MEIS1 ChIP-seq identifies genes regulating MK and PLT biology. (A) MEIS1 ChIP-seq in CHRF 288-11 cells identifies mainly intronic and intergenic binding sites. (B) Cellular functions of 57 genes with MEIS1 binding events and overexpressed in MKs. Bold represents 6 loci containing sentinel SNPs associated with MPV or PLT count.
