Role of PKCα and -δ in LG1- and Ln2-P3-induced cell adhesion. A and B, Gö6976, a PKCα inhibitor, did not inhibit adhesion of PC12 cells seeded on rLG1- or Ln2-P3-coated plates, but rottlerin, a PKCδ inhibitor, significantly inhibited cell adhesion. PC12 cells were pretreated with Gö6976 or rottlerin for 15 min at 37 °C and seeded on rLG1- or Ln2-P3-coated plates for 1 h in serum-free medium. Values are expressed as a percentage of the value for cells pretreated without Gö6976 or rottlerin (mean ± S.D., n = 3). *, p < 0.01.
