Genetically modified chickens offer a cost-effective and efficient system for producing therapeutic protein drugs. This avian bioreactor technology utilizes gene editing for enhanced recombinant protein production in egg whites.
Area of Science:
- Biotechnology
- Molecular Biology
- Animal Science
Background:
- Traditional protein drug production methods face challenges in cost and efficiency.
- Transgenic animal bioreactors are an emerging alternative for recombinant protein production.
- Various species have been explored, but avian systems show unique promise.
Purpose of the Study:
- To review and compare different protein drug expression systems.
- To highlight the potential of genetically modified chickens as a bioreactor system.
- To discuss the advantages of avian bioreactors for therapeutic protein production.
Main Methods:
- Comparative analysis of microbial, yeast, plant, and mammalian cell expression systems.
- Focus on genetically modified chickens utilizing ovarian cell expression.
- Application of advanced gene editing technologies like CRISPR/Cas9.
Main Results:
- Avian bioreactors offer short production cycles and high efficiency.
- Expression products in egg whites are easier to purify and closer to their natural state.
- CRISPR/Cas9 enables precise genetic modification for improved protein characteristics.
Conclusions:
- Genetically modified chickens represent a highly promising and sustainable bioreactor system for protein-based drugs.
- This technology can lead to enhanced production of recombinant therapeutics with reduced immunogenicity.

RNA is the Missing Link Between DNA and Proteins
In the early 1900s, scientists discovered that DNA stores all the information needed for cellular functions and that proteins perform most of these functions. However, the mechanisms of converting genetic information into functional proteins remained unknown for many years. Initially, it was believed that a single gene is...

Transgenic Plants
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...
