hypericum and Prostatic-Neoplasms

Traditional medicine is very popular in Africa and it is considered as an alternative form of health care. Plants and vegetables used in folk and traditional medicine have gained wide acceptance as one of the main sources of prophylactic and chemopreventive drug discovery and this is due to the evidence of particular biological and biochemical characteristics of each plants extracts. The role of these compounds in urological field may be explained by the antiinflammatory effect through interference with prostaglandin metabolism, alteration of lipid peroxidation, direct inhibition of prostate growth and moreover through an antiandrogenic or antiestrogenic effect and a decrease of the availability of sex hormone-binding globulin. Since Benign Prostatic Hyperplasia and Prostate Cancer are two of the most diffuse diseases of aging male and considering that standard medical therapy is accompanied with different side effects, the emerging use of African plants may be justified. This review takes a look at some African plants extracts properties and their relative urological application. Different biomolecular mechanisms of action are promising, suggesting a real application in reducing prostate cells proliferation.

This article reviews complementary and alternative therapies for advanced prostate cancer. This is not a comprehensive survey of nontraditional therapies for prostate cancer. Rather, this review focuses on alternative and complementary therapies with published studies to evaluate efficacy and safety. Three areas are addressed: alternative forms of hormonal therapy, management of side effects of hormonal therapy, and management of skeletal complications.

Prostate cancer (PCa) is the most frequent type of cancer in men. Hypericum perforatum (H. Perforatum) extract (HPE) administration provides remarkable decrease of PCa development. H. perforatum contains 7 conserved miRNAs (Hyp-miR-156a, Hyp-miR-156b, Hyp-miR-166, Hyp-miR-390, Hyp-miR-394, Hyp-miR-396 and Hyp-miR-414) with different targets. In this study, we aimed to investigate cross-kingdom gene regulation via miRNAs of H. perforatum flower dietetically absorbed in manner of an in silico approach to define potential biomarkers for PCa. psRNATarget database was used to find human genes targeted by 7 pre-defined H. perforatum miRNAs. We defined the mostly affected gene families from these miRNAs as ZNF, TMEM, SLC and FAM gene families. GeneMANIA database was used to define the most affected genes (TMEM41B and SLC4A7) from these 7 miRNAs. cBioPortal database was used to define alteration frequencies of TMEM41B and SLC4A7 on different types of PCa and to measure the mutual interaction potency and significance of co-occurence in PCa. This analysis showed that neuroendocrine prostate cancer (NEPC) had the highest total mutation frequency (22%) of TMEM41B and SLC4A7 genes. Also, TMEM41B and SLC4A7 genes had an average 2.1% pathway change potential among all different types of PCa. Moreover, TMEM41B and SLC4A7 gene pair was found significantly co-occurrent in PCa (p < 0.001). Finally, via GEPIA database, we used Spearman correlation analysis to measure the correlation degree of TMEM41B and SLC4A7 genes in PCa and found their significant correlation with PCa (p = 1.2 × 10

The antiproliferative effect of serotonin-reuptake inhibitors (SSRI) and serotonin antagonists has been demonstrated in prostate tumors. Since Hypericum perforatum components act as serotonin-reuptake inhibitors and exert cytotoxic effects on several human cancer cell lines, in this work we analyzed the effect of a treatment with Hypericum perforatum extract (HPE) on the growth of human prostate cancer cells in vitro and in vivo. This study highlighted a significant reduction of tumor growth and number of metastasis suggesting that this natural compound may be useful in the treatment of prostate cancer.
