11q23.1 and 11q25-qter YACs suppress tumour growth in vivo. (1/12529)

Frequent allelic deletion at chromosome 11q22-q23.1 has been described in breast cancer and a number of other malignancies, suggesting putative tumour suppressor gene(s) within the approximately 8 Mb deleted region. In addition, we recently described another locus, at the 11q25-qter region, frequently deleted in breast cancer, suggesting additional tumour suppressor gene(s) in this approximately 2 Mb deleted region. An 11q YAC contig was accessed and three YACs, one containing the candidate gene ATM at 11q23.1, and two contiguous YACs (overlapping for approximately 400-600 kb) overlying most of the 11q25 deleted region, were retrofitted with a G418 resistance marker and transfected into murine A9 fibrosarcoma cells. Selected A9 transfectant clones (and control untransfected and 'irrelevant' alphoid YAC transfectant A9 clones) were assayed for in vivo tumorigenicity in athymic female Balb c-nu/nu mice. All the 11q YAC transfectant clones demonstrated significant tumour suppression compared to the control untransfected and 'irrelevant' YAC transfected A9 cells. These results define two discrete tumour suppressor loci on chromosome 11q by functional complementation, one to a approximately 1.2 Mb region on 11q23.1 (containing the ATM locus) and another to a approximately 400-600 kb subterminal region on 11q25-qter.  (+info)

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. (2/12529)

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)

Multiple target sites of allelic imbalance on chromosome 17 in Barrett's oesophageal cancer. (3/12529)

Twelve Barrett's adenocarcinomas have been analysed for the occurrence of allelic imbalance (LOH) on chromosome 17 using 41 microsatellite markers. This study provides evidence for 13 minimal regions of LOH, six on 17p and seven on 17q. Four of these centre in the vicinity of the known tumour suppressor genes (TSGs) TP53 (17p13.1), NFI (17q11.2), BRCA1 (17q21.1), and a putative TSG (17p13.3). The tumours all displayed relatively small regions of LOH (1-10 cM), and in several tumours extensive regions of LOH were detected. One tumour displayed only two very small regions of LOH; 17p11.2 and 17p13.1. The frequency of allelic imbalance has been calculated based on the LOH encompassing only one minimal region, and based on all the LOH observations. By both evaluations the highest LOH frequencies were found for regions II (p53), III (17p13.1 centromeric to p53), IV (17p12), V (17p11.2) and VII (NF1, 17q11.2). Our data supports the existence of multiple TSGs on chromosome 17 and challenges the view that p53 is the sole target of LOH on 17p in Barrett's adenocarcinoma.  (+info)

Correlation between the status of the p53 gene and survival in patients with stage I non-small cell lung carcinoma. (4/12529)

The association of p53 abnormalities with the prognosis of patients with non-small cell lung carcinoma (NSCLC) has been extensively investigated to date, however, this association is still controversial. Therefore, we investigated the prognostic significance of p53 mutations through exons 2 to 11 and p53 protein expression in 103 cases of stage I NSCLC. p53 mutations were detected in 49 of 103 (48%) tumors. Two separate mutations were detected in four tumors giving a total of 53 unique mutations in 49 tumors. Ten (19%) of mutations occurred outside exons 5-8. Positive immunohistochemical staining of p53 protein was detected in 41 of 103 (40%) tumors. The concordance rate between mutations and protein overexpression was only 69%. p53 mutations, but not expression, were significantly associated with a shortened survival of patients (P<0.001). Furthermore, we investigated the correlation between the types of p53 mutations and prognosis. p53 missense mutations rather than null mutations were associated with poor prognosis (P < 0.001 in missense mutations and P=0.243 in null mutations). These results indicated that p53 mutations, in particular missense mutations, rather than p53 expression could be a useful molecular marker for the prognosis of patients with surgically resected stage I NSCLC.  (+info)

p73 at chromosome 1p36.3 is lost in advanced stage neuroblastoma but its mutation is infrequent. (5/12529)

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)

High polymorphism level of genomic sequences flanking insertion sites of human endogenous retroviral long terminal repeats. (6/12529)

The polymorphism at the multitude of loci adjacent to human endogenous retrovirus long terminal repeats (LTRs) was analyzed by a technique for whole genome differential display based on the PCR suppression effect that provides selective amplification and display of genomic sequences flanking interspersed repeated elements. This strategy is simple, target-specific, requires a small amount of DNA and provides reproducible and highly informative data. The average frequency of polymorphism observed in the vicinity of the LTR insertion sites was found to be about 12%. The high incidence of polymorphism within the LTR flanks together with the frequent location of LTRs near genes makes the LTR loci a useful source of polymorphic markers for gene mapping.  (+info)

