Zfp423 binds autoregulatory sites in p19 cell culture model.

Zfp423 is a 30 zinc finger transcription factor that forms regulatory complexes with EBF family members and factors targeted by canonical signaling pathways. Zfp423 mutations produce a range of developmental abnormalities in mice and humans related to the ciliopathies. Surprisingly, computational analysis of clustered Zfp423 and partner motifs in conserved genomic sequences predicts enrichment in Zfp423 and Ebf genes.

An ancestral variant of Secretogranin II confers regulation by PHOX2 transcription factors and association with hypertension.

Granins regulate secretory vesicle formation in neuroendocrine cells and granin-derived peptides are co-released with neurotransmitters as modulatory signals at sympathetic sites. We report evidence for association between a regulatory polymorphism in Secretogranin II (SCG2) and hypertension in African-American subjects. The minor allele is ancestral in the human lineage and is associated with disease risk in two case-control studies and with elevated blood pressure in a separate familial study.

Zfp423 controls proliferation and differentiation of neural precursors in cerebellar vermis formation.

Neural stem cells and progenitors in the developing brain must choose between proliferation with renewal and differentiation. Defects in navigating this choice can result in malformations or cancers, but the genetic mechanisms that shape this choice are not fully understood. We show by positional cloning that the 30-zinc finger transcription factor Zfp423 (OAZ) is required for patterning the development of neuronal and glial precursors in the developing brain, particularly in midline structures.

ROR alpha in genetic control of cerebellum development: 50 staggering years.

The staggerer mutation was first identified at the Jackson Laboratory in 1955. In the ensuing half-century, studies of staggerer mice have provided new insights into developmental neurobiology, gene regulatory networks, and circadian behavior. Recent work has expanded the role of RORalpha, the transcription factor mutated in staggerer, to peripheral tissues, including cholesterol and lipid metabolism, immune function, and bone development.
