N normal phenotype
behavior/neurological
• in a forced-swim test, female mice exhibit less immobility compared with wild-type mice but as much as in Clockm1Jt homozygotes
• however, anxiety and depressive-like behavior are not increased
• during constant darkness in an open field, mice spend more time exploring the center than wild-type mice but as much as in Clockm1Jt homozygotes
• in female mice in an open field test
• circadian period gradually lengthens over the first 39 days of constant darkness, with an average of 24.4 hours compared to 23.2 hours in wild-type (J:18005)
• increased 0.6 hr upon exposure to constant darkness (J:198519)
• Background Sensitivity: mice on a C57BL/6J isogenic background exhibit a longer activity period under constant darkness than mice on a (BALB/cJ x C57BL/6J)F1 or BALB/cJ congenic background (J:198519)
• in constant darkness, mice exhibit a 1 hour increase in free-running rhythm of locomotor activity compared with wild-type mice
• mice spend 9% less time asleep during the entire 24 hour light dark cycle compared with wild-type mice
• during the 12 hour dark phase, mice spend less time in non-REM sleep than wild-type mice
• during the 12 hour dark phase, REM sleep is shorter than in wild-type mice

homeostasis/metabolism
• mice exhibit decreased plasminogen activator inhibitor-1 (PAI-1) levels compared with wild-type mice
• at zeitgeber time (ZT) 14, mice fail to exhibit a decreased in total plasma tissue plasminogen activator (tPA) levels compared with wild-type mice
• diurnal variations in time to thrombotic vascular occlusion (TTVO) subsequent to photochemical injury observed in similarly treated wild-type mice
• TTVO subsequent to photochemical injury is increased at zeitgeber time (ZT) 14 compared with similarly treated wild-type mice
