6. 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
7. The Impact of Tryptase and Epigenetic Mechanisms on Mast Cells
Sammanfattning : Mast cells have a large influence on multiple immune-mediated responses, including allergic conditions, and they have been implicated in various diseases such as arthritis and cancer. Mastocytosis is characterized by abnormal mast cell proliferation induced by mutations in KIT, the stem cell factor (SCF) receptor. LÄS MER
8. Epigenetic Regulation of Gene Transcription in Hematopoietic Tumors
Sammanfattning : Epigenetic modifications were shown to play an essential role in tumorigenesis. Epigenetic mechanisms can alter transcription in several ways, through DNA methylation and/or through histone modification. DNA methylation at the TSS (transcriptional start site) has been implicated in tumor development and gene silencing. LÄS MER
9. Mining DNA elements involved in targeting of chromatin modifiers
Sammanfattning : Background: In all higher organisms, the nuclear DNA is condensed into nucleosomes that consist of DNA wrapped around a core of highly conserved histone proteins. DNA bound to histones and other structural proteins form the chromatin. LÄS MER
10. Search for molecular and metabolic mechanisms contributing to impaired β-cell function
Sammanfattning : Type 2 Diabetes (T2D) prevalence is growing to pandemic proportions worldwide. The link between genotype, environment and β-cell function is still being investigated. LÄS MER
