A sequence-ready BAC clone contig of a 2.2-Mb segment of human chromosome 1q24. (1/1666)

Human chromosomal region 1q24 encodes two cloned disease genes and lies within large genetic inclusion intervals for several disease genes that have yet to be identified. We have constructed a single bacterial artificial chromosome (BAC) clone contig that spans over 2 Mb of 1q24 and consists of 78 clones connected by 100 STSs. The average density of mapped STSs is one of the highest described for a multimegabase region of the human genome. The contig was efficiently constructed by generating STSs from clone ends, followed by library walking. Distance information was added by determining the insert sizes of all clones, and expressed sequence tags (ESTs) and genes were incorporated to create a partial transcript map of the region, providing candidate genes for local disease loci. The gene order and content of the region provide insight into ancient duplication events that have occurred on proximal 1q. The stage is now set for further elucidation of this interesting region through large-scale sequencing.  (+info)

p73 at chromosome 1p36.3 is lost in advanced stage neuroblastoma but its mutation is infrequent. (2/1666)

p73, a novel p53 family member, is a recently identified candidate neuroblastoma (NBL) suppressor gene mapped at chromosome 1p36.33 and was found to inhibit growth and induce apoptosis in cell lines. To test the hypothesis that p73 is a NBL suppressor gene, we analysed the p73 gene in primary human NBLs. Loss of heterozygosity (LOH) for p73 was observed in 19% (28/151) of informative cases which included 92 mass-screening (MS) tumors. The high frequency of p73 LOH was significantly associated with sporadic NBLs (9% vs 34%, P<0.001), N-myc amplification (10% vs 71%, P<0.001), and advanced stage (14% vs 28%, P<0.05). Both p73alpha and p73beta transcripts were detectable in only 46 of 134 (34%) NBLs at low levels by RT-PCR methods, while they were easily detectable in most breast cancers and colorectal cancers under the same conditions. They found no correlation between p73 LOH and its expression levels (P>0.1). We found two mutations out of 140 NBLs, one somatic and one germline, which result in amino acid substitutions in the C-terminal region of p73 which may affect transactivation functions, though, in the same tumor samples, no mutation of the p53 gene was observed as reported previously. These results suggest that allelic loss of the p73 gene may be a later event in NBL tumorigenesis. However, p73 is infrequently mutated in primary NBLs and may hardly function as a tumor suppressor in a classic Knudson's manner.  (+info)

Homozygosity mapping to the USH2A locus in two isolated populations. (3/1666)

Usher syndrome is a group of autosomal recessive disorders characterised by progressive visual loss from retinitis pigmentosa and moderate to severe sensorineural hearing loss. Usher syndrome is estimated to account for 6-10% of all congenital sensorineural hearing loss. A gene locus in Usher type II (USH2) families has been assigned to a small region on chromosome 1q41 called the UHS2A locus. We have investigated two families with Usher syndrome from different isolated populations. One family is a Norwegian Saami family and the second family is from the Cayman Islands. They both come from relatively isolated populations and are inbred families suitable for linkage analysis. A lod score of 3.09 and 7.65 at zero recombination was reached respectively in the two families with two point linkage analysis to the USH2A locus on 1q41. Additional homozygosity mapping of the affected subjects concluded with a candidate region of 6.1 Mb. This region spans the previously published candidate region in USH2A. Our study emphasises that the mapped gene for USH2 is also involved in patients from other populations and will have implications for future mutation analysis once the USH2A gene is cloned.  (+info)

Characterization and mutation analysis of human LEFTY A and LEFTY B, homologues of murine genes implicated in left-right axis development. (4/1666)

Members of the transforming growth factor (TGF)-beta family of cell-signaling molecules have been implicated recently in mammalian left-right (LR) axis development, the process by which vertebrates lateralize unpaired organs (e.g., heart, stomach, and spleen). Two family members, Lefty1 and Lefty2, are expressed exclusively on the left side of the mouse embryo by 8.0 days post coitum. This asymmetry is lost or reversed in two murine models of abnormal LR-axis specification, inversus viscerum (iv) and inversion of embryonic turning (inv). Furthermore, mice homozygous for a Lefty1 null allele manifest LR malformations and misexpress Lefty2. We hypothesized that Lefty mutations may be associated with human LR-axis malformations. We now report characterization of two Lefty homologues, LEFTY A and LEFTY B, separated by approximately 50 kb on chromosome 1q42. Each comprises four exons spliced at identical positions. LEFTY A is identical to ebaf, a cDNA previously identified in a search for genes expressed in human endometrium. The deduced amino acid sequences of LEFTY A and LEFTY B are more similar to each other than to Lefty1 or Lefty2. Analysis of 126 human cases of LR-axis malformations showed one nonsense and one missense mutation in LEFTY A. Both mutations lie in the cysteine-knot region of the protein LEFTY A, and the phenotype of affected individuals is very similar to that typically seen in Lefty1-/- mice with LR-axis malformations.  (+info)

