Title: Working With Recombinant DNA


1
Working With Recombinant DNA
  • 2007 Information Session
  • Professor Marilyn Anderson
  • Chair, Genetic Manipulation Supervisory Committee

2
What is a GMO?
  • A genetically modified organism
  • An organism that has inherited traits from a GMO

3
Organisms that are not GMOs
  • Organisms declared by the Regulator not to be
    GMOs
  • Humans that have undergone somatic cell gene
    therapy
  • Mutant organism in which mutational event did not
    involve the introduction of foreign nucleic acid
  • Protoplast fusion between non-pathogenic bacteria
    or yeast

4
Organisms that are not GMOs
  • Recombinant organism formed by integration of DNA
    sequences of a genetic element that occurs
    naturally in the species and moves sporadically
    between genome sites
  • A plant formed by embryo rescue or protoplast
    fusion
  • Organism that results from the exchange of DNA if
    it is from the same species or if DNA exchange
    naturally occurs between those species

5
How is Gene Technology Research Regulated?
  • Gene Technology Act 2000 and Gene Technology
    Regulations 2001
  • To protect the health and safety of people, and
    to protect the environment by identifying risks
    posed by, or as a result of gene technology, and
    by managing those risks through regulating
    certain dealings with GMOs

6
Office of the Gene Technology Regulator (OGTR)
  • Administers legislation and assesses risks
    imposed by GMOS
  • Accreditation of organisations
  • Certification of facilities
  • Regulation of human cloning
  • Import and transport of GMOs
  • Regulation of GM products

7
Office of the Gene Technology Regulator (OGTR)
  • Informs and advises other regulatory agencies and
    the public about GMOs and GM products
  • Three key advisory groups
  • Gene Technology Technical Advisory Committee
    (GTTAC)
  • Gene Technology Ethics Committee (GTEC)
  • Gene Technology Community Consultative Committee
    (GTCCC)

8
Genetic Manipulation Supervisory Committee (GMSC)
  • Ensures that La Trobe University complies with
    gene technology legislation
  • Composition of the GMSC includes scientists
    (including a microbiologist, a molecular
    biologist and/or geneticist), a biological safety
    officer and a lay person

9
Duties of the GMSC
  • Assessing research proposals and determining
    classification
  • Inspecting PC1 and PC2 facilities
  • Reporting annually to the OGTR on research being
    conducted at the University
  • Training University staff and students on
    complying with OGTR requirements

10
What is a Dealing?
  • Conducting experiments with a GMO
  • Making, developing, producing or manufacturing a
    GMO
  • Breeding or propagating a GMO
  • Using a GMO to make something that is not a GMO
  • Growing, raising or culturing a GMO
  • Importing, sorting, transporting or disposing of
    a GMO

11
Types of Dealings
  • Exempt dealings
  • Notifiable low risk dealings (NLRD)
  • Licensed dealings
  • Not released to the environment (DNIR)
  • Released to the environment (DIR)

12
Exempt Dealings
  • Lowest perceived risk
  • All exempt dealings must be conducted in a PC1
    laboratory (at least)
  • Requires approval from the GMSC only
  • Exempt dealings include
  • Production or use of knockout mice
  • Any dealing with a whole animal if DNA/RNA has
    been introduced into somatic cells and cant give
    rise to infectious agents

13
Exempt Dealings
  • Any dealing involving shot-gun cloning of
    mammalian DNA in a host/vector system listed in
    part 2 of the schedule http//scaleplus.law.gov.au
    /html/pastereg/3/1664/0/PR000600.htm
  • Any dealing involving a host/vector system listed
    in part 2 of the schedule and providing no more
    than 10L of culture is produced if the donor DNA
  • Is not an oncogene
  • Is not from micro-organisms that can cause
    disease, or is fully characterized and will not
    increase the virulence or host range of the vector

14
Exempt Dealings
  • Does not code for a toxin with LD50lt100µg/kg
  • Is not uncharacterized DNA from an organism that
    produces toxins
  • The donor DNA includes viral sequences but is
    missing at least one gene essential for viral
    replication

15
Host/Vector Systems for Exempt Dealings
16
Notifiable Low Risk Dealing
  • Any dealing involving whole animals that involves
    genetic modification of the genome of the oocyte
    or zygote or early embryo
  • Any genetically modified plant providing it cant
    set seed or produce viable pollen that can escape
  • Any host and vector not mentioned in schedule 2
    if the host and the vector is incapable of
    causing disease (in humans, animals, plants or
    fungi)

