Aars1sti/ Aars1sti

nervous system
N
• No changes in microtubule levels are found in Purkinje cells
• loss of cells beginning at three weeks of age
• extensive cell loss by six weeks of age especially in rostral cerebellum

behavior/neurological
• mild tremors occur at 6 weeks of age and progress to ataxia
• progressive ataxia
• as demonstrated by rotorod

integument
• patchy hair loss occurs over time
• fur has rough, unkempt, sticky appearance
• electron microscopy indicates short, broken, deformed hair fibers
• hair fibers break at follicular ostium and have cuff of compacted inner root sheath cells
• hyperplasia of outer root sheath
• hair fibers twisted within the follicle

homeostasis/metabolism

cardiovascular system
• ubiquitin puncta are present in about 2.4% of cardiomyocytes
• cardiomyocytes exhibit deposition of protein aggregates that disrupt myofibrillar structure and these protein aggregates occur in prefibrotic hearts
• large vacuoles and a reduction in fiber diameter are often seen in ubiquitin aggregate-containing cardiomyocytes
• mitochondria and sarcoplasmic reticulum are abnormal in cardiomyocytes
• abnormal mitochondria in cardiomyocytes
• myofiber disarray in the ventricular myocardium of hearts
• heart is smaller than in single homozygous Aarssti mice
• hearts exhibit a slight, but significant, reduction in the thickness of the left ventricular posterior wall
• extensive cardiac fibrosis is seen at 4 and 10 months of age
• interstitial and perivascular fibrosis in the left and right ventricular walls and in the interventricular septum
• in the left and right ventricular walls and in the interventricular septum
• less systolic thickening of the left ventricle, indicating myocardial dysfunction
• ventricular output, as measured by the ejection fraction and fractional shortening of the left ventricle, are reduced
• ejection fraction and fractional shortening of the left ventricle are reduced
• however, ventricular arrhythmias are not seen
• cardiomyocytes exhibit multilamellar bodies indicative of impaired lysosomal degradation

cellular
• abnormal mitochondria in cardiomyocytes
• in the left and right ventricular walls and in the interventricular septum

growth/size/body
• decreased body weight at P21 but not P14
