ABSTRACT
Methotrexate (MTX) is commonly used as a chemotherapy agent and immune system suppressant but its adverse effect on male reproductive system is still limited. This study aimed to investigate the effect of MTX on structure and functional proteins of testis and seminal vesicle. Adult male rats were divided into control and MTX groups (n =12). In 30 experimental days, the treated animals were injected with MTX (tail i.v., 75 mg/KgBW) at days 8 and 15. Then, the reproductive parameters and histology of both groups were examined. Thickness of seminal seminal vesicle epithelia was analyzed. Also, the expressions of testicular tyrosine phosphorylated proteins and steroidogenic acute regulatory (StAR) protein were investigated. The results showed that MTX could significantly decrease epididymal sperm concentration. In addition, the germ cell degeneration, increased spaces of interstitial tissues, and low epididymal sperm mass density were observed in MTX group. The thickness of seminal vesicle epithelia in MTX group was significantly lower than that of control group. Moreover, the intensity of testicular phosphorylated proteins of 31, 32, 72, and 85 kDas was significantly increased while of 42 and 47 kDas in MTX group was decreased as compared to control. The expression of testicular StAR protein in MTX group was also significantly decreased as compared to the control. In conclusion, MTX affects testicular and seminal tissues and changes testicular functional proteins in adult rats.
RESUMEN
El metotrexato (MTX) se usa comúnmente como agente de quimioterapia y supresor del sistema inmunitario, pero su efecto adverso en el sistema reproductor masculino sigue siendo limitado. Este estudio tuvo como objetivo investigar el efecto del MTX sobre la estructura y las proteínas funcionales del testículo y la vesícula seminal. Ratas macho adultas se dividieron en grupos control y grupo con MTX (n = 12). En 30 días experimentales, a los animales tratados se les inyectó MTX (cola i.v., 75 mg / KgBW) los días 8 y 15. Luego, se examinaron los parámetros reproductivos y la histología de ambos grupos. Se analizó el espesor del epitelio de la vesícula seminal. Además, se investigaron las expresiones de la proteína tirosina testicular fosforilada y de la proteína reguladora aguda esteroidogénica (StAR). Los resultados mostraron que el MTX podría disminuir significativamente la concentración de espermatozoides epididimarios. Además, se observó la degeneración de las células germinales, el aumento de los espacios de los tejidos intersticiales y la baja densidad de masa del espermatozoide epididimal en el grupo de MTX. El grosor del epitelio de la vesícula seminal en el grupo MTX fue significativamente menor que el del grupo control. Además, la intensidad de las proteínas testiculares fosforiladas de 31, 32, 72 y 85 kDas aumentó significativamente, mientras que la de 42 y 47 kDas en el grupo MTX disminuyó en comparación con el control. La expresión de la proteína StAR testicular en el grupo MTX también se redujo significativamente en comparación con el control. En conclusión, el MTX afecta los tejidos testiculares y seminales y cambia las proteínas funcionales testiculares en ratas adultas.