Structure of cag pathogenicity island in Japanese Helicobacter pylori isolates. (7/12529)

BACKGROUND: cag pathogenicity island (PAI) is reported to be a major virulence factor of Helicobacter pylori. AIM: To characterise cagA and the cag PAI in Japanese H pylori strains. METHODS: H pylori isolates from Japanese patients were evaluated for CagA by immunoblot, for cagA transcription by northern blot, and for cagA and 13 other cag PAI genes by Southern blot. cagA negative strains from Western countries were also studied. Induction of interleukin-8 secretion from gastric epithelial cells was also investigated. RESULTS: All Japanese strains retained cagA. Fifty nine of 63 (94%) strains had all the cag PAI genes. In the remaining four, cag PAI was partially deleted, lacking cagA transcripts and not producing CagA protein. Details of the PAI of these strains were checked; three lacked cagB to cagQ (cagI) and continuously cagS to cag13 (cagII), and the remaining one lacked cagB to cag8. Western cagA negative strains completely lacked cag PAI including cagA. Nucleotide sequence analysis in one strain in which the cag PAI was partially deleted showed that the partial deletion contained 25 kb of cag PAI and the cagA promoter. Interleukin-8 induction was lower with the cag PAI partial deletion strains than with the intact ones. All Japanese cag PAI deleted strains were derived from patients with non-ulcer dyspepsia, whereas 41 of 59 (70%) CagA-producing strains were from patients with peptic ulcers or gastric cancer (p<0.05). CONCLUSIONS: Most Japanese H pylori strains had the intact cag PAI. However, some lacked most of the cag PAI in spite of the presence of cagA. Thus the presence of the cagA gene is not an invariable marker of cag PAI related virulence in Japanese strains.  (+info)

Screening for mutations of the cationic trypsinogen gene: are they of relevance in chronic alcoholic pancreatitis? (8/12529)

BACKGROUND: In hereditary pancreatitis mutations of exons 2 (N21I) and 3 (R117H) of the cationic trypsinogen gene have been described. AIMS: To investigate whether the same mutations can also be found in patients with chronic alcoholic pancreatitis. METHODS: Leucocyte DNA was prepared from 23 patients with chronic alcoholic pancreatitis, 21 with alcoholic liver cirrhosis, 34 individuals from seven independent families with hereditary pancreatitis, and 15 healthy controls. DNA was also obtained from pancreatic tissue (n=7) and from pancreatic juice (n=5) of patients suffering from chronic alcoholic pancreatitis. R117H was detected by restriction digestion with Afl III. N21I was identified by an allele specific polymerase chain reaction (PCR). RESULTS: R117H was detected in four families with hereditary pancreatitis. The N21I mutation was identified in three families. All mutations were confirmed by sequencing of the corresponding DNAs. In patients with chronic alcoholic pancreatitis neither the exon 2 nor exon 3 mutations were present in blood leucocytes, pancreatic juice, or pancreatic tissue. DNA of the patients with alcoholic liver cirrhosis as well as all controls was of wild type. CONCLUSIONS: The allele specific PCR may be used to screen for the N21I mutation of cationic trypsinogen. Both trypsinogen mutations were found in hereditary pancreatitis but do not seem to be major pathogenic factors in chronic alcoholic pancreatitis.  (+info)

