(KO) of myc genes have provided substantial insight into not only their normal functions during development, but also shed light on their tumorigenic functions when they are misregulated. c-myc and N-myc genes both are essential in neural stem and precursor cells (NSC) for normal mouse brain growth[1, 2]. The fact that mutation of N-myc also causes microcephaly in humans in Feingold Syndrome[3]...

Signal transducer and activator of transcription (STAT) comprises a family of universal transcription factors that help cells sense and respond to environmental signals. STAT5 refers to two highly related proteins, STAT5A and STAT5B, with critical function: their complete deficiency is lethal in mice; in humans, STAT5B deficiency alone leads to endocrine and immunological problems, while STAT5A...

The worst subtype of neuroblastoma is caused by MYCN oncogene amplification and N-Myc oncoprotein over-expression. Long noncoding RNAs (lncRNAs) are emerging as critical regulators of gene expression and tumourigenesis. While Myc oncoproteins are well-known to exert tumourigenic effects by regulating the expression of protein-coding genes and microRNAs, little is known about which lncRNAs are M...

In neuroblastoma LAN-1 cells harboring an amplified MycN gene, disruption of cooperation between Ras and MycN proteins by the Ras inhibitor farnesylthiosalicylic acid (FTS, Salirasib) reportedly arrests cell growth. Our aim was to establish whether this is a general phenomenon. We examined the effects of FTS on gene-expression profiles, growth and death of NCIH929 myeloma cells and K562 leukemi...

Mutations in the gene encoding N-myc downstream-regulated gene-1 (NDRG1) lead to truncations of the encoded protein and are associated with an autosomal recessive demyelinating neuropathy--hereditary motor and sensory neuropathy-Lom. NDRG1 protein is highly expressed in peripheral nerve and is localized in the cytoplasm of myelinating Schwann cells, including the paranodes and Schmidt-Lanterman...

www.impactjournals.com/oncotarget 86 Oncotarget 2010; 1: 86-88 Researchers have been captivated by the myc family of proto-oncogenes and their ability to regulate a diverse array of cellular processes through transcriptional regulation of target genes. Since the early 1980s researchers have worked to understand how Myc family members regulate hundreds of genes in a contextdependent and cell typ...

N-myc downstream regulated gene 1 (NDRG1), also known as differentiation related gene 1, was previously identified as an up-regulated gene upon cellular differentiation. Even though its sequence along with its expressional pattern in cancer cell lines are evident, the functional aspects concerning cell proliferation, viability, differentiation and cell cycle regulation of NDRG1 remains vague. T...

The impact of low temperature on the Korolkov Aronnik plant triggers expression CBF family transcription factors, which, in turn, activate many downstream genes that confer resistance to cold and frost. article will consider identification ICE1 gene (inducer 1 expression) by Korolkov, an upstream factor regulates during cold. A mutation wild blocks CBF3 reduces located CBFs, which leads a signi...

N-Myc downstream-regulated gene 2 (NDRG2) is a candidate tumor suppressor gene, which plays an important role in controlling tumor growth. The aim of this study was to investigate the expression of NDRG2 gene in bladder cancer (BC) tissues and several bladder cancer cell lines, and to seek its clinical and pathological significance. Ninety-seven bladder carcinoma and 15 normal bladder tissue se...

MYCN gene amplification in neuroblastoma drives a gene expression program that correlates strongly with aggressive disease. Mechanistically, trimethylation of histone H3 lysine 4 (H3K4) at target gene promoters is a strict prerequisite for this transcriptional program to be enacted. WDR5 is a histone H3K4 presenter that has been found to have an essential role in H3K4 trimethylation. For this r...
