Abstract

Murine SEL-1L (mSEL-1L), a key component of the endoplasmic reticulum associated degradation (ERAD) pathway, is essential during mouse embryonic development as revealed by multi-organ dysfunction and subsequent in uterus lethality occurring in mSEL-1L knock-outs. mSEL-1L is highly expressed in mouse embryonic stem cells, during neural commitment and in mature stem cells (NSCs) but completely absent during astrocyte, oligodendrocyte and neuron differentiation. Interestingly, mSEL-1L protein depletion in differentiated neural stem cells and in mouse adult brain is partly due to activation of mmu-miR-183, a microRNA able to suppress the expression of stem cell factors. We hypothesize that mSEL-1L is an “embryonic stemness marker” that could influence neurogenesis and gliogenesis cell fate determination by establishing a specific micro-environment that coordinates stem cells self-renewing and differentiation.
