METTL9 and neurodegenerative disease: In conclusion, elucidating the relationship between METTL9 and Golgi function in mammalian neurogenesis will help understanding the cellular and molecular mechanisms underlying Golgi integrity and homeostasis; this, in turn, might be leveraged to amend Golgi fragmentation and dysfunction and represent an important step forward, towards the treatment of both neurodevelopmental and neurodegenerative diseases.
