Elucidation of Theg Gene Role in Spermatogenesis and Characterisation of a Novel Spontaneous Mutation Named “nax” in Mouse
… wurde eine spontane Mutation mit der Bezeichnung nax in den ES-Zellen vorgenommen. Diese Mutation war autosomal-rezessiv. Die nax Mäuse zeigen ein komplettes Ausfallen der Haare nach der Geburt und zeigen eine Wachstumsretardierung im Laufe der Entwicklung. Ein ataxiähnlicher Phänotyp wurde am Tag …

The study of sonic hedgehog signaling pathway in the development of lysosomal acid phosphatase (Acp2) mutant mice cerebellar granule cells
… phosphatase 2 (Acp2) mutant mouse (naked-ataxia, nax) shows severe cerebellar cortex defect with a significant reduction in granule cells in the cerebellum. The sonic hedgehog (SHH) and N-Myc pathways are important for granule cell precursor proliferation and differentiation. The project tests the …
