1. Integrin Signaling in Cell Adhesion and Mechanotransduction : Regulation of PI3K, AKT, and ROS
Sammanfattning : Integrins are a family of conserved cell surface receptors found throughout the animal kingdom. They comprise 24 dimers in mammals, and regulate a number of processes including cell survival, differentiation, and migration. LÄS MER
2. Colorectal cancer and radiation response : The role of EGFR, AKT and cancer stem cell markers
Sammanfattning : The primary treatment for colorectal cancer is surgery. Radiotherapy and chemotherapy, sometimes combined, are also frequently used to diminish recurrence risk. In response to radiation exposure, several cellular signaling cascades are activated to repair DNA breaks, prevent apoptosis and to keep the cells proliferating. LÄS MER
3. Regulation of Apoptosis in Hematopoietic Progenitor Cells: Involvement of Different Signaling Pathways
Sammanfattning : Proliferation, differentiation, and survival of hematopoietic stem cells and multipotent progenitor cells are regulated by cytokines and cell-cell interactions. Kit ligand (KL) and Flt3 ligand (FL) have pleiotropic effects, promotes survival, but are nonredundant. LÄS MER
4. Adhesion Dependent Signals : Cell Survival, Receptor Crosstalk and Mechanostimulation
Sammanfattning : The integrin family of cell surface receptors is evolutionary conserved and found in all multicellular animals. In humans 8-alpha and 18-beta integrins are non-covalently associated into 24 dimers. Integrins mediate cell-extracellular matrix and cell-cell interactions and participate in cell signalling.

5. Molecular mechanisms for activation of non-canonical TGFβ pathways and their importance during prostate cancer progression
Sammanfattning : Prostate cancer is the most common invasive cancer diagnosed in men and a major and growing health problem in Western countries. Deregulation of different pathways has been implicated in progression of prostate cancer, namely nuclear factor kappa enhancer binding protein (NF-κB), transforming growth factor β (TGFβ), phosphoinositide 3ʹ-kinase/AKT (PI3K/AKT) and Src kinase pathways.
