Modulation of eicosanoid production by human alveolar macrophages exposed to silica in vitro.

abstract：:The progression of the cell cycle is controlled by the action of both positive and negative growth regulators. The key players in this activity include a family of cyclins and cyclin-dependent kinases, which are themselves regulated by other kinases and phosphatases.
