Effect of Heat Stress on Sperm DNA: Protamine Assessment in Ram Spermatozoa and Testicle

Table 4

Gene expression of PRM1, TNP1, and TNP2 in epididymal ram sperm presented as number of copies considering effect of time (D0 versus D30). Mean ± SEM and value.

Target genes	D0	D30
PRM1 mRNA copies	0.92 ± 0.12	10.74 ± 2.87	<0.0001
TNP1 mRNA copies	2.81 ± 0.61	0.94 ± 0.18	0.12
TNP2 mRNA copies	0.39 ± 0.08	0.72 ± 0.35	0.24
