OTX2 represses myogenic and neuronal differentiation in medulloblastoma cells.

The brain development transcription factor OTX2 is overexpressed and/or genomically amplified in most medulloblastomas, but the mechanistic basis for its contributions in this setting are not understood. In this study, we identified OTX2 as a transcriptional repressor and a gatekeeper of myogenic and neuronal differentiation in medulloblastoma cells. OTX2 binds to the MyoD1 core enhancer throug...

CAMP-dependent Protein Kinase Represses Myogenic Differentiation

Myf-5 and MyoD are members of a family of musclespecific basic helix-loop-helix (bHLH) proteins that are fundamental for myogenic cell differentiation and transcriptional activation of muscle-specific genes. Here we report that elevated levels of the intracellular signaling molecule CAMP and overexpression of CAMP-dependent protein kinase (PKA) inhibit myogenic differentiation. PKA represses...

Medulloblastoma with myogenic differentiation: a rare medulloblastoma variant in a young child.

To cite: Crawford JR, Levy ML. BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2015212322 DESCRIPTION A 3-year-old girl presented with a 3-week history of headaches, unsteady gait and episodic vomiting. On neurological examination, she had gaze-evoked nystagmus, intermittent titubation and mild ataxic gait. MRI revealed a large posterior fossa tumour with reduced ...

Histone methyltransferase Suv39h1 represses MyoD-stimulated myogenic differentiation.

Suv39h1 is a histone H3 lysine-9 (H3-K9) specific methyltransferase (HMT) that is associated with gene silencing through chromatin modification. The transition from proliferation into differentiation of muscle cell is accompanied by transcriptional activation of previously silent muscle genes. I report Suv39h1 interaction with myogenic regulator MyoD in proliferating muscle cells and its HMT ac...
