Abstract
BACKGROUND Substance use remains a barrier to recovery for young people accessing early intervention services for psychosis. While correlates of use have been explored in populations experiencing a first episode of psychosis (FEP), sample sizes have been small and less research assesses cohorts at ultrahigh risk of psychosis (UHR). METHODS This study uses data from a naturalistic cohort including UHR and FEP participants (N = 1252) to elucidate clinical correlates of use in the past 3 months of any illicit substance, amphetamine-type stimulants (ATS), cannabis, and tobacco. Moreover, network analysis based on use of these substances and additionally alcohol, cocaine, hallucinogens, sedatives, inhalants, and opioids was completed. RESULTS Young people with FEP used substances at significantly higher rates than those at UHR. High concurrence of use was seen between substances. In the FEP group, participants who had used any illicit substance, ATS, and/or tobacco had increased positive symptoms and decreased negative symptoms. Young people with FEP who used cannabis had increased positive symptoms. In the UHR group, participants who had used any illicit substance, ATS, and/or cannabis in the past 3 months showed decreased negative symptoms compared to those who had not. CONCLUSION A distinct clinical picture of more florid positive symptoms and alleviated negative symptoms seen in those who use substances in the FEP group appears muted in the UHR cohort. Treating young people at UHR in early intervention services represents the earliest opportunity to address substance use early to improve outcomes.

Abstract
Cytogenomic investigations of haematological neoplasms, including chromosome banding analysis, fluorescence in situ hybridisation (FISH) and microarray analyses have become increasingly important in the clinical management of patients with haematological neoplasms. The widespread implementation of these techniques in genetic diagnostics has highlighted the need for guidance on the essential criteria to follow when providing cytogenomic testing, regardless of choice of methodology. These recommendations provide an updated, practical and easily available document that will assist laboratories in the choice of testing and methodology enabling them to operate within acceptable standards and maintain a quality service.

Abstract
Deletion of the long arm of chromosome 15 has been described as a recurrent chromosomal abnormality in myeloid malignancies. We present here some additional case reports of deletion 15 including two cases with an extra copy of the deleted chromosome, a finding that has not previously been described. We compare our cases to those previously reported. Our findings show that, contrary to previous reports, this abnormality may not always be associated with an unfavorable prognosis. They also indicate that deletion 15q most frequently appears to be associated with myelomonocytic disease. Potential candidate genes on 15q that may be involved in the tumorigenesis of these cases are discussed.

Abstract
Chronic myeloid leukemia (CML) is characterized by formation of the BCR-ABL fusion gene, usually as a consequence of the Philadelphia (Ph) translocation between chromosomes 9 and 22. Large deletions on the derivative chromosome 9 have recently been reported, but it was unclear whether deletions arose during disease progression or at the time of the Ph translocation. Fluorescence in situ hybridization (FISH) analysis was used to assess the deletion status of 253 patients with CML. The strength of deletion status as a prognostic indicator was then compared to the Sokal and Hasford scoring systems. The frequency of deletions was similar at diagnosis and after disease progression but was significantly increased in patients with variant Ph translocations. In patients with a deletion, all Ph(+) metaphases carried the deletion. The median survival of patients with and without deletions was 38 months and 88 months, respectively (P =.0001). By contrast the survival difference between Sokal or Hasford high-risk and non-high-risk patients was of only borderline significance (P =.057 and P =.034). The results indicate that deletions occur at the time of the Ph translocation. An apparently simple reciprocal translocation may therefore result in considerable genetic heterogeneity ab initio, a concept that is likely to apply to other malignancies associated with translocations. Deletion status is also a powerful and independent prognostic factor for patients with CML. The prognostic significance of deletion status should now be studied prospectively and, if confirmed, should be incorporated into management decisions and the analysis of clinical trials.

Abstract
The MLL gene, located at 11q23, is frequently rearranged in acute leukaemia as either chimaeric fusion genes or partial tandem duplications. We report a series of 12 acute leukaemia cases with apparent amplification of the MLL gene ascertained using fluorescence in situ hybridisation (FISH). Seven cases showed intrachromosomal amplification of MLL, four cases showed extrachromosomal amplification as double minute chromosomes (dmin) and one case had separate subclones with dmin and homogenously staining region (hsr). Southern blot analysis of the MLL gene showed MLL gene rearrangement in three of the 10 successful cases. These cases do not naturally fall into either of the two recognised categories of MLL rearrangement and may represent a third variety of MLL gene abnormalities.

