Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.

Superimposed histologic and genetic mapping of chromosome 9 in progression of human urinary bladder neoplasia: implications for a genetic model of multistep urothelial carcinogenesis and early detection of urinary bladder cancer. (1/1281)

The evolution of alterations on chromosome 9, including the putative tumor suppressor genes mapped to the 9p21-22 region (the MTS genes), was studied in relation to the progression of human urinary bladder neoplasia by using whole organ superimposed histologic and genetic mapping in cystectomy specimens and was verified in urinary bladder tumors of various pathogenetic subsets with longterm follow-up. The applicability of chromosome 9 allelic losses as non-invasive markers of urothelial neoplasia was tested on voided urine and/or bladder washings of patients with urinary bladder cancer. Although sequential multiple hits in the MTS locus were documented in the development of intraurothelial precursor lesions, the MTS genes do not seem to represent a major target for p21-23 deletions in bladder cancer. Two additional tumor suppressor genes involved in bladder neoplasia located distally and proximally to the MTS locus within p22-23 and p11-13 regions respectively were identified. Several distinct putative tumor suppressor gene loci within the q12-13, q21-22, and q34 regions were identified on the q arm. In particular, the pericentromeric q12-13 area may contain the critical tumor suppressor gene or genes for the development of early urothelial neoplasia. Allelic losses of chromosome 9 were associated with expansion of the abnormal urothelial clone which frequently involved large areas of urinary bladder mucosa. These losses could be found in a high proportion of urothelial tumors and in voided urine or bladder washing samples of nearly all patients with urinary bladder carcinoma.  (+info)

Level of retinoblastoma protein expression correlates with p16 (MTS-1/INK4A/CDKN2) status in bladder cancer. (2/1281)

Recent studies have shown that patients whose bladder cancer exhibit overexpression of RB protein as measured by immunohistochemical analysis do equally poorly as those with loss of RB function. We hypothesized that loss of p16 protein function could be related to RB overexpression, since p16 can induce transcriptional downregulation of RB and its loss may lead to aberrant RB regulation. Conversely, loss of RB function has been associated with high p16 protein expression in several other tumor types. In the present study RB negative bladder tumors also exhibited strong nuclear p16 staining while each tumor with strong, homogeneous RB nuclear staining were p16 negative, supporting our hypothesis. To expand on these immunohistochemical studies additional cases were selected in which the status of the p16 encoding gene had been determined at the molecular level. Absent p16 and high RB protein expression was found in the tumors having loss of heterozygosity within 9p21 and a structural change (mutation or deletion) of the remaining p16 encoding gene allele, confirming the staining results. These results strongly support the hypothesis that the RB nuclear overexpression recently associated with poor prognosis in bladder cancer is also associated with loss of p16 function and implies that loss of p16 function could be equally deleterious as RB loss in bladder and likely other cancers.  (+info)

Diaphyseal medullary stenosis with malignant fibrous histiocytoma: a hereditary bone dysplasia/cancer syndrome maps to 9p21-22. (3/1281)

Diaphyseal medullary stenosis with malignant fibrous histiocytoma (DMS-MFH) is an autosomal dominant bone dysplasia/cancer syndrome of unknown etiology. This rare hereditary cancer syndrome is characterized by bone infarctions, cortical growth abnormalities, pathological fractures, and eventual painful debilitation. Notably, 35% of individuals with DMS develop MFH, a highly malignant bone sarcoma. A genome scan for the DMS-MFH gene locus in three unrelated families with DMS-MFH linked the syndrome to a region of approximately 3 cM on chromosome 9p21-22, with a maximal two-point LOD score of 5.49 (marker D9S171 at recombination fraction [theta].05). Interestingly, this region had previously been shown to be the site of chromosomal abnormalities in several other malignancies and contains a number of genes whose protein products are involved in growth regulation. Identification of this rare familial sarcoma-causing gene would be expected to simultaneously define the cause of the more common nonfamilial, or sporadic, form of MFH-a tumor that constitutes approximately 6% of all bone cancers and is the most frequently occurring adult soft-tissue sarcoma.  (+info)

