17, 18 Imatinib, a potent KIT inhibitor, is currently used as first‐line therapy of GIST The basic elements required for oncogenic transformation remain undefined. By analyzing glucose-6-phosphate dehydrogenase (G6PD)-mediated oncogenic transformation, Zhang et al. show that upregulation of antioxidant defense and nucleotide production suffices to transform murine and human cells. Therefore, oncogenic transformation may involve overcoming a limited redox balance capacity and Receptor tyrosine kinases (RTKs) activate pathways mediated by serine-threonine kinases, such as the PI3K (phosphatidylinositol 3-kinase)–Akt pathway, the Ras–MAPK (mitogen-activated protein kinase)–RSK (ribosomal S6 kinase) pathway, and the mTOR (mammalian target of rapamycin)–p70 S6 pathway, that control important aspects of cell growth, proliferation, and survival. 2018-02-19 · Deregulated activity of BCR-ABL1, a nonreceptor tyrosine kinase encoded by the fusion gene resulting from the t(9;22)(q34;q11) chromosomal translocation, is thought to be the driver event responsible for initiation and maintenance of chronic myeloid leukemia (CML).

However, the clinical significance and the functional role of RNA editing in colorectal cancer (CRC) remain unclear. Targeting energy metabolic and oncogenic signaling pathways in triple-negative breast cancer by a novel adenosine monophosphate-activated protein kinase (AMPK) activator. Journal of Biological Chemistry , 286 (45), 39247-39258. 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 Background: Adenosine monophosphate-activated protein kinase (AMPK) modulates cancer cell metabolism and survival.

The role of pyruvate kinase M2 isoform (PKM2) in tumor progression has been controversial. 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

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. 2011-06-09 · Using limited proteolysis assays, nucleotide-binding assays, and single-turnover and steady-state GTPase assays, we demonstrate that the oncogenic R234H mutation renders Gαo constitutively active by accelerating the rate of nucleotide exchange; however, this mutation does not affect Gαo's ability to become deactivated by GTPase-activating proteins (GAPs) or by its intrinsic GTPase activity.

Recent studies have reported that aberrant A-to-I RNA editing profiles are implicated in cancers. Albeit changes in expression and activity of ADAR genes are thought to have been responsible for the dysregulated RNA editome in diseases, they are not always correlated, indicating the involvement of secondary regulators. Regorafenib also demonstrated potent inhibition (20–40 nM) of the oncogenic RTKs KIT K642E and RET C634W in vitro (Table 1), which indicates that regorafenib may have clinical potential in tumor types driven by mutated RET, which occurs in a subset of medullary thyroid tumors, or mutated KIT in GIST. 17, 18 Imatinib, a potent KIT inhibitor, is currently used as first‐line therapy of GIST The basic elements required for oncogenic transformation remain undefined. By analyzing glucose-6-phosphate dehydrogenase (G6PD)-mediated oncogenic transformation, Zhang et al.

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.

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.

We profiled m6A in PCa cell lines and have identified important N6-adenosine methylated RNAs associated with  Adenosine is involved in a range of physiological and pathological effects through membrane-bound receptors linked to G proteins.
