LSD1 and LSD2 histone demethylases are implicated in a number of physiological and pathological processes, ranging from tumorigenesis to herpes virus infection. A comprehensive structural, biochemical, and cellular study is presented here to probe the potential of these enzymes for epigenetic therapies. This approach employs tranylcypromine as a chemical(More)
It is well established that epigenetic modulation of genome accessibility in chromatin occurs during biological processes. Here we describe a method based on restriction enzymes and next-generation sequencing for identifying accessible DNA elements using a small amount of starting material, and use it to examine myeloid differentiation of primary human(More)
Although epigenetic drugs have been approved for use in selected malignancies, there is significant need for a better understanding of their mechanism of action. Here, we study the action of a clinically approved DNA-methyltransferase inhibitor - decitabine (DAC) - in acute myeloid leukemia (AML) cells. At low doses, DAC treatment induced apoptosis of NB4(More)
Chromatin accessibility plays a key role in regulating cell type specific gene expression during hematopoiesis but has also been suggested to be aberrantly regulated during leukemogenesis. To understand the leukemogenic chromatin signature, we analyzed acute promyelocytic leukemia, a subtype of leukemia characterized by the expression of RARα-fusion(More)

Novel drugs are designed against specific molecular targets, but almost unavoidably they bind non-targets, which can cause additional biological effects that may result in increased activity or, more frequently, undesired toxicity. Chemical proteomics is an ideal approach for the systematic identification of drug targets and off-targets, allowing unbiased(More)
