2. Gene Therapy Flashcards
2 Types of Drugs
- Small molecules (chemicals)- MOST DRUGS IN THIS CATEGORY
- Biologics (large biomolecules) ie. proteins, genes, cell therapies, vacancies
3 Top gene disease trials
- cancer
- genetic disease
- infection
Gene therapy approval 2012
- lipoprotein lipase (rare disorder) deficiency, $1M, 31 patients treated worldwide
Gene therapy approval 2017
- for hereditary disease
- CAR-T therapies (cellular therapies involving genetic manipulation)
Gene therapy approval 2019
gene therapy for Spinal muscular atrophy (SMA)
Today, there are ___ FDA approved gene therapies
5
Many receptor proteins are found in the ______ ______
plasma membrane
______ Directs the cell’s activities
DNA
______ are organization units of DNA
Genes
DNA Structure Base Pairs
A-T
C-G
DNA
the cell’s genetic information
mRNA
the DNA’s messenger
Proteins
are huge chains of amino acids & carry out cell functions
Codon
every group of 3 bases on an mRNA (ie:UGA)
Each ______codes for an amino acid
codon
Amino acids
building blocks of proteins
RNA is made up of…
AUGC
Genetic code
converts RNA information to amino acid information
Genetic variation & mutations
An individual’s DNA can be mutated by errors during DNA copying (DNA replication) or by the action of DNA damage
All proteins are made out of ____ building blocks, called amino acids
21
Hydrophobic amino acids
have carbon-rich side chains, which don’t interact well with water
Hydrophilic or polar amino acids
interact well with water
Charged Amino Acids
interact with oppositely charged amino acids or other molecules.
Building blocks of protein
C, O, H, N, S
Building Blocks of amino acids
- carboxyl group
- amino group
- alpha carbon
- side chain
Antibodies
protect us from disease by recognizing and binding to pathogens such as viruses, and targeting them for destruction by the immune system
Gene therapies
when disease mechanism involves a single gene
2 Case Studies for gene therapy
- RPE65 Gene therapy to the eyes
- Beta thalassemia therapy (cant produce enough beta globin)
