Abstract

Transgenic animals are employed to synthesize pharmaceutical recombinant proteins for three decades.  There are many problems to use farm mammalian animals for recombinant production such as high cost of production and maintenance, long generation interval, toxic effects of some human-source pharmaceutical proteins in other mammalian and incompatibility of human-source glycosylation with the other mammalian' glycosylation that all lead to low efficiency. Thus, transgenic poultry has been considered as the bioreactor of recombinant protein production. Increasing demand for pharmaceutical human proteins caused to make considerable efforts to develop transgenic poultry producing eggs contain recombinant protein. In the present review, at the first, transgenic animal and poultry are compared for their benefits and limitations. Then, the protein content of the egg, the features, gene and promoter of the egg are studied. After that, the recent achievements of the producing pharmaceutical recombinant proteins are considered. In the following, there are some explanations about gene transformation approaches in poultry, including sperm-, testis-, PGCs, and blastocyst-mediated methods depending on CRISPR/Cas9, Retroviral vectors, and DNA microinjection techniques, and embryonic manipulation approaches such as windowing and Ex ovo for introducing and injecting transformed cells into eggs.

Abstract

Nanoparticles recently play remarkable roles in modern agriculture and biotechnology due to specific exclusively physicochemical and biological characteristics of the particles. In recent years, nanoparticles are been using as fertilizers and elicitors to improve crops. Nutritionists are constantly seeking natural antioxidants without side effects to using for healthcare and treatment. Asparagus officinalis L. as medicinal plant treated by iron (0, 10, 50 and 100 mg/L) and selenium (0, 0.5,and 1 mg/L) nanoparticles as nano elicitors. Then the antioxidant capacity of A. officinalis L. was detected and measured by α, α-diphenyl-β-picrylhydrazyl (DPPH) assay, for assessment of the antioxidant activity. The iron nanoparticlesconcentration significantly increases the antioxidant activity of both male and female asparagus stem, as well as selenium nanoparticles. When combined iron and selenium used as nano elicitors then cause the antioxidant activity significantly decreases. But the integration of two nano elicitors (iron and selenium) decreased antioxidant capacity while the use of nano-selenium could enhance antioxidant capacity. The application of nano elicitor increased antioxidant capacity in the female stem than male.
