The c-myc gene is the cellular homolog of v-myc, the transforming gene of the MC29 avian leukemia virus (48), and is a member of the myc gene family, which also includes N- and L- myc 1. C-Myc. C-Myc protein is a member of a family of proteins that regulate cell proliferation and apoptosis. The ability of c-myc to regulate apoptotic cell death results from the coordinated activation of c-Myc and several protein partners (such as Max) that facilitate DNA binding and activate transcription

Among its related pathways are Notch Signaling Pathway and Gastric Cancer Network 2 C-jun regulates the transcriptional level of cyclin D1, which is a major Rb kinase. Rb is a growth suppressor, and it is inactivated by phosphorylation. Therefore, c-jun is required for maintaining sufficient cyclin D1 kinase activity and allowing cell cycle progression Function: MYC functions as a transcriptional regulator, capable to induce or repress the expression of a large number of genes, which are thought to mediate its biological functions (Adhikary and Eilers 2005). MYC protein cannot form homodimers, but it binds to MAX that is an obligate heterodimeric partner for MYC in mediating its functions Recently, the c-Myc protein was found to heterodimerize with Max, a protein that cooperates with c-Myc to bind specifically to a core DNA sequence, CAC(G/A)TG. These characteristics suggest that c-Myc participates in the regulation of gene transcription in normal and neoplastic cells.— Kato, G. J.; Dang, C. V. Function of the c-Myc oncoprotein

Translocations involving c- myc and c- myc function Oncogen

  1. Abstract. c-Myc dysregulation is one of the most common abnormalities found in human cancer. MicroRNAs (miRNAs) are functionally intertwined with the c-Myc network as multiple miRNAs are regulated by c-Myc, while others directly suppress c-Myc expression. In this work, we identified miR-33b as a primate-specific negative regulator of c-Myc

In this study, we show that c-Myc expression is induced by many cellular insults, including cisplatin, doxorubicin, paclitaxel, 5-flourouracil, H 2 O 2, and radiation, and the enhanced expression of c-Myc protects against cell death caused by these.

Thus, it seems that an 'old' tRNA synthetase evolved to function as a 'new' and essential antagonist against c-Myc for proper development of the advanced closed circulatory system of vertebrates. A critical component of the c-Myc-antagonizing role of SerRS is the recruitment of SIRT2 Members of the Mad family of basic-helix-loop-helix-leucine zipper proteins inhibit the transcriptional activity of the c-Myc oncoprotein. Mmip-2/Rnf-17 is a RING-finger protein that interacts with all four known Mad proteins, redistributes them to the cytoplasm, and thus enhances c-Myc function. We generated cell lines in which Mmip-2/Rnf-17 was rendered glucocorticoid (GC)-inducible

title: c-Myc exerts a protective function through ornithine decarboxylase against cellular insults, doi: 10.1124/mol.62.6.1400, category: Article menu About Yonsei University Medical Librar c-Myc enhanced reprogramming efficiency of HUMSCs to HLCs. Direct reprogramming of human fibroblasts into hepatocytes was firstly reported to be successfully inducted by FOXA3, HNF1A, and HNF4A [].Considering the limited proliferative ability and difficulty in acquiring large numbers of human fibroblasts, we wished to generate functional HLCs from HUMSCs, because of their easy accessibility. We report in this article that c-Myc-mediated repression of lncRNA IDH1-AS1 sustains activation of the Warburg effect by HIF1α under normoxic conditions. IDH1-AS1 would otherwise enhance IDH1 enzymatic activity through promoting its homodimerization, leading to increased production of α-KG, which, along with decreases in ROS levels similarly resulting from increased IDH1 activity, causes. As one of the most important oncogenes, c-Myc is activated in over half of human cancers. The oncogenic function of c-Myc has been largely attributed to its intrinsic nature as a master transcription factor. Dysregulation of long noncoding RNAs (lncRNAs) has been implicated in a variety of human diseases, including cancer

The c-Myc protein (or Myc) is a transcription factor that positively or negatively regulates expression of distinct sets of target genes. Transcriptional activation by Myc is mediated through dimerization with Max and binding to the DNA consensus sequence CA(C/T)GTG (the E-box) The transcription factor c-Myc is a member of the basic helix-loop-helix leucinezipper (bHLHZip) protein family. The target genes of the c-MYC protein participate in different cellular functions, including cell cycle, survival, protein synthesis, cell adhesion, and micro-RNA expression. c-Myc is also one of the four factors used in reprogramming somatic cells to induce pluripotent stem (iPS.

Oncogene-encoded proteins c-Myc, n-Myc, and l-Myc function in cell proliferation, differentation and neoplastic disease. A mutated version of Myc is found in many cancers, which causes Myc to be constitutively expressed. This leads to the unregulated expression of many genes, some of which are involved in cell proliferation, and result in the formation of cancer. c-Myc antibody is a. General Functions of C-myc. C-myc is used in cell cycle entry, proliferation, and differentiation. C-myc also helps to bind DNA which activates transcription. The c-myc lives a very short life. It is controlled by the level and temporal pattern of expression of their corresponding gene. Without C-myc an organism is unable to survive since there. We report ~450 putative VCP substrates, many of which function in nuclear processes, including gene expression, DNA repair and cell cycle. Moreover, we identify that VCP regulates the level and activity of the transcription factor c-Myc c-Myc (v-myc avian myelocytomatosis viral oncogene homolog) is a transcription factor, which is coded by MYC gene.

In contrast, c-Myc's ability to repress transcription was unaffected by p19(Arf), and c-Myc-mediated apoptosis was enhanced. These differential effects of p19(Arf) on c-Myc function suggested that separate molecular mechanisms mediate c-Myc-induced hyperproliferation and apoptosis Oncogene-encoded proteins c-myc, N-myc, and L-myc function in cell proliferation, differentiation and neoplastic disease.
