| Genetic information | Exon 2 of Dusp1 gene was disrupted by the insertion of a neomycin selection cassette inserted by homologous recombination. (Dorfman et al. Oncogene. 1996 Sep 5;13(5):925-31). |
| Phenotypic information | Homozygous:Deficient mice are born at normal frequency and are fertile (Dorfman et al., 1996). Dusp1-/- mice exhibited increased inflammatory response and bacterial clearance was impaired in homozygous mice, which displayed increased mortality (Hammer et al., 2010). Dusp1 deficiency accelerates the onset and the progression of age-related hearing loss (Celaya et al., 2019). Dusp1 -/- mice exhibited premature and progressive sensorineural hearing loss, with total deafness by age 12 months. Dusp1 deficiency generated a redox imbalance in young mice, which increased the levels of reactive oxygen species, leading to DNA damage and cochlear cell loss due to apoptosis. Progressive hearing loss also correlated with inflammatory dysregulation, as Dusp1 deficit increased macrophage infiltration, with an exacerbated cochlear inflammatory response in Dusp1-/- mice (Celaya et al., 2019).Heterozygous:Dusp1 heterozygous mice showed no differences in ABR thresholds when comparing with wild type mice at 8-month-old (Celaya et al., 2019). |