Evidence for a rare prostate cancer-susceptibility locus at chromosome 1p36. (5/1666)

Combining data from a genomic screen in 70 families with a high risk for prostate cancer (PC) with data from candidate-region mapping in these families and an additional 71 families, we have localized a potential hereditary PC-susceptibility locus to chromosome 1p36. Because an excess of cases of primary brain cancer (BC) have been observed in some studies of families with a high risk for PC, and because loss of heterozygosity at 1p36 is frequently observed in BC, we further evaluated 12 families with both a history of PC and a blood relative with primary BC. The overall LOD score in these 12 families was 3.22 at a recombination fraction (theta) of .06, with marker D1S507. On the basis of an a priori hypothesis, this group was stratified by age at diagnosis of PC. In the younger age group (mean age at diagnosis <66 years), a maximum two-point LOD score of 3.65 at straight theta = .0 was observed, with D1S407. This linkage was rejected in both early- and late-onset families without a history of BC (LOD scores -7.12 and -6.03, respectively, at straight theta = .0). After exclusion of 3 of the 12 families that had better evidence of linkage to previously described PC-susceptibility loci, linkage to the 1p36 region was suggested by a two-point LOD score of 4.74 at straight theta = .0, with marker D1S407. We conclude that a significant proportion of these families with both a high risk for PC and a family member with BC show linkage to the 1p36 region.  (+info)

Multipoint oligogenic analysis of age-at-onset data with applications to Alzheimer disease pedigrees. (6/1666)

It is usually difficult to localize genes that cause diseases with late ages at onset. These diseases frequently exhibit complex modes of inheritance, and only recent generations are available to be genotyped and phenotyped. In this situation, multipoint analysis using traditional exact linkage analysis methods, with many markers and full pedigree information, is a computationally intractable problem. Fortunately, Monte Carlo Markov chain sampling provides a tool to address this issue. By treating age at onset as a right-censored quantitative trait, we expand the methods used by Heath (1997) and illustrate them using an Alzheimer disease (AD) data set. This approach estimates the number, sizes, allele frequencies, and positions of quantitative trait loci (QTLs). In this simultaneous multipoint linkage and segregation analysis method, the QTLs are assumed to be diallelic and to interact additively. In the AD data set, we were able to localize correctly, quickly, and accurately two known genes, despite the existence of substantial genetic heterogeneity, thus demonstrating the great promise of these methods for the dissection of late-onset oligogenic diseases.  (+info)

Cloning and characterization of a lymphoid-specific, inducible human protein tyrosine phosphatase, Lyp. (7/1666)

Protein tyrosine phosphatases act in conjunction with protein kinases to regulate the tyrosine phosphorylation events that control cell activation and differentiation. We have isolated a previously undescribed human phosphatase, Lyp, that encodes an intracellular 105-kD protein containing a single tyrosine phosphatase catalytic domain. The noncatalytic domain contains four proline-rich potential SH3 domain binding sites and an NXXY motif that, if phosphorylated, may be recognized by phosphotyrosine binding (PTB) domains. Comparison of the Lyp amino acid sequence with other known proteins shows 70% identity with the murine phosphatase PEP. The human Lyp gene was localized to chromosome 1p13 by fluorescence in situ hybridization analysis. We also identified an alternative spliced form of Lyp RNA, Lyp2. This isoform encodes a smaller 85-kD protein with an alternative C-terminus. The lyp phosphatases are predominantly expressed in lymphoid tissues and cells, with Lyp1 being highly expressed in thymocytes and both mature B and T cells. Increased Lyp1 expression can be induced by activation of resting peripheral T lymphocytes with phytohemagglutinin or anti-CD3. Lyp1 was found to be constitutively associated with the proto-oncogene c-Cbl in thymocytes and T cells. Overexpression of lyp1 reduces Cbl tyrosine phosphorylation, suggesting that it may be a substrate of the phosphatase. Thus, Lyp may play a role in regulating the function of Cbl and its associated protein kinases.  (+info)