Identification and characterization of a homozygous deletion found in ovarian ascites by representational difference analysis. (4/1281)

We have performed representational difference analysis (RDA) on DNA from tumor cells and normal fibroblasts isolated from the ascites of a patient with ovarian cancer. Five of six products of the RDA were homozygously deleted from the tumor DNA. One of these products has been characterized and identifies a homozygous deletion of approximately 6.9 Mb at chromosome 9p21 in the original ovarian tumor material. This deletion encompasses CDKN2A (p16), CDKN2B (p15), and IFN-alpha. PCR analysis of other tumor cell lines using the novel STS based on the RDA product has shown it to lie between IFN-alpha and p16, and to identify the distal extent of a homozygous deletion in another ovarian cancer cell line. These data provide further evidence for a tumor suppressor locus distinct from, but mapping close to, p16 on 9p21. Cytogenetic analysis using comparative genomic hybridization (CGH) performed on the same primary tumor confirmed a loss of material from chromosome 9p. However, the CGH technique had neither the resolution nor the sensitivity to define a subregion of homozygous loss.  (+info)

Frequent genetic alterations in simple urothelial hyperplasias of the bladder in patients with papillary urothelial carcinoma. (5/1281)

In order to understand the origin of bladder cancer, very early urothelial lesions must be investigated in addition to more advanced tumors. Tissue from 31 biopsies of 12 patients with urothelial hyperplasias and simultaneous or consecutive superficial papillary tumors were used to microdissect urothelium from 15- microm sections of biopsies. The biopsies were obtained with the recently developed highly sensitive diagnostic method of 5-aminolevulinic acid-induced fluorescence endoscopy (AFE). Besides flat and papillary urothelial neoplasms, the method of photodynamic diagnostics also detects simple urothelial hyperplasias as fluorescent positive lesions. In addition, 12 fluorescence-positive biopsies showing histologically normal urothelium were investigated. Fluorescence in situ hybridization was done using a dual color staining technique of biotinylated centromeric probes of chromosomes 9 and 17 and digoxigenin-labeled gene-specific P1 probes for chromosomes 9q22 (FACC), 9p21(p16/CDKI2), and 17p13(p53). Ten of 14 hyperplasias (70%) showed deletions of chromosome 9. In 7 out of 8 patients with genetic alterations in the hyperplasias the genetic change was also present in the papillary tumor. Six out of 12 samples of microdissected normal urothelium also showed genetic alterations on chromosome 9. Microdissection of urothelial lesions, obtained during AFE, has led to the first unequivocal documentation of genetic changes in urothelial lesions diagnosed as normal in histopathology. Thus, this technical approach is important to provide insight into the earliest molecular alterations in bladder carcinogenesis.  (+info)

Retinitis pigmentosa and progressive sensorineural hearing loss caused by a C12258A mutation in the mitochondrial MTTS2 gene. (6/1281)

Family ZMK is a large Irish kindred that segregates progressive sensorineural hearing loss and retinitis pigmentosa. The symptoms in the family are almost identical to those observed in Usher syndrome type III. Unlike that in Usher syndrome type III, the inheritance pattern in this family is compatible with dominant, X-linked dominant, or maternal inheritance. Prior linkage studies had resulted in exclusion of most candidate loci and >90% of the genome. A tentative location for a causative nuclear gene had been established on 9q; however, it is notable that no markers were found at zero recombination with respect to the disease gene. The marked variability in symptoms, together with the observation of subclinical muscle abnormalities in a single muscle biopsy, stimulated sequencing of the entire mtDNA in affected and unaffected individuals. This revealed a number of previously reported polymorphisms and/or silent substitutions. However, a C-->A transversion at position 12258 in the gene encoding the second mitochondrial serine tRNA, MTTS2, was heteroplasmic and was found in family members only. This sequence change was not present in 270 normal individuals from the same ethnic background. The consensus C at this position is highly conserved and is present in species as divergent from Homo sapiens as vulture and platypus. The mutation probably disrupts the amino acid-acceptor stem of the tRNA molecule, affecting aminoacylation of the tRNA and thereby reducing the efficiency and accuracy of mitochondrial translation. In summary, the data presented provide substantial evidence that the C12258A mtDNA mutation is causative of the disease phenotype in family ZMK.  (+info)

