Abstract
BACKGROUND Prostate cancer is the second most common cause of cancer death worldwide in men. The development of novel and highly efficient therapeutic strategies is strongly recommended to treat prostate cancer. Cyperaceae are an ecologically and economically important family of plants with several pharmacological effects. However, the biological efficacy of Cyperus exaltatus var. iwasakii (CE) is unknown. PURPOSE This study aimed to investigate the antitumor effect of the ethanol extract of CE against prostate cancer. METHODS In vitro antitumor efficacy of CE was explored by the MTT assay, cell counting assay, FACS analysis, immunoblot, wound-healing migration, invasion assay, zymographic assay, and EMSA in prostate cancer cells, DU145 and LNCaP. For in vivo experiments, xenograft mice were injected with LNCaP cells. Histology (H&E and Ki-67) and biochemical enzyme assay were then performed. The toxicity test was evaluated by an acute toxicity assay. The phytochemical constituents of CE were identified by spectrometric and chromatographic analyses. RESULTS CE exerted a significant antiproliferative effect against prostate cancer cells. CE-induced antiproliferative cells were associated with cell cycle arrest at G0/G1 (cyclin D1/CDK4, cyclin E/CDK2, p21Waf1) in DU145 cells, but G2/M (ATR, CHK1, Cdc2, Cdc25c, p21Waf1, and p53) in LNCaP cells. CE stimulated the phosphorylation of ERK1/2, p38 MAPK, and AKT in DU145 cells, but only p38 MAPK phosphorylation was increased in LNCaP cells. CE treatment suppressed migration and invasion in the two types of prostate cancer cells by inhibiting MMP-9 activity through the regulation of transcription factors, such as AP-1 and NF-κB. In vivo experiments showed a reduction in tumor weight and size following oral CE administration. Histochemistry confirmed that CE inhibited tumor growth in the mouse LNCaP xenograft model. The administration of CE had no adverse effects on body weight, behavioral patterns, blood biochemistry, and histopathology findings of vital organs in mice. Finally, a total of 13 phytochemical constituents were identified and quantified in CE. The most abundant secondary metabolites in CE were astragalin, tricin, and p-coumaric acid. CONCLUSION Our results demonstrated the antitumor efficacy of CE against prostate cancer. These findings suggest that CE might be a potential candidate for prostate cancer prevention or treatment.

Himachalol induces apoptosis in B16-F10 murine melanoma cells and protects against skin carcinogenesis. JOURNAL OF ETHNOPHARMACOLOGY 2020; 253:112545. [PMID: 31918014 DOI: 10.1016/j.jep.2020.112545] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/02/2019] [Revised: 12/30/2019] [Accepted: 01/01/2020] [Indexed: 06/10/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Cedrus libani A. Rich (C. libani) is majestic evergreen Mediterranean conifer growing in the mountains of Lebanon. The ethnobotanical and traditional uses of cedar wood oil traces back to ancient times for the treatment of various ailments including cancer. Previous work in our laboratories revealed that himachalol (7-HC), a major sesquiterpene isolated from C. libani, possesses potent cytotoxic activity against various human cancer cell lines as well as promising anti-inflammatory effect in isolated rat monocytes. AIM OF THE STUDY The present study aims to elucidate the mechanism of action behind the cytotoxic activity of 7-HC against murine melanoma cells (B16F-10) and evaluates its chemopreventive effect against chemically-induced skin carcinogenesis in mice. MATERIALS AND METHODS 7-HC was extracted and purified from Cedrus libani wood. Cell viability was evaluated using WST-1 kit. Cell cycle analysis and apoptosis were assessed by Flow cytometry using propidium iodide (PI) and fluorescein Isothiocyanate (FITC)-conjugated Annexin V/PI staining respectively. Apoptosis related protein were quantified using western blot. The chemopreventive activity of 7-HC was evaluated for 20 weeks using a DMBA/TPA induced skin carcinogenesis model in Balb/c mice. RESULTS 7-HC displayed a potent anti-proliferative activity against the melanoma cells with an IC50 of 8.8 μg/ml and 7.3 μg/ml at 24 and 48 h, respectively. Co-treatment with Cisplatin did not show any synergistic or additive effect on cell viability. Flow cytometry analysis using PI revealed that 7-HC treatment (5 and 10 μg/ml) induces the accumulation of cells in the sub-G1 phase and causes a decline in cell populations in the S and G2/M phases. Annexin/PI staining also reveals that 7-HC treatment significantly increases the percentage of cells undergoing early and late apoptosis. Western blot analysis shows that 7-HC treatment decreases the level of the anti-apoptotic protein Bcl-2 and increases the level of the pro-apoptotic protein Bax. A reduction in the level of phosphorylated Erk and Akt was also observed. 7-HC via topical (2.5%), intraperitoneal (10, 25 and 50 mg/kg) or gavage (50 mg/kg) treatment revealed a significant decrease in papilloma volume with no adverse effect on liver and kidney function. CONCLUSIONS The present study demonstrates that 7-HC treatment protects against chemically-induced skin carcinogenesis, promotes cell cycle arrest and induces apoptosis partially through an inhibition of both the MAPK/Erk and PI3K/Akt pathways.

