In our study, overexpression of AK4 reduced HIF-1α hydroxylation in the presence of MG132, suggesting that AK4 may stabilize HIF-1α protein by decreasing PHD activity via ROS accumulation. Figure 4. doi: 10.1016/j.yexmp.2009.01.003. 2020 Apr 17;48(7):3638-3656. doi: 10.1093/nar/gkaa130. Siegel R., Desantis C. & Jemal A. Colorectal cancer statistics, 2014. Hypoxia-inducible factor-1alpha is a key regulator of metastasis in a transgenic model of cancer initiation and progression. Overexpression of AK4 shifts metabolism toward aerobic glycolysis and increases the levels of intracellular reactive oxygen species (ROS), which subsequently stabilizes HIF-1α protein and promotes epithelial-to-mesenchymal transition (EMT) in lung cancer cells in a HIF-1α-dependent manner.

Hypoxia-inducible factor-1 alpha in non small cell lung cancer: relation to growth factor, protease and apoptosis pathways. Through pharmacogenomics analysis, we identified withaferin-A as a potential inhibitor that reverses the AK4-induced gene signature and acts as a potent anti-metastatic agent in lung cancer.

HIF-1 mediates metabolic responses to intratumoral hypoxia and oncogenic mutations. High Vmax (rapid phosphorylation of glucose). Mimura I, Nangaku M, Kanki Y, Tsutsumi S, Inoue T, Kohro T, et al. 2019 Feb;20:1-13. doi: 10.1016/j.molmet.2018.11.013. ROS levels were quantified using CellROX Deep Red Reagent (Invitrogen). Intriguingly, among the four members of PFKFB family, PFKFB3 is uniquely localized in the nucleus, although the reason remains unclear. The use of general antioxidants might alleviate circulating tumor cells from oxidative stress and accelerate metastasis development. Pyruvate + ATP, (-) Citrate (high flux of carbons from
Metabolic alterations in mammary cancer prevention by withaferin a in a clinically relevant mouse model. Figure S3.
During metabolic stress, AMP-activated protein kinase (AMPK) is activated by sensing a decrease in the ratio of ATP to AMP, leading to inhibition of ATP-consuming metabolic pathways and activation of energy-producing pathways [6]. N Engl J Med. CL1-0 vector- and AK4-expressing cells were subcutaneously injected into NSG mice. California Privacy Statement, However, HIF-1α mRNA was not affected by AK4 overexpression (Fig.

is a co-founder of Vivace Therapeutics. These findings represent a novel vicious cycle between AK4 and HIF-1α in response to hypoxic stress during lung cancer progression and highlight the therapeutic opportunity of targeting the AK4-HIF-1α axis in NSCLC. Non-coding RNAs Functioning in Colorectal Cancer Stem Cells.

However, the impact of AK4 expression and/or hypoxia on global glycosylation profile in lung cancer remains to be further elucidated. Two-tailed, unpaired Student’s t tests were used for all pairwise comparisons.

Orthotopic xenograft mouse models were established to evaluate the therapeutic efficacy of drug candidates for metastatic lung cancer. so that it is active even at low glucose concentrations.

Inhibition of PFKFB3 cooperates with cisplatin to inhibit xenograft growth. Moreover, in animal studies, we showed that overexpression of AK4 not only protects tumors from hypoxic necrosis but also enhances their ability to metastasize.

Springer Nature. Previous studies have shown that AK4 is one of the hypoxia responsive genes and AK4 is also a transcriptional target of HIF-1α [22,23,24,25]. Infected cells were selected using 2 μg/mL puromycin. Figure S2. Protein expression was visualized using a 3,3′-diaminobenzidine (DAB) peroxidase substrate kit (Ventana, USA). Cell Signal. Acetylation of MORC2 by NAT10 regulates cell-cycle checkpoint control and resistance to DNA-damaging chemotherapy and radiotherapy in breast cancer.
To this end, we also found the expression GnT-V protein was regulated by AK4 under hypoxia in a HIF-1α-dependent manner (Additional file 1: Figure S2A). We first calculated the Pearson correlation coefficient between AK4 expression and each coding gene and ranked the genes according to their correlation coefficient to AK4 expression. Rev. 1) Ingenuity upstream analysis of consensus AK4 metabolic gene signature between GSE31210 and TCGA LUAD. 2004;111(1):43–50.

Synthesis induced by insulin. The results are presented as the mean ± SD of at least three separate experiments. Specifically, the modification of E-cadherin protein at Asn-554 with β1,6-N-acetylglucosamin (β1,6GlcNAc)-branched N-glycan catalyzed by N-acetylglucosaminyltransferase V (GnT-V) disrupts its cell adhesion function and therefore enhances tumor invasion [51, 52].

Cells were grown in a 6-well plate overnight, and the medium was refreshed with complete medium. 2009;324(5930):1029–33.
At day 28, the lungs and livers were removed for pathological examination.
In contrast, an antioxidant supplement even increased tumor incidence in a genetically engineered mouse model of lung cancer and melanoma [47, 48]. Ingenuity upstream analyses were used to identify potential transcription factors that regulate the AK4 metabolic gene signature.
