Genetically Manipulated Animals By: Craig Schimmer Ryan Richards Andrew York Grayson Phillips

What is a Transgenic Animal and How is it produced? l Webster's Definition: l Transgenic: being or used to produce an organism or cell of one species into which one or more genes of another species have been incorporated l l Ex: a transgenic mouse or transgenic crops How it’s done? l 3 ways: Microinjection of Pronuclei l Retroviral Insertion l Stem Cell Insertion l

Examples of Transgenic Animal Uses l Aedes Mosquitoes males were genetically manipulated to be sterile, released into the wild to mate with the females, thus reducing the population of mosquitoes because the female only mates once. Pro or Con?

PRO!!! l Reducing the chance of malaria outbreaks and other diseases that mosquitoes carry l Combating the number one parasitic disease in the world that could save thousands of lives l Reduces the cost for further medical relief for third world countries who have malaria outbreaks

Next Example l Transgenic Cows being released into general population that have higher than normal muscle mass l Resulting in higher amount of beef per cow and lower beef prices in the market Pro or Con?

CON!!! l l The consumption of genetically altered animals have not been thoroughly studied and could have unforeseen consequences, possibly even be fatal to humans if consumed The are no FDA regulations on genetically altered animals that are made for human consumption The companies producing these products, are not required to label the products as genetically altered animals Here is a thought, you could have possibly eaten a genetically altered animal today!!!!

Pros vs. Cons l Agriculture l Animal Cruelty l Medicine l Higher l Industry l Unforeseen Consequences Mortality Rate l Ethical and Moral Issues

Agriculture - Pros l The Enviro. Pig l A reduced amount of Phosphorus produced in the waste of these pigs l l More environmentally friendly by reducing greenhouse gases Transgenic cattle l l Created to produce milk containing particular human proteins, which may help in the treatment of human emphysema. Created to produce milk for specific dairy products.

Agriculture - Cons l Unexpected Genotypic traits of Transgenic Animals l Enlarged organs l Lack of physical features l Addition of unwanted physical features l Transgenic animals not proven safe for human consumption l No FDA regulation or warning of genetically altered animal products.

Medicine - Pros l Transgenic Mice l l Used in working with study the role of actively dividing blood cells in studying how inflammation, autoimmune syndromes and many metabolic alterations form. Cancer Resistant mice l l Professors of UK found the “Par-4” gene in the prostate that kills cancer Cells but normal cells Transgenic Mosquitoes l Aedes aegypti OX 513 A males were genetically manipulated to contain a lethal allele that kill the progeny in late larvae or pupae stage were released into the wild to mate with the females, thus reducing the population of mosquitoes because the female only mates once. l Reducing the chance of dengue or malaria outbreaks and other diseases the mosquitoes carry

Medicine – Pros Cont’d l Xenotransplantation l Transplantation of animal organs and cells into humans l Uses could include heart, lungs, liver, and kidneys l Bone Marrow Transplant Mice

Medicine - Cons l Animal Cruelty l l Although, a pro for humans, the suffering these animals go though living with human diseases is a form of animal cruelty Virus Jumping in Xenotransplantation l Whenever animals organs are transplanted into humans, the diseases that affect those animals can be transferred into humans and can be transmitted to the rest of the population

Industry - Pros l Glo. Fish l l Genetically altered Zebra Fish that glow Created a new market for “decorative fish” that people wanted to purchase l l Simply put, they are genetically altered pets Spider Silk Sheep l l Goats are genetically altered to produce biosynthetic milk with spider silk proteins. These proteins are used in the production of bullet proof clothing reducing the cost of such items to law enforcement and military.

Industry - Cons l High Mortality rate l 1 out of 100 attempts produce a successful genetically manipulated animal. Expensive to produce these animals l KFC chickens produced just for consumption l l No feathers or wings

Unforeseen Consequences l l Scientist don’t know what the future holds for evolution among nature and humans in regard to transgenetics because the unknown consequences they may bring forth. The science of transgenesis is new and the possibilities are vast, but the consequences are unknown. Another issue is where to draw the line ethically. What is the difference between for the good of mankind and playing God.
