Q

DBr3

A

These cells are cAMP deficient cells. In comparison to MDCK cells, these cells have reduced Na/K ATPase biosynthesis in response to PGE1. However they have retained PGE1 responsiveness on cell growth. The regulation is post-transcriptional.

Q

PGE1 Ind

A

These cells are variant MDCK cells that have lost the growth responsiveness to PGE1 but not the responsiveness of PGE1 on Na/K ATPase biosynthesis as compared to MDCK. They have very high levels of cAMP. The regulation is post-transcriptional.
