Corrigendum: Berberine Improves Benign Prostatic Hyperplasia via Suppression of 5 Alpha Reductase and Extracellular Signal-Regulated Kinase in Vivo and in Vitro

In the original article, there was a mistake in the legend for Figure 1 as published. The magnifications of Figure 1A were stated as ×100 and × 400, when they were actually × 200 and × 400. The correct legend appears below.

Figure 1.

Effect of BBR on histological changes and protein expression of PSA in prostate tissues of TP-induced BPH rats. (A) Representative photomicrographs of H&E stained prostate tissues (left panels, magnification ×200; right panels, magnification ×400) are shown. (B) The epithelial thickness and (C) the relative lumen area of the prostate tissues were measured using Image J software. Values are mean ± S.D. of ten or more separate measurements. (D) The protein expression of PSA was analyzed by a western blot analysis. Values are mean ± S.D. of three or more separate measurements. ^#P < 0.05 when compared to NC; ^*P < 0.05 when compared to BPH. The protein expression differences are normalized to GAPDH. NC, normal control group; BPH, TP-induced BPH group; BBR, BBR-treated BPH group; Fi, finasteride-treated BPH group.

In the original article, there was a mistake in Figure 1 as published. The wrong photomicrographs of prostate tissues were presented by mistake. The corrected Figure 1 appears below. The authors apologize for this error and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.
