what is mycn amplification neuroblastoma?
148650
A laboratory test in which cells in a sample of tumor tissue or bone marrow are checked to see how many copies of the MYCN gene are in the tumor DNA. MYCN is important for cell growth. Having more than 10 copies of the gene is called MYCN gene amplification.

All you will see on a gel is a smear and it is very difficult to know if this is RNA or DNA. Remember most cDNA reactions only copy RNA roughly 1:1 so you will not see much/any amplification here.

Benign atypical junctional melanocytic hyperplasia is characterized by a proliferation of these large cells along the dermoepidermal junction. They are dispersed at uneven intervals and are too few in number to be considered compound nevi.

Niemann-Pick disease type C (NPC) is a rare progressive genetic disorder characterized by an inability of the body to transport cholesterol and other fatty substances (lipids) inside of cells. This leads to the abnormal accumulation of these substances within various tissues of the body, including brain tissue.

2.7 Chromosome 12. Cyclin dependent kinase 4 (CDK4) facilitates cell cycle progression by regulating RB1. Amplifications of CDK4, like CDK6, are observed in glioblastomas and are often overexpressed (77,104).

Juvenile myoclonic epilepsy is an epilepsy syndrome characterized by myoclonic jerks (quick jerks of the arms or legs), generalized tonic-clonic seizures (GTCSs), and sometimes, absence seizures. The seizures of juvenile myoclonic epilepsy often occur when people first awaken in the morning.

This fast-growing lymphoma accounts for about one third of NHL cases. For this lymphoma, it is typical for lymph nodes to double in size every month, and patients often present within a few months of having noted an enlarged lymph node.

But, like stage 1, there's no evidence that it has spread to nearby lymph nodes or other organs, so it's also considered N0 and M0. As in stage 1, a stage 2 cancerous kidney will probably be removed, and follow-up therapy might not be necessary.

Seizures-scoliosis-macrocephaly syndrome is a rare, genetic neurometabolic disorder characterized by seizures, macrocephaly, delayed motor milestones, moderate intellectual disability, scoliosis with no exostoses, muscular hypotonia present since birth, as well as renal dysfunction.

But in neuroblastoma, they become cancer cells instead. Although neuroblastoma sometimes forms before a child is born, it usually isn't found until later, when the tumor begins to grow and affect the body. When neuroblastoma is found and treated in infancy, the chance of recovery is good.

Abstract. The transcription factor c-Myc strongly stimulates cell proliferation but also regulates apoptosis, senescence, cell competition and cell differentiation, and its elevated activity is a hallmark for human tumorigenesis.