A case of extraskeletal myxoid chondrosarcoma (EMC) in which there was histochemical, immunohistochemical, and ultrastructural evidence of neuroendocrine differentiation is reported. Genetic investigations showed the recently described novel translocation t(9;17)(q22;q11.2) and associated fusion of the CHN and RBP56 genes, contrasting with the translocation t(9;22)(q22;q12) and EWS/CHN gene fusion found in the majority of EMCs.

Abstract
The consistent dysregulation of HLA expression in cervical neoplasia is likely to influence the natural history of the disease and prospects for cell-mediated vaccine therapies. We have studied the underlying mechanisms in eight new cervical cancer cell lines derived from primary tumour biopsies. At least five independent mechanisms leading to changes in HLA expression were seen: HLA class I allelic transcription but no protein; abnormal HLA class I allelic transcription; no HLA-B locus transcription; loss of heterozygosity (LOH); no gammaIFN-mediated upregulation of HLA class I expression, and/or no interferon-gamma (gammaIFN)-mediated HLA class II induction. These were evident in different combinations in 7/8 cell lines showing that multiple, mostly irreversible mechanisms not overridden by gammaIFN, are responsible for HLA dysregulation in cervical neoplasia. Point mutations were responsible for lack of HLA-A2 expression in two cases. In cell line 808, the mutation encodes a stop codon in exon 3; in cell line 778, mutation of the first intron acceptor site leads to use of an alternative AG site in exon 2, resulting in a frameshift and a stop codon after the translation of only 38 amino acids. Tumour cells showing specific HLA class I loss may have selective advantage in the face of tumour-specific cytotoxic T cells (CTL). Such immune escape mechanisms present a major obstacle for the success of CTL-mediated therapies in cervical cancer.

Abstract
The hallmark of chronic myeloid leukemia (CML) is the BCR-ABL fusion gene, which is usually formed as a result of the t(9;22) translocation. Patients with CML show considerable heterogeneity both in their presenting clinical features and in the time taken for evolution to blast crisis. In this study, metaphase fluorescence in situ hybridization showed that a substantial minority of patients with CML had large deletions adjacent to the translocation breakpoint on the derivative 9 chromosome, on the additional partner chromosome in variant translocations, or on both. The deletions spanned up to several megabases, had variable breakpoints, and could be detected by microsatellite polymerase chain reaction in unfractionated bone marrow and purified peripheral blood granulocytes. The deletions were likely to occur early and possibly at the time of the Philadelphia (Ph) chromosome translocation: deletions were detected at diagnosis in 11 patients, were found in all Ph-positive metaphases, and were more prevalent in patients with variant Ph chromosomes. Kaplan-Meier analysis showed a median survival time of 36 months in patients with a deletion; patients without a detectable deletion survived > 90 months. The survival-time difference was significant on log-rank analysis (P =. 006). Multivariate analysis demonstrated that the prognostic importance of deletion status was independent of age, sex, percentage of peripheral blood blasts, and platelet count. Our data therefore suggest that an apparently simple, balanced translocation may result not only in the generation of a dominantly acting fusion oncogene but also in the loss of one or more genes that influence disease progression.

Abstract
A proportion of extraskeletal myxoid chondrosarcomas (EMC) have been shown to have a characteristic translocation t(9;22)(q22;q12) involving the EWS gene at 22q12 and the CHN orphan nuclear receptor gene at 9q22. This translocation appears to be largely specific for EMC, but has not been detected in all such tumours. We report here a case of EMC with a t(9;17)(q22;q11.2) as the sole chromosome abnormality. We have determined that the translocation results in the fusion of the entire coding region of CHN to the N-terminal transactivation domain of RBP56/hTAFII68. This is the first report of a translocation involving RBP56/hTAFII 68, a protein with sequence homology to both EWS and TLS/FUS. The involvement of RBP56/hTAFII68 may explain some unusual features of the tumour.