Precise genetic mapping and haplotype analysis of the familial dysautonomia gene on human chromosome 9q31. (7/1281)

Familial dysautonomia (FD) is an autosomal recessive disorder characterized by developmental arrest in the sensory and autonomic nervous systems and by Ashkenazi Jewish ancestry. We previously had mapped the defective gene (DYS) to an 11-cM segment of chromosome 9q31-33, flanked by D9S53 and D9S105. By using 11 new polymorphic loci, we now have narrowed the location of DYS to <0.5 cM between the markers 43B1GAGT and 157A3. Two markers in this interval, 164D1 and D9S1677, show no recombination with the disease. Haplotype analysis confirmed this candidate region and revealed a major haplotype shared by 435 of 441 FD chromosomes, indicating a striking founder effect. Three other haplotypes, found on the remaining 6 FD chromosomes, might represent independent mutations. The frequency of the major FD haplotype in the Ashkenazim (5 in 324 control chromosomes) was consistent with the estimated DYS carrier frequency of 1 in 32, and none of the four haplotypes associated with FD was observed on 492 non-FD chromosomes from obligatory carriers. It is now possible to provide accurate genetic testing both for families with FD and for carriers, on the basis of close flanking markers and the capacity to identify >98% of FD chromosomes by their haplotype.  (+info)

Molecular cytogenetic detection of 9q34 breakpoints associated with nail patella syndrome. (8/1281)

The nail patella syndrome (NPS1) is an autosomal dominant disorder characterised by dysplasia of the finger nails and skeletal abnormalities. NPS1 has been mapped to 9q34, to a 1 cM interval between D9S315 and the adenylate kinase gene (AK1). We have mapped the breakpoints within the candidate NPS1 region in two unrelated patients with balanced translocations. One patient [46,XY,t(1;9)(q32.1;q34)] was detected during a systematic survey of old cytogenetic files in Denmark and southern Sweden. The other patient [46,XY,t(9;17)(q34.1;q25)] was reported previously. D9S315 and AK1 were used to isolate YACs, from which endclones were used to isolate PACs. Two overlapping PAC clones span the 9q34 breakpoints in both patients, suggesting that NPS1 is caused by haploinsufficiency due to truncation or otherwise inactivation of a gene at or in the vicinity of the breakpoints.  (+info)

Recent studies suggest that ANRIL expression mediates susceptibility to CAD1 via CDKN2B.2 We used fluorescently-labelled whole-blood RNA, from 20 healthy volunteers genotyped for the CAD-risk-SNP rs2891168, to probe custom-designed Agilent tiling expression microarrays. Raw data were normalized to probe GC content and housekeeping genes. We found that ANRIL exons 1-4 were more abundantly expressed in blood than 5-20, with exons 6, 8, 9, 20 showing low expression. We derived a set of training tiling probes from HUVEC cells in which ANRIL expression was attenuated using siRNA against exons 13 and 19. ANRIL expression (probes in exons 5,6,8,13,16,18,19) was reduced by at least 50% and CDKN2B expression (probes in exons 1,2) increased, with no effect on CDKN2A. We confirmed these data using real-time QPCR. Using the tiling probe training-set, a probe in exon 16 of ANRIL showed a CAD genotype-specific difference in expression (p,0.001), with the risk-allele lower, and probes in exon 2 of CDKN2B ...

