Many oncogenic signaling pathways target the translation initiation stage to satisfy the increased anabolic demands of cancer cells. Using quantitative profiling of initiating ribosomes, we found that ribosomal pausing at the start codon serves as a “brake” to restrain the translational output. In response to oncogenic 2011-11-11 · In principle, cancer cells evade genomic instability-induced apoptosis and acquire aggressive phenotype by up-regulating survival signaling pathways, the so-called oncogenic addiction , which is manifested by sharp differences in the activation status of mTOR, p70S6K, Akt, and GSK3β between MDA-MB-231 cells and MCF-10A cells (Fig. 2A). 2010-11-13 · Oncogenic KRAS modulates mitochondrial metabolism in human colon cancer cells by inducing HIF-1α and HIF-2α target genes.

These linkages are mediated by various oncogenic molecules and signals, such as c-Myc, p53, and the insulin/Ras pathway. Furthermore, several regulators of glycolysis have been recently identified as oncogene candidates, including the hypoxia-inducible factor pathway, sirtuins, adenosine monophosphate-activated kinase, glycolytic pyruvate kinase M2, phosphoglycerate mutase, and oncometabolites. The adenosine A2b receptor (A2bR) was considered to play an oncogenic role in many human malignancies. However, the expression and molecular function of A2bR in bladder urothelial carcinoma (BUC) have not been well elucidated. Herein, we found that the expression of A2bR was higher than other adenosine receptors in Background: Adenosine deaminases acting on RNA (ADARs) are involved in adenosine-to-inosine (A-to-I) editing and implicated in tumorigenesis and prognosis.

Chun SY (1), Johnson C, Washburn JG, Cruz-Correa MR, Dang DT, Dang LH. Author information: (1)University of Michigan Comprehensive Cancer Center, Ann Arbor, MI, USA. 2021-04-04 · The regulation of oncogenic signaling pathways by the m6A modification and its regulators also render them as potential druggable targets for the treatment of cancer. The m6A RNA methylation is the most prevalent internal modification in mammalian mRNAs which plays critical biological roles by regulating vital cellular processes. Mechanistically, FTO exerts its oncogenic role as an m 6 A demethylase by targeting a set of critical transcripts such as ASB2 and RARA. Thus, our study reveals a previously unrecognized mechanism of gene regulation in tumorigenesis and highlights functional importance of FTO and m 6 A modification in cancer.

Previous studies showed that PKM2 promoted tumor growth in xenograft models; however, depletion of PKM2 in the Brca1 -loss–driven mammary tumor mouse model accelerates tumor formation. Because oncogenic kinases are frequently activated in tumors and PKM2 phosphorylation promotes tumor growth, we RNA editing introduces nucleotide changes in RNA sequences.

Li et al. show that FTO, an N6-methyladenosine (m6A) demethylase, is highly expressed in subtypes of AML, promotes leukemogenesis, and inhibits all-trans-retinoic acid-induced leukemia cell differentiation. FTO exerts its oncogenic role by regulating mRNA targets such as ASB2 and RARA by reducing their m6A levels. N6-Methyladenosine was originally identified and partially characterised in the 1970s, and is an abundant modification in mRNA and DNA. It is found within some viruses, and most eukaryotes including mammals, insects, plants and yeast. It is also found in tRNA, rRNA, and small nuclear RNA as well as several long non-coding RNA, such as Xist. The methylation of adenosine is directed by a large m6A methyltransferase complex containing METTL3 as the SAM-binding sub-unit. In vitro, this methyltransfe N6-methyladenosine (m6A) is methylation that occurs in the N6-position of adenosine, which is the most prevalent internal modification on eukaryotic mRNA.
