combinatorial histone methylation patterns

[LouDore]

There was a paper in the past few years that looked at dozens of distinct histone modifications (methylations & acetylations) in a mammalian cell type by ChIP-Seq, then defined some of the most common combinations and drew conclusions about what functions those specific combinations may be responsible for based on location relative to genes, etc...

I can't remember any more info about the paper, but I KNOW I read a paper like that and wasn't just dreaming...but I can't seem to find it anywhere among my papers or after an hour searching pubmed and google.

Does anybody know what I'm talking about? Can you point me to a reference if you think you know?

Thanks,
Lou

Moving to Epigenetics!

Perhaps one of the ChromaSig papers?

[ffinkernagel]

Was it
Wang et al, "Combinatorial patterns of histone acetylations and methylations in the human genome"

http://www.nature.com/ng/journal/v40/n7/full/ng.154.html

or perhaps
Cui et al, "Chromatin Signatures in Multipotent Human Hematopoietic Stem Cells Indicate the Fate of Bivalent Genes during Differentiation"

http://www.cell.com/cell-stem-cell/retrieve/pii/S1934590908005821

I came across this paper last summer.
Christoph Bock and Thomas Lengauer "Computational epigenetics"

It's not mammalian, but could you be thinking about the 'chromatin colors' paper in drosophila? It's worth reading even if this wasn't what you were remembering.

Was looking through Ernst et al today from the recent issue of Nature and saw the chromatin state table in Fig 1b and knew I had finally found what I was searching for...

The style of the table was so similar to the image I had in my mind that I was searching for when I started this thread. Anyway, this led me to the Nature Biotechnology paper from Ernst & Kellis in Aug 2010 which is exactly what I've been looking for.

Thanks for all the suggestions, everybody -- all very interesting and I hadn't come across 1 or 2 of them during my extensive searching.
