21. Genetic mechanisms regulating proliferation and cell specification in the Drosophila embryonic CNS
Sammanfattning : The central nervous system (CNS) consists of an enormous number of cells, and large cellular variance, integrated into an elaborate network. The CNS is the most complex animal organ, and therefore its establishment must be controlled by many different genetic programs. LÄS MER
22. Long Noncoding RNA Mediated Regulation of Imprinted Genes
Sammanfattning : Genomic imprinting is an epigenetic phenomenon that causes a subset of mammalian genes to be expressed from only one allele in a parent-of-origin manner. The defects in the imprinting regulation result in disorders that affect development, growth and metabolism. LÄS MER
23. Computational modelling in systems biology: from rewriting cell fates to detecting tumours
Sammanfattning : Computational modelling is becoming an increasingly important tool in biological research. By performing computer simulations of models, it becomes possible to test theories about a biological system against experimental data. Simulations can also be used as a replacement for experiments otherwise unattainable. LÄS MER
24. Epigenetic Control of Mammalian Development : Studies on an imprinting control region
Sammanfattning : A subset of autosomal genes is preferentially or exclusively expressed from one of the parental alleles. This phenomenon, termed genomic imprinting, is highlighted by the neighboring Igf2 and H19 genes, which are monoallelically expressed on opposite parental chromosomes. These features are governed by a 2. LÄS MER
25. Finding fitness : empirical and theoretical explorations of inferring fitness effects from population-level SNP data
Sammanfattning : The distribution of fitness effects (DFE) describes the likelihood that a new mutation has a specific effect on the fitness of an individual in a given population. The shape of the DFE is a result of several factors such as population size, mating system and selective environment, and can in turn influence the evolutionary potential of a species. LÄS MER
