Proliferating cell nuclear antigen (PCNA) is a 36-Kd nuclear protein,
identified as the auxiliary protein of DNA polymerase delta, that is
upregulated in activated proliferating cells from a variety of tissues and
species, including human lymphocytes. We have examined by two- dimensional
polyacrylamide gel electrophoresis the expression of PCNA in various
subtypes of childhood acute leukemia and have found differences in its
expression according to subtype. These differences were not related to the
initial peripheral white blood count, age, or sex, and appeared to reflect
differences in proliferative activity between subtypes of acute leukemia.
