1. 21. Gene Regulatory Networks: Dynamics and Stability

   Författare :Carl Troein; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; systems; control; Datalogi; numerisk analys; system; kontroll; Computer science; numerical analysis; Fysik; biomathematics biometrics; Bioinformatik; medicinsk informatik; biomatematik; Physics; medical informatics; transcriptional regulation; gene regulatory networks; Bioinformatics; signaling pathway profiling; stem cell regulation; metabolic pathway; fitness; nested canalyzing rules; Kauffman networks; random Boolean networks; Fysicumarkivet:2007:Troein;

   Sammanfattning : Life as we know it is based on cells that use proteins and RNA to carry out metabolism, self-replication, and other essential tasks. The genes that code for these molecules are encoded in DNA, and through the processes of transcription and translation the cell expresses its genes. LÄS MER

3. 22. Chromatin remodelling and gene regulation

   Författare :Birgitta Gelius; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   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

4. 23. Naturally derived cell-penetrating peptides and applications in gene regulation : A study on internalization mechanisms and endosomal escape

   Författare :Pontus Lundberg; Ülo Langel; Bernard Lebleu; Stockholms universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; peptide; oligonucleotide; endocytosis; gene regulation; Neurochemistry; Neurokemi;

   Sammanfattning : Cell-penetrating peptides are a class of peptides which have achieved a lot of recognition due to their vector abilities. Since their discovery over a decade ago, there has been an uncertainty concerning the mechanism by which they are internalized into the cells. LÄS MER

5. 24. CANCER-RELATED GENE REGULATION MECHANISMS

   Författare :Srinivas Veerla; Avdelningen för klinisk genetik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : Cancer is a disease characterized by deregulation of cellular functions. The means by which these changes occur may differ among cancer types. However, common to all cancers are that they have changed the genetic programs that determine their characteristics. Genetic programs are mainly regulated by the action of transcription factors.

7. 25. Plant UDP-glucose Pyrophosphorylase : Function and Regulation

   Författare :Meng Meng; Leszek Kleczkowski; Javier Pozueta-Romero; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; UDP-glucose pyrophosphorylase; carbohydrate metabolism; in vivo regulation; T-DNA knockout; heterologous expression; isozyme; mutagenesis; kinetic property; oligomerization; Plant physiology; Växtfysiologi;

   Sammanfattning : UDP-glucose pyrophosphorylase (UGPase) is an important enzyme of carbohydrate metabolism in all living organisms. The main aim of this thesis was to investigate the function and regulation of plant UGP genes as well as the UGPase proteins. LÄS MER
