abstract：:Two-dimensional protein gels were used to systematically assess changes in gene expression in Friend erythroleukemia cells after exposure to inducers of differentiation. A rapid decrease in expression of the stress protein HSP70 was observed after exposure to inducers. The kinetics of this change suggest that it may b...