17
Dealings Not involving Intentional Release
  • All dealings with GMOs that are not exempt
    dealings, NLRDs or on the GMO register, must be
    licensed by the Regulator AND the GMO is
    physically contained and is not released into the
    environment
  • The regulator assesses the application by
    preparing a risk assessment and risk management
    plan
  • All license conditions must be adhered to
  • All named investigators must sign the license

18
Dealings involving Intentional Release
  • A dealing with a GMO involves the intentional
    release of a GMO into the environment if the GMO
    is intentionally released into the open
    environment, whether or not it is released with
    provision for limiting the dissemination or
    persistence of the GMO or its genetic material in
    the environment
  • Examples include
  • grow a GM crop as a field trial
  • grow a GM crop commercially
  • release a GM fish into a waterway

19
Decision Tree for Approvals for Dealings with GMOs
20
Transportation of GMOs
  • Includes all movements of GMO from a certified
    facility to any location outside the certified
    facility
  • Includes all movements from a location specified
    in a licence to another location
  • You must include transportation of GMO in your
    dealing application
  • Transportation of GMO WASTE follows the same
    conditions

21
Conditions of GMO Transportation
  • The GMO must be wholly contained in a primary
    sealed container and
  • The primary sealed container must be packed in a
    secondary sealed unbreakable container
  • The secondary container must be labelled to
    indicate it contains GMOs, and the label must
    contain the name and telephone number of a
    contact person should the package be lost or
    damaged
  • Following transportation the primary and
    secondary containers must be decontaminated

22
Physical Containment 1 (PC1) Facilities
  • All exempt dealings must be performed in a PC1
    facility (at least)
  • Certified if the OGTR grant special dispensation
    for an NLRD to be conducted in a PC1 facility
  • Certified PC1 facilities inspected annually by
    the GMSC
  • Staff and students must be trained in PC1
    practices

23
PC1 Procedures
  • No eating, drinking, smoking or application of
    cosmetics
  • No storage of food or drink
  • Lab gowns must be worn and removed before leaving
  • Closed footwear must be worn
  • Safety glasses to be worn where appropriate to
    protect eyes and face from splashes and other
    hazards
  • Keep only the minimum required quantities of
    hazardous substances in the laboratory work area

24
PC1 Procedures
  • Clearly identify and date cultures. Do not store
    cultures for long periods of time on the bench
  • Take care to minimize the production of aerosols
    where work is being carried out on the bench
  • Clean up spills immediately and decontaminate the
    area
  • Decontaminate work benches at least daily and
    after each task is completed
  • Segregate specialized waste at point of discard
    and dispose of according to local regulations

25
Physical Containment 2 (PC2) Facilities
  • Unless granted special dispensation from the OGTR
    all NLRD work must be performed in a PC2 facility
  • Certified by the OGTR
  • Inspected annually by the GMSC
  • Staff and students must be trained in PC2
    practices and a record of this training must be
    kept

26
PC2 Procedures
  • Keep doors closed when work is in progress
  • No mouth pipetting
  • No eating, drinking, smoking or application of
    cosmetics
  • No storage of food or drink
  • Wear lab gowns and remove before leaving
  • Sterilise all biological waste
  • Wash hands before leaving
  • Dont moisten labels with the tongue

27
PC2 Procedures
  • Equipment that cant be steam sterilized must be
    chemically disinfected after use
  • Decontaminate work benches and surfaces with a
    disinfectant solution after spills and when work
    is completed
  • Material carried out of the laboratory to an
    autoclave or elsewhere must be in a closed
    unbreakable container
  • Minimize the creation of aerosols-sonicate or
    vortex in a biological safety cabinet
  • Clearly identify, date and appropriately store
    cultures

28
GMO Storage Policy
  • All GMOs must be stored in sealed containers that
    are clearly labeled so that GMOs are easily
    identifiable.
  • In order to ensure that GMOs are stored lawfully,
    they must be covered by a current dealing, or an
    application to store GMOs for future research.
  • GMOs must be stored inside a PC2 facility OR
  • in a cold storage cabinet that is either
    lockable or located in a secure area that
    prevents access to the cabinet from persons not
    responsible for its contents

29
State and National Ethical Principles
  • The Statement of Ethical Principles for
    Biotechnology in Victoria contains 8 principles
    (http//www.health.vic.gov.au/biotechnology/downlo
    ads/statement1794C0.pdf)
  • Respect for persons
  • Respect for animals
  • Respect for the natural environment
  • Respect for the public good
  • Benefit and harm
  • Justice and equity
  • Probity
  • Accountability
  • The National Framework for the Development of
    Ethical Principles in Gene Technology contains 9
    principles (http//www.ogtr.gov.au/rtf/committee/g
