Methods and results; cDNA of ratcaspase-1 was cloned by reverse transcription-polymerase chain reaction from the ventral prostates. The open readingframe predicts 402 amino acids, which shows more than 91% and 63% identity to those of mouse and human, respec-tively. Northern analyses demonstrated the presence of castration-induced up-regulation of the 1.6 kb transcript in theventral prostate and the seminal vesicles. Finally, the authors demonstrated the caspase-1 transcripts in the epithelia ofthese tissues by in situ hybridization analyses. Conclusion; Castration induces the expression of caspase-1 tran-scripts in the epithelia of ventral prostate and seminal vesicle. These observations suggest a possible role of caspase-1 inapoptosis in male accessory sex organs.展开更多
