1. 6. Mitochondrial Iron Metabolism : Study of mitoferrin in Drosophila melanogaster

   Författare :Christoph Metzendorf; Maria Lind Karlberg; Kenneth Söderhäll; Martina Muckenthaler; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; iron; Drosophila; mitochondria; mitoferrin; ferritin; spermatogenesis; cell cycle; DFO; MRS12; Cell and molecular biology; Cell- och molekylärbiologi; Biology with specialization in Comparative Physiology; Biologi med inriktning mot jämförande fysiologi;

   Sammanfattning : Iron has a dualistic character. On the one hand it is essential for the life of most organisms, on the other hand it is involved in the generation of reactive oxygen species that are implicated in diseases and aging. LÄS MER

3. 7. Deciphering the Alk signaling pathway in Drosophila

   Författare :Fredrik Hugosson; Ruth H. Palmer; Osamu Shimmi; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Drosophila; Alk; RTK; visceral mesoderm; signal transduction; growth factor; transcription factor; molekylärbiologi; Molecular Biology;

   Sammanfattning : In Drosophila melanogaster the visceral mesoderm (VM) develops during embryogenesis in a process where myoblasts become specified to generate two distinct cell types, the founder cells (FCs) and the fusion competent myoblasts (FCMs) that consequently fuses. The cell specification is dependent on cell signaling mediated by the receptor tyrosine kinase (RTK) Anaplastic lymphoma kinase (Alk) and its ligand Jelly belly (Jeb), how this further sets up different identity programs that drive myoblasts to differentiate into FCs and FCMs is still not well understood.

4. 8. Regulators of chromatin and transcription in Drosophila

   Författare :Filip Crona; Mattias Mannervik; Fernando Azorin; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Transcription; chromatin; co-regulators; CBP; lysine demethylase; KDM4A; Brakeless; Drosophila; utvecklingsbiologi; Developmental Biology;

   Sammanfattning : Development of multicellular organisms is achieved by organized temporal and spatial patterns of gene expression leading to cell differentiation. Chromatin regulators control how the DNA is utilized by altering access of proteins to DNA and thereby function as co-factors in transcription. LÄS MER

5. 9. Midgut and muscle development in Drosophila melanogaster

   Författare :Margret Shirinian; Ruth Palmer; Anne Uve; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Drosophila; visceral mesoderm; endoderm; somatic muscles; Alk; C3G; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

   Sammanfattning : The fully developed and functional Drosophila midgut comprises two layers, the visceral mesoderm and the endoderm. The visceral muscle of the midgut is formed by the fusion of founder cells with fusion competent cells to form the muscle syncytia. LÄS MER
