Below is a short description of each strain. All mice are on the C57Bl/6J inbred background.
- Cftrtm1Unc (S489X mutation)- Snouwaert et al., 1992.[1] These mice have the S489X mutation and a neomycin cassette within exon 11.
- Cftrtm1Kth (F508del mutation)- Zehier et al., 1995.[2] These mice have the F508del mutation and a neomycin cassette insert between exon 11 and 12.
- Cftrtm2Mrc (R117H mutation)- van Heeckeren et al., 2004. [3] These mice have the R117H mutation in exon 4 and a neomycin cassette insert between exon 4 and 5.
- Cftrtm1Unc Tg(FABPCFTR)1Jaw /Cwr (gut corrected mice with S489X mutation)- Zhou et al, 1994.[4] These mice have the S489X mutation but also express human Cftr from the fatty acid binding protein promoter (FABP). Since this allows for Cftr expression in the intestines, there is very little intestinal obstruction in these CF mice and have been labeled “gut-corrected”. However human CFTR may be expressed elsewhere in the mouse.
- Cftrtm1KthTg(FABPCFTR)1Jaw /Cwr (gut corrected mice with F508del mutation)- crossed Zhou mutation with Cftrtm1Kth.[4, 5] These mice have the F508del mutation but also express human Cftr from the fatty acid binding protein promoter (FABP). Since this allows for Cftr expression in the intestines, there is very little intestinal obstruction in these CF mice and have been labeled “gut-corrected”. However human CFTR may be expressed elsewhere in the mouse
- Cftrtm1.1Cwr (CftrΔ10 Exon 11 deleted)-Hodges et al., 2008. [6] These mice are missing exon 11. This exon is also referred to as exon 10 using legacy exon numbering.
- Cftrtm1Cwr (Cftrfl10Exon 11 conditional) -Hodges et al., 2008. [6] These mice have loxp sites around exon 11 and are conditional. Thus if crossed with Cre expressing mice, exon 11 can be deleted in tissues of interest. This exon is also referred to as exon 10 using legacy exon numbering.
- Cftrtm2Cwr (Cftrinvfl10 Exon 11 inverted conditional) Hodges et al., 2011. [7] These mice have loxp sites around an inverted exon 11 and are conditional. Thus if crossed with Cre expressing mice, exon 11 can be inverted back into the functional form in tissues of interest. This is a restoration of Cftr model. This exon is also referred to as exon 10 using legacy exon numbering.
- Cftrem1Cwr (F508del mutation)- These mice have the ΔF508 mutation created using endonuclease mediated gene editing. This mouse has a milder CF phenotype and similar to Cftrtm1Eur that also contains a F508del. (Manuscript in preparation)
- Cftrem2Cwr (T-insertion or null)- These mice have a T base pair insertion in exon 11 creating a null mutation. This mutation was created using endonuclease mediated gene editing. (Manuscript in preparation)
- Cftrem3Cwr (G542X)- McHugh et al., 2018 [8]These mice have the G542X mutation created using endonuclease mediated gene editing.
