  2. 16. Molecular Mechanisms Underlying Abnormal Placentation in the Mouse

    Author : Yang Yu; Reinald H. Fundele; Rolf Ohlsson; J. GRAHAM BURTON; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; IUGR; Placental phenotype; Placental hyperplasia; Diabetes; IHPD; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi;

    Abstract : Placental development can be disturbed by various factors, such as mutation of specific genes or maternal diabetes. Our previous work on interspecies hybrid placental dysplasia (IHPD) and two additional models of placental hyperplasia, cloned mice and Esx1 mutants, showed that many genes are deregulated in placental dysplasia.

  4. 17. Sexually Dimorphic Gene Expression in the Mammalian Brain

    Author : Björn Reinius; Elena Jazin; Klas Kullander; Arthur Arnold; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Utvecklingsbiologi;

    Abstract : In recent times, major advances have been made towards understanding sexual dimorphism in the brain on a molecular basis. This thesis summarises my modest contributions to these endeavours. Sexual dimorphisms are manifested throughout the spectrum of biological complexity, and can be studied by numerous approaches.

  5. 18. Immunological aspects of maternal-foetal interactions in mice

    Author : Marie Arvola; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Neonatal mice; milk; placenta; fetal rejection; IgG; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; Developmental Biology; miljömedicinsk utvecklingsbiologi;

    Abstract : Mammalian pregnancy is an immunological paradox. The foetus, which expresses both paternal and maternal cell-surface molecules, has to be protected from rejection by the maternal immune system. At the same time, the mother has to have an efficient immune defence and must provide her offspring with antibodies. READ MORE

  6. 19. Chromatin regulators and transcriptional control of Drosophila development

    Author : Qi Dai; Mattias Mannervik; Albert J. Courey; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chromatin; Co-factors; Transcription; Development; Drosophila; Developmental biology; Utvecklingsbiologi; Developmental Biology; miljömedicinsk utvecklingsbiologi;

    Abstract : The development of a multicellular organism is programmed by complex patterns of gene expression. In eukaryotic cells, genes are packaged by histone proteins into chromatin. Chromatin regulators often function as transcription co-factors. READ MORE

  7. 20. Functions of Transcriptional Co-regulators in Drosophila development

    Author : Tobias Lilja; Mattias Mannervik; Ze'ev Paroush; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Transcription; Co-regulator; Development; Drosophila; Developmental biology; Utvecklingsbiologi; Developmental Biology; miljömedicinsk utvecklingsbiologi;

    Abstract : During Drosophila development, regulation of gene expression through interplay between transcriptional activators and repressors is generating complex patterns of gene expression that leads to cell differentiation. For proper control of transcription, transcription factors bind to DNA at control regions, so called Cis Regulatory Modules (CRM). READ MORE
