21. Profilin : From the Cell Edge into the Nucleus
Sammanfattning : Internal and external signaling dependent changes in cell behavior are directly linked to force-generating remodeling of the actin microfilament system which is juxtaposed to the inside of the plasma membrane. This dynamic filament system is involved in many processes in the cytoplasm and the nucleus of eukaryotic cells. LÄS MER
22. Roles of membrane vesicles in bacterial pathogenesis
Sammanfattning : The production of membranous vesicles is observed to occur among organisms from all domains of the tree of life spanning prokaryotes (bacteria, archaea) and eukaryotes (plants, animals and fungi). Bacterial release of membrane-derived vesicles (MVs) has been studied most extensively in cases of Gram-negative species and implicating their outer membrane in formation of extracellular MVs.

23. Gene expression studies of pregastrulation development: the basement membrane is essential for cell differentiation
Sammanfattning : Basement membranes (BMs) are sheet-like structures of extracellular matrix. They act as a supporting structure but can also significantly influence cellular behavior in development, tissue homeostasis and disease. Laminins, a major BM component, are multidomain proteins, consisting of three polypeptide chains (α, β and γ). LÄS MER
24. The role of Smad7 and TRAF6 in Prostate Cancer Cell Invasion, Migration and Survival
Sammanfattning : Transforming growth factor (TGF) β is a tumor suppressor during early tumor development, by inhibiting proliferation and inducing apoptosis. At later stages of cancer, it becomes a tumor promoter, and promotes tumor cell migration and invasion. TGFβ signals via its type II and type I receptors to several downstream signaling pathways.

25. Membrane lipids and their transfer proteins in β-cells
Sammanfattning : Insulin secretion from β-cells is essential for glucose homeostasis and is often dysregulated in diabetes. Intracellular Ca2+ and membrane lipids cooperate to control insulin secretion with high spatial and temporal precision. LÄS MER
