    Sammanfattning : The common shrew, Sorex araneus, has one of the most variable karyotypes among mammals, displaying numerous chromosomes races throughout its distribution, which can be categorized into different karyotypic groups. The objective of this thesis was to examine the postglacial population history of Fennoscandian common shrews using autosomal microsatellites, mitochondrial DNA (mtDNA) and a Y chromosome specific microsatellite (L8Y).

    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Klinisk genetik; Clinical genetics; RBP56; APRIL; TFG; FUS; EWS; EST database; fusion genes; chromosome; molecular genetics; cancer; Cytology; oncology; cancerology; Cytologi; onkologi;

    Sammanfattning : Using computer-assisted sequence homology searches we identified three genes encoding proteins similar to certain fusion partner proteins in cancer. The novel APRIL gene was localized to 15q25 and encodes a protein, containing an acidic amino-acid region similar to that/those of leukemia-associated fusion partner proteins DEK and SET. LÄS MER

  4. 3. Genetic characterisation of novel resistance alleles to stem rust and stripe rust in wheat-alien introgression lines

    Sammanfattning : Bread wheat (Triticum aestivum L., 2n = 6x = 42, AABBDD) is one of the most important food crops world-wide, but is attacked by many diseases and pests that cause significant yield losses. Globally, stem rust (Sr) (Puccinia graminis f. sp. LÄS MER

  5. 4. Setosphaeria turcica, fungal mating and plant defence

    Författare :Thomas Martin; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The heterothallic ascomycete Setosphaeria turcica (anamorph: Exserohlium turcicum) causes turcicum leaf blight on maize and sorghum. A survey was undertaken in Uganda to examine the sorghum – S. turcica interaction in terms of disease severity and incidence, overall fungal population structure, and new resistant resources.

  7. 5. The role of PDGFB in dermatofibrosarcoma protuberans and giant cell fibroblastoma

    Författare :Kevin P O'Brien; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Dermatofibrosarcoma protuberans; giant cell fibroblastoma; translocation; FISH; translocation breakpoint; fusion gene; oncogene; Platelet derived growth factor B-chain; collagen type I alpha 1; tumor formation; autocrine stimulation;

    Sammanfattning : Dermatofibrosarcoma protuberans (DFSP) and giant cell fibroblastoma (GCF) are rare invasive tumors of the dermis. GCF is considered the juvenile form of DFSP. Both DFSP and GCF are characterized by the presence of chromosomal aberrations involving chromosomes 17 and 22. LÄS MER
