PSI Webinar: Statistics and the Ames Test

Tuesday 19th September 2017
2:00-3:00 pm (UK Time)

(Organised by the Toxicology Special Interest Group)

Presenter: David Lovell, St George’s Medical School, University of London

The bacterial reverse mutation assay (or the Ames test) has been in use in its present form for over 40 years. It is arguably the most successful in vitro test, used by hundreds of laboratories worldwide, on thousands of substances. The test aims to identify substances that can produce genetic damage and may lead to cancer in exposed individuals or to inherited mutation in offspring to cancer.

The design of the test is basically simple and numerous statistical tests have been proposed for the analysis of the data produced. Interpretation of the result aims at categorizing the chemical as either a genotoxin or a non-genotoxin. This provides an interesting example of the contrast between statistical significance and biological interpretation. Ames test results are also used in helping to develop in silico methods for predicting carcinogenicity.

This presentation will illustrate these issues and also discuss newer versions of the test and the continuing assessment of the role of the test in toxicology.

Upcoming Events

PSI VisSIG Wonderful Wednesdays

Our monthly webinar explores examples of innovative data visualisations relevant to our day to day work. Each month a new dataset is provided from a clinical trial or other relevant example, and participants are invited to submit a graphic that communicates interesting and relevant characteristics of the data.

PSI Book Club

PSI are starting a book club! We will be reading/discussing non-technical books relevant to our roles. Participants will be split into smaller groups to network with each other and practice exercises.

PSI Training Course: Use of Historical Data in Clinical Trials: An Evidence Synthesis Approach

In this short course, we will provide a statistical framework to incorporate external information into a trial. Bayesian Dynamic Borrowing designs based on the meta-analytic predictive (MAP) model will be detailed, and a practice session will be proposed with applications using the R package RBesT.

PSI Medical Statistics Careers Event

Our annual PSI Medical Statistics Careers Event, will be held online on Wednesday 2nd March 2022. The event will include a live online panel discussion and a virtual exhibition session.
