H1f6tm1Drab targeted mutation 1, Birgit Drabent MGI:3578782 |
||||||||||||||||||||||||||||
| Summary |
6 genotypes
|
|
|
| ♀ | phenotype observed in females |
| ♂ | phenotype observed in males |
| N | normal phenotype |
|
• homozygous null mice develop normally and exhibit normal testicular morphology, spermatogenesis and fertility, although Hist1h1a (H1.1), Hist1h1c (H1.2) and Hist1h1e (H1.4) gene expression was enhanced during spermatogenesis
|
|
|
| ♀ | phenotype observed in females |
| ♂ | phenotype observed in males |
| N | normal phenotype |
 |
• significant alterations in sperm velocities, beat frequency, amplitude, straightness threshold and forward movement, indicating decreased sperm motility compared to wild-type, however did not observe reduced migration of sperm in the female genital tract
• smaller decrease in sperm motility than seen in triple homozygous Acr/Hist1-1s/Mcsp and Acr/Hist1h1t/Mcsp mice
|
|
|
• significant alterations in sperm velocities, beat frequency, amplitude, straightness threshold and forward movement, indicating decreased sperm motility compared to wild-type, however did not observe reduced migration of sperm in the female genital tract
• smaller decrease in sperm motility than seen in triple homozygous Acr/Hist1-1s/Mcsp and Acr/Hist1h1t/Mcsp mice
|
|
|
• produced no offspring when mated to wild-type females
|
|
• only 8%-15% of wild-type oocytes were fertilized by mutant sperm (compared to 84.8% by wild-type sperm), but 71-75% of the fertilized oocytes developed into normal blastocysts (compared to 61.5% of the controls)
|
|
|
• impaired sperm penetration of zona pellucida from wild-type females
|
|
|
| ♀ | phenotype observed in females |
| ♂ | phenotype observed in males |
| N | normal phenotype |
|
|
| ♀ | phenotype observed in females |
| ♂ | phenotype observed in males |
| N | normal phenotype |
|
|
• fertility of males is reduced to 20%-50% of controls
|
|
|
| ♀ | phenotype observed in females |
| ♂ | phenotype observed in males |
| N | normal phenotype |
|
|
| ♀ | phenotype observed in females |
| ♂ | phenotype observed in males |
| N | normal phenotype |
|
|
• 18% of sperm (compared to 7.7% of wild-type) had abnormal sperm head shapes that were broader and less pointed than wild-type
|
|
|
• reduced number of sperm in oviducts of wild-type females, indicating that migration of sperm through the female genital tract is impaired
|
|
|
• significant alterations in sperm velocities, beat frequency, amplitude, straightness threshold and forward movement, indicating decreased sperm motility compared to wild-type
• greater decrease in sperm motility than in triple homozygous Tnp2/Hist1h1t/Mcsp mice
|
|
|
• litter size was sharply reduced when mutant males were mated to wild-type females
|
|
• only 8%-15% of wild-type oocytes were fertilized by mutant sperm (compared to 84.8% by wild-type sperm), but 71-75% of the fertilized oocytes developed into normal blastocysts (compared to 61.5% of the controls)
|
|
|
• reduced binding of sperm to zona pellucida from wild-type females
|
|
|
• 18% of sperm (compared to 7.7% of wild-type) had abnormal sperm head shapes that were broader and less pointed than wild-type
|
|
|
• reduced number of sperm in oviducts of wild-type females, indicating that migration of sperm through the female genital tract is impaired
|
|
|
• significant alterations in sperm velocities, beat frequency, amplitude, straightness threshold and forward movement, indicating decreased sperm motility compared to wild-type
• greater decrease in sperm motility than in triple homozygous Tnp2/Hist1h1t/Mcsp mice
