In addition, selected cortical cysts (approximately 5% of all cysts) were strongly positive for p50, as shown in the high‐power view in Figure 8E. However, the localization and intensity of p50 immunoreactivity were similar between LPK + vehicle and LPK + PDTC (40 × 2) (Fig. 8C–F). The gene discussed is NFKB1; the disease is Renal cortical cysts.
