The gracile axonal dystrophy (gad) mice are known to have a deletion within the gene encoding
ubiquitin carboxy-terminal hydrolase
-1 (Uch-L1) and show hereditary sensory deterioration and motor
paresis
. Expression of Uch-L1 is reported to be almost limited to the nervous system and testis. To understand whether Uch-L1, one of the major
ubiquitin carboxy-terminal hydrolase
(UCH) isozymes in the testis, affects spermatogenesis and other UCH isozymes (Uch-L3, L4 and L5) expression in the testis, we compared the testis between gad, hetero and wild type mice by histological, immunohistochemical analyses and RT-PCR. Histological analysis in 25-week-old gad mice showed shrinking of seminiferous tubules, decreasing total number of cells and enlargement of remaining cells in seminiferous tubules. By immunohistochemistry, a significant decrease (p < 0.05) in the number of proliferating cell nuclear antigen (PCNA) positive cells was observed. Expression of other UCH isozyme mRNAs was not apparently affected by Uch-L1 deficiency in 25-week-old gad mice. This study is the first report on the testis of gad mutant mouse.
