Changes in the expression of cell cycle regulators were categorized into early and mid-to-late events. RESULTS and CONCLUSIONS: Early events included a decrease in androgen receptor expression, followed by a short-term increase in expression of the p53 and p21/WAF1 proteins and a marked decrease in the Ki67 proliferative index." . .
