Identification of TBX3 and shared HAND2-TBX3 target genes in early mouse limb buds [ChIP-seq]
ChIP-seq is combined with RNA-seq analysis to identify the TBX3 and HAND2 target genes during mouse limb bud development. This analysis identifies the DEGs and direct transcriptional targets of HAND2 and TBX3 during the early determinative period critical to establishment of limb axis polarity and the SHH signaling center in the posterior limb bud mesenchyme. In particular, bioinformatics analysis identifies the target gene networks that are co-regulated by both TBX3 and HAND2 transcription factors in the limb bud mesenchyme. A significant fraction of the target genes identified are required for normal limb bud development and their spatio-temporal expression patterns are changed in mutant limb buds at early stages.
