ABSTRACT

SUMMARY:

Spermatogenesis is a major process in testis occurring from puberty through life span of males. The tyrosine phosphorylation is assumed to play roles in spermatogenesis because this process is important for cell proliferations, divisions, and differentiations. However, the localizations and identifications of phosphorylated proteins in testicular tissue of adult male rats are still unclear. Therefore, this study attempted to immuno-localize and identify such proteins in testicular tissues of Sprague-Dawley rats. The monoclonal anti-phosphotyrosine (clone 4G10) was used to probe tyrosine phosphorylated proteins and also to examine the expression of such proteins using immuno-Western blotting in rat testis. The result showed that positive reactivity of tyrosine phosphorylated proteins was clearly observed in interstitial endocrine cells (Leydig cells), sustentocytes (Sertoli cells), spermatogonia, spermatocytes, and spermatids (round and elongated), respectively. The expressions of testicular tyrosine phosphorylated proteins were 200, 131, 93, 70, 60, and 48 kDas, respectively. In conclusion, testicular tyrosine phosphorylated proteins were localized in both germinal epithelium and interstitial endocrine cells of adult Sprague-Dawley rats.
RESUMEN
RESUMEN La espermatogénesis es un proceso importante en los testículos que ocurre desde la pubertad a lo largo de la vida de los machos. Se supone que la fosforilación de la tirosina desempeña papeles en la espermatogénesis, debido a que este proceso es importante para las proliferaciones, divisiones y diferenciaciones celulares. Sin embargo, las localizaciones e identificaciones de proteínas fosforiladas en el tejido testicular de ratas macho adultas todavía no están claras. Por lo tanto, este estudio intentó inmuno-localizar e identificar dichas proteínas en tejidos testiculares de ratas Sprague-Dawley. La anti-fosfotirosina monoclonal (clon 4G10) se usó para sondar proteínas tirosina fosforiladas y también para examinar la expresión de tales proteínas usando inmunotransferencia Western en testículo de rata. El resultado mostró que la actividad positiva de las proteínas tirosina fosforiladas se observó claramente en endocrinocitos intersticiales (células de Leydig), sustentocitos (células de Sertoli), espermatogonias, espermatocitos y espermátidas (redondas y alargadas), respectivamente. Las expresiones de las proteínas tirosina fosforiladas testiculares fueron de 200, 131, 93, 70, 60 y 48 kDas, respectivamente. En conclusión, las proteínas tirosina fosforiladas fueron localizadas en ambos epitelios germinales y endocrinocitos intersticiales de ratas adultas Sprague-Dawley.
