mice expressing the enzyme systemically have rough and flaky skin which becomes detectable around 5 days after birth and becomes obscure by 2 weeks after birth. In transgenic mice, proliferating keratinocytes increase approximately 3fold in epidermis compared to wild-type. In transgenic epidermis, the expression domain of cytokeratin 14 increases from 1-2 layers to 4-5 layers and co-expresses with cytokeratin 6 and 10 in the upper layers. Transgenic mice also show delayed development of the barrier function around 8 days postnatal, and acquire the function by 12 days postnatal |

transgenic expression of enzyme in mouse results in dramaitc reduction in the expression of the alphaGal epitope. Mice show abnormal phenotypes, such as occasional death immediately after birth, growth retardation, and transient skin lesions |
