Changes in hepatic RNA, poly(A)+RNA, and poly(A)-RNA during the acute phase response to inflammation
Abstract:
The steady state changes in total rat hepatic cytoplasmic RNA, poly(A)+ RNA and poly(A)-RNA were assessed in response to turpentine induced inflammation. From 18 to 24 h after injury, cytoplasmic RNA doubled, while poly(A)+ RNA peaked at 24 h, 3.5 times over control animals. Cell-free translation showed significant increases in messenger RNA levels beginning at 18 h. Gel electrophoresis of translation products revealed significant increases in several polypeptides and a decrease in others. Poly(A)-RNA from control and injured rats translated to an insignificant level and the electrophoretic gel patterns of their proteins were similar. Furthermore, no change had occurred in the 3' poly(A)-sequences during the course of inflammation.
