  1. 21. Investigations of Leucine-rich repeats and immunoglobulin-like domain-proteins 1 and 2 (LRIG1 and LRIG2) and their genes in cancer

    Författare :Mahmood Faraz; Håkan Hedman; Roger Henriksson; Rolf Bjerkvig; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; LRIG1; LRIG2; PDGFR; glioma; interactome; breast cancer; prognosis; Oncology; onkologi;

    Sammanfattning : The mammalian leucine-rich repeats and immunoglobulin-like domains (LRIG) gene family consists of three different members, LRIG1, LRIG2, and LRIG3. These genes are expressed in all human and mouse tissues analyzed to date. LÄS MER

  3. 22. Characterization of human chromosome 22 : cloning of breakpoints of the constitutional translocation t(11;22)(q23;q11) and detection of small constitutional delections by microarray CGH

    Författare :Isabel Tapia Paez; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Chromosome 22; t 11; 22 q23; q 11 ; inverted repeats palindromes; DiGeorge Velo-cardio-facial syndrome; array-CGH;

    Sammanfattning : Chromosome 22 is the second smallest human chromosome, composing approximately 1.5% of the genome. The short arm of this acrocentric chromosome harbors ribosomal genes and the long arm contains the protein coding genes. LÄS MER

  4. 23. Functional analysis of genetic variants in putative low penetrate breast cancer genes

    Författare :Haixin Lei; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Breast cancer; low penetrance gene; CDH1; ILC; IDC; mutation; SNP; BA CHI; ATM; EST1; cryptic splice site; SR proteins; dinucleotide repeats; splicing silencer.;

    Sammanfattning : Paper I & II: CDH1 germline mutations predispose individuals to diffuse gastric cancer, but its role in breast cancer is less clear. Somatic CDH1 mutations were reported to be frequent in lobular tumours (ILC), but they have not been found in ductal carcinomas (IDC). LÄS MER

  5. 24. Repetitive DNA in search of a function - a study of telomeric and centromeric sequences in Chironomus

    Författare :Casimiro Castillejo-Lopez; Udo Häckers grupp Utvecklingsbiologi i invertebrater; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chironomus; CENP-B box; mobile elements; reverse transcriptase; gene conversion; satellite; repetitive DNA; Telomere; centromere; Genetics; cytogenetics; Genetik; cytogenetik;

    Sammanfattning : Repetitive DNA is quantitatively the main component of telomeres and centromeres, structures responsible for maintenance of the eukaryotic chromosome. The telomere is the specialized nucleoprotein complex that terminates linear chromosomes. LÄS MER

  7. 25. Organization of centromere associated DNA in Chironomus pallidivittatus

    Författare :Hong He; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Genetics; Chironomus.; pericentric DNA; repetitive DNA; centromere; transposable element; cytogenetics; Genetik; cytogenetik;

    Sammanfattning : Centromeres have not yet been functionally defined in higher eu- karyotes, largely due to the huge amounts of repeated DNA in these regions of most species and difficulties of delimiting centromeric from pericentric regions. Also the latter have large quantities of mostly noncoding DNA, expressed cytologically as pericentric heterochromatin. LÄS MER
