Stably Transfected Human Androgen Receptor-α Transcriptional Activation Assay for Detection of Androgenic Agonist/Antagonist Activity of Chemicals


An important aspect of the OECD work on Environment, Health and Safety focuses on the regulatory management of chemicals, taking into account the possible effects of chemicals on human health and the environment.

 

In the context of the Chemicals Programme the work covers chemicals, including, e.g. industrial chemicals and pesticides.


In 1996, the OECD established a Special Activity on Endocrine Disrupter Testing and Assessment with the objectives of

  • Providing information and co-ordinating activities

  • Developing new and revised existing Test Guidelines to detect endocrine disrupters; and

  • Harmonising hazard and risk characterisation approaches

This activity was launched at the request of the Member countries and the Business and Industry Advisory Commitee to the OECD (BIAC) to ensure that testing and assessment approaches for endocrine disrupters would not substantially differ among countries.

 

Peer Review Package for the Fish Sexual Development Test

The Fish Sexual Development Test is intended for the detection and characterization of endocrine active substances. Validation studies of this test have been coordinated by Denmark, on behalf of the Nordic countries. The validation is now reviewed by an international panel of reviewers. The peer review package includes the draft validation reports of Phase 1 and Phase 2 and a preliminary draft Test Guideline.

 

Peer Review Package for the Androgenised Female Stickleback Screening Assay

The Androgenised Female Stickleback Endocrine Screening Assay is mainly intended to detect anti-androgen activity. Validation studies of this test have been coordinated by the United Kingdom. The validation is now reviewed by an international panel of reviewers. The peer review package, provided by the United Kingdom, includes the draft validation report, a number of relevant scientific articles and a preliminary draft Test Guideline.

  • Validation report of the 21-day androgenised female stickleback endocrine screening assay
  • Intercalibration exercise using a stickleback endocrine disrupterscreening assay (Allen et al, 2008)
  • Three-Spined Stickleback: an Emerging Model in Environmental Endocrine Disruption (Katsiadaki et al, 2007)
  • Detection of the anti-androgenic effect of endocrine disrupting environmental contaminants using in vivo and in vitro assays in the three-spined stickleback (Jolly et al, 2009)
  • Development of a stickleback kidney cell culture assay for the screening of androgenic and anti-androgenic endocrine disrupters (Jolly et al, 2006)
  • Detection of environmental androgens: a novel method based on enzyme-linked immunosorbent assay of spiggin, the stickleback (gasterosteus aculeatus) glue protein (Katsiadaki et al, 2002a)
  • The potential of the three-spined stickleback (Gasterosteus aculeatus L.) as a combined biomarker for oestrogens and androgens in European waters (Katsiadaki et al, 2002b)
  • The model anti-androgen flutamide suppresses the expression of typical male stickleback reproductive behavior (Sebire et al, 2008)

Peer Review Package for the Updated Test Guideline 407

The validation of the Test Guideline 407 Repeat Dose 28-day Oral Toxicity Study has been updated to possibly detect endocrine disruption effects. Validation studies of the updated Test Guideline have been performed under the OECD Test Guidelines Programme. The validation is now being reviewed by an international panel of reviewers. The peer review package, submitted to the panel, includes the validation report, the draft and the current Test Guidelines and a Secretariat document to support the peer review panel.

Peer Review Package for the Hershberger Assay

The Hershberger bioassay is intended to detect androgen agonists, antagonists and 5α-reductase inhibitors. Validation studies of this test have been performed under the OECD Test Guidelines Programme. The validation of the Hershberger assay is now being reviewed by an international panel of reviewers. The peer review package, submitted to the panel includes the 3 validation reports, the draft test guideline and a Secretariat document to support the peer review panel. A background review document will soon be available on this website.
