Figure Lengend Snippet: A Schematic diagram of calpeptin administration schedule followed by histological analyses in Slc7a5 fl/fl and Syn1-Cre;Slc7a5 fl/fl mice. B Kaplan–Meier survival analysis of Slc7a5 fl/fl mice and Syn1-Cre;Slc7a5 fl/fl mice treated with vehicle or calpeptin ( Slc7a5 fl/fl mice + vehicle, n = 9; Slc7a5 fl/fl mice + calpeptin, n = 7; Syn1-Cre;Slc7a5 fl/fl mice + vehicle, n = 5; Syn1-Cre;Slc7a5 fl/fl mice + calpeptin, n = 7). C – E Immunofluorescent images and quantitative data of cleaved caspase 3/ChAT/DAPI staining in lumbar spinal cord; ( D ) the number of ChAT positive cells, and ( E ) the number of cleaved caspase 3 and ChAT double positive cells of Slc7a5 fl/fl mice and Syn1-Cre;Slc7a5 fl/fl mice treated with vehicle or calpeptin ( Slc7a5 fl/fl mice + vehicle, n = 5; Slc7a5 fl/fl mice + calpeptin, n = 5; Syn1-Cre;Slc7a5 fl/fl mice + vehicle, n = 5; Syn1-Cre;Slc7a5 fl/fl mice + calpeptin, n = 5). Arrowheads indicate representative cleaved caspase 3, ChAT, and double positive cells. F – I Immunofluorescent images of synaptophysin/neurofilament/BTX staining and quantitative data of NMJ in EDL muscle; ( G ) NMJ area (μm 2 ), ( H ) NMJ maturity (%), and ( I ) NMJ innervation (%) of Slc7a5 fl/fl mice and Syn1-Cre;Slc7a5 fl/fl mice treated with vehicle or calpeptin ( Slc7a5 fl/fl mice + vehicle, n = 5; Slc7a5 fl/fl mice + calpeptin, n = 5; Syn1-Cre;Slc7a5 fl/fl mice + vehicle, n = 5; Syn1-Cre;Slc7a5 fl/fl mice + calpeptin, n = 5). * P < 0.05, ** P < 0.01, *** P < 0.001, and # P < 0.05.