Abstract
Prostate cancer is a heterogeneous disease, the second deadliest malignancy in men and the most commonly diagnosed cancer among men. Traditional plants have been applied to handle various diseases and to develop new drugs. Medicinal plants are potential sources of natural bioactive compounds that include alkaloids, phenolic compounds, terpenes, and steroids. Many of these naturally-occurring bioactive constituents possess promising chemopreventive properties. In this sense, the aim of the present review is to provide a detailed overview of the role of plant-derived phytochemicals in prostate cancers, including the contribution of plant extracts and its corresponding isolated compounds.

Abstract
BACKGROUND Even though several specialist groups, including the German Pension Insurance (Deutsche Rentenversicherung) and health insurance funds, participate in the rehabilitation of patients with prostate carcinoma, there is no standardized rehabilitation program available for these patients. Consequently, there is no transparency regarding the services provided within the scope of rehabilitation for the referring physicians to uro-oncological rehabilitation, in particular, neither for physicians at urological acute-care clinics, nor for the patients concerned. Rehabilitation clinics are rather left to their own devices as to which services they provide in the treatment of the respective disease and in social situations, but also with regard to the consulting services offered. PROBLEM Development of a standard for the rehabilitation of patients with prostate carcinoma, taking into account both specialist circles and self-help groups relevant to this matter. METHODS Specialist groups, including self-help groups participating in the rehabilitation of patients with prostate cancer, have formed an expert group and developed the present standard. To this end, a thematic unsystematic literature review was carried out in advance to provide an evidence-based foundation. RESULTS Views were given with regard to rehabilitation diagnostics, the therapy of urinary incontinence and erectile dysfunction, sport and physical exercise therapy, psycho-oncology, and social- and disease-related consulting. In this context, the focus was set on classification as well as on the consensus strength of the respective recommendations. CONCLUSION All parties involved in the rehabilitation of prostate cancer patients, as well as the patients and the responsible cost bearers, can now use the standard as an orientation guide.

Abstract
Prostate cancer continues to represent a burgeoning medical problem in the United States. Recent studies suggest that gossypol, a bioactive phytochemical produced by cotton plants, is a promising agent against prostate cancer. The current studies were undertaken to examine the chemotherapeutic efficacy of gossypol on human prostate cancer cell lines and prostate tumor-initiating cells. Gossypol reduced the viability of three prostate cancer cell lines (LAPC4, PC3, and DU145) with an IC(50) between 3 and 5 micromol/L. Additionally, gossypol was effective at inhibiting prostate tumor-initiating cell-driven tumor growth in a nonobese diabetic/severe combined immunodeficient xenograft model. Our integrated molecular profiling approach encompassing proteomics, activated transcription factors, and genomics suggests that the decrease in viability was associated with increased DNA damage and the induction of apoptosis. Exposure of DU145 cells to gossypol (1-10 micromol/L) resulted in the activation of 13 proteins and 7 transcription factors, and the expression of 17 genes involved in the mitochondrial pathway of apoptosis. These studies show for the first time that gossypol treatment induces DNA damage and activates p53. Collectively, these data support the use of gossypol as a novel agent for prostate cancer.
