Stimulation of mitogen activated protein kinase by LDL and oxLDL in human U-937 macrophage-like cells.

abstract：:The role of p53 as the "guardian of the genome" in differentiated somatic cells, triggering various biological processes, is well established. Recent studies in the stem cell field have highlighted a profound role of p53 in stem cell biology as well. These studies, combined with basic data obtained 20 years ago, provi...
