Previously, we reported that Atg5-null mice are neonatal lethal; however, the exact cause of their death remains unknown. Here, we show that restoration of ATG5 in the brain is sufficient to rescue Atg5-null mice from neonatal lethality. This suggests that neuronal dysfunction, including suckling failure, is the primary cause of the death of Atg5-null neonates, which would further be accelerated by nutrient insufficiency due to a systemic failure in autophagy. The rescued Atg5-null mouse model, as a resource, allows us to investigate the physiological roles of autophagy in the whole body after the neonatal period. These rescued mice demonstrate previously unappreciated abnormalities such as hypogonadism and iron-deficiency anemia. These observations provide new insights into the physiological roles of the autophagy factor ATG5.}, pages = {116--130}, title = {Systemic Analysis of Atg5-Null Mice Rescued from Neonatal Lethality by Transgenic ATG5 Expression in Neurons.}, volume = {39}, year = {2016} }
