  1. 6. microRNAs: from biogenesis to organismal tracing

    Författare :Wenjing Kang; Marc Friedländer; Jens Lagergren; Ulf Ørom; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; microRNA; microRNA biogenesis; taxonomical identification; high throughput sequencing; xenomiRs; RNA structure; high throughput screening; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : MicroRNAs (miRNAs) are short noncoding RNAs of around 22 nucleotides in length, which help to shape the expression of most mRNAs. Perturbation of miRNA expression has revealed a variety of defects in development, cell specification, physiology and behavior. LÄS MER

  3. 7. Evolution of acetylcholine receptors and study of the anatomy of the mouse brain reward system

    Författare :Julia Pedersen; Dan Larhammar; Arnaud Chatonnet; Uppsala universitet; []

    Sammanfattning : A balanced tear film is essential for a healthy ocular surface. Insufficient tear production may result in dry eye, a common disorder in the elderly population. Dry eye causes significant discomfort in the patients and may lead to visual impairment and ocular infections. LÄS MER

  5. 9. Single-cell RNA sequencing as a tool to study panarthropod evolution

    Författare :Brenda Irene Medina Jimenez; Ralf Janssen; Graham Budd; Tatjana Haitina; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Single-cell RNA sequencing; EvoDevo; gene expression; tissue dissociation; cell capture; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Sammanfattning : Panarthropoda is a monophyletic group comprised of arthropods and lobopods, molting animals with a segmented body, paired appendages, dorsal brain, and ventral nerve cords. Evolutionary Developmental Biology (EvoDevo) is an interdisciplinary field that seeks to understand how changes in development form the basis for variations in morphology and phenotypic evolution, including the genetic network underlying these processes.
