Preclinical committee

Aims

Writing

The Committee for Preclinical Research strives to establish common protocols for (pre)clinical research, thereby harmonizing and standardizing the worldwide efforts to investigate Down syndrome, thus enabling better comparisons between studies across the globe.

The Committee is pursuing its objectives to help standardise high quality preclinical research into Down syndrome, including by facilitating access to important resources, and helping provide essential robust data for those resources including controls.

Preclinical Committee

Activities

  • Human cell lines

    Committee member Anita Bhattacharyya has been diligently pursuing different possible repositories for human induced pluripotent stem cells (iPSCs) and for human fibroblast cell lines. Ideally, we would like to have one ‘go to’ repository for DS resources internationally. Factors to consider are what each repository is prepared to bank, and cost to researchers. We would like to include unpublished data if possible, and protocols. We aim to have some preliminary recommendations for discussion by the wider T21RS community later in 2020. Also, for discussion are options to help fund such a DS and control cell line bank.

  • Mouse models

    The 2018 spreadsheet of all published chromosomal models is available to all T21RS members and this includes simplified ‘lab names’ that can be used in papers after stating the full correct name as held by the Mouse Nomenclature Committee (see Downloads).

    We will review updates likely in late 2020, noting new rodent strains may be published later in 2020/2021.

    Establishing common protocols for preclinical research: behavioural analysis, cellular characterisation, breeding schemes and rigorous reporting of genetic and environmental details for Down syndrome models.

    The preclinical committee has recommendations for how papers should report mouse experiments on DS research. These include:

    1. T21RS members will have information available about the ARRIVE (Animal Research: Reporting of In Vivo Experiments) guidelines to improve the reporting of research using animals – maximizing information published and minimizing unnecessary studies.
    2. defining each mouse strain by its official MGI (Mouse Genome Informatics) name, which is unique and available from the MGI website (www.informatics.jax.org).

    Randall Roper, Mara Dierssen, Yann Herault created a checklist specifically for reporting DS mouse model research; these are based on the ARRIVE guidelines with extras important specifically for DS research. We will circulate these ‘rules’ to T21RS for discussion in 2020 and then to finalise and publish.

  • Training the next generation of DS researchers

    We wish to bring early stage researchers onto the T21RS Preclinical Committee, in order to gain ‘managerial’ experience of working with the T21RS community. We have issued an invitation for junior PIs/postdocs to apply to us for a one-year membership of the committee. Two Members will be chosen by summer 2020.
