“Short incubation of hepatocytes with amiodarone (50 microM), 4,4'-diethylaminoethoxyhexestrol (50 microM) or perhexiline maleate (25 microM) increased the pool of CK8 monomers and increased cell calcium to activate Ca(++)-dependent transglutaminases which cross-linked the CK8 monomers into CK8-containing oligomers.”
