Study Notes
How a Petunia Experiment Led to Breakthrough in Cancer and AIDS Treatment
- In 1998, Andrew Fire and Craig Mello discovered RNA interference (RNAi), a process where double-stranded RNA can silence genes, contradicting the established "central dogma" of biology.
- David Baulcombe's research on viral resistance in plants led to the understanding that foreign RNA mimicked viruses, contributing to the fundamental understanding of RNAi.
- Scientists found small stretches of double-stranded RNA interfering with gene action in fruit flies and plants, leading to the realization that short, double-stranded RNAs could be tailored to target specific genes.
- RNAi's medical potential for turning off cancer-related genes, preventing virus infections, and treating tissue rejection and liver disease was recognized.
- In the test tube, scientists made human cells resistant to the polio virus and HIV using RNAi, prompting research into introducing short RNA strands directly into cells for medical use.
- Andrew Fire and Craig Mello won the 2006 Nobel Prize in medicine for their RNAi research, which was initially conducted on nematode worms and later found to occur in human cells.
- RNAi is being widely used in basic science to study gene function and holds promise for novel therapies in the future, according to the Nobel Assembly.
- The discovery of RNAi contradicted established biological principles and opened up new possibilities in medical science.
- The research on RNAi was initially focused on nematode worms and later expanded to human cells, demonstrating its potential for clinical treatments.
