Profiling of Sox9-related genes in chondrogenesis using Sox9-3'EGFP knock-in and Sox9-EGFP/EGFP null chimeric mouse embryos

ABSTRACT: To define the repertoire of Sox9-dependent genes that contribute to the regulation of chondrogenesis, we generated Sox9-3'enhanced green fluorescent protein (EGFP) knock-in mice (Sox9-3'EGFP) and Sox9-EGFP/EGFP null chimeras. EGFP-positive cells of Sox9-3'EGFP knock-in and Sox9-EGFP/EGFP null chimeric embryos harvested from limb buds at embryonic day 12.5 were sorted using a FACSAria flow cytometer (Becton-Dickinson). Total RNA of sorted cells was extracted using the RNeasy Mini Kit (QIAGEN) and amplified according to the instructions provided by Affymetrix. Microarray analysis using the Affymetrix Mouse Genome 430 2.0 Array was performed according to the manufacturer's instructions.

Sox9 is a direct transcriptional activator of cartilage-specific extracellular matrix genes and has essential roles in chondrogenesis. Mutations in or around the SOX9 gene cause campomelic dysplasia or Pierre Robin Sequence. However, Sox9-dependent transcriptional control in chondrogenesis remains largely unknown. Here we identify Wwp2 as a direct target of Sox9. Wwp2 interacts physically with Sox9 and is associated with Sox9 transcriptional activity via its nuclear translocation. A yeast two-hy  ...[more]
