Q & A

What is the main topic of the presentation?

The main topic of the presentation is the future of medicine, focusing on the potential of genome editing technologies like CRISPR to treat and potentially cure diseases by modifying our genetic code.

What does the speaker mean by 'genetic destiny'?

Genetic destiny refers to the idea that our health and predisposition to certain diseases are determined by our genetic makeup. The speaker explains that advances in genome editing can now allow us to overcome or modify this genetic fate.

How does CRISPR work in genetic medicine?

CRISPR is a technology that allows for precise modification of the DNA sequence in nearly any organism. It was originally a bacterial immune system, but scientists have adapted it to edit the genome of humans and other organisms, opening up possibilities for treating genetic disorders.

What role does evolution play in the development of genetic diseases?

Evolution often leads to the development of genetic traits that were once beneficial but may no longer be suited to modern environments, resulting in what the speaker calls 'evolutionary hangovers'—genetic imperfections that can contribute to diseases like sickle cell anemia.

What is the difference between traditional medicine and genetic medicine?

Traditional medicine typically treats symptoms of diseases, while genetic medicine aims to address the root causes of diseases by modifying the underlying genetic code, potentially offering a more permanent solution.

What is the significance of the speaker’s personal connection to cardiovascular disease?

The speaker shares a personal connection to cardiovascular disease, noting that his father had multiple heart attacks, which drives his passion for advancing genetic medicine to potentially prevent such diseases in the future.

What potential does genetic medicine have for treating cardiovascular disease?

Genetic medicine, specifically through CRISPR, holds the potential to significantly reduce harmful cholesterol levels (LDL-C), which is a key contributor to cardiovascular disease. This could offer a new standard of care, potentially lowering the risk of heart attacks globally.

What specific advancements in CRISPR technology have been made in recent years?

Recent advancements in CRISPR technology include engineering more potent, safe, and effective genome editing tools. This has led to promising results, such as reducing cholesterol levels by more than 50% in animal models, showing potential for human applications.

What are the challenges that remain in implementing genetic medicine at a larger scale?

The challenges include ensuring that genetic treatments are safe, effective, and accessible to a broad population. There are also technical hurdles in improving CRISPR’s precision and delivery methods to ensure it works reliably across different genetic disorders.

How does CRISPR by Design differ from traditional CRISPR technologies?

CRISPR by Design involves engineering and testing tens of millions of possible variations of CRISPR molecules to improve their efficiency and safety. This allows for the creation of more advanced genome-editing tools that can be applied to a wider range of diseases.
