Abstract
Baicalin, a traditional Chinese medicinal monomer whose chemical structure is known, can be used to treat female infertility. However, the effect of baicalin on embryonic development is unknown. This study investigated the effects of baicalin on in vitro development of parthenogenetically activated (PA) and in vitro fertilized (IVF) pig embryos and the underlying mechanisms involved. Treatment with 0.1 μg/ml baicalin significantly improved (P < 0.05) the in vitro developmental capacity of PA pig embryos by reducing the reactive oxygen species (ROS) levels and apoptosis and increasing the mitochondrial membrane potential (ΔΨm) and ATP level. mRNA and protein expression of sonic hedgehog (SHH) and GLI1, which are related to the SHH signaling pathway, in PA pig embryos at the 2-cell stage, were significantly higher in the baicalin-treated group than in the control group. To confirm that the SHH signaling pathway is involved in the mechanism by which baicalin improves embryonic development, we treated embryos with baicalin in the absence or presence of cyclopamine (Cy), an inhibitor of this pathway. Cy abolished the effects of baicalin on in vitro embryonic development. In conclusion, baicalin improves the in vitro developmental capacity of PA and IVF pig embryos by inhibiting ROS production and apoptosis, regulating mitochondrial activity and activating SHH signaling.

The developmental competence of oocytes parthenogenetically activated by an electric pulse and anisomycin treatment. Biotechnol Lett 2016; 39:189-196. [PMID: 27864653 DOI: 10.1007/s10529-016-2249-2] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2016] [Accepted: 11/01/2016] [Indexed: 10/20/2022]
Abstract
OBJECTIVE The aim of this study was to investigate the developmental competence of oocytes parthenogenetically activated by an electric pulse (EP) and treated with anisomycin and to determine whether this method is applicable to somatic cell nuclear transfer (SCNT). RESULTS Embryos derived from porcine oocytes parthenogenetically activated by an EP and treatment with 0.01 µg/mL anisomycin had a significantly improved in vitro developmental capacity. Furthermore, 66.6% of blastocysts derived from these embryos had a diploid karyotype. The blastocyst formation rate of cloned embryos was similar between oocytes activated by an EP and treated with 2 mM 6-dimethylaminopurine for 4 h and those activated by an EP and treated with 0.01 µg/mL anisomycin for 4 h. The level of maturation-promoting factor was significantly decreased in oocytes activated by an EP and treated with anisomycin. Finally, the mRNA expression levels of apoptosis-related genes (Bax and Bcl-2) and pluripotency-related genes (Oct4, Nanog, and Sox2) were checked by RT-PCR. CONCLUSION Our results demonstrate that porcine oocyte activation via an EP in combination with anisomycin treatment can lead to a high blastocyst formation rate in parthenogenetic activation and SCNT experiments.
