion was subcloned from this v-abl construct into a promoterless c-abl fragment, and the resulting DNA was used to transform embryonic stem cells. Direct screening of genomic DNAs showed that a high proportion of drug-resistant clones arose from homologous recombination into the endogenous c-abl locus.

Abstract
Interspecific backcross mice were used to create a molecular genetic linkage map of chromosome 2. Genomic DNAs from N2 progeny were subjected to Southern blot analysis using molecular probes that identified the Abl, Acra, Ass, C5, Cas-1, Fshb, Gcg, Hox-5.1, Jgf-1, Kras-3, Ltk, Pax-1, Prn-p, and Spna-2 loci; these loci were added to the 11 loci previously mapped to the distal region of chromosome 2 in the same interspecific backcross to generate a composite multilocus linkage map. Several loci mapped near, and may be the same as, known mutations. Comparisons between the mouse and the human genomes indicate that mouse chromosome 2 contains regions homologous to at least six human chromosomes. Mouse models for human diseases are discussed.

Abstract
Two proto-oncogenes, Abl and Mos, have been physically localized on their respective mouse chromosomes by in situ hybridization. By means of Robertsonian translocations to facilitate chromosome identification, Abl was regionally assigned to 2B while Mos was assigned to 4A1-A2. Polymorphisms for these genes have not been reported in genomic DNA from standard inbred strains, nor were they found in this study, thereby prohibiting genetic mapping by meiotic recombination. These physical mapping data, however, extend the number of homologous genes assigned to chromosomal regions in both man and mouse, and better define the segments of conservation on mouse chromosome 2/human chromosome 9 and mouse chromosome 4/human chromosome 8, respectively.

Abstract
A library of Abelson murine leukemia virus (A-MuLV) proviral DNAs with 12- or 6-base-pair (bp) insertional mutations was constructed. The 29 mutations characterized spanned the entire protein-coding region of the provirus. We tested the effects of these mutations both on the kinase activity of the gag-abl fusion protein encoded by the provirus and on the ability of the provirus to transform NIH 3T3 fibroblasts. To simplify assessment of the mutant kinases, we expressed the A-MuLV-encoded kinase in the bacterial expression vector pATH2, resulting in production of a trpE-gag-abl fusion protein in Escherichia coli. We used an immunoprecipitation kinase assay to measure both autophosphorylation and artificial substrate phosphorylation by the mutant kinases. To assay transformation ability of the mutant proviruses, we transfected NIH 3T3 fibroblasts with the mutants and with helper virus (Moloney MuLV) by the DEAE-dextran method. Our analysis of these A-MuLV insertional mutants allows the division of the protein-coding region of the provirus into four domains: domain A (proviral bp 1068 to 1685), in which insertions have no effect on the bacterially expressed kinase, but diminish both kinase activity and transformation efficiency in fibroblasts; domain B (bp 1750 to 2078), in which insertions have no effect on the provirus; domain C (bp 2181 to 2878), the critical kinase domain, in which 12-bp or even 6-bp insertions completely inactivate the A-MuLV kinase and result in transformation-defective proviruses; and domain D (bp 2956 to 4610), the large C-terminal domain in which mutations are silent.

Abstract
A great deal of information has emerged over the past decade regarding the gene structures and corresponding protein products of the cellular and transformation-associated forms of the ABL tyrosine kinase family. Many reports have also detailed the biological effects of these proteins (particularly the viral ABL forms) on a broad range of cell types. However, in spite of all these research efforts, the precise role of the ABL gene in normal and neoplastic growth remains to be determined. To elucidate the mechanism of action of normal and altered ABL proteins, it is imperative to identify their relevant cellular substrates and establish the role of the ABL target proteins in transformation and normal cellular growth. The availability of temperature-sensitive ABL proteins, coupled with the use of sensitive anti-phosphotyrosine antibodies, should be useful in this respect. Purification of enzymatically active, intact forms of the ABL proteins produced in insect cells by employing baculovirus expression vectors should permit direct comparison of the biochemical properties and tertiary structures of the various members of the ABL protein kinase family. Such studies will aid in understanding the nature of the alteration of ABL which results in the activation of its transforming potential. Furthermore, the availability of purified ABL proteins should permit examination of interactions of ABL with other growth-regulatory proteins, such as growth factor receptors. It has been shown that transformation-associated ABL proteins interact with the IL-3, IL-2 and GM-CSF growth-factor pathways. These and other components of the cellular signalling pathways are potential ABL targets. The elucidation of ABL function by a variety of approaches such as those described above will ultimately aid in the development of far-reaching therapeutic treatments for at least two forms of human leukaemia: Ph positive CML and Ph positive ALL.

