Gene transfer 101: the basics of cutting, copying, pasting and cloning genes • An introduction • Step-by-step
How does genetic engineering work? • Cut out desired DNA using • Insert DNA into plasmid • Insert plasmid (vector) into host cell
Genetic Engineering: Making Human insulin • E. Coli make human insulin
Genetic Engineering: Making Factor IX in sheep… 1997: Factor IX isolated and purified from sheep’s milk to treat one hereditary form of haemophilia (Haemophilia B, Christmas Disease)
The brave new world of genomics GENOMICS – analysis of the structure and function of genomes…
Learning about your genome • 2 out of 3 of us will die of a genetically related disease • Many (some say all) diseases have a genetic cause • Genetic report cards can identify ‘potential risk’ of future illnesses
Do you want to know your genome? Do you want to know your genome? Are you sure?
Gene therapy • Find defective genes and ‘fix them’ • Insert a healthy normal gene or gene product (lipid, protein)to achieve normal function • Most effective for single gene disorders: cystic fibrosis, Sickle Cell disease,
Pharmacogenomics Uses information about your genetic make-up to determine the drug, and drug doses, that will work best for you Currently used for treatment of: • HIV • Breast cancer • Colon cancer • Mental illness
Using our genome to understand human evolution By sequencing and databasing genes, we can see similarities and differences between species • The closer the genome match, the closer their evolutionary history • Human Chromosome 2 came from fusion of two great ape chromosomes • Karl Miller on human evolution • The time-tree of evolution
Ethics and the human genome How companies are patenting your genetic code
