X‐box binding protein‐1 (XBP‐1) is an important regulator of a subset of genes active during endoplasmic reticulum (ER) stress. In the present study, we analyzed XBP‐1 level and location to explore the effect of ER stress on oocyte maturation and developmental competency of porcine embryos in an in vitro culture system. First, we examined the localization of XBP‐1 at different meiotic stages of porcine oocytes and at early stages of parthenogenetic embryo development. Fluorescence staining showed that expression of functional XBP‐1 was weak in mature oocytes and at the one‐cell, two‐cell, and eight‐cell stages of embryos, but abundant at the GV oocyte, four‐cell, morula, and blastocyst stages. In addition, RT‐PCR revealed that both spliced XBP‐1 (XBP‐1s ) and unspliced XBP‐1 (XBP‐1u) were expressed at the GV oocyte, four‐cell, morula, and blastocyst stages. Tunicamycin (TM), an ER stress inducer, blocked porcine embryonic development at the four‐cell stage, exhibiting the effect on embryonic genome activation. Next, porcine embryos cultured in the presence of tauroursodeoxycholate (TUDCA), an ER stress inhibitor, were studied. Total cell numbers and the extent of the ICM increased (p<0.05), whereas the rate of nuclear apoptosis decreased (p<0.05). Moreover, expression of the anti‐apoptotic gene Bcl‐2 increased whereas expression of the pro‐apoptotic genes Bcl‐xl and p53 decreased. The results indicated that inhibition of ER stress enhanced porcine oocyte maturation and embryonic development by preventing ER stress‐mediated apoptosis in vitro.