Abstract
Dsi-1 is a region of chromosomal DNA that underwent proviral insertion in 3 of 24 Moloney murine leukemia virus-induced rat thymomas. In one of these tumors, a provirus is also integrated adjacent to the proto-oncogene c-myc. The proviruses in Dsi-1 have been characterized and appear to be complete. The proviruses were located within a 2-kilobase region that contained four prominent DNase I-hypersensitive sites. These hypersensitive sites were observed in Moloney murine leukemia virus-induced thymomas but not in NRK cells. The region of Dsi-1 immediately 3' to the insertions cross-hybridized with human and chicken DNA, indicating that it contains highly conserved sequences. No evidence could be found for the expression of this highly conserved region. Dsi-1 was mapped to mouse chromosome 4. This location demonstrates that Dsi-1 is different from 16 of the known proto-oncogenes (c-abl, c-erbA c-erbB, c-ets-1, c-ets-2, c-fes, c-fos, c-myb, c-myc, c-raf, A-raf, c-Ha-ras, c-Ki-ras, N-ras, c-sis, and c-src) and 12 cellular regions of tumor-associated integrations in retrovirus-induced tumors (c-erbB, Fis-1, int-1, int-2, Mis-1/pvt-1, Mlvi-1, Mlvi-2, c-mos, c-myb, c-myc, Pim-1, and c-Ha-ras). Hybridization experiments indicated that Dsi-1 is probably different from five additional proto-oncogenes (c-fgr, c-fms, c-mos, neu, and c-yes) and from two additional frequent integration regions (lck and Mlvi-3).

Abstract
Recent developments in molecular biology related to the Ph chromosome lead us to an evaluation of knowledge regarding this chromosome. The molecular advances are related to two cellular oncogenes, c-abl and c-sis, and also to the identification and molecular cloning of specific areas of DNA (e.g., band 22q11), permitting the isolation of a probe specific for the translocation breakpoint domain. In the preponderant number of cases examined, it was found that the breakpoints at 22q11 occur within a limited region of up to 5-6 kb, for which the term "breakpoint cluster region" (bcr) has been suggested. In contrast, breaks at 9q34 seem to occur within a much larger region at the molecular level. Yet to be established is the exact genetic composition of the bcr and a determination as to whether or not the breaks leading to the disease occur preferentially within specific areas. In spite of this level of knowledge, we do not understand how the Ph chromosome participates in CML. If Ph-positive CML is ultimately associated with a cascade of gene activations, the unraveling of their nature and chronology will undoubtedly tell us much of their contribution to the biology of CML, in particular, and to neoplasia, in general. In this respect, the rather clear description of CML in cytogenetic, clinical, and laboratory terms, the relatively long chronic phase of the disease, and the association of the blastic phase with nonrandom chromosome changes (at least in the initial phases of the disease) make Ph-positive CML an excellent candidate for a model for the study of molecular events in human neoplasia.

Abstract
Localization of cellular oncogenes (c-onc) near the break points of translocations in tumor cells has indicated involvement of these genes in neoplastic growth. Enhanced transcription of the cellular homolog (c-abl) of the transforming sequence of Abelson murine leukemia virus was observed in K3D, which was one of the cloned cell lines of 7,12-dimethylbenz[a]anthracene-induced rat erythroblastic leukemia. Since the c-abl activation was not observed in the parent cell line (K2D) from which K3D was derived and the latter was different from the former in the presence of a new marker chromosome, t(3;12), this marker may play a role in the expression of c-abl in K3D cells. In contrast to the human c-onc assignments, few rat c-onc assignments have been reported. In situ molecular hybridization studies assigned c-abl to the 3q12 site of the normal chromosome 3 and to the break point of the translocation t(3;12) in K3D cells. Another break point in this translocation chromosome 12p11 involves the nucleolar region, and the 3;12 translocation may involve c-abl and nucleolar cistrons. These results provide evidence of secondary c-onc activation during karyotypic evolution of cloned malignant cells.

Abstract
We have created an insertional mutation that leads to a severe defect in the pattern of limb formation in the developing mouse. The novel recessive mutation is phenotypically identical and non-complementary to two previously encountered limb deformity mutations, and is closely linked to a dominant mutation that gives rise to a related limb dysmorphism. The inserted element thus provides a molecular genetic link with the control of pattern formation in the mammalian embryo.

