摘要：The changes of protein kinases (PKs) in the nuclear matrix of HL-60 cells during the differentiation by retinoic acid (RA) were examined by in situ assay after sodium dodecyl sulfate-polyacrylamide gel electrophoresis. In the nuclear matrix of HL-60, at least seven species of PKs (83, 63, 58, 46, 42, 38, and 31 kDa) were always detected. Among these PKs, 63 kDa PK was increased dramatically during differentiation by RA. Two-dimensional electrophoresis revealed that two species of 63 kDa PKs (pI 5.0 and 5.4) were presented in the nuclear matrix and increased similarly during the differentiation. This increase of 63 kDa PKs may be related to the lobulation of the nucleus and the nuclear matrix accompanying the differentiation by RA.
