Transcriptional start sites for miR-192 and miR-194 which are expressed in all three tissues, but at decreased levels in pancreas where the H3K4me3 region at chr19:6263000 is nearly absent. The ES-cell promoter from (23) does not appear to be active in any of these tissues, but a CpG+ promoter for the Atg2 gene is active and may be the source of these miRNAs in the pancreas.
