Cardiomyocyte defect in Nacatm1Dsr/Nacatm1Dsr embryos

mortality/aging
• partial lethality between E10.5 and E12.5
• mice that survive are viable and fertile

cardiovascular system
• decreased and poorly organized at E11.5
• at E11.5
• frequently seen at E11.5
• in about 50% of embryos at E10.5
• decrease in the number of proliferation myocytes in the heart at E10

growth/size/body
• about 50% of embryos show some developmental delay at E10.5
• in males at 3 months of age
• evident in surviving mice by 1 week of age

muscle
• decreased and poorly organized at E11.5
• at E11.5
• in the calf probably as a result of fewer myofibers as the size of individual fibers and number of fibers per cross-sectional area are similar to wild-type controls
• increased death of cultured satellite cells over a 96 h period
• however, no difference in satellite cell proliferation is detected
• decrease in the number of proliferation myocytes in the heart at E10
• impaired regeneration in calf muscles following cardiotoxin induced necrotic damage

embryo
• about 50% of embryos show some developmental delay at E10.5

homeostasis/metabolism
• frequently seen at E11.5
• in about 50% of embryos at E10.5

cellular
• decrease in the number of proliferation myocytes in the heart at E10
