Quantification of mRNA levels for (a) Bax (b) Caspase-3 (c) Bip (d) PSMB5 proteasome subunit β5 and (e) HSP70 by real-time RT-PCR in bovine blastocysts produced either <i>in vitro</i> (IVF or SCNT) or <i>in vivo</i>.

<p>(f) Table of mRNA expression levels presented as fold change relative to control embryos. Normalized transcription levels are shown as mean ± standard error of the mean (SEM). Different superscripts indicate statistical differences between treatment groups (<i>P</i><0.05). Data were obtained from three replicates of independent groups of 10 embryos each.</p