Simple Sequence Length Polymorphisms (SSLPs) are used as genetic markers with polymerase chain reaction (PCR). An SSLP is a type of polymorphism: a difference in DNA sequence amongst individuals. SSLPs are repeated sequences over varying base lengths in intergenic regions of deoxyribonucleic acid (DNA). Variance in the length of SSLPs can be used to understand genetic variation between two individuals in a certain species. An example of the usage of SSLPs (microsatellites) is seen in a study by Rosenberg et al., where SSLPs were used to cluster different continental races. The study was critical to Nicholas Wades New York Times Bestseller, Before the Dawn: Recovering the Lost History of Our Ancestors. Rosenberg studied 377 SSLPs in 1000 people in 52 different regions of the world. By using PCR and cluster analysis, Rosenberg was able to group individuals that had the same SSLPs . These SSLPs were extremely useful to the experiment because they do not affect the phenotypes of the individuals, ...
A population size of 100 was simulated for 10 biallelic or multiallelic marker loci for 100 generations before pedigree recording. In each generation, the number of male and female parents was 50 and their alleles were transmitted to descendants on the basis of Mendelian segregation using the gene-dropping method (MacCluer et al. 1986). Parents were randomly mated with a total of two offspring for each of 50 mating pairs. In the multiallelic marker model (e.g., microsatellites), the number of alleles assumed in each marker locus was 4 and base allele frequencies were all at 0.25. In the biallelic marker model (e.g., SNP), the number of alleles was 2 and starting allele frequencies were 0.5. The marker alleles were mutated at rates of 4 × 10−4 per generation in multiallelic markers (Dallas 1992; Weber and Wong 1993; Ellegren 1995) and 2.5 × 10−8 per generation in biallelic markers (Nachman and Crowell 2000). A mutated locus was switched between the two existing alleles for biallelic markers ...

The HCP5 genetic marker was not a good predictor of quitting abacavir, perhaps because the study considered stopping abacavir for any reason, not just the hypersensitivity reaction, and because people in Switzerland started getting HLA-B*5701 screening before beginning abacavir during this period. For the other four drugs, hazard ratios adjusted for other risk factors found that genetic markers independently predicted stopping efavirenz (adjusted hazard ratio [aHR] 3.10, 95% confidence interval [CI] 1.48 to 6.46, P = 2.59 x 10(-3) and atazanavir (aHR 7.31, 95% CI 2.86 to 18.72, P = 3.30 x 10(-6)). There was a strong trend toward an independent effect of genetic markers on quitting tenofovir (aHR 2.30, 95% CI 0.99 to 5.31, P = 0.052) but not lopinavir (aHR 1.42, 95% CI 0.62 to 3.25, P = 0.41 ...

Testing genetic markers for Hardy-Weinberg equilibrium is an important issue in genetic association studies. The HardyWeinberg package o ers the classical tests for equilibrium, functions for power computation and for the simulation of marker data under equilibrium and disequilibrium. Functions for testing equilibrium in the presence of missing data by using multiple imputation are provided. The package also supplies various graphical tools such as ternary plots with acceptance regions, log-ratio plots and Q-Q plots for exploring the equilibrium status of a large set of diallelic markers. Classical tests for equilibrium and graphical representations for diallelic marker data are reviewed. Several data sets illustrate the use of the package ...
Our research will identify and develop a new type of polymorphic DNA marker that will allowsimplification and acceleration of genetic analyses. These multiplex-compatible amplifiable markers willhave the advantage of simplified analysis versus current PCR-based marker systems, allowing detectionin a new agarose gel format rather than requiring denaturing polyacrylamide gels. The markers will alsobe amenable to fluorescent analysis rather than requiring radioactive detection. In phase l, the plan isto describe a method to identify large-numbers of the new markers and to isolate and characterizeseveral examples. In addition, the basic expectations that they will produce precise amplificationproducts and that their allelic content can be determined more efficiently, safely, and cheaply than othersystems will be demonstrated. This will establish the superiority of this marker class and support thework of phase Il which includes isolation of a large number of the markers, more thorough ...

A fragment of genetic material associated with a certain location in the genome is known as molecular marker. Molecular markers have been useful in determining hybrid purity, identifying genotypes, discovering genes linked to known markers and also enable an in-depth analysis of quantitative traits, allowing interesting alleles to be found in wild or cultivated germplasm. Due to its heritability and relatively easy to assay, made DNA based markers more advantageous than the other markers. The predominate sequence based markers like Single Nucleotide Polymorphisms (SNPs), Simple Sequence Repeats (SSRs) and high throughput DArT assays are widely used in the genetic analysis..

I cant believe the hatchet job mainstream reporting does on the effectiveness and safety of nutritional supplements. The idea of health and illness is very complicated, which these reports seldom acknowledge. Just like prescribed drugs, not everything is going to work for every person. If fact, the newest research is on genetic markers showing whether or not new drugs will work on the individual person. Medicine knows there are many cofactors that go hand in hand with any illness as well as usefulness of medications. Id add supplements to the list.. As for genetics, something has to flip the genetic switch for illness to happen. The thing that flips or stops the switch is called a cofactor. As for the role of the dice, chance does come into play, but cofactors are a big player as well. Here are some examples according to Julian Whittaker, MD. He says in his newsletter that if everyone 65 and older took calcium and vitamin D, about 776,000 hospitalizations for hip fractures could be avoided. He ...

