1. The Interaction of the Adenovirus E1B-55K Protein with a Histone Deacetylase Complex: Its Importance in Regulation of P53 Protein Functions
Sammanfattning : The human tumour suppressor protein p53 is an effective inhibitor of cell growth, by inducing cell cycle arrest and apoptosis. However, p53-induced cell growth inhibition can be detrimental for virus multiplication. Therefore, viruses encode for proteins, which can interfere with the functions of the p53 protein. LÄS MER
2. Tumor Selective Antiproliferative Naphthoxylosides
Sammanfattning : Proteoglycans (PG) are highly anionic macromolecules consisting of a core protein covalently substituted with long unbranched polysaccharide chains called glycosaminoglycans (GAGs). PGs are central components in multicellular organisms, and they may occur in the extracellular matrix (ECM), at the cell surface, or in the secretory pathway. LÄS MER
3. Genome-wide patterns of histone modifications in fission yeast
Sammanfattning : DNA is wrapped almost two times around a group of proteins called histones to form a chromosomal structure known as the nucleosome. Both DNA and histones can be modified with different chemical tags by several enzymes to activate or suppress a particular gene or group of genes. Histones can be covalently modified at several places. LÄS MER
4. Gene regulation during development by chromatin and the Super Elongation Complex
Sammanfattning : Developmental processes are carefully controlled at the level of transcription to ensure that the fertilized egg develops into an adult organism. The mechanisms that controls transcription of protein-coding genes ultimately ensure that the Pol II machine synthesizes mRNA from the correct set of genes in every cell type. LÄS MER
5. On histone deacetylases in the epigenetic regulation of neural stem and cancer cell fate
Sammanfattning : Development of an organism requires correct spatial and temporal regulation of gene expression. Epigenetic regulation of gene expression has been shown to be an important part of many cellular events. Nucleosomes consist of two subunits of each core histone proteins H2A, H2B, H3, H4, and 146 base pairs of DNA, wrapped around the histones. LÄS MER
