1. Studies of neuropeptides in pancreatic beta cell function with special emphasis on islet amyloid polypeptide (IAPP)Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis
Sammanfattning : The presence of protein amyloid in pancreas and its association to diabetes was first described 100 years ago in 1901, but was not identified as Islet Amyloid Polypeptide (IAPP) until 1986. The aim of the present work was to determine the role of the beta cell hormone, IAPP, in normal pancreatic islet physiology and during early disturbances of islet function. LÄS MER
- Detta är en avhandling från Göteborg : Intellecta Infolog AB
Sammanfattning : Transforming Growth Factor Beta (TGF-β) is a cytokine regulating a wide range of cellular processes such as proliferation, differentiation, and migration. At the early stages of cancer development TGF-β functions as a tumor suppressor, mainly due to its inhibitory effect on cellular growth, but during cancer progression, mutations in TGF-β signal components switches TGF-β into a promoter of cancer cell proliferation, survival and metastasis.

3. Genetic pathways controlling CNS development The role of Notch signaling in regulating daughter cell proliferation in DrosophilaDetta är en avhandling från Linköping : Linköping University Electronic Press
Sammanfattning : The human central nervous system (CNS) displays the greatest cellular diversity of any organ system, consisting of billions of neurons, of numerous cell sub-types, interconnected in a vast network. Given this enormous complexity, decoding the genetic programs controlling the multistep process of CNS development remains a major challenge. LÄS MER
4. Genetic mechanisms regulating proliferation and cell specification in the Drosophila embryonic CNSDetta är en avhandling från Linköping : Linköping University Electronic Press
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
- Detta är en avhandling från Department of Laboratory Medicine, Lund University
Sammanfattning : Two key events in the oncogenic process of tumor cells are to acquire uncontrolled proliferation and invasive properties. This allows the tumor to grow and invade beyond the tissue from which the tumor cells originate. LÄS MER
