Muscle-specific conditional Ulk1 deficiency blunts functional muscle regeneration following I/R. A: quantification of gastrocnemius muscle mass and body mass for MKO and littermate WT mice at day 14 postinjury. B: torque frequency analysis of plantar flexors relative to WT Con. Mass and torque results are represented as means ± SE for n = 5–6 for each genotype/injury. C: quantification of COX4 and Cyt C at day 7 postinjury. All immunoblot results are represented as means ± SE for n = 5–6 for each genotype/injury. D: representative immunoblots of Ulk1, Beclin1, p62, LC3-I, LC3-II, COX4, Cyt C, and 14-3-3 for injured muscles (day 14 postinjury) and Con for MKO mice and littermate WT mice. E: quantification of Beclin1, Ulk1, and total LC3 indicant of autophagy capacity at day 14 postinjury. F: quantification of p62, LC3-II as an index of autophagy flux at day 14 postinjury.
