  2. 11. Spleno-pancreatic development assessed by 3D molecular imaging

    Author : Amir Asayesh; Ulf Ahlgren; Beatriz Sosa-Pineda; Umeå universitet; []
    Keywords : Cell biology; Spleen; Pancreas; Imaging; Development; Cellbiologi; miljömedicinsk utvecklingsbiologi; Developmental Biology;

    Abstract : The development of different organs and tissues along the gastrointestinal tract, including the pancreas, depends on signalling between the endoderm and the adjacent mesenchyme. The Nkx gene Bapx1 is involved in spatial control of organ-positioning in the spleno-pancreatic region, and deficiency in this gene results in unacceptable proximity of the splenic mesenchyme to the pancreas.

  4. 12. Characterization of Budding Yeast Nonhomologous End-Joining at DNA Double-Strand Breaks and Telomeres

    Author : Sidney Carter; Stefan Åström; Ed Louis; Stockholms universitet; []
    Keywords : DNA repair; nonhomologous end-joining; double-strand break; Developmental Biology; miljömedicinsk utvecklingsbiologi;

    Abstract : The yeast K. lactis efficiently integrates DNA by illegitimate recombination (IR). IR was completely dependent upon nonhomologous end-joining (NHEJ). In contrast to S. READ MORE

  5. 13. Molecular studies of intra-oocyte phosphatidylinositol 3 kinase (PI3K) signaling pathway in controlling female fertility

    Author : Pradeep Reddy Dubbaka Venu; Kui Liu; Evelyn Telfer; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Primordial follicles; Oocyte; PI3K; Biochemistry; Biokemi; Developmental Biology; miljömedicinsk utvecklingsbiologi;

    Abstract : The primordial follicle pool is the main source of developing follicles in the ovary. The length of reproductive life and the onset of menopause are governed by the amount of primordial follicles in the ovary. READ MORE

  6. 14. Dissecting sterol function during clathrin-dependent endocytosis and cytokinesis in Arabidopsis thaliana

    Author : Márcia Frescatada-Rosa; Markus Grebe; Wolfgang Lukowitz; Umeå universitet; []
    Keywords : Arabidopsis; membrane; sterols; cytokinesis; KNOLLE; endocytosis; clathrin; DRP1A; Developmental Biology; miljömedicinsk utvecklingsbiologi; molekylärbiologi; Molecular Biology; molecular cell biology; molekylär cellbiologi;

    Abstract : Sterols are lipid components of eukaryotic membranes. Alterations of membrane sterol composition perturb the execution of cell division, which in diverse eukaryotes can have severe consequences for development of the organism. Partitioning of the cytoplasm during cell division occurs at the final stage of cell division named cytokinesis. READ MORE

  7. 15. The functional roles of the intra-oocyte phosphatidylinositol 3-kinase (PI3K) signaling in controlling follicular development in mice

    Author : Krishna Rao Jagarlamudi; Kui Liu; Lena Sahlin; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; oocyte; PI3K signaling; primordial follicle; Obstetrics and gynaecology; Obstetrik och gynekologi; Developmental Biology; miljömedicinsk utvecklingsbiologi;

    Abstract : The key functions of the mammalian ovary are the production of fertilizable oocytes and thesecretion of steroid hormones. At the time of birth the human ovary is composed of basic unitstermed primordial follicles. Primordial follicles are long-lived structures in the ovary and some ofthem last until the woman reaches menopause. READ MORE
