Embryotoxicity of Transgenic Rice TT51 and Cry1Ab Bt Insecticidal Toxin in Rat Post Implantation Whole Embryo Culture

TT51, with a synthetic Cry1Ab/CryAc gene from Bacillus thuringiensis Berliner, was the first genetically modified (GM) plant officially certificated in China. This study was undertaken to investigate potential embryotoxicity of TT51 on rats. Whole embryo culture (WEC) is an effective method for safety evaluation when culture medium, containing substances derived from GM food, is available. Rat ...

Rat post-implantation embryo culture using heterologous serum.

In the present study sera from twelve species have been compared to rat serum and ascitic fluid for their ability to support the growth of post-implantation rat embryos. No alternative to rat serum or rat ascitic fluid was found. The basis for this apparent species specificity was further analysed. A marked improvement in embryonic growth was seen when rat serum was added to the heterologous se...

Cry1ab/c in different stages of growth in transgenic rice Bt-shanyou63.

The relationship between the mRNA level and the corresponding protein level of the cry1Ab/c gene is not well characterized in transgenic rice (Bt-ShanYou63). In this study, we compared cry1Ab/c mRNA and its protein expression in leaves at different growth stages in Bt-ShanYou63 rice. The results demonstrated that both cry1Ab/c mRNA and its protein levels changed at all of the growth stages. The...

Comparative pathogenesis of haloacetic acid and protein kinase inhibitor embryotoxicity in mouse whole embryo culture.

Haloacetic acids (HAs) are embryotoxic contaminants commonly found in drinking water. The mechanism of HA embryotoxicity has not been defined, but may be mediated in part by protein kinase C (PKC) inhibition. This study was conducted to evaluate the pathogenesis of HA embryotoxicity, and to compare these data with those from specific (Bis I) and non-specific (staurosporine) inhibitors of PKC. E...

Loop replacements with gut-binding peptides in Cry1Ab domain II enhanced toxicity against the brown planthopper, Nilaparvata lugens (Stål)

Bacillus thuringiensis (Bt) Cry toxins have been used widely in pest managements. However, Cry toxins are not effective against sap-sucking insects (Hemiptera), which limits the application of Bt for pest management. In order to extend the insecticidal spectrum of Bt toxins to the rice brown planthopper (BPH), Nilaparvata lugens, we modified Cry1Ab putative receptor binding domains with selecte...
