1. 26. Regulation of HIV-1 provirus transcription

   Författare :Mojgan H Naghavi; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Key words- HIV-1; LTR; transcription; subtypes; phylogenetic analysis; NFkappaB; USF; MCEF; HMG-1 DSP1; Dorsal.;

   Sammanfattning : Transcription of the HIV-genome is regulated by the interaction of viral long terminal repeat (LTR) cis-acting sequences with a complex of viral regulatory proteins and cellular transcription factors. The complex interplay between the cellular-, and/or viral proteins and LTR of different subtypes may play a role in the control of HIV-1 latency versus activation. LÄS MER

3. 27. Topology Prediction of α-Helical Transmembrane Proteins

   Författare :Christoph Peters; Arne Elofsson; Pier Martelli; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; biokemi;

   Sammanfattning : Membrane proteins fulfil a number of tasks in cells, including signalling, cell-cell interaction, and the transportation of molecules. The prominence of these tasks makes membrane proteins an important target for clinical drugs. LÄS MER

4. 28. Sex chromosomes in willows : evolutionary studies of the ZW sex chromosome system in Salix viminalis

   Författare :Pascal Pucholt; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Sexual reproduction is found in most eukaryotes and has in the majority of animal species led to the evolution of separate sexes. In contrast, only 5-6% of all angiospersms are dioecious with female and male flowers on separate individuals. Interestingly, dioecy has evolved hundreds of times independently and at different timepoints in angiosperms. LÄS MER

5. 29. Hfq- and sRNA-mediated regulation in Neisseria meningitidis

   Författare :Jens Karlsson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Neisseria meningitidis, also known as the meningococcus, is a human-specific pathogen that commonly colonises the nasopharynx without causing disease. For reasons unknown, N. meningitidis can traverse the nasopharyngeal epithelium and enter the bloodstream, causing invasive meningococcal disease manifesting in septicaemia and/or meningitis.

7. 30. Modulation of cellular and viral functions in Epstein-Barr virus infected cells

   Författare :Marta P Imreh; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : The aim of the study was to investigate the interplay of cellular and viral genes in Epstein-Barr virus (EBV) infected cells. Two aspects of this interaction have been investigated. The first aspect is related to the expression of major histocompatibility complex (MHC) class I molecules in virus infected malignant cells.
