(Submitter supplied) Very little is known on the nature of epigenetic states in developing zebrafish despite its growing importance as a model organism in developmental biology. We report histone modifications on promoters of pluripotency genes in zebrafish embryos at the mid-late blastula transition (MBT+) stage. We identify three classes of expressed genes based on these profiles: (1) those with a promoter occupied by marks of active genes without any repressive marks; (2) those co-occupied by both activating and repressive modifications; of these genes, klf4 was notably found to be mosaically expressed in the embryo, possibly accounting for this epigenetic pattern; (3) those occupied by repressive marks with, surprisingly, little not acetylated H3K9 or H4. more...

(Submitter supplied) Arrays of this design have barcodes that begin with 16021643 or 2521643. Orientation: Features are numbered numbered Left-to-Right, Top-to-Bottom as scanned by an Agilent scanner (barcode on the left, DNA on the back surface, scanned through the glass), matching the FeatureNum output from Agilent's Feature Extraction software." This is the PROBE NAME version of the array Protocol: see manufacturer's web site at http://www.agilent.com/