Genome-wide screen for systemic lupus erythematosus susceptibility genes in multiplex families. (8/1666)

Systemic lupus erythematosus (SLE) is the prototype of human autoimmune diseases. Its genetic component has been suggested by familial aggregation (lambdas = 20) and twin studies. We have screened the human genome to localize genetic intervals that may contain lupus susceptibility loci in a sample of 188 lupus patients belonging to 80 lupus families with two or more affected relatives per family using the ABI Prism linkage mapping set which includes 350 polymorphic markers with an average spacing of 12 cM. Non-parametric multipoint linkage analysis suggests evidence for predisposing loci on chromosomes 1 and 18. However, no single locus with overwhelming evidence for linkage was found, suggesting that there are no 'major' susceptibility genes segregating in families with SLE, and that the genetic etiology is more likely to result from the action of several genes of moderate effect. Furthermore, the support for a gene in the 1q44 region as well as in the 1p36 region is clearly found only in the Mexican American families with SLE but not in families of Caucasian ethnicity, suggesting that consideration of each ethnic group separately is crucial.  (+info)

Doheny doctors treat patients with retinal disease daily; and we also work continuously with colleagues around the world to find ways to fight these diseases. I want to share a few insights about one of those important efforts -a study of Stargardts Disease called ProgStar, sponsored by the Foundation Fighting Blindness.. ProgStar uses data sets from all over the world to analyze images and eye exam results in a quest to understand the rate of progression of Stargardts disease and how it can best be thwarted or eliminated. The data allows us to evaluate, and to better understand, how quickly the retina is deteriorating and how that decline is affecting visual acuity.. I am happy to let you know the Doheny Image Reading Center is the reading center for all of the data collected in the ProgStar study. Our work at the DIRC is integral to this critical research, and the meaning is significant: with adequate data, the launch of studies to test and approve drugs to treat Stargardts is ...

immune Uncategorized Rabbit Polyclonal to Integrin beta1, Tariquidar Oligodendroglial tumors form a definite subgroup of gliomas, seen as a an improved response to treatment and long term overall survival. marks ICIV). Gliomas exhibiting oligodendroglial features consist of oligodendrogliomas (WHO quality II) and anaplastic oligodendrogliomas (WHO quality III) aswell as oligoastrocytomas (WHO quality II), anaplastic oligoastrocytomas (WHO quality III) and glioblastomas with an oligodendroglial component (GBMO, WHO quality IV) [1]. Oligodendroglial tumors take into account 15-20% of most gliomas [2,3]. The recognition from the genes targeted by full 1p/19q co-deletion, a quality of oligodendrogliomas, is a long-standing Tariquidar search. Combined lack of entire chromosome hands 1p and 19q may be the most frequently recognized hereditary imbalance in oligodendroglial tumors, happening in 60-90% of oligodendrogliomas and 30-50% of oligoastrocytomas while they may be rarely within GBMO [4-6].

As a result, the 1p deletion is taken into account more and more in clinical trials and the management of patients. However, the laboratory technique implemented for detection of this biomarker has been a topic of debate.

The ZytoDot ® 2C SPEC 1p36/1q25 Probe is designed for the detection of 1p deletions by Chromogenic in situ Hybridization (CISH). Deletions affecting the short arm of chromosome 1 (1p) are frequently found in human gliomas and neuroblastomas, but also in breast, lung, endometrial, ovarian, and colorectal carcinomas. Loss of 1p is a strong prognostic factor in patients with neuroblastoma. Since loss of 1p reliably identifies patients at high risk in stages I, II, and IVS, which are otherwise clinically favorable, more aggressive therapy may be considered in these patients. Several studies showed correlation of combined allelic losses at 1p36 and 19q13 with oligodendroglioma histology and association with both chemotherapeutic response and survival in patients with anaplastic oligodendrogliomas. Hence, determination of 1p and 19q status may aid therapeutic decisions and predict outcome in patients with anaplastic oligodendrogliomas.

