Description
Pitx1, critical regulator of a limited hindlimb-specific gene network, targets the limb development program common to both fore- and hindlimbs in order to implement hindlimb-specific limb morphology. Overall design: The gene regulatory networks governing forelimb vs. hindlimb development in mouse were investigated using expressing profiling of morphologically stage-matched e10.5 forelimbs and e11.0 hindlimbs, ChIPseq of chromatin marks, and ChIPseq of limb-specific transcription factors Pitx1 and Tbx5. The makeup of the Pitx1-directed components of the hindlimb gene network were investigated using expression profiling of Pitx1 null hindlimbs at two stages (e11.0 and e11.5).

Description
Deployment of a cell-specifying enhancer repertoire by the pioneer factor Pax7 The establishment and maintenance of cell identity depends on implementation of stable cell-specific chromatin landscapes. Pioneer transcription factors establish new cell fate competences by triggering chromatin remodeling during development. Here, we used pituitary cell specification to define the salient features of pioneer action. Comparison of purified pituitary cells of different lineages showed that chromatin accessibility differs at enhancers rather than promoters. The pioneer factor Pax7 specifies one pituitary lineage identity by opening a specific repertoire of enhancers that are distinct from the myogenic targets of Pax7. Pax7 binds its pioneer targets rapidly and days before chromatin remodeling and gene activation. Finally, enhancers opened by Pax7-dependent chromatin remodeling exhibit loss of DNA methylation and they acquire long term epigenetic memory. The present work identifies enhancer pioneering as a critical feature for cell fate specification and maintenance. Overall design: RNA extraction followed by high throughput sequencing (RNA-seq)

Description
The combinatorial expression of the Hox genes along the body axes, referred to as the HOX code, is a major determinant of cell fate and plays a prevailing role in generating the animal body plan. In developing limb buds, the paralogous group 13 genes of the HoxA and HoxD clusters are essential for patterning the distal-most limb structures, the digits. Inactivation of HOXA13 and HOXD13 transcription factors (HOX13) leads to complete digit agenesis in mice, but how HOX13 regulate transcriptional outcomes and confer identity to the distal-most limb cells has remained elusive. Here we performed genome-wide profiling of HOX13 by chromatin immunoprecipitation and analyzed the transcriptome and chromatin state of wild type early and late-distal limb buds, as well as Hoxa13-/-;Hoxd13-/- compound mutant limb buds. Our results show that inactivation of HOX13 impairs the activation and repression of putative cis-regulatory modules specific to the late-distal limb cells. Loss of HOX13 also disrupts the specific, spatial patterning of gene expression along the proximal-distal axis of the developing limb buds. These results show that proper termination of the early limb transcriptional program and activation of the late-distal limb program are coordinated by the dual action of HOX13 on cis-regulatory modules. Overall design: Totla mRNAs from dissected distal parts of e11.5 forelimb, of wild-type as well as Hoxa13-/-;Hoxd13-/- mice
