RIP-chip by array of RNA-binding protein HuR in mouse early peripheral nerves

ABSTRACT: Identify mRNA targets of the RNA-binding protein HuR in vivo during Schwann cell development using RIP-chip analysis. IP protocol of endogenous mRNA-transfected HuR complexes was performed as described in Keene et al. (2006). In brief, 500 mg of whole-cell lysate obtained from a pool of NB or P5 sciatic nerves from C57BL6J mice were incubated with a suspension of Protein Sepharose beads (Sigma-Aldrich), pre-coated with 15 mg of either IgG1 (BD Pharmingen) or anti-HuR (Santa Cruz Biotechnology) antibodies. mRNAs were isolated using the phenol-chloroform method.

An important prerequisite to myelination in peripheral nerves is the establishment of one-to-one relationships between axons and Schwann cells. This patterning event depends on immature Schwann cell proliferation, apoptosis, and morphogenesis, which are governed by coordinated changes in gene expression. Here, we found that the RNA-binding protein human antigen R (HuR) was highly expressed in immature Schwann cells, where genome-wide identification of its target mRNAs in vivo in mouse sciatic ne  ...[more]