Stargardts disease (STGD) and Retinitis Pigmentosa (RP) are inherited retinal degenerations that may be affected, in opposite way, by diet. Dietary profile was assessed in 24 patients with STGD and in 56 patients with RP. We documented in only 6 out of 24 (25 %) STGD patients a daily intake of vitamin A within the recommended range while 14/24 (58.3 %) reported a high daily intake and 4/24 (16.7 %) showed a low daily intake. With regard to RP, 4/56 (7.1 %) reported to be within the recommended range, 37/56 (66.1 %) reported high daily intake and 15/56 (26.8 %) showed low daily intake of vitamin A. Interestingly, STGD patients with low vitamin A intake (|600 µg RAE/day) showed significantly better visual acuity with respect to those introducing higher intake of vitamin A. The present study suggests insuitable nutrient intakes among patients with STGD and RP, especially for daily intake of vitamin A. The results may be used to provide tailored nutritional interventions in these patients.
Anaplastic oligodendroglial tumors are rare neoplasms with no standard approach to treatment. We sought to determine patterns of treatment delivered over time and identify clinical correlates of specific strategies using an international retrospective cohort of 1013 patients diagnosed from 19812007. Prior to 1990, most patients received radiotherapy (RT) alone as initial postoperative treatment. After 1990, approximately 50 of patients received both RT and chemotherapy (CT) sequentially and/or concurrently. Treatment with RT alone became significantly less common (67 in 19801984 vs 5 in 20052007, P | .0001). CT alone was more frequently administered in later years (0 in 19801984 vs 38 in 20052007; P | .0001), especially in patients with 1p19q codeleted tumors (57 of codeleted vs 4 with no deletion in 20052007; P | .0001). Temozolomide replaced the combination of procarbazine, lomustine, and vincristine (PCV) among patients who received CT alone or with RT (87 vs 2 in 20052007). In the most recent time
Meningiomas are mostly benign brain tumours, with a potential for becoming atypical or malignant. On the basis of comprehensive genomic, transcriptomic and epigenomic analyses, we compared benign meningiomas to atypical ones. Here, we show that the majority of primary (de novo) atypical meningiomas display loss of NF2, which co-occurs either with genomic instability or recurrent SMARCB1 mutations. These tumours harbour increased H3K27me3 signal and a hypermethylated phenotype, mainly occupying the polycomb repressive complex 2 (PRC2) binding sites in human embryonic stem cells, thereby phenocopying a more primitive cellular state. Consistent with this observation, atypical meningiomas exhibit upregulation of EZH2, the catalytic subunit of the PRC2 complex, as well as the E2F2 and FOXM1 transcriptional networks. Importantly, these primary atypical meningiomas do not harbour TERT promoter mutations, which have been reported in atypical tumours that progressed from benign ones. Our results ...
Clinical management of grade III oligodendroglioma G Simonetti, P Gaviani, A Botturi, A Innocenti, E Lamperti, A Silvani Neurooncology Unit, Fondazione IRCCS Istituto Neurologico Carlo Besta, Milan, Italy Abstract: Oligodendrogliomas represent the third most common type of glioma, comprising 4%–15% of all gliomas and can be classified by degree of malignancy into grade II and grade III, according to WHO classification. Only 30% of oligodendroglial tumors have anaplastic characteristics. Anaplastic oligodendroglioma (AO) is often localized as a single lesion in the white matter and in the cortex, rarely in brainstem or spinal cord. The management of AO is deeply changed in the recent years. Maximal safe surgical resection followed by radiotherapy (RT) was considered as the standard of care since paramount findings regarding molecular aspects, in particular co-deletion of the short arm of chromosome 1 and the long arm of chromosome 19, revealed that these subsets of AO, benefit in terms of overall

Definition : Molecular assay reagents intended to identify mutations in the ATP-binding cassette, subfamily A (ABC1), member 4 (ABCA4) gene, located at chromosome 1p22.1-p21, which encodes for a membrane-associated protein that is a member ATP-binding cassette (ABC) transporter. ABC proteins transport various molecules across extra- and intracellular membranes. Mutations at this locus have been identified in patients with retinitis pigmentosa type 19 (RP19), Stargardts disease, and age-related macular degeneration..

