In the present study, the aim was to investigate the role of microRNA-1180 (miR-1180) in the growth and apoptosis of prostate cancer, as well as to identify its direct targets. Initially, reverse transcription-quantitative polymerase chain reaction (RT-qPCR) was performed to examine the expression of miR-1180 in the prostate cancer tissues and adjacent normal prostate tissues of 30 patients, as...

The antiparasitic drug, suramin, has antiproliferative effects in human carcinoma cells. It has been suggested that this occurs through blockade of growth factor-receptor interactions. Three types of evidence that suramin rapidly inhibits cellular respiration or disrupts cellular energy balance in intact cells of the human prostate carcinoma cell line, DU145, are presented. Beginning at approxi...

Prostate cancer can progress from androgen dependence to androgen deprivation resistance with some unknown mechanisms. The current study aims to explore the possible role of pituitary tumor transforming gene1 (PTTG1) in castration-resistant prostate cancer (CRPC). Initially, we found that PTTG1 expression was significantly increased in androgen-independent prostate cancer cell lines PC3, DU145 ...

We isolated a coumarin compound decursin (C(19)H(20)O(5); molecular weight 328) from Korean angelica (Angelica gigas) root and characterized it by spectroscopy. Here, for the first time, we observed that decursin (25-100 micromol/L) treatment for 24 to 96 hours strongly inhibits growth and induces death in human prostate carcinoma DU145, PC-3, and LNCaP cells. Furthermore, we observed that decu...

A validated method has been developed for the simultaneous measurement of reduced and oxidized glutathione in de-proteinised cellular extracts. This has been used to compare models of malignant and non-malignant human prostate cell lines. Analysis of LNCaP and DU145 cells showed a glutathione to glutathione disulfide ratio of 8:1 and 32:1 respectively, whilst the control cell line, PZ-HPV7 disp...

Human tissue kallikrein 7 (hK7), a chymotrypsin-like secreted serine protease, catalyzes the degradation of intercellular adhesive structures in the cornified layer of the skin, leading to desquamation. Thus, hK7 is implicated in cancer invasion and metastasis. Although hK7 is highly expressed in prostate tissues, its biological role in prostate cancer progression is poorly understood. In the c...

Hepatocyte growth factor (HGF) is a glycoprotein that induces prostate cancer cell proliferation, migration and invasion. The activation of transient receptor potential canonical 6 (TRPC6) channels is considered important in promoting prostate cancer cell proliferation. In this study, we assessed the role of endogenous TRPC6 channels in the HGF-induced cell proliferation of prostate cancer. Rev...

Prostate carcinoma (CaP) is a leading cause of cancer-related death in men. We have previously determined the microRNA (miRNA) profile of primary CaP in comparison with nontumor prostate tissue. miRNAs are small, noncoding RNAs that inhibit protein synthesis on a posttranscriptional level by binding to the 30-untranslated region (30-UTR) of their target genes. In primary CaP tissue, we have pre...

Prostate cancer is the second leading cause of morbidity and mortality in males in the Western world. In the present study, LNCaP, which is an androgen receptor-positive and androgen-responsive prostate cancer cell line derived from lymph node metastasis, and DU145, which is an androgen receptor-negative prostate cancer cell line derived from brain metastasis, were investigated. TNFα treatment ...

MKT-077 (formerly known as FJ-776) is a newly synthesized, highly water-soluble ( > 200 mg/ml) rhodacyanine dye that exhibits significant antitumor activity in a variety of model systems. In culture, MKT-077 inhibits the growth of five human cancer cell lines (colon carcinoma CX-1, breast carcinoma MCF-7, pancreatic carcinoma (CRL 1420, bladder transitional cell carcinoma EJ, and melanoma LOX) ...
