大鼠腹侧前列腺中受氟他胺调控的新基因:去势和氟他胺处理对其表达的调控
Aim: To identify flutamide regulated genes in the rat ventral prostate. Methods: Total RNA from ventral prostates of control and flutamide treated rats were isolated. Differentially expressed transcripts were identified using differential display reverse transcriptase polymerase chain reaction. The effect of castration on the expression of flutamideregulated transcripts was studied. Results: We have identified β2-microglobulin, cytoplasmic FMR1 interacting protein 2 and pumilio 1 as flutamide induced and spermine binding protein and ribophorin Ⅱ as flutamide repressed targets in the rat ventral prostate. Although flutamide treatment caused an induction of pumilio 1 mRNA, castration had no effect. Conclusion: Castration and flutamide treatments exert differential effects on gene expression. Flutamide might also have direct AR independent effects, which might have implications in the emergence of androgen independent prostate cancer and the failure of flutamide therapy.