This study suggests that GBM can be categorized into genetic subgroups and validates aCGH for detecting CNAs in GBM. Our data also identified candidate loci for homozygous deletions and amplifications. We compared aCGH results with data obtained by chromosomal CGH, FISH, and quantitative PCR, and conclude that RR obtained from aCGH is a reliable estimate of relative copy number. Moreover, unlike chromosome CGH, aCGH detects homozygous loss and amplicon size and maps CNAs to precise locations in the genome.. Genetic subgroups. Our data suggest that there are genetically distinct subgroups within GBM (Fig. 7). We identified three provisional genetic subgroups: one with loss of chromosome 10 and gain of chromosome 7 (group C), a second with loss of chromosome 10 only (group B); and a third without chromosome 10 loss or chromosome 7 gain (group A). If the mechanisms that underlie malignant behavior in these genetic subgroups substantially differ, we expect that subgroups may behave differently and ...
In countries where comparative genomic hybridization arrays (aCGH) and next generation sequencing are not widely available due to accessibility and economic constraints, conventional 400-500-band karyotyping is the first-line choice for the etiological diagnosis of patients with congenital malformations and intellectual disability. Conventional karyotype analysis can rule out chromosomal alterations greater than 10 Mb. However, some large structural abnormalities, such as derivative chromosomes, may go undetected when the analysis is performed at less than a 550-band resolution and the size and banding pattern of the interchanged segments are similar. Derivatives frequently originate from inter-chromosomal exchanges and sometimes are inherited from a parent who carries a reciprocal translocation. We present two cases with derivative chromosomes involving a 9.1 Mb 5p deletion/14.8 Mb 10p duplication in the first patient and a 19.9 Mb 5p deletion/ 18.5 Mb 9p duplication in the second patient.

Gorlin syndrome is a rare genetical disorder. It is caused as a result of mutation in the gene. The gene responsible for this mutation is present on the chromosome 9. The mutation changes the gene actual sequence thus making it abnormal. This results in gorlin syndrome.. The main factor that contributes to the gene mutation is climate change from cooler climates to intense hot climates. This sudden change makes the particular regions more prone to the syndrome. The races mostly affected by this syndrome are African Americans and Caucasians.. Gorlin syndrome is autosomal dominant and equally found among both men and women. Autosomal dominant means that one copy of the mutated gene is sufficient to cause the disease. The child inherits the syndrome if either parent is affected and passes the gene to the child. Symptoms of Gorlin Syndrome ...

Gorlin syndrome, also known as nevoid basal cell carcinoma syndrome, is a condition that affects many areas of the body and increases the risk of developing various cancerous and noncancerous tumors.In people with Gorlin syndrome, the type of cancer diagnosed most often is basal cell carcinoma, which is the most common form of skin cancer. Explore symptoms, inheritance, genetics of this condition.
The SUFU gene is associated with autosomal dominant nevoid basal cell carcinoma syndrome (NBCCS) (MedGen UID: 2554), and medulloblastoma (MedGen UID: 7517). Additionally, there is preliminary evidence supporting a correlation with susceptibility to meningioma (MedGen UID: 232281).
Hepatocellular carcinoma (HCC) is a common malignant tumor with high fatality rate. Recent studies reported that up-regulation of long non-coding RNA antisense non-coding RNA in the INK4 locus (lncRNA ANRIL) was found in HCC tissues, and which could affect HCC cells biological processes. However, the potential molecular mechanism of ANRIL in HCC is still unclear. The study aimed to uncover the effect of ANRIL on HepG2 cells growth, migration and invasion. The knockdown expression vectors of ANRIL were transfected into HepG2 cells, and qRT-PCR, CCK-8, flow cytometry, Transwell and western blot assays were performed to analyze the effect of ANRIL on cell proliferation, apoptosis, migration and invasion. The relative expression of miR-191 was then examined in ANRIL knockdown vector transfected cells. These experiments were repeated again for exploring the effect of miR-191 on HepG2 cells. NF-κB and Wnt/β-catenin signaling pathways were examined by using western blot assay. Knockdown of ANRIL inhibited
The HBL and LND1 cell lines, wt for BRAF, highly express PGC1alpha while hmel1, hmel9, hmel11, Mba72, M3, presenting BRAF mutations at the V600 residue, show a downregulation of this gene. MITF expression levels were more abundant in HBL and LND1 cell lines with respect to the other cell lines harbouring BRAF mutations. There is a direct correspondence between PGC1alpha and MITF levels: higher levels of PGC1alpha are associated with an enhanced MITF quantity. The analysis of cAMP levels in our melanoma cell lines showed a similar trend, being higher in wt BRAF cell lines compared to the other cell lines. ...
The nevoid basal cell carcinoma syndrome (NBCCS), or Gorlin syndrome, is a multisystem autosomal dominant disorder. The salient features of this syndrome include multiple basal cell carcinomas, palmar and/or plantar pits, odontogenic keratocysts, skeletal and developmental anomalies, and ectopic calcification. Other features include such tumors as ovarian fibromas and medulloblastomas. There is extensive interfamilial as well as intrafamilial variability with respect to the manifestation and severity of the phenotype. Alterations in the human homologue (PTCH) of the Drosophila segment polarity gene patched have been identified in NBCCS patients as well as tumors associated with this syndrome. We report several mutations in this gene in NBCCS patients and present the clinical phenotypes of the individuals in whom these mutations were identified.. ...

