  1. 21. Size matters : RNA silencing processes in Phytophthora infestans

    Författare :Anna Åsman; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Non-coding RNAs do not encode proteins but instead function through their own RNA sequence. These molecules range from several thousands of nucleotides (nt) in length down to around 20 nt. Specifically, small RNAs (sRNAs) have critical functions in eukaryotic cells, despite being only 20-30 nt long. LÄS MER

  3. 22. Regulatory roles of sRNAs in pathogenesis of Vibrio cholerae

    Författare :Dharmesh Sabharwal; Sun Nyunt Wai; Bernt Eric Uhlin; Jörgen Johansson; Cynthia Sharma; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Vibrio cholerae; sRNA; Biofilm; OmpT; RbmC; Vrp; VafA; mikrobiologi; Microbiology;

    Sammanfattning : The Gram-negative pathogen Vibrio cholerae uses variety of regulatory molecules to modulate expression of virulence factors. One important regulatory element of microorganisms is small non-coding RNAs (sRNAs), which control various cell functions such as expression of cell membrane proteins, mRNA decay and riboswitches.

  4. 23. Adenoviral Control of RNAi/miRNA Pathways in Human Cells

    Författare :Ning Xu; Göran Akusjärvi; Fredrik Söderbom; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adenovirus; RNAi; miRNA; VA RNA; Virology; Virologi;

    Sammanfattning : RNA interference (RNAi) is a diverse, conserved regulatory mechanism in eukaryotic cells, which silences the target gene expression in a homology-dependent manner. Although it has been well documented that RNAi is an antiviral mechanism in plants and insects, it is still unclear whether RNAi naturally limits viral infections in vertebrates. LÄS MER

  5. 24. Into the Single-Verse : Subtle gene expression differences between virtually identical single cells are informative of gene regulation

    Författare :Marcel Tarbier; Marc Friedländer; Nils Blüthgen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Single-cell; quantitative; RNA biology; miRNA; functional genomics; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : The ability to profile transcriptomes and proteomes in a high-throughput fashion in single cells has truly revolutionized functional genomics, and countless functional and regulatory insights have been based on these technologies. While major applications include the discovery of new cell types and the a posteriori sorting of cell populations, studies of gene expression noise and gene co-expression have made use of this inter-cellular heterogeneity in a genuine quantitative fashion.

  7. 25. Structural and Functional Studies of Wilms Tumour Protein - WT1; Novel Insights into Functionality of Zinc Finger Proteins

    Författare :Elmar Nurmemmedov; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Naturvetenskap; Natural science; function; structure; transcription factor; cancer; affinity; kinetics; Biacore; RNA binding; DNA binding; Wilms tumour WT1 ; zinc finger;

    Sammanfattning : The molecular process under which message in DNA is relayed onto RNA is called transcription, and it accomplished through involvement of so-called transcription factors. Zinc finger proteins are one of the most abundant classes of regulatory proteins in eukaryotic cells where they play central roles in a variety of cellular activities. LÄS MER
