MyoD is a critical myogenic factor induced rapidly upon activation of quiescent satellite cells, and required for their differentiation during muscle regeneration. One of the two enhancers of MyoD, the distal regulatory region, is essential for MyoD expression in postnatal muscle. This enhancer contains a functional divergent serum response factor (SRF)-binding CArG element required for MyoD ex...

Abstract Natural killer (NK) cells are critical for the first line of defense against viral infection and malignancy. While transcriptional epigenetic regulation activated NK is well characterized in mice, these processes not yet fully understood human cells. We performed a targeted CRISPR/Cas9 ribonucleoprotein (RNP) transcription factor screen mature primary to identify putative factors requi...

Myocyte enhancer factor 2 (MEF2) is in the MADS (MCM1agamous-deficiens-serum response factor) family of transcription factors. Although MEF2 is known as a myogenic factor, the expression pattern of the MEF2 family of genes (MEF2A-D) in developing brain also suggests a role in neurogenesis. Here we show that transfection with MEF2C, the predominant form in mammalian cerebral cortex, induces a mi...

Transcription of the gene encoding brain-derived neurotropic factor (BDNF) is induced in response to a wide variety of extracellular stimuli via the activation of a complex array of transcription factors. However, to what degree individual transcription factors confer specificity upon the regulation of Bdnf is poorly understood. Previous studies have shown that members of the myocyte enhancer f...
