In LMP tumours, the levels of MCM proteins did not correlate with either p27Kip1 or p21WAF1 in keeping with our previous observations concerning Ki-67, p21WAF1 and p27Kip1 expression in LMP ovarian tumours (Korkolopoulou et al, 2002, Vassilopoulos et al, 2003). The gene discussed is CDKN1B; the disease is ovarian neoplasm.