Normally, every cell has 2 copies of each gene: one inherited form the mother and one inherited from the father. NBCCS follows an autosomal dominant inheritance pattern, in which a mutation needs to happen in only 1 copy of the gene for a person to have the increased risk. This means that a parent with a gene mutation may pass along a copy of the normal gene or a copy of the gene with the mutation. Therefore, a child who has a parent with a mutation has a 50% chance of inheriting that mutation. A brother, sister, or parent of a person who has a mutation also has up to a 50% chance of having the same mutation. However, if the parents test negative for the mutation (meaning each persons test results found no mutation), the risk to the siblings significantly decreases but their risk may still be higher than an average risk. It is also possible that the NBCCS in an individual was caused not by an inherited mutation but, rather, by a spontaneous gene mutation (see below).. Options exist for people ...

This fusion gene is transcribed into a new 8.5-kilobase chimeric mRNA which is translated into a novel Mr 210,000 fusion protein which has a protein tyrosine kinase activity that is greatly increased in comparison to the activity of the normal abl protein. Studies from this laboratory and others have shown that virtually all patients with chronic myelogenous leukemia have this new bcr/abl fusion gene. In contrast to these findings in chronic myelogenous leukemia, a small number of patients with Ph1(+) acute lymphoblastic leukemia (ALL) have been studied and were found to lack the bcr/abl fusion gene [bcr(-)], but to have a new activation of abl, by recombination with an as yet undetermined region on chromosome 22. In this study, nine adults with Ph1(+)-ALL have been examined for evidence of a bcr/abl fusion gene. Of the nine ...

Introduction. Atrial fibrillation (AF) is a common arrhythmia in humans and a major cause of morbidity and mortality. We have previously reported a genome-wide study identifying sequence variants on chromosome 4q25 that confer risk of AF. We have now expanded our cohort for genome-wide association stud, in the attempt to discover additional variants that associate with the common forms of AF.. Methods. A sample set of 2,385 Icelandic patients with AF and/or atrial flutter (AFl) and 33,752 Icelandic population controls were genotyped with the Illumina HumanHap300 and HumanHapCNV370 bead chips, yielding 304,226 SNPs that were tested individually for association. Of the top ten SNPs, seven represented the previously discovered signal on chromosome 4q25. The remaining three SNPs were genotyped in three replication cohorts of European descent, from Iceland (989 cases and 2,027 controls), Norway (725 cases and 725 controls) and the United States (735 cases and 729 controls).. Results. One SNP, ...
