The emerging role of phosphate in vascular calcification.

abstract：:Murine double minute (MDM)-2, an E3 ubiquitin ligase, promotes cancer cell survival and growth, by degrading the cell cycle regulator p53. Antagonism of MDM2 by the small-molecule cis-imidazoline nutlin analogs is under current study for cancer therapy. To test whether MDM2 also promotes regenerative cell growth, we d...