Abstract
Experiments have been carried out to establish the relative position of the mouse Ig heavy chain locus and the c-myc oncogene. In mouse plasmacytoma with the typical rcpt(12;15) chromosome translocation the c-myc oncogene is juxtaposed to one of the heavy chain genes in a head-to-head orientation. Since the relative orientations of the c-myc locus and the Ig heavy chain gene cluster on the corresponding mouse chromosomes had not been settled, it was not known whether the rearranged c-myc gene is transposed to chromosome 12 or remains on chromosome 15. To decide which of the two alternatives is correct, we separated the translocation chromosomes by fluorescence-activated chromosome sorting. The separated chromosomal fractions were hybridized with myc-specific DNA probes corresponding to the first or second/third exons in a chromosome spot assay. The results presented here indicate that the c-myc gene in mouse plasmacytoma carrying the typical translocation, as in the human Burkitt lymphoma analogous translocation, transposes to the chromosome carrying the Ig heavy chain locus. These results also establish the orientations of the Ig heavy chain locus and the c-myc locus on their normal chromosomes.

Abstract
A new technique was developed for in situ hybridization on isolated murine chromosomes. The safety and relative rapidity of the method is due to the ready availability of large numbers of isolated "target" chromosomes with well preserved morphology. Its applicability was demonstrated by mapping c-myc to band 15D of Robertsonian (6;15) fusion chromosomes. This localization coincides with the cytogenetic mapping of the translocation breakpoints in mouse plasmacytomas that carry the typical rcpt (12;15) translocation.

Abstract
Proto-oncogenes, which represent the cellular progenitors of the transforming genes harbored by acute transforming oncogenic retroviruses, have been highly conserved during vertebrate evolution. In this report, we have assigned experimentally a subset of proto-oncogenes (SRC, ABL, FES, and FMS-all related to the SRC family) to Chinese hamster chromosomes by Southern filter hybridization analyses of DNAs isolated from both somatic cell hybrids and flow-sorted hamster chromosomes. These results demonstrate that several autosomal linkage groups containing proto-oncogenes originated prior to the radiation and speciation of mammals and have remained remarkably stable for nearly 80 million years.

Abstract
The striking number of human and murine immunodeficiency disorders which map to the X chromosome suggests that genes localized on this chromosome must have important roles in lymphocyte development. At least seven distinct disorders in the human and two in the mouse disrupt lymphocyte maturation, particularly that of B cells, at characteristic stages. As functional genes mapping to the X chromosome in one mammal are found on the X chromosome in all other mammals, the same genes regulating lymphocyte development are expected to be found on the X chromosome in mouse and man. Investigations into the possible mechanisms of these X-linked disorders have been hampered by the lack of molecular probes for the genes or gene products affected; because of this, and the possibility of correlating one or more of the several hundred B- or T-cell-specific genes with a specific mutation, we surveyed 15 different B- and T-cell-specific cDNA clones for localization to the X chromosome. We report here the characterization of one of these murine cDNA clones, which hybridizes with a large, X-linked gene family, designated XLR (X-linked, lymphocyte-regulated). We show that the XLR gene family is closely linked to the X-linked immunodeficiency described in the CBA/N mouse strain (xid), by restriction fragment length polymorphism (RFLP) analysis of DNA from mice congeneic for xid. This finding, together with data on the expression of the XLR locus in B cells, indicates that this gene family either includes the locus defined by the xid mutation or is adjacent to it in a gene complex which may be important in lymphocyte differentiation.

Abstract
Treatment of mice with the carcinogen N-methylnitrosourea results in the development of thymic lymphomas with frequent involvement of the N-ras oncogene. The activated mouse N-ras gene was isolated from one of these lymphomas and, by transformation in concert with restriction digestion, a map of the gene was prepared and its approximate boundaries were determined. By means of somatic cell hybrids the normal N-ras gene was found to be unlinked to other members of the ras gene family.

Abstract
Southern blot analysis of somatic cell hybrid lines indicates that the beta chain of the T cell receptor for antigen maps to chromosome 6 of the mouse. An experiment testing hybridization of the constant region of this gene to DNA from a hybrid cell line containing a translocation of chromosome 6 supports the localization of this gene to the proximal (centromeric) one-third of chromosome 6, in the same general region as the immunoglobulin kappa chain locus. This may be another indication of the shared evolutionary origins of the genes encoding both T and B cell antigen recognition.

