MYC is a target of the Wnt signalling pathway and governs numerous cellular developmental programmes hijacked in cancers. The amplification frequently occurring genetic alteration cancer genomes, this transcription factor implicated metabolic reprogramming, cell death, angiogenesis In review, we analyse gene networks solid We investigate interaction with long non-coding RNAs (lncRNAs). Furtherm...
We demonstrate that c-myc gene expression is essential for growth of breast cancer cells. It also plays an important role in the progression of human breast cancer. c-myc gene amplification may be important for cancer cell invasion, but perhaps not essential for nodal metastasis. We also provide compelling evidence that the c-myc oncogene is an estrogen target gene in hormone-responsive breast ...
Chromosomal translocations affecting the MYC oncogene are the biological hallmark of Burkitt lymphomas but also occur in a subset of other mature B-cell lymphomas. If accompanied by a chromosomal break targeting the BCL2 and/or BCL6 oncogene these MYC translocation-positive (MYC(+)) lymphomas are called double-hit lymphomas, otherwise the term single-hit lymphomas is applied. In order to charac...
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...
A tumorigenic human hepatoma cell line, Hep G2, has been shown to have high steady-state levels of c-myc transcripts compared to normal human liver. We have now characterized c-myc expression in Hep G2 cells with regard to message stability, gene rearrangements, gene amplification, chromosomal translocations, promoter utilization, and the effects of protein synthesis inhibitors. We have determi...
The presence and distribution of N-myc gene product were studied in 13 neuroblastomas and five ganglioneuroblastomas, using immunohistochemical techniques. Nine tumors (eight neuroblastomas and one ganglioneuroblastoma of composite type) contained neuroblastoma cells with positive nuclei for N-myc protein. Microscopic examination showed that most of the positive neuroblastoma cells seemed to be...
Background: Overexpression of the c-MYC oncogene (hereafter MYC) was implicated to suppress tumor immune surveillance and shown associate with poor clinical outcome in several malignancies. Here, we investigated its impact on anti-tumor effect antibody T-cell based immunotherapies diffuse large B-cell lymphoma (DLBCL), Burkitt (BL) multiple myeloma (MM). Methods: Using CRISPR-Cas9 gene editing ...
MYC alterations influence the survival of patients with diffuse large B-cell lymphoma. Most studies have focused on MYC translocations but there is little information regarding the impact of numerical alterations and protein expression. We analyzed the genetic alterations and protein expression of MYC, BCL2, BCL6, and MALT1 in 219 cases of diffuse large B-cell lymphoma. MYC rearrangement occurr...
We hybridized Raji Burkitt lymphoma cells, which carry a t(8;14) chromosome translocation, with human lymphoblastoid cells to study the expression of the translocated cellular myc oncogene (c-myc) in the hybrid cells. In Raji cells the c-myc oncogene is translocated to a switch region of the y heavy chain locus (Sy). Because of sequence alterations in the 5' exon of the translocated c-myc oncog...
ژن c-myc نقش مهمی را در تنظیم رشد و تکثیر سلولی ایفا می کند و بیان بیش از حد این ژن در گستره وسیعی از سرطان های انسانی دیده شده است. حدود 90% رونویسی این ژن از طریق یک توالی 27 نوکلئوتیدی غنی از گوانین بسیار حساس به نوکلئاز بنام nuclease-hypersensitive element iii1 (nhe iii1) کنترل می شود که این توالی قادر به تشکیل ساختار g-quadruplex تحت شرایط فیزیولوژیک است. بنابراین dna ژن c-myc یک هدف بسیار...
