title: Rat PSP94 inhibits the growth and viability of the rat adenocarcinoma cell line PAIII in vitro.
abstract: Previous studies have shown that human PSP94 can inhibit the growth of prostate cancer cells both in vitro and in vivo. To further validate this potential and investigate the protein within a homologous setting, we examined the effects of rat PSP94 on the growth of the rat prostate adenocarcinoma cell line PAIII in vitro. To generate rat PSP94, we used both a plasmid-based expression system and a recombinant rat PSP molecule. Rat PSP was shown to inhibit the growth and survival of PAIII cells in a dose-dependent manner with > 90 percent reductions in both observed. TUNEL and Annexin-V assays confirmed PAIII cell death to be via apoptosis.
