Dynamics of HSPA1A and redox status in the spermatozoa and fluid from different segments of goat epididymis.

The present study was attempted to investigate the dynamics of HSPA1A and redox status in the spermatozoa and fluid of different segments of buck epididymis. Testes were collected from sexually mature and healthy bucks aged between 2 and 3 years. The fluid and spermatozoa from different segments (caput, corpus and cauda) were harvested for further processing and analysis.

Effect of sericin supplementation on heat shock protein 70 (HSP70) expression, redox status and post thaw semen quality in goat.

Cryopreservation results in substantial deterioration of heat shock protein 70 (HSP70) and ultra-structural changes in sperm organelles, resulting in a marked reduction in post-thaw semen quality. The present study was aimed to explicate the effect of sericin supplementation on expression profile of HSP70, redox status and post-thaw semen quality in Barbari goat. Five Barbari bucks were used to collect thirty semen ejaculates by using artificial vagina and each ejaculate was divided into three aliquots to which sericin was supplemented at 0% (Control), 0.