Abstract
Avian erythroblastosis virus, a retrovirus that causes erythroblastosis and sarcomas in infected birds, possesses two host cell-derived genes [viral (v) erb-A and erb-B]. Although v-erb-B seems to be responsible for oncogenic transformation, v-erb-A might have an enhancing effect on transformation. In chickens, the natural host for avian erythroblastosis virus, cellular (c) erb-A and erb-B genes appear to be unlinked, but their chromosomal locations in other species are unknown. To ascertain the chromosomal location of c-erb genes in man and mouse, we analyzed interspecies somatic cell and microcell hybrids by Southern filter hybridization techniques using specific v-erb-A and v-erb-B probes. We found c-erb-A sequences on human chromosome 17 (17p11----qter) and located c-erb-B on human chromosome 7 (7pter----q22). In contrast, both c-erb-A and c-erb-B reside on mouse chromosome 11.

Abstract
Chromosome displays and listings are presented showing loci whose position is known in both man and mouse, in similar manner to our previous report (Dalton et al. 1981). There is now evidence for at least 27 conserved autosomal segments with two or more loci in the two species. The human and mouse chromosome maps show the location of homologous genes. The mouse map also shows the positions of translocations used in gene location and of some other genes used in linkage studies on them.

Abstract
It is hypothesized that oncogenic viruses (both RNA and DNA tumor viruses) use cellular differentiation switches as part of their mechanism for viral replication. Chemical or radiation-induced carcinogenesis is the result of mutations which also affect these differentiation switches and their cellular controls. A transformed cell is characterized by the uncontrolled and inappropriate expression of embryonic (developmental) sequences. Many of the oncogenic viruses, both RNA and DNA, are lineage- and stage-specific in the cells they can productively infect, in keeping with their means of replication. The interaction between virus and host cellular controls determines whether recognizable neoplasia will result from viral infection.

Abstract
Molecular probes for the oncogenes of Rous sarcoma virus (v-src), avian myeloblastosis virus (v-myb), Kirsten murine sarcoma virus (v-Ki-ras), and Harvey murine sarcoma virus (v-Ha-ras) were hybridized to the DNA from mouse-Chinese hamster somatic cell hybrids. The v-src, v-myb, v-Ki-ras, and v-Ha-ras genes each detected one or a few homologous mouse DNA fragments whose segregation was analyzed in cell hybrids. Mouse cellular homologs c-src, c-Ki-ras, c-Ha-ras, and c-myb segregated concordantly with chromosomes 2, 6, 7, and 10, respectively. Comparison with the known locations of human c-src (chromosome 20) and human c-Ha-ras1 (chromosome 11 short arm) suggests that the human and mouse homologs of these two viral oncogenes reside in conserved linkage groups. The c-Ki-ras gene on mouse chromosome 6 might reside also in a conserved linkage group, along with glyceraldehyde-3-phosphate dehydrogenase and triosephosphate isomerase. However, direct confirmation of this suggestion must await a demonstration that c-Ki-ras on mouse chromosome 6 is homologous to c-Ki-ras2 on the short arm of human chromosome 12.

Abstract
Chronic myeloid leukaemia (CML) cells are often characterized by the presence of a small chromosome 22, in which most of the q arm has been translocated to chromosome 9. Using cell hybrids containing different parts of chromosome 22 I have mapped the c-sis oncogene, which is known to be situated on chromosome 22, to a region distal to the CML breakpoint (22q112) and proximal to 22q13. This demonstrates that c-sis is translocated to chromosome 9 in CML cells.

Abstract
Two dozen cellular proto-oncogenes have been discovered to date through the study of retroviruses and the use of gene transfer. They form a structurally and functionally heterogeneous group. At least five distinct mechanisms are responsible for their conversion to active oncogenes. Recent work provides experimental strategies by which many of these oncogenes, as well as oncogenes of DNA tumor viruses, may be placed into functional categories. These procedures may lead to definition of a small number of common pathways through which the various oncogenes act to transform cells.

Abstract
A family of human transforming genes, previously shown to share homology with the ras family of viral oncogenes, maps to three different human chromosomes. A well-characterized mouse-human hybrid cell panel, combined with Southern blotting, was used in this study. The transforming gene of the T24 bladder carcinoma cell line maps to human chromosome 11. An oncogene isolated from the lung carcinoma cell line SK-Calu-1 maps to human chromosome 12. The third ras-related gene, cloned from SK-N-SH, a neuroblastoma cell line, maps to human chromosome 1.

Abstract
The utility of somatic cell genetic analysis for the chromosomal localization of genes in mammals is well established. With the development of recombinant DNA probes and efficient blotting techniques that allow visualization of single-copy cellular genes, somatic cell genetics has been extended from the level of phenotypes expressed by whole cells to the level of the cellular genome itself. This extension has proved invaluable for the analysis of genes not readily expressed in somatic cell hybrids and for the study of multigene families, especially pseudogenes dispersed in different chromosomes throughout the genome.