Only ~50% of the SNPs detected using raw data coincide between SMA and Blossoc methods. This percentage increased to 67% when using corrected data. The disagreement between the corrected methods was due to 4 SNPs: SNP 331 was detected with SMA (QxPak). This SNP showed high LD with SNP 402 (D ≈ 1, r2 = 0.3), which was highly associated with the phenotype. The equivalent SNP in the SMA raw (323) showed low BPP (0.1). Therefore, SNP 331 is probably a false positive. SNP 3952 was detected with Blossoc and also with SMA raw (BPP = 0.99), suggesting that it is a true QTL. The SNP identified in the beginning of Chromosome 3 (2133) by the SMA method (BPP = 0.89) was also detected with Blossoc on raw data, but was not selected with Blossoc on corrected data. This SNP showed a well defined peak with corrected Blossoc, close to the significance threshold (HQ = 13). Therefore, SNP 2133 is probably also a true QTL. These results indicate that the thresholds defined here for both SMA and Blossoc on ...
This article takes a quantitative approach to the grammar of English two-part discourse marker sequences like oh well, you know I mean, etc. We investigate the internal ordering preferences of such sequences in spoken American English corpus data from the perspective of grammaticalization. From this perspective, the development of many discourse markers can be understood as involving a process of increasing syntactic de-categorialization (Hopper 1991) as the grammaticalizing element loses its original grammatical constraints and comes to function as a marker at the level of discourse. We test the hypothesis that discourse marker grammaticalization results in largely unconstrained ordering possibilities. Our analysis shows that, on the contrary, discourse marker sequencing is highly constrained. We interpret these constraints in terms of Auers (1996) model of discourse marker grammaticalization. Discourse marker sequencing is characterized by strong persistence of a markers original syntactic category
The study, published in the February issue of the American Journal of Human Genetics, involved 3,636 people enrolled in a large trial on the genetics of hypertension. To see whether genetic markers correspond to the standard racial categories, the scientists first analyzed the volunteers DNA, identifying which genetic markers they carried. They then used a computer program to cluster people based on genetic similarities; those who shared genetic markers were grouped together. Finally, the scientists compared those groupings with the volunteers self-identified race. The result: people who considered themselves white had been grouped by the computer, based on their genetic markers, in one cluster, while people who consider themselves African-American had been grouped in a second, different cluster ...

As mentioned elsewhere in this document, in the clinical research process and assistance it will be essential the use of genetic biomarkers, this will allow to generate drugs for groups of patients (stratification) or in some cases individualization. For the current Clinical Test concept, knowledge of the genetic profile can help to avoid interactions with other drugs. From the assistance point of view it is essential to generate an assistance model that stratifies / personalizes the prescription. Among the genetic markers, those that determine the metabolic capacity are the most studied and those most included in the regulation framework. However, one of the great problems is the extrapolation of the phenotype data from the genotype, therefore, it is necessary to generate a new algorithm that allows qualitative information to be transformed into quantitative information, something that can be done from the existing data in the literature and that generated within the project. The possibility of ...

