Of the 8 genes in UPUP group, five genes (B3 DNA binding domain containing protein, HSP DnaJ protein-putative, aminotransferase domain containing protein, emp24/gp25L/p24 family protein and CutA, chloroplast precursor-putative) displayed distinct upregulation (≥ 2 fold) in both TR3RR and TR94RR against both BPH and WBPH; against BPH in TR145RS and against WBPH in TR152SR at one or both the time points (Fig. 7, panels 1 to 5). This evidence concerns the gene HSP90B2P and benign prostatic hyperplasia.
