A series of novel arylpiperazine derivatives was synthesized. The in vitro cytotoxic activities of all synthesized compounds against three human prostate cancer cell lines (PC-3, LNCaP, and DU145) were evaluated by a CCK-8 assay. Compounds 9 and 15 exhibited strong cytotoxic activities against LNCaP cells (IC50<5 μM), and compound 8 (IC50=8.25 μM) possessed the most potent activity against DU14...

The possible roles of STEAP4 in cancer progression have not been reported. In this study, we report that STEAP4 expression is able to inhibit anchorage-independent cell growth. We also demonstrate that STEAP4 associates with focal adhesion kinase (FAK) and regulate the activity of FAK through Y397 phosphorylation. Furthermore, we show that CpG sequences in STEAP4 promoter region were frequently...

Introduction. By a microarray approach, using the experimental model of Nerve Growth Factor (NGF)-induced reduction of DU145 prostate cancer (PCa) cell line malignancy (1, 2), we identified the non-metastatic glycoprotein melanoma protein B (GPNMB) gene, encoding a type 1 transmembrane 572 amino acid protein (3). GPNMB, also known as osteoactivin (OA), is expressed in a wide array of normal and...

The expression of 119 cell surface molecules was catalogued for three prostate cancer cell lines, LNCaP, PC3, and DU145, all of which were established from metastases. Many of these molecules are common to all three cell lines, whereas some are differentially expressed. More prostate basal epithelial cell-specific than luminal epithelial cell-specific molecules are detected, especially in DU145...

A complementary DNA clone containing human endogenous retrovirus-like sequences spliced to sequences encoding human calbindin was discovered by complementary DNA subtraction analysis between two human prostate cell lines, PC3 and DU145. This gene is presumably activated by the long terminal repeat of the retrovirus-like sequence. It belongs to a member of the retrovirus-like H (tRNA(his) primer...

A new diketopiperazine, glionitrin B (1), was produced using a microbial coculture of the fungus Aspergillus fumigatus KMC-901 and the bacterium Sphingomonas sp. KMK-001 that were isolated from acidic coal mine drainage. The structure of 1 was determined to be (3S,10aS)-dithiomethylglionitrin A. This structure was determined by the analyses of extensive NMR data and the circular dichroism spect...
