Role of endocytic trafficking during Dpp gradient formation
… demonstrated that the morphogen Decapentaplegic (Dpp) forms activity gradients by inducing the expression of several target genes above distinct concentration thresholds at different distances from the source. This way, Dpp contributes to developmental fates in the target field such as the …

The role of Decapentaplegic (Dpp) in Drosophila wing development
Decapentaplegic (Dpp), a member of the TGF-[Beta] superfamily, acts as a morphogen to direct cell differentiation, determine cell fate and promote cell survival and proliferation in Drosophila wing development. To investigate the role of Dpp in Drosophila wing development, three aspects of the …

Efficient sampling for determinantal point processes
Determinantal Point Processes (DPPs) are elegant probabilistic models of repulsion and diversity over discrete sets of items. It assigns higher probability to diverse subsets, making them more possible to be sampled. If we want to fully control the size of sampled subsets, the perfect choice would …

Functional and developmental characterisation of matrix binding sites in decapentaplegic
… pathways like hedgehog, wingless, FGF or dpp. In most cases it was, due to these pleiotropic effects, not possible to examine the relevance of matrix interactions for single pathways. The aim of this work was to examine the relevance of matrix interactions for the TGF-ß superfamily member …

Understanding the Structure-Property Relationship in Diketopyrrolopyrroles for Organic Electronics
… encapsulation and asymmetry of conjugated DPP-based polymers and small molecules were investigated. The first part of this thesis explored how chain length can affect the optical properties of conjugated DPP-based materials. Previously in our group, a series of thienyl-DPP oligomers (n = …

Promoter Specificity Mediates the Independent Regulation of Neighboring Genes
… neighboring Drosophila genes: decapentaplegic (dpp), SLY1 homologous (Slh) and out at first (oaf). Several dpp enhancers are positioned close to Slh and oaf and yet these genes are unaffected by the dpp elements. However, when a transposon is located within the oaf gene, the dpp enhancers …
