We investigated the metabolite changes of Morus roots (MRs) according to different cultivar families (Simheung, Daesim, Cheong-il, Sangchon, Daeseong, Suhong, Suwon, and Igsu) using ultra-performance liquid chromatography–quadrupole time-of-flight mass spectrometry (UPLC–QTOF-MS) to understand the relationship between different cultivars and metabolite changes. Data were analyzed by partial least squares discriminant analysis (PLS-DA), and samples were successfully separated in PLS-DA scores. Eight metabolites in the electrospray ionization (ESI)-positive mode and 16 metabolites in the ESI-negative mode contributed to the separation in PLS-DA. Our data suggest that comparative analysis of MR metabolites according to different cultivars is useful to better understand the relationship between the different cultivars and metabolite changes. Furthermore, we analyzed the MRs for their ability to improve benign prostatic hyperplasia (BPH). LNCaP cells were used to evaluate the prostate-specific antigen (PSA) inhibitory activity of MRs, and, amongst them, the extract with the highest activity was selected. Igsu demonstrated the highest inhibition effect of prostate-specific antigen (PSA) expression among the MR cultivars. Igsu was also evaluated by administration in a testosterone-induced benign prostatic hyperplasia model in Sprague-Dawley rats. Igsu was shown to ameliorate BPH as evidenced by the prostate index, expression of androgen receptor (AR) signaling-related protein, growth factors, cell proliferation-related proteins, apoptosis-related proteins, mitogen-activated protein kinase (MAPK) signaling proteins, and histological analysis. Hence, this study strongly suggests that Igsu may have a beneficial effect of on BPH.

Abstract  Benign prostatic hyperplasia (BPH) is one of the most common benign tumors in men with prevalence ranging from 50% for men in their 60s to 90% for men in their 80s. The researcher sought to determine the relationship of prostate-specific antigen (PSA) and prostate volume in patients with benign prostatic hyperplasia. This study was based on 33 cases of benign prostatic hyperplasia in the Department of Urology, RSUD Dr. Soetomo Surabaya that diagnosed by histopathology examination. Cases with malignancy, acute urinary retention and prostatitis were excluded. The variables of prostate-specific antigen and prostate volume were examined. The results of this study found that 33 men were enrolled with mean PSA 16,04 ng/ml and a mean prostate volume of 49,13 ml. Overall, 84,8% had PSA level >4 ng/ml and 90,9% had prostate volume >25 ml. Prostate-specific antigen has significant correlation with prostate volume (p=0,019; r=0,362). This study concluded that prostate-specific antigen and prostate volume showed a significant correlation. Keywords             : benign prostatic hyperplasia, prostate specific antigen, prostate volumeCorrespondence   : [email protected]

Abstract Background: Prostate-specific antigen (PSA) is the most reliable tumor marker available and is widely used for the diagnosis and management of prostate cancer. Unfortunately, PSA cannot distinguish efficiently between benign and malignant disease of the prostate, especially within the range of 4–10 μg/L. Among the refinements developed to enhance PSA specificity is the free/total PSA ratio, which is useful in discriminating between the two diseases within the diagnostic “gray zone”. Recent data indicate that human glandular kallikrein (hK2), a protein with high homology to PSA, may be an additional serum marker for the diagnosis and monitoring of prostate cancer. Methods: We analyzed 206 serum samples (all before treatment was initiated) from men with histologically confirmed benign prostatic hyperplasia (n = 100) or prostatic carcinoma (n = 106) with total PSA in the range of 2.5–10 μg/L. Total and free PSA and hK2 were measured with noncompetitive immunological procedures. Statistical analysis was performed to investigate the potential utility of the various markers or their combinations in discriminating between benign prostatic hyperplasia and prostatic carcinoma. Results: hK2 concentrations were not statistically different between the two groups of patients. There was a strong positive correlation between hK2 and free PSA in the whole patient population. hK2/free PSA ratio (area under the curve = 0.69) was stronger predictor of prostate cancer than the free/total PSA ratio (area under the curve = 0.64). At 95% specificity, the hK2/free PSA ratio identified 30% of patients with total PSA between 2.5–10 μg/L who had cancer. At 95% specificity, the hK2/free PSA ratio identified 25% of patients with total PSA between 2.5 and 4.5 μg/L who had cancer. Conclusions: Our data suggest that hK2 in combination with free and total PSA can enhance the biochemical detection of prostate cancer in patients with moderately increased total PSA concentrations. More specifically, the hK2/free PSA ratio appears to be valuable in identifying a subset of patients with total PSA between 2.5 and 4.5 μg/L who have high probability of cancer and who should be considered for biopsy.
