Activation of protein kinase A increases the in vitro invasion, migration, and adherence to reconstituted basement membrane by Lewis lung carcinoma tumor cells.

Prostaglandin E2 (PGE2) stimulated in vitro invasion, migration, and adherence to reconstituted basement membrane by metastatic Lewis lung carcinoma (LLC) clones, but this stimulation was blocked by protein kinase A (PKA) inhibitors and by expression of a transfected mutant RI alpha which blocks PKA activation. In vitro migration and adherence of metastatic LLC transfectants was heightened by expression of a transfected C alpha gene and further heightened by Zn2+ induction of the expression vector. Nonmetastatic LLC were not migratory nor invasive. However, nonmetastatic LLC that were stably transfected with a C alpha gene were both migratory and invasive, particularly when C alpha expression was further induced with Zn2+. The results of these in vitro studies show that PKA can enhance the metastatic characteristics of LLC.[1]
