Paclitaxel, which isolated from Taxus brevifolia, is recently started to be used against prostate cancer treatment and it is a very effective compound against cancer. In this study, we aimed to test the synergistic effect of two plant active compounds (sulphoraphane (SFN) and silymarin (SILY)) and several endemic plant species from Turkey (such as Phlomis leucophracta, Rubia davisiana, Alkanna tinctoria), which are known to have anticarcinogenic effect on androgen-independent PC3 and DU145, and androgen-dependent VCaP prostate cancer cell lines, with paclitaxel on the expression of cell cycle signaling and apoptosis regulator genes...

The morbidity and mortality of prostate cancer (PCa) in China have increased obviously, which became the second leading cause of death in men with cancer. Hedgehog (Hh) signaling pathway is a key signaling pathway involved in the prostate cancer progression. The human oncogene SCL/TAL1 interrupting locus (STIL) can modulate the Hh signaling pathway, but its function in PCa has not been reported. Here, we showed that STIL was increased in high grade prostate cancer tissue. Knockdown of STIL in prostate cancer cells PC-3 and DU 145 significantly decreased the proliferation of cells and induced cellular apoptosis through casepase3/7 mediated pathway...

The dosage of prostate specific antigen (PSA), an easily evaluable and non-invasive biomarker, has made early detection of prostate cancer (PCa) possible. However, it leads to high percentages of unnecessary biopsies and may miss aggressive tumors in men with PSA levels below 4 ng/ml. Therefore, we propose to combine circulating microRNAs with PSA, to improve the diagnostic route for PCa.Plasma microRNA profiling identified candidate diagnostic microRNAs in a discovery cohort of 60 tumors and 60 controls (men with benign prostatic hyperplasia or healthy donors)...

In this work, we have developed a reducible, self-assembling disulfide cross-linked and peptide-based micelle system for co-delivery of miR-4638-5p and DTX to improve the efficacy of castration-resistant prostate cancer (CRPC) therapy. The result showed that DTX in micelles (DTX-VPs) inhibited cell growth and induced apoptosis more effectively than free DTX both in vitro and in vivo. In addition, the DTX and miR-4638-5p loaded micelles (Co-VPs) achieved the most pronounced anticancer effect of all groups. Immunohistochemical analysis indicated that miR-4638-5p in micelle system could effectively downregulate the expression of Kidins220 and further improve the anticancer effect by enhancing tumor cell apoptosis and suppressing tumor cell proliferation...

To enhance the structural diversity of isoflavonoids and provide more derivatives for the biological screening, a semisynthetic mixture was generated by diversification of the crude extract of Radix puerariae through the chemical reaction with hydrazine hydrate. Thirteen derivatives (1-13) were isolated from the semisynthetic mixture, and all those structures were identified by spectroscopic methods in combination with X-ray crystallographic analysis, including eleven 3,4-diarylpyrazoles (1-11) and two 5-phenyl-6-benzyldihy-dropyridazinones (12 and 13)...

From the mid-20th century, accumulating evidence has supported the introduction of screening for cancers of the cervix, breast, colon and rectum, prostate (via shared decisions), and lung. The opportunity to detect and treat precursor lesions and invasive disease at a more favorable stage has contributed substantially to reduced incidence, morbidity, and mortality. However, as new discoveries portend advancements in technology and risk-based screening, we fail to fulfill the greatest potential of the existing technology, in terms of both full access among the target population and the delivery of state-of-the art care at each crucial step in the cascade of events that characterize successful cancer screening...

Prostate cancer (PCa) is a life-threatening disease affecting millions of men. The current best PCa biomarker (level of prostate-specific antigen in serum) lacks specificity for PCa diagnostics and this is why novel PCa biomarkers in addition to the conventional ones based on biomolecules such as DNA, RNA and proteins need to be identified. Areas covered: This review details the potential of glycans-based biomarkers to become diagnostic, prognostic, predictive and therapeutic PCa biomarkers with a brief description of the innovative approaches applied to glycan analysis to date...

Recently, the influence that metabolic syndrome (MetS), hormonal alterations and inflammation might have on prostate cancer (PCa) risk has been a subject of controversial debate. Herein, we aimed to investigate the association between MetS-components, C-reactive protein (CRP) and testosterone levels, and the risk of clinically significant PCa (Sig-PCa) at the time of prostate biopsy. For that, men scheduled for transrectal ultrasound guided biopsy of the prostate were studied. Clinical, laboratory parameters and criteria for MetS characterization just before the biopsy were collected...
