  1. 1. Gene regulation by chromatin remodelling complexes : SWI/SNF complex in mRNA processing and B-WICH complex in ribosomal gene expression

    Författare :Antoni Gañez Zapater; Ann-Kristin Östlund-Farrants; Christopher W.J. Smith; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chromatin remodelling; SWI SNF; Brg1; Brm; alternative splicing; cleavage and polyadenylation; B-WICH; WSTF; ribosomal genes; Cell Biology; cellbiologi;

    Sammanfattning : The aim of this project is to investigate the roles of chromatin remodelling complexes in gene regulation. It is focused on two groups of chromatin complexes: the mammalian BRG1 and BRM SWI/SNF complexes and the ISWI-containing B-WICH complex.Study 1 investigates the role of SWI/SNF complexes in alternative splicing.

  3. 2. ATPase dependent and independent roles of Brahma in transcription and pre-mRNA processing

    Författare :Simei Yu; Neus Visa; Ann-Kristin Östlund Farrants; Christian Muchardt; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; chromatin remodeling; transcription; alternative splicing; 3 -end processing; Molecular Biology; molekylärbiologi;

    Sammanfattning : SWI/SNF is a chromatin-remodeling complex and Brahma (BRM) is the ATPase subunit of SWI/SNF. BRM regulates transcription by remodeling the nucleosomes at promoter regions. BRM is also associated with RNA and affects pre-mRNA processing together with other SWI/SNF subunits. LÄS MER

  4. 3. The SWI/SNF complex : Roles in transcription and pre-mRNA processing

    Författare :Johan Waldholm; Neus Visa; Ann-Kristin Östlund; Silvia Barabino; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Splicing; Gene regulation; SWI SNF; polyadenylation; Molecular Biology; molekylärbiologi;

    Sammanfattning : The regulation of gene expression is fundamental to the development of complex organisms and an important driving force in this process. When and where the genes are expressed decide the fate of a cell and its physiological context in the organism. LÄS MER

  5. 4. 60 GHz Mixer and Multifunctional MMICs in GaAs pHEMT and mHEMT technologies

    Författare :Sten Gunnarsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Image reject mixer; Broadband wireless communication; Single-chip; Multifunctional; Mixer; Balanced resistive mixer; GaAs; Dual-quadrature mixer; 60 GHz; Receiver; pHEMT; MMIC; High data-rate; Double balanced Gilbert mixer; mHEMT; Transmitter; V-band;

    Sammanfattning : In recent years, the 60 GHz band has gained increased academic and commercial interest mainly due to the relative large amount of license free and little used frequency spectrum located in vicinity of 60 GHz. The exact locations of these free frequency bands varies locally but the 5962 GHz band overlap around the world and is therefore a true world wide license free band. LÄS MER
