  1. 1. New roles for apical secretion and extracellular matrix assembly in Drosophila epithelial morphogenesis

    Författare :Satish Arcot Jayaram; Christos Samakovlis; Catherine Rabouille; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Utvecklingsbiologi; utvecklingsbiologi; Developmental Biology;

    Sammanfattning : Branched tubular organs, such as the lung and vascular system fulfill the respiratory needs of most animals. Optimal tissue function relies on the uniform sizes and shapes of the constituting branches in each organ. LÄS MER

  2. 2. Mating type switching and transcriptional silencing in Kluyveromyces lactis

    Författare :Emad Barsoum; Åström Stefan; Laura Rusche; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Mating type switch; transcriptional silencing; alpha3; transposase; Ume6; Mts1; Ras; cAMP; K. lactis; Developmental biology; Utvecklingsbiologi; utvecklingsbiologi; Developmental Biology;

    Sammanfattning : To explore the similarities and differences of regulatory circuits among budding yeasts, we characterized the role of unscheduled meiotic gene expression 6 (UME6) and a novel mating type switching pathway in Kluyveromyces lactis. We found that Ume6 was required for transcriptional silencing of the cryptic mating-type loci HMLα and HMRa. LÄS MER

  3. 3. Grainy head target genes in epithelial morphogenesis and wound healing

    Författare :Shenqiu Wang; Christos Samakovlis; Paul Martin; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; grh; targets; epidermal wound repair; tracheal tube size control; local immune responses; stit; verm; serp; PGRP-LC; CecA-LacZ; Developmental biology; Utvecklingsbiologi; utvecklingsbiologi; Developmental Biology;

    Sammanfattning : grainy head (grh) genes encode a family of transcription factors conserved from fly to human. Drosophila grh is the founding member of this gene family and has multiple functions, including tracheal tube size control, epidermal barrier formation and reconstruction after wounding. LÄS MER

  4. 4. A Comparative Study of Head Development in Mexican Axolotl and Australian Lungfish: Cell Migration, Cell Fate and Morphogenesis

    Författare :Rolf Ericsson; Rolf Ohlsson; Graham Budd; Lennart Olsson; Per Ahlberg; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Head development; axolotl; lungfish; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; Developmental Biology; miljömedicinsk utvecklingsbiologi;

    Sammanfattning : The development of the vertebrate head is a complex process involving interactions between a multitude of cell types and tissues. This thesis describes the development of the cranial neural crest and of the visceral arch muscles in the head of two species. LÄS MER

  5. 5. Epigenetic Regulation of the H19 Chromatin Insulator in Development and Disease

    Författare :Claes Holmgren; Rolf Ohlsson; Tomas Ekstöm; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; Developmental Biology; Miljömedicinsk utvecklingsbiologi;

    Sammanfattning : The coordinated regulation of gene expression must be tightly controlled for normal development to occur. In mammals, this issue is further complicated by the requirement of both the maternal and paternal genomes for normal development, reflecting the fact that a subset of genes are monoallelically expressed depending on parental inheritance, a phenomenon known as genomic imprinting.