Sclerostin is a potent inhibitor of Wnt signaling and bone formation. However, there is currently no information on the relation of circulating sclerostin levels to age, gender, or bone mass in humans. Thus we measured serum sclerostin levels in a population-based sample of 362 women [123 premenopausal, 152 postmenopausal not on estrogen treatment (ET), and 87 postmenopausal on ET] and 318 men, aged 21 to 97 years. Sclerostin levels (mean ± SEM) were significantly higher in men than women (33.3 ± 1.0 pmol/L versus 23.7 ± 0.6 pmol/L, p , .001). In pre- and postmenopausal women not on ET combined (n = 275) as well as in men, sclerostin levels were positively associated with age (r = 0.52 and r = 0.64, respectively, p , .001 for both). Over life, serum sclerostin levels increased by 2.4- and 4.6-fold in the women and men, respectively. Moreover, for a given total-body bone mineral content, elderly subjects (age ≥ 60 years) had higher serum sclerostin levels than younger subjects (ages 20 to 39 ...
Several molecular marker systems have been developed for assessing genetic diversity in crop germplasm collections. A trade-off often exists between the number of loci that can feasibly be sampled by a marker system and the amount of information provided by each locus. We compared the usefulness of two marker systems for revealing genetic diversity and population structure in cassava (Manihot esculenta Crantz): simple sequence repeats (SSRs) and diversity array technology (DArT) markers. DArTs survey many more loci per reaction than do SSRs; however, as bi-allelic, dominant markers, DArTs provide less polymorphism information per locus. Genetic differentiation was assessed in a randomly selected set of 436 cassava accessions, consisting of 155 African and 281 Latin American accessions. A genome-wide set of 36 SSR markers and a DArT array of approximately 1000 polymorphic clones were used to assess genetic diversity and differentiation. Cluster analyses were performed using principal coordinate ...
Background Genetic markers and linkage mapping are basic prerequisites for marker-assisted selection and map-based cloning. In the case of the key grassland species Lolium spp., numerous mapping populations have been developed and characterised for various traits. Although some genetic linkage maps of these populations have been aligned with each other using publicly available DNA markers, the number of common markers among genetic maps is still low, limiting the ability to compare candidate gene and QTL locations across germplasm. Results A set of 204 expressed sequence tag (EST)-derived simple sequence repeat (SSR) markers has been assigned to map positions using eight different ryegrass mapping populations. Marker properties of a subset of 64 EST-SSRs were assessed in six to eight individuals of each mapping population and revealed 83% of the markers to be polymorphic in at least one population and an average number of alleles of 4.88. EST-SSR markers polymorphic in multiple populations ...
Scientists from an international consortium have identified a large number of new genetic markers that predispose individuals to lupus.
To increase the utility of the previously constructed physical map of the chromosome of Neisseria gonorrhoeae FA1090, 28 additional genetic markers were localized on the map. Cloned gonococcal genes were used to probe Southern blots of restriction enzyme-digested DNA separated on pulsed-field gels, thus identifying the fragment in each of several digests to which the probe hybridized and the map location of each gene. The addition of the new markers brings the total number of mapped loci for this strain to 68; the locations of all of those markers on the updated map are shown. ...
A genetic marker is a gene or DNA sequence with a known location on a chromosome that can be used to identify individuals or species. It can be described as a variation (which may arise due to mutation or alteration in the genomic loci) that can be observed. A genetic marker may be a short DNA sequence, such as a sequence surrounding a single base-pair change (single nucleotide polymorphism, SNP), or a long one, like minisatellites. For many years, gene mapping was limited to identifying organisms by traditional phenotype markers. This included genes that encoded easily observable characteristics such as blood types or seed shapes. The insufficient number of these types of characteristics in several organisms limited the mapping efforts that could be done. This prompted the development of gene markers which could identify genetic characteristics that are not readily observable in organisms (such as protein variation). Some commonly used types of genetic markers are: RFLP (or Restriction fragment ...
The development of array-based high-throughput genotyping methods created significant opportunities to increase the number of genetic populations for linkage analysis. In the present study, a strategy was proposed for mapping QTLs (quantitative trait loci) based on DArT (diversity arrays technology) genotyping system. A consensus linkage map was constructed with both DArT and SSR markers by utilizing a subgroup DH population, and a second linkage map was constructed with SSR markers alone and a more extensive full DH population. Resistance to barley net-type net blotch disease was analyzed using the subpopulation data with the high-density consensus linkage map and the full-population data with the low-density SSR linkage map, respectively. Two interactive QTLs were detected either by the sub- or full population. Simulation studies were conducted to validate the strategy presented in this chapter. In addition, a computer program written in C++ is freely available on the web to deal with the data ...
