Our analysis revealed that the expression levels of DACH1 and CACNA1D in BPH tissues were significantly higher than those in normal prostate tissues, whereas the expression levels of STARD13 and RUNDC3B were significantly lower in BPH tissues compared to normal prostate tissues (Figures 9A–D, Table 1). The gene discussed is CACNA1D; the disease is benign prostatic hyperplasia.
