Manipulation of the Myc Interactome to Enhance Nerve Regeneration in a Murine Model.

Objective: This study was undertaken to explore manipulation of the Myc protein interactome, members of an oncogene group, in enhancing the intrinsic growth of injured peripheral adult postmitotic neurons and the nerves they supply. New approaches to enhance adult neuron growth properties are a key strategy in improving nerve regeneration.

Methods: Expression and impact of Myc interactome members c-Myc, N-Myc, Mad1, and Max were evaluated within naive and "preconditioned" adult sensory neurons and Schwann cells (SCs), using siRNA and transfection of CRISPR/Cas9 or luciferase reporter in vitro.

Neurobiological Opportunities in Diabetic Polyneuropathy.

This review highlights a selection of potential translational directions for the treatment of diabetic polyneuropathy (DPN) currently irreversible and without approved interventions beyond pain management. The list does not include all diabetic targets that have been generated over several decades of research but focuses on newer work. The emphasis is firstly on approaches that support the viability and growth of peripheral neurons and their ability to withstand a barrage of diabetic alterations.