Introduction. Genetic linkage maps have been obtained for several plant species and are the basis for advanced genetic studies that provide a better understanding of the inheritance, identification and isolation of genes (Roose et al., 2000). Cloning and gene insertion through genetic transformation have been widely used in species with well-defined genetic maps (Gmitter Jr. et al., 1996).. Different types of molecular markers have been used to obtain genetic linkage maps. Molecular markers are used because they are highly polymorphic and are not influenced by the environment. Among these, random amplified polymorphic DNA (RAPD) markers are the most common because the technique is easy, inexpensive, uses a low amount of genomic DNA, and produces markers that are highly polymorphic and that represent the whole genome (Ferreira and Grattapaglia, 1998). RAPD markers are detected by the random amplification of genomic DNA fragments of different sizes through the polymerase chain reaction (PCR) ...
Simple sequence repeats (SSRs) or microsatellites were tandemly arranged repeats of short DNA motifs (1-6 nucleotides long), which extensively distributed in eukaryotes including the plants, animals and microorganisms, as well as in some prokaryotes [1]. SSRs were commonly regarded as genomic junk with no significant role as genomic information in a long time until the more utilizing of SSR repeat-number variation and accumulating evidence to support the hypothesis that SSRs could play a positive role in adaptive evolution [2-4]. For assaying genetic variation, SSRs markers based on the repeat number variation were showing significant advantages over the variety of other molecular markers, including restriction fragment length polymorphisms (RFLPs), random amplification of polymorphic DNA (RAPD), and amplified fragment length polymorphisms (AFLPs) [5-7]. As a codominant marker, SSRs have proven to be highly polymorphic, easily reproducible, low costing, facility amplified, and not specifically ...
To facilitate mapping of the cystic fibrosis locus (CF) and to isolate the corresponding gene, we have screened a flow-sorted chromosome 7-specific library for additional DNA markers in the 7q31-q32 region. Unique (single-copy) DNA segments were selected from the library and used in hybridization analysis with a panel of somatic cell hybrids containing various portions of human chromosome 7 and patient cell lines with deletion of this chromosome. A total of 258 chromosome 7-specific single-copy DNA segments were identified, and most of them localized to subregions. Fifty three of these corresponded to DNA sequences in the 7q31-q32 region. Family and physical mapping studies showed that two of the DNA markers, D7S122 and D7S340, are in close linkage with CF. The data also showed that D7S122 and D7S340 map between MET and D7S8, the two genetic markers known to be on opposite sides of CF. The study thus reaffirms the general strategy in approaching a disease locus on the basis of chromosome ...
We present a genetic map for Xenopus tropicalis, consisting of 2886 Simple Sequence Length Polymorphism (SSLP) markers. Using a bioinformatics-based strategy, we identified unique SSLPs within the X. tropicalis genome. Scaffolds from X. tropicalis genome assembly 2.0 (JGI) were scanned for Simple Sequence Repeats (SSRs); unique SSRs were then tested for amplification and polymorphisms using DNA from inbred Nigerian and Ivory Coast individuals. Thus identified, the SSLPs were genotyped against a mapping cross panel of DNA samples from 190 F2 individuals. Nearly 4000 SSLPs were genotyped, yielding a 2886-marker genetic map consisting of 10 major linkage groups between 73 and 132cM in length, and 4 smaller linkage groups between 7 and 40cM. The total effective size of the map is 1658cM, and the average intermarker distance for each linkage group ranged from 0.27 to 0.75cM. Fluorescence In Situ Hybridization (FISH) was carried out using probes for genes located on mapped scaffolds to assign linkage ...
The field of molecular phylogenetics has benefited greatly from the recent advances of modern sequencing approaches that allow for the generation of large genomics data sets Nonetheless a lack of suitable genetic markers and incomplete taxon sampling remain common problems in studies of evolutionary relatedness. Most phylogenetic studies are based on mitochondrial DNA (mtDNA) because information about the nuclear genome and strategies to develop new genetic markers are often not available. The use of appropriate genetic markers and the inclusion of both a geographically and phylogenetically comprehensive taxon sampling are required for adequately reconstructing evolutionary histories among different taxa. This is particularly true for studies of recent diversification. Mayflies (Ephemeroptera) are ancient freshwater insects, dating back more than 300 million years, but at the same time have been reported to successfully colonize and diversify on recently formed Atlantic oceanic islands. This combination
Development of DNA markers in forest genetics has overcome the limitations on the number of the used to date morphological and biochemical markers and provided the tools that study variation in coding, non-coding and highly variable regions of both nuclear and organelle (chloroplast and mitochondrial) genomes. In phylogeografic and phylogenetic studies of tree populations as well as gene flow, organelle genomes and highly variable genetic markers proved to be highly informative. Many genetic markers belong to so-called anonymous DNA marker type. Techniques based on these markers are: microsatellites or simple sequence repeats (SSRs), restriction fragment length polymorphisms (RFLPs), random amplified polymorphic DNA (RAPDs), and amplified fragment length polymorphisms (AFLPs). These marker types generally measure neutral DNA variation. They proved to be very useful (with different efficiency) in the analyses of phylogenetic relationships, population structure, mating system, gene flow, parental ...