Abstract
The clonogenic cells of chronic myeloid leukaemia (CML), unlike normal haemopoietic colony forming cells (CFC), are resistant to the growth inhibitory effects of the chemokine, macrophage inflammatory protein-1alpha (MIP-1alpha). Here, we tested the hypothesis that MIP-1alpha protects normal, but not CML, CFC from the cytotoxic effects of the cell-cycle active drug cytosine arabinoside (Ara-C). Using a 24-h Ara-C protection assay we showed that MIP-1alpha confers protection to normal CFC but also sensitizes CML CFC to Ara-C. The differential MIP-1alpha responsiveness was not due to a down-regulation of MIP-1alpha receptors on CML CD34+ cells as flow cytometric analysis showed similar binding of a biotinylated MIP-1alpha molecule to normal and CML CD34+ cells. Flow cytometric analysis of the MIP-1alpha receptor subtype CCR-5 revealed comparable CCR-5 expression levels on normal and CML CD34+ cells. Furthermore, culture of CD34+ cells for 10 h in the presence of TNF-alpha resulted in an increased MIP-1alpha receptor expression on both normal and CML CD34+ cells. Our data suggest that the unresponsiveness of CML CFC to the growth inhibitory effect of MIP-1alpha is not caused by a lack of MIP-1alpha receptor or total uncoupling of the MIP-1alpha responsiveness but may be due to an intracellular signalling defect downstream of the receptors.

Abstract
Abnormalities of chromosome band 13q14 occur in hematologic malignancies of all lineages and at all stages of differentiation. Unlike other chromosomal translocations, which are usually specific for a given lineage, the chromosomal translocation t(12;13)(p12;q14) has been observed in both B-cell and T-cell precursor acute lymphoblastic leukemia (BCP-, TCP-ALL), in differentiated and undifferentiated acute myeloblastic leukemia (AML), and in chronic myeloid leukemia (CML) at progression to blast crisis. The nature of these translocations and their pathologic consequences remain unknown. To begin to define the gene(s) involved on chromosome 13, we have performed fluorescence in situ hybridization (FISH) using a panel of YACs from the region, on a series of 10 cases of acute leukemia with t(12;13)(p12;q14) and 1 case each with "variant" translocations including t(12;13)(q21;q14), t(10;13)(q24;q14) and t(9;13)(p21;q14). In 8/13 cases/cell lines, the 13q14 break fell within a single 1.4 Mb CEPH MegaYAC. This YAC fell immediately telomeric of the forkhead (FKHR) gene, which is disrupted in the t(2;13)(q35;q14) seen in pediatric alveolar rhabdomyosarcoma. Seven of the 8 cases with breaks in this YAC were AML. In 4/13 cases, the 13q14 break fell within a 1.7-Mb YAC located about 3 Mb telomeric of the retinoblastoma (RB1) gene: all 4 cases were ALL. One case of myelodysplastic syndrome exhibited a break within 13q12, adjacent to the BRCA2 gene. These data indicate the presence of myeloid- and lymphoid-specific breakpoint cluster regions within chromosome band 13q14 in acute leukemia.

Abstract
We report a case of a male infant who presented with congenital anomalies and was found to have a de novo deletion in the terminal region of the long arm of chromosome 9. He died at the age of 17 weeks of cardiorespiratory failure owing to RSV positive bronchiolitis. A review of previously published reports documented one previous report of a patient with a deletion of (9)(q34.3) and multiple congenital anomalies. Comparison with the previously reported case suggests that the phenotype observed constitutes a clinically recognisable pattern of malformations.

Abstract
A female infant is described with hypoglycaemia, hypotonia, obesity of the trunk and thighs, and mild dysmorphic features. Growth parameters were consistently above the 90th centile. Chromosome analysis showed her to have a derived chromosome 9 inherited from a maternal t(3;9)(p25;p23) by adjacent I segregation. She had features in common with both the dup(3p) and del(9p) syndromes. There are few reports of this chromosome rearrangement and the features are milder than expected for the degree of imbalance, complicated in males by sex reversal. The repeated reports of macrosomia may suggest an overgrowth syndrome.

Abstract
Age-sensitive neurochemical measures and estrous cyclicity were studied in female mice from the long-lived C3B10F1 strain fed either a control diet or subjected to dietary restriction (DR) from 3 weeks of age. Striatal dopaminergic D2 receptor density decreased by 25% from 9-10 months to 28-30 months of age in the control group. This decline was uninfluenced by DR. Anterior pituitary dopamine + dihydroxyphenylacetic acid content increased by 2.5 fold with age in the control group but DR failed to oppose this age-related change. In contrast to DR's lack of influence on these two neurochemical measures were findings on estrous cyclicity. Although mice on DR did not display estrous cycles, cyclicity was rapidly initiated when these mice were switched to the control diet at 12 and even at 22 months of age. Thus, limited aspects of neuroendocrine aging were retarded by DR in this long-lived mouse model.

