2021-01-28 · Background N6-methyladenosine (m6A) and adenosine-to-inosine (A-to-I) RNA editing are two of the most abundant RNA modification events affecting adenosines in mammals. Both these RNA modifications determine mRNA fate and play a pivotal role in tumor development and progression. Results Here, we show that METTL3, upregulated in glioblastoma, methylates ADAR1 mRNA and increases its protein level
Celular Signalling 2003. The purine nucleoside adenosine acts via four distinct adenosine receptor subtypes: the adenosine A(1), A(2A)
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. Of note, neither adenosine nor adenine was able to alter MIR22HG levels in control cells, raising the hypothesis of a threshold, rather than a dose-dependent, mechanism for adenosine (and adenine Request PDF | Abstract 1365: Sensitivity of oncogenic KRAS to adenosine triphosphate suppression | KRAS proteins regulate many cellular processes including initiation of cell division in response immunosuppressive effects of adenosine in experimental tumor models. • Oncogene-driven cancers tend to be non-responsive to PD(L)-1 inhibition. Herein we show that oncogenic alterations can modulate expression of genes of the adenosine pathway. Interested in a career at Arcus?

Aurora-2 is oncogenic and amplified in various human cancers and could be an important therapeutic target for inhibitory molecules that would disrupt the cell cycle and block proliferation. We report the first crystal structure of Aurora-2 kinase in complex with adenosine. 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.

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.

doi: 10.1074/jbc.M111.264598. An oncogenic variant, RL34HT, appeared to be more functionally active than its nononcogenic counterparts with respect to cell surface adenosine 5'-triphosphatase (ecto-ATPase) as well as to cytoplasmic enzymes such as tyrosine aminotransferase, gamma-glutamyl transpeptidase, and alkaline phosphatase. 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.
