The aim of this study was to investigate the effects of plant phenolic compound tannic acid (TA) on proliferative, metastatic, invasive properties of prostate cancer (PCa) cells; PC-3 and LNCaP, as well as drug metabolizing and antioxidant enzymes. Characterization of TA was done by using FT-IR and NMR. TA dose dependently inhibited the proliferation of PC-3 and LNCaP cells with IC50 values 35.3 mu M and 29.1 mu M, respectively. Wound healing assay showed that TA significantly inhibited (92.7%) migration of PCa cells (p<0.0001). In addition, TA was found to have anti-invasive potential on PC-3 cells and it inhibited (80.9%, p<0.0001) invasion of PC-3 cells into matrigel. Only 17.8% of PC-3 cells can form colony in the 0.7% agarose after treatment of cells with TA at the IC50 value concentration. Furthermore, flow cytometry analyses with Annexin V-APC and 7-AAD staining demonstrated that TA increases early apoptosis rate of PC-3 cells by 25.8% and LNCaP cells by 20.9%. Besides, Western blot and qRT-PCR analyses also demonstrated that TA regulates protein and mRNA expressions of CYP17A1, CYP3A4, CYP2B6, NQO1, GSTM1 and GSTP1 enzymes. The results obtained from this study show that TA might be a good candidate for combinational therapy and highly effective strategic molecule for reducing the occurrence of PCa.

Enantiomerically pure beta-dipeptide derivative induces anticancer activity against human hormone-refractory prostate cancer through both PI3K/Akt-dependent and -independent pathways

The use of peptides that target cancer cells and induce anticancer activities through various mechanisms is developing as a potential anticancer strategy. KUD983, an enantiomerically pure beta-dipeptide derivative, displays potent activity against hormone-refractory prostate cancer (HRPC) PC-3 and DU145 cells with submicromolar IC50. KUD983 induced G1 arrest of the cell cycle and subsequent apoptosis associated with down-regulation of several related proteins including cyclin D1, cyclin E and Cdk4, and the ...
Selenium, nickel, and calcium levels in cancerous and non-cancerous prostate tissue samples and their relation with some parameters

In the present study, tissue samples of patients with cancerous and non-cancerous prostate were analyzed for their Se, Ni, and Ca contents. Possible relationship between Se, Ni, and Ca concentrations and some parameters including preoperative prostate-specific antigen (PSA) levels, histopathological neurovascular invasion, extra-capsular extension, seminal vesicle invasion, positive surgical margins, PSA relapse after radical prostatectomy, and total Gleason scores were obtained. Inductively coupled plasma ...
GST isoenzymes in matched normal and neoplastic breast tissue
OĞUZTÜZÜN, SERPİL; Abu-Hijleh, A.; ÇOBAN, TÜLAY; Bulbul, D.; KILIÇ, MURAT; İŞCAN, Mümtaz; İşcan, Mesude (AEPress, s.r.o., 2011-01-01)
The potential to metabolize endogenous and exogenous substances may influence breast cancer development and tumor growth. Therefore we investigated GST activity and the protein expression of glutathione S-transferases (GSTs) isoenzymes known to be involved in the metabolism of endogenous and exogenous carcinogens in breast cancer tissue to obtain new information on their possible role in tumor progression.
Novel triazolothiadiazines act as potent anticancer agents in liver cancer cells through Akt and ASK-1 proteins
Aytac, Peri S.; Durmaz, Irem; Houston, Douglas R.; Atalay, Rengül; TOZKOPARAN KÖPRÜCÜ, BİRSEN (2016-02-15)
Newly designed triazolothiadiazines incorporating with structural motifs of nonsteroidal analgesic anti-inflammatory drugs were synthesized and screened for their bioactivity against epithelial cancer cells. Compounds with bioactivities less then similar to 5 mu M (IC50) were further analyzed and showed to induce apoptotic cell death and SubG(1) cell cycle arrest in liver cancer cells. Among this group, two compounds (1g and 1h) were then studied to identify the mechanism of action. These molecules triggere...
Synthesis of novel 6-substituted amino-9-(beta-D-ribofuranosyl)purine analogs and their bioactivities on human epithelial cancer cells
TUNÇBİLEK, MERAL; Kucukdumlu, Asligul; Guven, Ebru Bilget; Altiparmak, Duygu; Atalay, Rengül (2018-02-01)
New nucleoside derivatives with nitrogen substitution at the C-6 position were prepared and screened initially for their in vitro anticancer bioactivity against human epithelial cancer cells (liver Huh7, colon HCT116, breast MCF7) by the NCI-sulforhodamine B assay. N-6-(4-trifluoromethylphenyl) piperazine analog (27) exhibited promising cytotoxic activity. The compound 27 was more cytotoxic (IC50 = 1-4 mu M) than 5-FU, fludarabine on Huh7, HCT116 and MCF7 cell lines. The most potent nucleosides (11, 13, 16,...