Abstract
DOPA was measured in the anterior pituitary and hypothalamic-hypophysial portal blood after treatment with NSD-1015, a DOPA decarboxylase inhibitor. NSD-1015 caused DOPA to accumulate in the anterior pituitary of mice and rats, and increased DOPA in the hypothalamic-hypophysial portal blood of rat. Serum prolactin was also increased. Interruption of the anterior pituitary blood supply from the hypothalamic-hypophysial system by cannulation of the entire pituitary stalk eliminated the NSD-1015-induced DOPA accumulation in the rat pituitary. We conclude that DOPA can be taken into the anterior pituitary from the portal blood of NSD-1015-treated rodents and that the anterior pituitary lacks tyrosine hydroxylase activity in both mice and rats.

Abstract
A mildly dysmorphic, 2 year old girl with mental retardation was found to have a small de novo terminal deletion of the long arm of chromosome 14, del(14)(q32.3). She was found to have features in common with two previous terminal deletion cases and particularly with the well documented ring 14 syndrome, although seizures, a characteristic feature of ring 14, were notably absent.

Abstract
The effects of aging and estradiol on the three major hypothalamic monoaminergic systems were measured in female C57BL/6J mice. Both aging and estradiol treatment induced small (10-15%) changes in the levels and ratios of the monoamines and their catabolites. In addition, the levels of 5-hydroxyindoleacetic acid, the major serotonergic catabolite, were strongly correlated with the levels of the two major dopaminergic catabolites, 3,4-dihydroxyphenylacetic acid and homovanillic acid. Aging affected the relationship between 5-hydroxyindoleacetic acid and the dopaminergic catabolites such that the slope of the regression lines of 5-hydroxyindoleacetic acid on the dopaminergic compounds was increased in older mice. The age-related alteration in the correlations between the serotonergic and dopaminergic compounds may be due to an effect of aging on the acid export system.

Abstract
Estradiol (E2) produces many-fold increases in the dopamine (DA) content of the anterior pituitary and also plays a role in the age-related increase in pituitary DA in female C57BL/6J mice. These studies address the following questions: (1) What are the time and dose characteristics of the E2-induced increase in pituitary DA and can other gonadal steroids - such as progesterone (P) and 5 alpha-dihydrotestosterone - also influence pituitary DA? (2) Is the age-related increase in pituitary DA due entirely to an increase in the E2:P ratio seen in aging female mice, or can extra-ovarian factors also play a role? (3) Is the E2-induced (and therefore possibly the age-related) increase in pituitary DA secondary to an E2-induced increase in serum prolactin? In ovariectomized (OVX) mice, E2 implants increased pituitary DA in a time- and dose-dependent fashion. P implants administered to OVX mice simultaneously with E2 antagonized the E2-induced increase in pituitary DA. Daily injections of 5 alpha-dihydrotestosterone given in conjunction with E2 implants had no effect on basal or E2-increased pituitary DA in OVX mice. Thus, E2 is the only gonadal steroid examined which increases anterior pituitary DA. In intact aging mice, P attenuates the age-related increase in pituitary DA, supporting the hypothesis that the increased ratio of E2:P secreted by the ovaries of aging female mice is responsible for the age-related increase in pituitary DA. However, at advanced ages, intact male mice also showed modest increases in anterior pituitary DA.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
We describe how the increase of anterior pituitary dopamine (DA) during aging in female mice is related to altered secretion of ovarian steroids during reproductive senescence. A number of age-correlated neuroendocrine changes in female rodents result from cumulative exposure to ovarian steroids over a lifetime of estrous cycles, or from the altered pattern of ovarian steroid secretion concomitant with reproductive senescence. Pituitary DA has been shown to increase with age in female rats. To examine how the age-correlated increase of pituitary DA may depend on estradiol (E2), we measured pituitary DA and serum prolactin (PRL) in the following groups of female mice: young (7 months) cycling, middle-aged (14 months) cycling and non-cycling, old (17 months) non-cycling, old (17 months) ovariectomized (OVX) at 4 months, and young mice given 0.2 mg E2 valerate or E2 implants. Mice from some of these groups were OVX 1, 4 or 8 weeks before sacrifice. Compared with young controls, 14-month-old cycling or non-cycling mice had 3-fold higher pituitary DA, and 17-month-old non-cycling mice had 5-fold higher pituitary DA. OVX for 2 or 13 months before sacrifice abolished the effect of age; OVX of young mice had no effect on pituitary DA. Three weeks after implantation of E2 into OVX young mice or 7 weeks after injection of E2 valerate in intact young mice, pituitary DA was elevated. The E2-sensitive fraction of pituitary DA does not appear to decrease PRL secretion.(ABSTRACT TRUNCATED AT 250 WORDS)