OPINION STATEMENT: Anaplastic oligodendroglial tumors have gained increasing interest with the emerging role of molecular markers and systemic chemotherapy during the past years. The long-term results of two landmark trials, RTOG 9402 and EORTC 26961, have resulted in a reconsideration of the appropriate therapeutic approaches for patients with these tumors. Both trials indicate that patients whose tumors harbor a 1p/19q co-deletion benefit particularly from the addition of procarbazine/lomustine (CCNU)/vincristine (PCV) chemotherapy to radiation therapy (RT). The median survival of patients with co-deleted tumors treated within the RTOG trial with PCV before irradiation was 14.7 years compared with 7.3 years of patients who received RT alone. Median overall survival has not been reached in the RT plus PCV arm of the EORTC trial, but a similar difference can be anticipated after a follow-up of more than 12 years. In contrast, no such benefit was observed for patients with tumors lacking 1p/19q ...
Mixed gliomas, such as oligoastrocytomas (OA), anaplastic oligoastrocytomas, and glioblastomas (GBMs) with an oligodendroglial component (GBMO) are defined as tumors composed of a mixture of two distinct neoplastic cell types, astrocytic and oligodendroglial. Recently, mutations ATRX and TP53, and codeletion of 1p/19q are shown to be genetic hallmarks of astrocytic and oligodendroglial tumors, respectively. Subsequent molecular analyses of mixed gliomas preferred the reclassification to either oligodendroglioma or astrocytoma. This study was designed to apply genetically integrated diagnostic criteria to mixed gliomas and determine usefulness and prognostic value of new classification in Korean patients ...
OBJECTIVES: I. Compare survival and time to first progression in patients with anaplastic oligodendroglioma treated with radiotherapy with or without adjuvant procarbazine, lomustine, and vincristine (PCV) following surgical resection. II. Investigate the effect of PCV on quality of life and neurologic function in these patients. III. Determine the toxicity of PCV in these patients. IV. Correlate chromosomal lesions (1p and/or 19q, 9p, p53 loss and mutation, amplification of chromosome 7, or loss of chromosome 10) with progression-free and overall survival in patients treated with these regimens.. OUTLINE: This is a randomized, multicenter study. Patients are stratified according to age, extent of resection, performance status, prior surgery, and participating center. Patients are randomized to one of two treatment arms. Arm I: Within 4-6 weeks after surgery, patients undergo radiotherapy over 7 weeks to the residual tumor volume. Arm II: Patients undergo radiotherapy as in arm I, then begin ...

These two tumour types comprise approximately one quarter of all gliomas with astrocytomas taking up the other three quarters.. What is the prognosis of patients with oligodendrogliomas? Oligodendrogliomas tend to be diagnosed more often than ependemyomas. The prognosis of patients with oliogodendrogliomas is better overall than that of patients with astrocytomas, however it worsens if the tumour progresses to the anaplastic stage. The evolution of oligodendrogliomas is similar to that of astrocytomas. If the tumour is caught in time, and treated, via means of surgery, the patient may be able to live up to ten years, and have a median survival rate of 5 years.. What do oligodendrogliomas appear like on the macroscopic and microscopic level? ...
Loss of heterozygosity (LOH) of the short arm of chromosome 1 (1p) and the long arm of chromosome 19 (19q) is an early event in oligodendroglioma that occurs in up to 80% of patients and is associated with therapeutic sensitivity and longer overall survival. The purpose of this study was to confirm the reported association in patients at this centre, then identify and characterise genes that were differentially expressed and may function as a tumour suppressor or contribute to therapeutic sensitivity in oligodendroglioma. A clinical review of oligodendroglioma patients treated at Royal North Shore and North Shore Private Hospitals between 1990 and 2009 confirmed the association between LOH 1p/19q and longer overall survival in WHO grade III oligodendroglioma patients. Younger age and lower tumour grade were additionally confirmed as positive prognostic factors. Exon microarrays were used to identify changes in gene expression between oligodendrogliomas with and without LOH 1p/19q. Seventeen ...
Oligoastrocytoma are diffusely growing glioma, that belong to the oligodendroglial tumours.

