RNA-mediated gene duplication: the rat preproinsulin I gene is a functional retroposon.

abstract：:Apoptotic cells are swiftly engulfed by macrophages to prevent the release of noxious materials from dying cells. Apoptotic cells expose phosphatidylserine (PtdSer) on their surface, and macrophages engulf them by recognizing PtdSer using specific receptors and opsonins. Here, we found that mouse resident peritoneal m...
