As shown in Table 1, the results indicated that there was no significant difference of the frequency of RalA overexpression in these prostate tissues: PCa (85.3%, 29/34), BPH (61.5%, 16/26), CI (66.7%, 4/6) and normal prostate tissue (78.6%, 11/14). Here, RALA is linked to benign prostatic hyperplasia.