SUAREZ, Julio César et al. Gliomas cerebrales de bajo grado en el adulto. Rev. argent. neurocir. [online]. 2008, vol.22, n.1. ISSN 1850-1532.. Objective. Gliomas reviewed in this article are grade II tumors according to the World Health Organization (WHO), that include: fibrillary and protoplasmic astrocytomas, oligodendrogliomas and oligoastrocytomas or mix tumors (1,2,3).Low grade astrocytomas constitute 15% of brain tumors in adults, while low grade oligodendrogliomas represent 4% (2,4). We present our experience with this type of tumor operated on between January 1972 and December 2006. Material and Method. The clinical reports of 25 patients with this type of tumor were analyzed, 15 women and 10 men, which represent 15,6% of hemispheric brain gliomas in adults in our series. Results. Fifteen were fibrillary astrocytomas, 8 oligodendrogliomas and 2 oligoastrocytomas. Treatment depended on tumor localization and size. Surgery and radiotherapy were the therapeutic modalities most frequently ...

Sixty-three of 100 patients had enhancing tumors at initial presentation. Presence of contrast enhancement at diagnosis was related to reduced TTR and OS on univariate analysis but was not significantly related on multivariate analysis. In enhancing tumors, however, greater initial volume of enhancing tissue correlated with shortened TTR (p = 0.00070). Reduced postoperative residual enhancing volume and a relatively greater resection of enhancing tissue correlated with longer OS (p = 0.0012 and 0.0041, respectively). Interestingly, patients in whom 100% of enhancing tumor was resected had significantly longer TTR (174 vs 64 weeks) and OS (392 vs 135 weeks) than those with any residual enhancing tumor postoperatively. This prognostic benefit was not consistently maintained with greater than 90% or even greater than 95% resection of enhancing tissue. There was no relationship between presence or volume of enhancement and del 1p/19q. ...
Stargardts disease (STGD), also known as fundus flavimaculatus (FFM), is an autosomal recessive retinal disorder characterized by a juvenile-onset macular dystrophy, alterations of the peripheral retina, and subretinal deposition of lipofuscin-like material. A gene encoding an ATP-binding cassette (ABC) transporter was mapped to the 2-cM (centiMorgan) interval at 1p13-p21 previously shown by linkage analysis to harbor the STGD gene. This gene, ABCR, is expressed exclusively and at high levels in the retina, in rod but not cone photoreceptors, as detected by in situ hybridization. Mutational analysis of ABCR in STGD families revealed a total of 19 different mutations including homozygous mutations in two families with consanguineous parentage. These data indicate that ABCR is the causal gene of STGD/FFM ...
Our primary finding for linkage to diabetic nephropathy is on chromosome 19q (triangle MLS = 3.1), with a secondary peak on chromosome 2q (triangle MLS = 2.1). The former, but not the latter, exceeds the Lander and Kruglyak criterion of triangle MLS ≥2.6 (17,18) for suggestive linkage. For reference, triangle MLS values of 3.3, 2.3, and 1.7 correspond to unadjusted P values of 0.0001, 0.001, and 0.005, respectively.. Stratification of DSPs based on proteinuria or ESRD suggested four tertiary peaks: linkage with ESRD on chromosome 1q (MLS = 1.8), linkage with proteinuria on chromosome 20p (MLS = 2.8), and linkage with two separate regions on chromosome 3q, one for proteinuria (MLS = 1.5) and another, 58 cM away, for ESRD (MLS = 1.1). We also found two chromosomal regions linked with type 1 diabetes. The most striking, not surprisingly, was on chromosome 6p (MLS = 9.2, 52 cM), confirming the well-established linkage with HLA. We also replicated IDDM15 on chromosome 6q (MLS = 3.1, 142 cM) ...
This is my first post as well so I will give you a little background first. I was diagnosed in September of 2003 with a grade II mixed Oligodendroglioma. I was given the option of doing nothing and taking a wait and see approach or being more aggressive and attempting to remove as much as possible with surgery. I chose the surgery option and they were able to remove about 2/3 of the tumor from my left frontal lobe. While I was on the table the surgeon spoke to my family and told them he could try to get the rest but he would have to remove so much good brain tissue that damage was likely and there was a large risk of me coming out of the surgery a different person. Fortunately my family made the right decision and decided against any further removal. I started Temodar in December of 2003 and continued that until February of 2006 with a lapse due to the onset of some severe side effects that required stopping treatment for about 4-5 months. My doctors were going to do radiation therapy but at the ...
