Gene therapy involves introducing genes into cells to treat or prevent disease. This document discusses using gene therapy to treat cancer by delivering the p53 tumor suppressor gene via an adenovirus vector. The adenovirus binds to receptors on cancer cells and injects the p53 gene into the nucleus. This gene then causes cancer cells to self-destruct without harming normal cells, potentially providing a treatment for cancers like liver cancer, lung cancer, and cancer of the lower lip.

2. What Are Genes?
Genes are carried on
chromosomes and are the basic
physical and functional units of
heredity
Genes are specific sequences of
bases that encode instructions on
how to make proteins
When genes are altered so that the
encoded proteins are unable to
carry out their normal functions,
genetic disorders result

5. Diseases For Applying Gene Therapy
Disease Defect Target cell
Severe combined Bone marrow cells or
immunodeficiency T-lymphocytes
Hemophilia Liver, muscle
Cystic fibrosis Lung Cells
Cancer Many cell types
Neurological diseases Parkinson’s/ Alzheimer's Nerve Cells
Infectious diseases AIDS, hepatitis B White Blood Cells

9. HOW IS GENE THERAPY ADMINISTERED?
INJECTION INTO PLEURAL AND PERITONEAL CAVITIES DIRECT INJECTION TO TUMOR
INTRAVENOUS INFUSION

10. The adenovirus
containing the p53 tumor
suppressor gene binds to
the receptor in the cell
membrane of the cancer
cell
HOW DOES GENETHERAPY WORKS INTHE CANCER
CELL?

11. The adenovirus is
then packaged in a
vesicle
The vesicle proceeds
to the cell nucleus
The vesicle breaks
down, releasing the cell
nucleus
The adenovirus
injects its gene, which
contain the p53

12. The adenovirus
injects its gene, which
now includes the p53
tumor suppressor
gene, into the cell
nucleus
The cancer cell then
makes p53 protein

13. The p53
protein
causes the
cancer cell to
self destruct
without
affecting

normal cell
