A DNA construct containing the human alpha 1-antitrypsin gene including 1.5 and 4 kb of 5' and 3' flanking sequences, was microinjected into the pronucleus of rabbit embryos. The recombinant human protein was (a) expressed in the blood circulation of F0 and F1 transgenic rabbits at an average concentration of 1 mg ml-1, (b) shown to be fully active and (c) shown to be separable from its rabbit counterpart. Transgenic rabbits might represent a novel source of human proteins of therapeutic interest.

Protein drug production encompasses various methods, among which animal bioreactors are emerging as a transgenic system. Animal bioreactors have the potential to reduce production costs and increase efficiency, thereby producing recombinant proteins that are crucial for therapeutic applications. Various species, including goats, cattle, rabbits, and poultry, have been genetically engineered to serve as bioreactors.

Background: Gene-edited pigs for xenotransplantation usually contain one or more transgenes encoding human complement regulatory proteins (CRPs). Because of species differences, human CRP(s) expressed in gene-edited pigs may have difficulty inhibiting the activation of exogenous rabbit complement added to a complement-dependent cytotoxicity (CDC) assay. The use of human complement instead of rabbit complement in CDC experiments may more accurately reflect the actual regulatory activity of human CRP(s).

Cleft palate is one of the most prevalent congenital craniofacial birth defects in human congenital facial anomaly. Severe cleft palate is usually accompanied by alveolar bone defects (ABDs). Growth factors (GFs) are considered as desirable opportunity to promote the craniofacial healing post the surgery.

This occurs despite noted advances in surgical care in the past 50 years. Mitochondrial oxidative damage pathways initiate PTOA after severe injuries like intraarticular fracture that often require surgery and contribute to PTOA after less severe injuries that may or may not require surgery like meniscal injuries.

Glyphosate resistance is a critically important trait for genetically modified (GM) crops. Mutation of the rice EPSPS gene results in a high level of glyphosate resistance, presenting significant potential for the development of glyphosate-tolerant crops. The resistance of rice to glyphosate is correlated with the expression levels of resistance genes.
