摘要：We tested whether reductions in spermatozoal quality induced by under-nutrition are associated with increased germ cell apoptosis and disrupted spermatogenesis, and whether these effects are mediated by small RNAs. Groups of 8 male sheep were fed for a 10% increase or 10% decrease in body mass over 65 days. Underfeeding increased the number of apoptotic germ cells (P TP53 , CASP3 , FASL ). The proportion of miRNAs as a total of small RNAs was greater in well-fed males than in underfed males (P
