Among the 16 patients who had either EPCAM or PSMA expression above the cut-off, only 25% (N=4) had high expression of both EPCAM and PSMA (Fig. 4D), suggesting that EPCAM and PSMA do not necessarily co-express in CTCs from HR and BCR PCa patients. The gene discussed is FOLH1; the disease is posterior cortical atrophy.
