1. Novel roles of ErbB3 receptor tyrosine kinase in vesicular trafficking
Sammanfattning : ErbB3 is a catalytically impaired receptor tyrosine kinase (RTK) from the EGFR family. Upon ligand binding, ErbB3 forms heterodimers with other members of the family and triggers phosphorylation cascades that promote crucial cellular functions as proliferation, differentiation and survival.

2. Novel Roles of the Ack1 Kinase in Epithelial Biology
Sammanfattning : Epithelial homeostasis is maintained through integration of diverse signals that regulate cell fate. A strict control of such signals is required to prevent overproliferation and, ultimately, oncogenesis. In this thesis we identify novel roles of Activated Cdc42-associated kinase 1 (Ack1) in maintenance of epithelial homeostasis. LÄS MER
3. Engineering strategies for ABD-derived affinity proteins for therapeutic and diagnostic applications
Sammanfattning : Small stable protein domains are attractive scaffolds for engineering affinity proteins due to their high tolerance to mutagenesis without loosing structural integrity. The albuminbinding domain is a 5 kDa three-helix bundle derived from the bacterial receptor Protein G with low-nanomolar affinity to albumin. LÄS MER
4. Functional analysis of Ipf1/Pdx1, MFng and Id during pancreatic growth and differentiation
Sammanfattning : The pancreas is an endodermally derived organ consisting of three major cell lineages. The endocrine cells, organised into the Islets of Langerhans, regulate blood glucose homeostasis by producing and secreting hormones such as glucagon and insulin into the bloodstream. LÄS MER
5. Experimental studies in brain tumours : with special regard to multidrug resistance and the ErbB-family
Sammanfattning : Primary brain tumours, and especially the most common form malignant gliomas, usually display a pronounced resistance to other treatment modalities when surgery fails to cure. Growth factors, such as EGF and its receptor, frequently amplified and overexpressed in malignant gliomas, and factors associated with multidrug resistance have been suggested to at least partially explain the poor outcome.