After testing several genome complexity reduction methods we identified the PstI/TaqI method as the most effective for Eucalyptus and developed 18 genomic libraries from PstI/TaqI representations of 64 different Eucalyptus species. A total of 23,808 cloned DNA fragments were screened and 13,300 (56%) were found to be polymorphic among 284 individuals. After a redundancy analysis, 6,528 markers were selected for the operational array and these were supplemented with 1,152 additional clones taken from a library made from the E. grandis tree whose genome has been sequenced. Performance validation for diversity studies revealed 4,752 polymorphic markers among 174 individuals. Additionally, 5,013 markers showed segregation when screened using six inter-specific mapping pedigrees, with an average of 2,211 polymorphic markers per pedigree and a minimum of 859 polymorphic markers that were shared between any two pedigrees ...

After accounting for the larger physical size of the RGSC 6.0/rn6 rat genome build (2,619 Mb) compared with the original Baylor 3.4/rn4 rate genome build (2,554 Mb), the increased size of the rat genetic map (1,708 cM) is proportional to the original Jensen-Seaman map (1,542 cM). Thus, although the coordinates of highly recombinant regions in the rat genome were refined in the revised rat genetic map, the sex-averaged genomewide recombination rates did not change (0.66 cM/Mb vs. 0.65 cM/Mb). Although the genomewide recombination rates did not change, fine-scale localization of highly recombinant regions differed between the Jensen-Seaman map and the revised rat genetic map. One potential reason for the refined localization of highly recombinant regions in the revised rat genetic map is the greater potential of genetic variation due to the possibility of eight informative HS founder haplotypes per genomic position, whereas prior rat genetic maps relied on crosses between two parental strains with ...
We report the establishment of a hybridization-based marker system for the rat genome based on the PCR amplification of interspersed repetitive sequences (IRS). Overall, 351 IRS markers were mapped within the rat genome. The IRS marker panel consists of 210 nonpolymorphic and 141 polymorphic markers that were screened for presence/absence polymorphism patterns in 38 different rat strains and substrains that are commonly used in biomedical research. The IRS marker panel was demonstrated to be useful for rapid genome screening in experimental rat crosses and high-throughput characterization of large-insert genomic library clones. Information on corresponding YAC clones is made available for this IRS marker set distributed over the whole rat genome. The two existing rat radiation hybrid maps were integrated by placing the IRS markers in both maps. The genetic and physical mapping data presented provide substantial information for ongoing positional cloning projects in the rat. (C) 2000 Academic ...

Purpose: BHLHB4 is a transcription factor essential to the maturation of rod bipolar cells (RBs). Adult Bhlhb4-/- mice lack RBs; whilst born in normal numbers, RBs die from postnatal day 8 (PN8) in Bhlhb4-/- retina, suggesting BHLHB4 is required for RB survival. Here we compare the transcriptomes of developing and adult Bhlhb4-/- retina to wildtype (WT) in order to identify novel genetic markers of RBs that may also be important for RB development and/or function.. Methods: Bhlhb4-/- and WT retinal transcriptomes were compared using gene expression microarrays in adult mice (Affymetrix, n=4) and by RNAseq in PN7 mice (n=6): a time that immediately predates significant differences in RB numbers between Bhlhb4-/- and WT retina. Candidate genes were investigated for co-expression with known RB-specific markers in mature RBs using immunofluorescence (IF) and evaluated for differential expression in developing Bhlhb4-/- RBs compared to WT at PN7 with rtPCR and IF.. Results: In adult mice, 97 genes ...

Interpretive Summary: Microsatellite markers form the scaffolding for the construction of the bovine genetic maps and the mapping of genes influencing economically important traits. They have been used to study the divergence, evolution, and domestication of the bovids and genetic differences across and within breeds. Two bloodlines of Romosinuano cattle exist in the U.S.A. today; one from Costa Rica developed by upgrading (COR) and the other, purebred, from Colombia (COL). Because the bloodlines cannot be distinguished by physical appearance, we attempted to find out if genetic markers could be used to: (1) determine the genetic variation between the two bloodlines and (2) whether an individuals bloodline of origin could be determined based on genetic markers. The discernment of bloodline of origin for individual animals has not yet been accomplished in beef cattle. Using 50 public microsatellite markers, we found that allele frequencies among the shared alleles and alleles unique to either ...

