LRP6 protein regulates low density lipoprotein (LDL) receptor-mediated LDL uptake.

Genetic variations in LRP6 gene are associated with high serum LDL cholesterol levels. We have previously shown that LDL clearance in peripheral B-lymphocytes of the LRP6(R611C) mutation carriers is significantly impaired. In this study we have examined the role of wild type LRP6 (LRP6(WT)) and LRP6(R611C) in LDL receptor (LDLR)-mediated LDL uptake.

The cell growth is controlled by the interaction of survival and cell growth arrest pathways as well as apoptosis mechanisms which determine the outcome of cell faith as proliferation or apoptosis. In this study, we have studied the activity of survival pathways, i.e.
