We report the silencing of CA1 mRNA in PC3 and MDA cells. The levels of mRNA coding CA1 protein in the knock-down mRNA (CA1 siRNA) cells have been measured by RT-PCR and were approximately 5% (PC3) and 20% (MDA-MB-231), respectively, of the level of control (Mock siRNA) used during silencing. In PC3 and MDA-MB-231 cells, the mRNAs for COL1A1 and COL4A4 were up-regulated. The mRNAs for CTHRC1, L...

5(S)-Hydroxy-6,8,11,14-E,Z,Z,Z-eicosatetraenoate (5-HETE) causes PC3 cells to grow by an unknown mechanism. We find that it also induces the cells to activate extracellular signal-regulated kinases and Akt. Pertussis toxin inhibits both responses. 5-HETE, 5-oxo-6,8,11,14-E,Z,Z,Z-eicosatetraenoate, and 5-oxo-15-hydroxy-eicosatetraenoate are known to stimulate leukocytes by a receptor coupled to ...

Liposomal magnetofection is a simple, highly efficient technology for cell transfection, demonstrating better outcome than a number of other common gene delivery methods. However, aggregate complexes distribution over the cell surface is non-uniform due to the gradient of the permanent magnetic field. The aim of this study was to estimate the efficiency of liposomal magnetofection for prostate ...

In the current study, we investigated a combination of docetaxel and thalidomide (DT therapy) in castration-resistant prostate cancer (CRPC) patients. We identified marker genes that predict the effect of DT therapy. Using an androgen-insensitive PC3 cell line, we established a docetaxel-resistant PC-3 cell line (DR-PC3). In DR-PC3 cells, DT therapy stronger inhibited proliferation/viability th...

Prostate cancer is frequent among men over 45 years of age, but it generally only becomes lethal with metastasis. In this study, we identified a gene called cellular stress response 1 (CSR1) that was frequently down-regulated and methylated in prostate cancer samples. Survival analysis indicated that methylation of the CSR1 promoter, and to a lesser extent down-regulation of CSR1 protein expres...

BACKGROUND Kallikreins play a pivotal role in establishing prostate cancer. RESULTS In contrast to the classical Kunitz plant inhibitor SbTI, the recombinant kallikrein inhibitor (rBbKIm) led to prostate cancer cell death, whereas fibroblast viability was not affected. CONCLUSION rBbKIm shows selective cytotoxic effect and angiogenesis inhibition against prostate cancer cells. SIGNIFICANC...

PURPOSE Thalidomide has demonstrated clinical activity in various malignancies including androgen-independent prostate cancer. The development of novel thalidomide analogs with better activity/toxicity profiles is an ongoing research effort. Our laboratory previously reported the in vitro antiangiogenic activity of the N-substituted thalidomide analog CPS11 and the tetrafluorinated analogs CPS4...

Prostate cancer (PCa) is a leading cause of death among males. It is currently estimated that inflammatory responses are linked to 15-20% of all deaths from cancer worldwide. PCa is dominated by complications arising from metastasis to the bone where the tumor cells interact with the bone microenvironment impairing the balance between bone formation and degradation. However, the molecular natur...

We have characterized glycoprotein H (GpH) from bovine adrenal medullary chromaffin granules. Two-dimensional gel electrophoresis was used to purify GpH from an insoluble fraction obtained following extraction of chromaffin granule membranes with lithium diiodosalicylate. The GpH material was recovered from two-dimensional gel spots by concentration and recovery on a one-dimensional gel followe...
