Previous studies have implicated adenosine 3',5'-cyclic monophosphate (cAMP)-dependent protein kinase (PKA) in regulation of both growth and expression of differentiated function in the pig renal epithelial cell, LLC-PK1. To investigate this possible regulatory mechanism, we compared growth behavior, morphology, and appearance of two differentiated functions, Na-hexose symport (SYMP) and gamma-glutamyl transpeptidase (gamma-GT), in the LLC-PK1 line and two PKA-deficient mutants (FIB4 and FIB6). Compared with the wild-type cell line, the mutant lines continued to proliferate at higher population densities and exhibited altered cell morphology, poorer formation of the brush-border structure, and decreased or lack of expression of SYMP and gamma-GT activities. Wild-type and mutant cells exhibit an identical logarithmic growth rate. Both lines form cell-cell junctions and exhibit identical kinetic properties of expressed SYMP activity. These results strongly support the hypothesis that PKA modulates a defined subset of cellular processes, including aspects of growth control and expression of the differentiated phenotype, in this renal epithelial cell line.
