Col3a1 mouse models. Only original references are provided except in case whereby there is some debate regarding the nature of the mutation.
Model | Genotype-Method | Phenotype | Reference |
---|---|---|---|
Col3a1−/− | Targeted deletion Col3a1 promoter and exon 1 | 5% survival after birth, major skin lesions, vascular rupture, abnormal fibril organization. | [53] |
Col3a1+/− | Mild phenotype, normal life span, aortic lesions, reduced collagen III, elevated MMP9 levels. | [55] | |
Col3a1+/− (Col3a1m1Lsmi/+) | Targeted deletion (Col3a1 promoter and exon 1–39)- in frame deletion exon 33–39 upon subsequent analysis. | Mild phenotype, aortic dissection, reduced collagen III. 30% lethality at 3 month | [56] |
Col3a1Tg-G182S/+ | Overexpression of Col3a1 transgene harbouring glycine substitution (Gly182Ser) | Thin and fragile skin, open wounds, vascular fragility, reduced collagen III, abnormal fibril organization | [57], [58] |
Col3a1G209S/+ | CRISPR glycine substitution | Vascular phenotype, sudden death due to aortic rupture, abnormal fibril organization, median survival 400 days | [51] |
Col3a1G938D/+ | CRISPR glycine substitution | Vascular phenotype, sudden death due to aortic rupture, abnormal fibril organization, median survival 45 days. | [51] |
Tsk2/+ (Col3a1 C33S/+) | ENU mutagenesis, missense mutation in N-terminal propeptide | Tight skin (increased ECM deposition), thick collagen fibrils, model of systemic sclerosis | [60] |
