Enhancement of Heme-Oxygenase 1 in the Injured Peripheral Nerve Following Sulforaphane Administration Fosters Regeneration via Proliferation and Maintenance of Repair Schwann Cells.

ABSTRACT: Nuclear erythroid 2-related factor 2 (Nrf2) and its downstream effector heme oxygenase 1 (HO-1) are commonly activated in response to cellular stresses. The elevated expression of HO-1 has been associated with markedly accelerated peripheral nerve regeneration. This study aimed to evaluate the impact of a naturally occurring dietary Nrf2/HO-1 activator-sulforaphane (SFN)-on regeneration in a murine sciatic nerve crush model. The beneficial safety profile of SFN has been thoroughly investigated and confirmed several times. Here, SFN was administered daily, starting immediately after C57BL/6 mice were subjected to sciatic nerve crush injury. Injured sciatic nerves were excised at various time points post injury for molecular, immunohistochemical and morphometric analyses. Moreover, functiona
