MYCN

A gene on chromosome 2p24.3 that encodes a DNA-binding transcription factor.
 
Molecular pathology
MYCN mutation causes Feingold syndrome; MYCN is amplified in various tumours, especially in neuroblastomas.

This work has also led to the surprising observation that the N-Myc protein, which drives neuroendocrine tumorigenesis, is stabilized by association with the Aurora-A kinase and that clinically available Aurora-A inhibitors can dissociate the complex and destabilize N-Myc.
Alt proved the generality of his initial discoveries when he showed that the gene n-myc is commonly amplified in the childhood cancer neuroblastoma.
And although the cancer has not spread past the tumour site, the cells show a genetic abnormality called N-MYC Amplification.
The researchers identified two proteins, each linked to different aspects of sleep: phosphorylated dynamin 1 levels were related to how long it took to fall asleep, while phosphorylated N-myc gene 2 protein levels tracked the amount of sleep deprivation and corresponded to the well-known brain wave measure of sleep need.
One 3-month old patient underwent partial cystectomy with negative surgical margins, but had poor-risk prognostic indicators, such as unfavourable Shimeda classification, n-myc amplification and 1p chromosome deletion, with lymph node extension.
The researchers identified two proteins that affected these responses, each linked to different aspects of sleep: phosphorylated dynamin 1 levels were linked to how long it took to fall asleep, while phosphorylated N-myc downstream regulated gene 2 protein levels tracked the amount of sleep deprivation and corresponded to the well-known brain-wave measure of sleep need, they report.

The Myc family of oncoproteins (c-Myc, N-Myc, and L-Myc) regulate critical pathways that contribute to tumors; c-Myc expression, which is activated in human Burkitt lymphoma, is sufficient to induce the growth of several tumor types in animal models.
The contributors share recent findings on cognitive disruption in Angelman syndrome, cultural differences in infantile amnesia, drug-induced neuronal plasticity occurring at excitatory synapses in the brain, and the N-Myc downstream-regulated gene family.

Recently, the Australian team inserted a cell-proliferation gene called N-myc alongside a gene that regulates keratin synthesis in mice.
