What are the three major U.S. government agencies regulating biotechnology in the slides?
FDA (Food and Drug Administration), EPA (Environmental Protection Agency), and USDA (United States Department of Agriculture).
What are the main responsibilities of the FDA, EPA, and USDA?
FDA: safety of food, drugs, and medical devices; EPA: protection of human health and the environment; USDA: protection and regulation of agriculture and livestock.
What guidelines govern genetically modified organisms used in U.S. research laboratories?
The National Institutes of Health (NIH) provides guidelines for research involving genetically modified organisms and recombinant or synthetic nucleic acids.
How does the FDA regulate foods produced from genetically engineered plants?
According to the slides, genetically engineered foods must meet the same applicable safety, labeling, and other requirements as other FDA-regulated foods.
What was the purpose of the National Bioengineered Food Disclosure Law of 2016?
It required the USDA to establish standards for disclosing bioengineered ingredients in foods, including labeling guidelines.
What is the Non-GMO Project?
A nonprofit organization that offers third-party verification and labeling for products that meet its standards concerning genetically modified ingredients.
What is APHIS, and what is its role in biotechnology regulation?
The USDA's Animal and Plant Health Inspection Service, responsible for protecting agriculture and overseeing relevant activities involving genetically engineered plants.
What environmental concerns does the EPA evaluate regarding biotechnology?
Effects of genetically engineered crops, microorganisms, industrial processes, biofertilizers, biosensors, and biofuels on human health and the environment.
Who is responsible for proving that a new therapeutic product is safe and effective?
The manufacturer must provide adequate evidence of safety and effectiveness to the FDA before the relevant product can receive approval.
Which biotechnology-based healthcare products are regulated by the FDA?
Therapeutic drugs, medical devices, diagnostic tools, and tests, including products such as glucose meters and artificial joints.
What is preclinical research?
Research conducted before human clinical trials to investigate a potential therapy's biological activity, safety, and effective dosage using laboratory and animal models.
What is the difference between in vitro and in vivo preclinical testing?
In vitro testing occurs outside a living organism, such as in cell cultures; in vivo testing occurs within a living organism, such as a mouse or rat.
Why are mice, rats, and cell cultures commonly used in early preclinical research?
They can be relatively inexpensive, allow controlled testing, and often have short generation times, enabling efficient initial experiments.
What are major limitations of using animal models to test drugs?
Animal results may not accurately predict human responses; studies can be expensive and raise ethical concerns.
What is an organ-on-a-chip?
A microfluidic device containing channels lined with human cells that simulate aspects of organ structure and function for experimental testing.
What is a transgenic animal, and why might researchers use one?
An animal genetically engineered to express, inhibit, or lack selected genes; it can model human disease or express a drug target for testing.
What is a randomized clinical trial?
A human research study in which participants are assigned by chance to treatment groups, helping reduce selection bias.
What is a placebo-controlled trial?
A trial comparing a treatment against an inactive substance resembling the treatment, to assess whether observed effects result from the active therapy.
What is a double-blind clinical trial, and why is it useful?
Neither participants nor treating investigators know the assigned treatment, helping reduce expectations and observer bias.
What is the main purpose of Phase 1 clinical trials?
Test safety, dosage, metabolism, and drug behaviour in a small group, often fewer than 100 participants, who may be healthy volunteers.
What is the main purpose of Phase 2 clinical trials?
Evaluate whether a drug helps people with the target disease, typically in approximately 100–300 participants, while continuing safety assessment.
What is the main purpose of Phase 3 clinical trials?
Test effectiveness and side effects in large groups, often hundreds to thousands of patients, before potential approval.
How are animal and human clinical research overseen differently?
Animal research is reviewed by animal-care committees and relevant welfare rules; human research is reviewed by ethics boards that protect participants' rights, safety, and consent.
What is an Institutional Animal Care and Use Committee (IACUC)?
A U.S. institutional committee that reviews and oversees animal research to ensure experiments are justified and animals are treated humanely.
What must an IACUC consider when reviewing animal research?
Whether animal use is necessary, whether the chosen species is appropriate, whether animal numbers are minimized, and whether humane care is provided.
What is the Animal Welfare Act (AWA)?
A U.S. law setting standards for certain research animals' housing, feeding, sanitation, ventilation, veterinary care, and humane treatment.
What limitation of the Animal Welfare Act is emphasized in the presentation?
The slides state that rats and mice are excluded; specifically, the federal AWA excludes rats and mice bred for research, though other animal-care requirements may apply.
What requirements apply to animal research at institutions receiving U.S. Public Health Service research support?
Applicable Public Health Service animal-care requirements and the Guide for the Care and Use of Laboratory Animals cover the care and use of research animals.
What is Good Clinical Practice (GCP)?
An internationally recognized quality standard for designing and conducting clinical trials while protecting human participants and ensuring reliable research data.
What organization developed the international GCP guidelines discussed in the slides?
The International Conference on Harmonisation (ICH), which provides internationally coordinated pharmaceutical research standards.
What is an Institutional Review Board (IRB)?
An independent review body that evaluates human research proposals to protect participants' rights, welfare, and safety.
What information and safeguards should human research participants receive?
Disclosure of the study's purpose, methods, and risks; appropriate recruitment; written informed consent; confidentiality; and protection of vulnerable participants.
What are the three major categories of biotechnology laboratory waste?
Nonhazardous liquid/solid waste, biohazardous waste, and toxic or hazardous chemical waste.
What is biohazardous waste?
Waste that may contain infectious or potentially harmful biological materials, such as blood, tissues, microbial cultures, virus stocks, and contaminated sharps.
How may biohazardous waste be disinfected or sterilized?
Methods described in the presentation include steam sterilization (autoclaving), gas sterilization, and chemical disinfection.
What properties can make laboratory waste toxic or hazardous?
It may be poisonous, radioactive, flammable, explosive, corrosive, carcinogenic, mutagenic, teratogenic, or capable of accumulating in organisms.
How is toxic chemical waste managed in the presentation?
Hazardous waste may be sealed for disposal in designated landfills or destroyed using suitable incineration; manufacturers also try to reduce waste generation.
Why is nanotechnology a regulatory and safety concern?
Nanoparticles can have unusual properties and may create health or environmental risks, requiring assessment of exposure, toxicity, and disposal.
How do the EPA and NIOSH address potential nanomaterial hazards in the slides?
EPA requires certain reporting and recordkeeping under the Toxic Substances Control Act; NIOSH investigates possible occupational health risks from nanoparticles.
What does OSHA stand for, and what is its purpose?
Occupational Safety and Health Administration, a U.S. Department of Labor agency that establishes and enforces workplace safety and health standards.
What is PPE, and what examples are important in biotechnology laboratories?
Personal protective equipment; common laboratory examples include protective coats, safety glasses, and gloves.
What workplace safety responsibilities are emphasized under OSHA?
Reducing hazards, training employees in safe handling of hazardous materials, using appropriate PPE, and maintaining records of work-related injuries and illnesses.
What basic worker right is protected by the U.S. Occupational Safety and Health Act?
Workers have the right to a workplace that meets applicable safety and health requirements intended to reduce preventable hazards.
