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...

Mutational inactivation of p53 is a key player in the development of human cancer. Thus, retrieving the tumor suppressor activity of p53 gene is considered a novel strategy in cancer therapy. Current study aimed to investigate the anti-cancer potentials of botulinum toxin type-A (BTX-A) and captopril as a trial to shed light on effective anti-cancer therapy with lower side effects. Cytotoxic ef...

Growing genetic and molecular biological evidence suggests that the disruption of balance between Secreted Frizzled-Related Protein-1 (SFRP1) and β-catenin plays an important role in the initiation and development of multiple cancers. The aim of this study was to examine whether the expression of SFRP1 and β-catenin is associated with the clinical-pathologic features of patients with prostate c...

This study is to construct a lentiviral vector harbouring an RNA interference (RNAi) sequence that targets the gene encoding the human high-mobility group nucleosomal binding protein 1 (NSBP1); to study its role in inducing G(2)/M phase arrest and apoptosis in prostate cancer (PCa) DU145 cells; and to assess the effect of its knockdown on cell proliferation in vitro and in vivo. RNAi was applie...

Of six prostatic carcinoma cell lines examined (ALVA31, DU145, JCA1, LNCaP, ND1, and PC3) by flow cytometric analysis, all were found to be positive for Fas antigen. Furthermore, of the prostate tissue specimens studied (six cases), all revealed Fas expression in benign and malignant epithelial cells. The agonistic anti-Fas monoclonal antibody (IPO-4) induced apoptosis in only two of six cell l...
