Vitrification is becoming a preferred method for pre-implantation embryo cryopreservation. The objective of this study was to determine the differentially expressed genes in vivo- and vitro-produced bovine embryos after vitrification. In vitro- (IVF) vivo-derived (IVV) blastocysts were identified as follows: fresh (IVF-F), vitrified (IVF-V), (IVV-F), (IVV-V). microarray results showed that 53 regulated between IVF IVV, 121 (P < 0.05). There 6, 268, 962, 17 IVF-F × IVV-F, IVF-V IVV-V, IVF-V,...

Abstract The cryopreservation of pronuclear‐stage embryos has particular importance in transgenic technology and human assisted reproductive (ART). objective this study was to improve the efficiency mouse embryos. Two vitrification methods (solid surface (SSV) vs. cryotube) have been compared with special emphasis on effect exposure solutions for various times sugar content (trehalose, sucrose, or raffinose) solutions. Pronuclear‐stage were either exposed 1 M dimethyl sulfoxide (DMSO) +...

Breast cancer is the most common malignancy predominantly affecting women. To date, numerous numbers of studies were reported novel genetic contributors with diagnostic, prognostic, and therapeutic potential for breast carcinogenesis. However, role urotensin-II in carcinogenesis has not been elucidated yet. Urotensin-II a somatostatin-like cyclic tiny peptide identified by its potent vasoconstrictor activity. Soon after discovery, involvement many disease states as well expression various...

Embryo transfer (ET) is among the key factors determining overall efficiency of transgenic technology in mouse. A successful ET depends other on quality transferred embryos, foster mothers and anaesthetic reagents techniques. Anaesthesia-caused deaths suboptimal procedures are which reduce success experiments mouse colony maintenance.

Abstract Cryopreservation of pronuclear‐stage embryos would be useful for transgenic technology and genome preservation purposes. We compared a novel vitrification technique (solid surface vitrification, SSV) with another method in straws cryosurvival to generate progeny from cryopreserved mouse zygotes following microinjection. The SSV solution consisted 35% ethylene glycol (EG), 5% polyvinyl‐pyrrolidone (PVP), 0.4 M trehalose M2 supplemented 4 mg/ml BSA; the straw was 7 EG plus BSA. In...

Abstract Here we describe the generation of transgenic mice carrying type III fish antifreeze protein (AFP) gene and evaluate whether AFP protects mouse ovaries testes from hypothermic storage. AFPs exist in many different organisms. In fish, protect host freezing at temperatures below colligative point by adsorbing to surface nucleating ice crystals inhibiting their growth. The expression holds great promise for conferring freeze‐resistant plant animal species. also exhibits a potential...
