  2. Resource Description
    "These targeted mutation mice exhibit a loss of both behavioral and molecular circadian rhythms. When placed in constant darkness, the mice undergo an immediate loss of circadian rhythmicity. Locomotor activity is impaired in both light and constant dark cycles. Reduced total activity is seen as the mice age. They display a progressive noninflammatory arthropathy. Little pathology is seen prior to 11 weeks of age, but virtually all homozygotes develop joint ankylosis due to flowing ossification of ligaments and tendons by 35 weeks of age. Bone density and articular cartilage are unaffected. Inactivation of the gene suppresses diurnal variation in glucose and triglycerides. Gluconeogenesis is abolished in homozygotes, but the counterregulatory response of corticosterone and glucagon to insulin-induced hypoglycemia is retained. Homozygotes are viable but not fertile and have an increased mortality rate after 26 weeks of age. A truncated, non-functional protein is produced. This strain may be useful in studies of circadian rhythm, arthritis, ankylosis, and glucose homeostasis. "