VANCOUVER, B.C. AND LOS ANGELES - An upcoming feature-length documentary, Mixed Match, explores the unique challenges faced by multiethnic patients with deadly blood diseases when searching for bone marrow donors.. Mixed Match, inspired by the work of L.A.-based outreach group Mixed Marrow, explains how race and ethnicity play a critical role in finding a marrow match for patients suffering from fatal blood diseases.. In order for a marrow or stem cell match to occur between a patient and donor, genetic markers on the cells must align. Because many of these markers are specific to certain ethnic groups, multiracial people often carry markers in uncommon combinations.. To put this in perspective, if a patient diagnosed with leukemia has a mixed Egyptian, Japanese and Russian background, chances are high that only a person with a similar ethnic blend could be a possible donor. For mixed patients, mono-racial parents and relatives will not likely be a genetic match-even siblings hold only a 1 ...
Unique Jan Brouwer Genetic Marker Found: Results from extending the Y-DNA test to 67 markers in some members of the Jan Brouwer descendants has revealed that we have a marker value that is so rare that it is specific to identifying our own family branch within the larger haplogroup I2b1c. A very rare DYS565 Allele value of 7 repeats has been found in the Jan Brouwer descendants. This value defines a unique family branch within the major haplogroup I2b1c; a mutation that likely occurred in an ancestor living in the Belgium / Netherlands / Germany region 400 to 700 years before the present. If two people share the allele value on this marker and are similar enough across the rest of the markers to share a common ancestor in a genealogical time frame, then they belong to the same family branch and everyone without the rare allele does not. - Richard Brewer. ...

Molecular phylogenetic is the branch of phylogeny that analyzes hereditary molecular diversity, mainly in DNA sequences, to increase data on an organisms evolutionary relationships. Due to the taxonomic levels of the study, various molecular markers are applied in molecular phylogeny. The selection of molecular instrument is of paramount matter to ensure that a proper level of variation is meliorated to respond the phylogenetic question. In this review, we have been trying to discuss about gene markers used in the plant phylogeny at various taxonomic levels. The current gene markers used in phylogeny include: the ribosomal nuclear genes, low copy nuclear genes and the extra-nuclear genome (mitochondrial and chloroplastic genomes). Conserved regions could be used at higher taxonomic levels in phylogenetics studies and regions with more changes could be applied between closely related taxa. One of the most common sequences for studying the phylogenetic relationships at the generic and infrageneric

While most fans would think that the story of House Frey would be over following the vengeance Arya wrought upon them at the end of Season 6/ the beginning of Season 7 for what they did to her own family at the Red Wedding, apparently there is just a little more story to come from the infamous House before Game of Thrones is over.. According to fan-site The Watchers on the Wall, an actress named Danielle Galligan has been cast as a character named Sarra, who fans of George R.R. Martins source books will recall is the name of Walder Freys granddaughter (her name is even dropped in Season 3 of the series as a potential bride for Robb Stark when Walder is trying to get the King of the North to marry into his family). Of course, there is a chance that this Sarra is not the Sarra who is Walder Freys granddaughter, but that would be odd for Thrones to use the name and spelling of a character already mentioned on the show for a brand new character.. So if she is a Frey, does this mean more ...

  • They occur in less than 1 per cent of women, Simard says, whereas some of the newly identified genetic markers are much more common. (theglobeandmail.com)
  • however, their concentrations are not necessarily amenable to source apportionment because the markers may differ in prevalence across sources. (epa.gov)
  • This discovery could potentially lead to an early genetic test, which could help reveal those who are most at risk for Alzheimer's - leading to earlier, more effective treatments. (foxnews.com)
  • Much of the genetic research on Alzheimer's centers on amyloid-beta, a key component of brain plaques that build up in the brains of people with the disease. (healthcanal.com)
  • Even so, the results were promising because they showed that if you don't have the genetic marker for Alzheimer's disease, you stand a very good chance of avoiding it altogether by use of the supplement. (inquisitr.com)
  • According to the Forbes report, "it's still possible that starting fish oil supplementation during or before middle age could protect against developing Alzheimer's even for people with the genetic marker. (inquisitr.com)
  • Blood group A phenotype and homozygous plasma haptoglobin (2-2) were found associated with CL(P). The findings suggest that the individuals possessing these markers are more likely to develop congenital CL(P). (biomedsearch.com)
  • Thus, well-designed, multi-disciplinary investigations of genetic, immune and microbial etiologies of HAEC, with sufficient power to detect differences in disease phenotype are critically needed. (centerwatch.com)
