1. Studies on the biological functions of interaction between components in Wnt, TGF-β and HIF pathways for cancer progression
Sammanfattning : Cancer is a disease that involves aggressive changes in the genome and aberrant signals between the living cells. Signalling pathways such as TGF-β (Transforming growth factor-β), Wnt, EGF (epidermal growth factor) and HIF (Hypoxia-inducible factor) evolved to regulate growth and development in mammals. LÄS MER
2. Making neurons from stem cells : molecular mechanisms and spider silk substrates
Sammanfattning : The understanding of the function of the nervous system and the brain is one of the major intellectual challenges in life sciences. Neurological and psychiatric disorders are in addition major issues for the society, and new approaches are needed to learn more about the brain and to develop new treatments. LÄS MER
3. Wnts in development : focus on midbrain
Sammanfattning : Studies in the field of embryonic development reveal the temporal and spatial requirement of specific genes/proteins in the formation of a given tissue. The specific knowledge of which genes/proteins regulate development of the ventral midbrain (VM) provides a guideline for the in vitro differentiation of specific cell types therein, such as dopaminergic (DA) neurons.

4. From stem cells to neurons : a BMPy ride
Sammanfattning : Pinpointing the mechanisms behind the formation of the vertebrate development has been an intriguing and challenging task for researchers for several decades. In the 1980s two independent groups managed to isolate cells from the inner cell mass of a mouse blastocyst and to culture and expand them in vitro, while maintaining their pluripotency. LÄS MER
5. Regulation of postnatal neurogenesis and brain angiogenesis by thyroid hormone
Sammanfattning : Thyroid hormone (TH), which is secreted by the thyroid gland, exerts significant effects on the central nervous system (CNS), especially during development, so that delayed treatment of perinatal hypothyroidism results in severe cognitive retardation. Continuous postnatal neurogenesis occurs throughout adulthood in the subventricular zone (SVZ) of the lateral ventricle wall and in the subgranular zone (SGZ) of the dentate gyrus (DG) of the hippocampal formation.
