The antiandrogen flutamide was injected (10 mg/Kg b.w.) to adult male mice which were sacrificed 24h. and 72h. after. Controls injected with the vehicle (corn oil) were sacrificed at the same intervals. Cryosections were made of the epididymides and examined by the TUNEL method for quantification of apoptosis and also using immunocytochemistry to visualize the expression of the stress protein HSP70. The highest indexes of apoptosis were observed in the caput epididymis after 72 h. and were of 7.40 cells/1000 in contrast to controls (0.21 cells/1000). HSP70 appeared particularly increased in the caput and cauda epididymis after 72 h. treatment. Results indicated that the blockage of androgen receptors induces apoptosis and a HSP70 expression in the principal epithelial cells of the mouse epididymis, and that these changes occur in a region-specific fashion.[ES]Este trabajo estudia los cambios inducidos por el bloqueador de receptores de andrógeno flutamida en el epitelio del epidídimo del ratón. Varios machos adultos fueron inyectados con flutamida (lOmg/Kg.b.w.) y se sacrificaron a las 24 y 72horas. Otros machos, que sirvieron de controles fueron inyectados sólo con el vehículo empleado para las inyecciones (aceite de maíz) y se sacrificaron a intervalos similares. Los epidídimos tratados y controles fueron examinados mediante el método TÚNEL para cuantificar la apoptosis y mediante procedimientos inmunocitoquímicos para localizar la proteína de stress HSP70. El índice apoptótico más alto fue observado en la cabeza del epidídimo después de 72 horas de tratamiento. HSP70 se observó también a las 72 horas en la cabeza y en la cauda epididimaria. Los resultados indican que el bloqueo de los receptores de andrógenos induce apoptosis y expresión de HSP70 en las células principales del epitelio epididimario, y que estos cambios ocurren afectando a regiones específicas del epidídimo.This work was partially supported by grant BCM2003-00211 from DGICYT (Spain).Peer reviewedSociedad Chilena de AnatomíaDirección General de Investigación Científica y Técnica, DGICT (España)Consejo Superior de Investigaciones Científicas [https://ror.org/02gfc7t72]202120212009info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501Publisher's versioninfo:eu-repo/semantics/publishedVersionhttp://hdl.handle.net/10261/245043reponame:DIGITAL.CSIC.
