1. Protein Tyrosine Phosphatases as Regulators of Receptor Ryrosine Kinases
Sammanfattning : Tyrosine phosphorylation is a crucial mechanism in cellular signaling and regulates proliferation, differentiation, migration and adhesion. The phosphorylation reaction is reversible and is governed by two families of enzymes: protein tyrosine kinases and protein tyrosine phosphatases (PTPs). LÄS MER
2. Expression and Mutation Analyses of Candidate Cancer Genes In Situ
Sammanfattning : Cancers display heterogeneity in genetic profiles of the individual cancer cells and in the composition of different malignant and non-malignant cell populations. Such intra-tumor heterogeneity plays a role in treatment response and the emergence of resistance to cancer therapies. LÄS MER
3. Signaling for color change in melanophores : and a biosensor application
Sammanfattning : Melanophores are dark brown pigment cells located in the skin of fish, amphibia, reptiles, and many invertebrates. The color of the animal can change via rearrangement of pigment granules, melanosomes, in the cells. The dark melanophores can either hide colorful cells so that the animal appears dark, or let through colors from underneath. LÄS MER
4. Protein tyrosine phosphatases : taking a 'redoxionist' look at PDGFR signaling
Sammanfattning : Protein Tyrosine Phosphatases (PTPs) are oxidized and inactivated by reactive oxygen species (ROS) upon stimulation of a wide range of cell surface receptors, including the platelet-derived growth factor (PDGF) receptor (PDGF R). Signaling via this receptor tyrosine kinase stimulates cell proliferation and migration, and it is associated with cancer and cardiovascular diseases. LÄS MER
5. Expression and function of the protein tyrosine phosphatases SHP-1 and SHP-2 in prostate cancer
Sammanfattning : Prostate cancer is one of the most frequent cancers in males in Western countries. Radical prostatectomy serves as the first line of treatment for patients with localised prostate cancer. However, in many cases the cancer will recur. It is currently difficult to identify those patients at a high risk of tumour recurrence. LÄS MER
