Study Notes

Biomedical Research

Scientists need to use lab animals to study diseases in order to understand the cellular changes and genes involved in causing them.
The goal is to develop more effective treatments and diagnostics for diseases.
Mice are often used in cancer research; researchers manipulate their genes to cause various cancers.
Testing on humans is only allowed after the treatment or diagnostic method proves safe and effective on animals.

Agricultural and Veterinary Research

Increased dairy production is essential to feeding the growing global population.
Research in this field aims to understand environmental factors that promote optimal cow health and welfare.
Scientists may study the impact of dietary changes on cows' immune systems, digestion, and nutrient absorption.
Research may involve collecting blood samples, digesta samples from the rumen, and fecal samples.

Wildlife Research

Studying the endangered wolf and woodland caribou interaction requires locating and capturing individual animals.
Researchers use helicopters to capture wolves and caribou, either by darting them or using a net gun.
Once captured, animals have their age determined by pulling a tooth and blood is collected for DNA sequencing.
Research involves weighing individual animals and attaching radio collars for tracking their movements.

Hepatitis Research

Animal research played a critical role in understanding and fighting against hepatitis.
Initial research used mice, followed by a final step involving chimpanzees to demonstrate the presence of the virus in their blood.

Cancer Therapy Research

James P. Allison and Tasuku Honjo won the 2018 Nobel Prize in Physiology or Medicine for their discovery of cancer therapy by inhibiting negative immune regulation.
Their research demonstrated that by inhibiting the breaks on the immune system, cancer treatment could be revolutionized.
They found that mice with cancer could be cured by treatment with antibodies that inhibit the immune system's brakes, unlocking antitumor T-cell activity.
Their work paved the way for the development of human melanoma therapy, surpassing previous treatments.

How are Animals Used in Science?

Fundamental Research studies focus on the essential structure and function of organisms.
Medical and Clinical Studies aim to understand and treat diseases in humans and animals.
Regulatory Testing ensures the efficacy and safety of products and medications before human trials are allowed.
Development of Products and Medical Devices involves the development of products and devices to treat human and veterinary diseases.
Teaching and Training uses animals to communicate scientific concepts and develop practical skills in various fields.

Importance of Animal Research

Animal research is crucial for scientific progress and has led to significant medical breakthroughs.
It has contributed to the development of treatments for serious diseases, including diabetes, leukemia, HIV/AIDS, hepatitis, and cardiovascular disease.
Animal research has also led to advancements in surgical procedures, organ transplants, bioengineering, and medical imaging.
It plays a vital role in understanding wildlife and basic biological principles.

Regulation of Animal Research

Animal research in Canada is carefully regulated and supervised by the Canadian Council on Animal Care (CCAC).
The CCAC oversees and certifies the ethical treatment of laboratory animals at institutions across Canada.
They produce guidelines, conduct mandatory reviews and assessments, and require institutions to be accredited.
Animal research facilities are regularly inspected and monitored for animal care standards.
The CCAC promotes the adherence to the Three R’s: Replacement, Refinement, and Reduction.

The Three R’s of Animal Research

Reduction: Aims to minimize the number of animals used in research while still ensuring statistically significant results.
Replacement: Focuses on replacing animal use with alternative methods like cell culture, computer simulations, or using animals with lower sentience.
Refinement: Involves modifying procedures and husbandry practices to minimize pain and distress for animals involved in research.

Key Takeaways

The majority of research animals used in Canada are mice and fish.
Animal research is essential for medical advancements, human health, and improving the welfare of animals.
Animal research must demonstrate respect for animals and their wellbeing.
High-quality animal care is essential for producing high-quality scientific results.
