Sammanfattning : Chromatin is a highly dynamic, regulatory component in the process of transcription, repair, recombination and replication. The BRG1 and SNF2H proteins are ATP-dependent chromatin remodeling proteins that modulate chromatin structure to regulate DNA accessibility for DNA-binding proteins involved in these processes.

2. Gene regulation by chromatin remodelling complexes : SWI/SNF complex in mRNA processing and B-WICH complex in ribosomal gene expression
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. Molecular mechanisms of embryonic stem cell pluripotency: transcription, telomere maintenance and proliferation
Sammanfattning : Somatic cell nuclear transfer and generation of induced pluripotent stem cells provide potential routes towards generation of patient specific embryonic stem (ES) cells. These procedures require induction of Oct4 gene expression, high telomerase activity and specific cell proliferation, characteristics shared with cancer stem cells. LÄS MER
Sammanfattning : Chromatin plays an important role in gene regulation, as it forms an obstacle for a number of proteins that need access to the DNA. Several protein complexes that open up the chromatin structure have been identified and some of these are important for gene regulation. LÄS MER
Sammanfattning : The implications of IGF-1R in normal development and disease are well established. IGF-1R plays pivotal roles in cell proliferation and cell survival and aberrant activation result in tumorigenesis and cancer progression. LÄS MER
