Gene Therapy Development for Inherited Disorder


Genetic disorder is a genetic problem caused by one or more abnormalities formed in the genome with complex and multifactorial pathogenesis. The disease with single or multiple genetic mutations is likely associated with lifestyles and environmental factors. With the identification of numerous genes associated with inherited diseases, gene therapy can be viewed as a promising option in some instances. Creative Biolabs possesses the world first-class technology platforms and skillful scientific teams in the field of gene therapy development. We are able to provide costumer services and advanced technologies for your research, such as the addition of a normal copy of the mutated gene, modification of messenger RNA to avoid the consequences of mutation, inhibition of expression of a mutated gene, and repair of the mutated gene by genetic editing. We are glad to cooperate with our client and accelerate gene therapy products development for a better tomorrow.

Monogenic disorder results from a single mutated gene and the mutation may be present on one or both chromosomes inherited from each parent. Currently, there is a growing list of single-gene diseases considered as targets for gene therapy. Monogenic disorders include cystic fibrosis (CF), polycystic kidney and Tay-Sachs disease, β-thalassemia and sickle cell disease, etc. The use of modified versions of the defective β-globin gene or recombinant retrovirus vectors contains either the human γ-globin or β-globin genes that can prevent red cell sickling. Hemophilia B is another monogenic disorder caused by the factor IX deficiency that is a critical component in the blood-clotting pathway. Some groups have injected the recombinant AAV designed to express factor IX gene into muscle or hepatic artery for the treatment of hemophilia B.

Multifactorial disorders are caused by the abnormalities on two or more disease-causing genes. Compared with monogenic disorder, it not only determined is by genetic factors, but also plays a role together with genetic factors and environmental factors. Common medical problems such as diabetes, congenital heart disease and asthma, and obesity belong to multifactorial disorders. Gene therapy approaches have been introduced to treat multiple-gene disease, such as the management of diabetes. The use of AAV vector containing insulin and glucokinase genes keeps normoglycemic via long-term efficacy of diabetes gene therapy without the supply of exogenous insulin. Another successful example is injecting lentivirus vector that carries insulin gene into the diabetic rats, which allows liver cells to sense glucose, in turn, synthesize, release and store human insulin as a response.
