Endogenous glutamate determines ferroptosis sensitivity via ADCY10-dependent YAP suppression in lung adenocarcinoma.

Rationale: Ferroptosis, a newly identified form of regulated cell death, can be induced following the inhibition of cystine-glutamate antiporter system XC- because of the impaired uptake of cystine. However, the outcome following the accumulation of endogenous glutamate in lung adenocarcinoma (LUAD) has not yet been determined. Yes-associated protein (YAP) is sustained by the hexosamine biosynthesis pathway (HBP)-dependent O-linked beta-N-acetylglucosaminylation (O-G ...[more]

Role of Anlotinib-induced CCL2 decrease in anti-angiogensis and response prediction for Non-Small Cell Lung Cancer therapy

Project description:Purpose: Our previous clinical trials have been demonstrated that Anlotinib can inhibit tumor growth upon refractory advanced non-small cell lung cancer (NSCLC) patients with the possibility mechanism of anti-angiogenesis. The present study sought to reveal the underlying molecular mechanism of Anlotinib-induced anti-angiogenesis in advanced NSCLC. Experimental Design: Computed tomography (CT) was used to evaluate the treatment effect of Anlotinib upon refractory advanced NSCLC patients. Transcriptome profiling was performed to identify the key gene expression alteration in NCI-H1975 cells before and after Anlotinib treatment. NCI-H1975 derived xenograft model was applied to investigate treatment effect and verify anti-angiogenesis mechanism of Anlotinib. Results: Anlotinib induces tumor cytotoxicity on refractory advanced NSCLC patients, NCI-H1975 derived xenograft models and lung adenocarcinoma cell lines. Transcriptome profiling revealed CCL2 blockade could be responsible for Anlotinib-induced anti-angiogenesis. NCI-H1975 derived xenograft model demonstrated Anlotinib-induced CCL2 blockade play an important role in anti-angiogenesis. Conclusions: This study not only offered the first evidence that Anlotinib inhibits angiogenesis via blocking CCL2 expression, but also provided a novel theoretical basis for the application of Anlotinib in advanced NSCLC patients.

Gene expression profile of cell lines 2106T, H1975 and MeWo after knockdown of PAEP.

Project description:Gene expression profile was analyzed after knockdown of PAEP in lung cancer cell lines 2106T and H1975 as well as in skin cancer cell line MeWo. The aim of the study was to investigate the role of PAEP and its protein product glycodelin in lung cancer cell lines. Cells were treated with a control siRNA or a siRNA pool of 4 siRNAs targeting PAEP. RNA of three biological replicates each was extracted and used for Affymetrix analyses.

Quantitative proteomic analysis of gallbladder cancer

Project description:We carried out an iTRAQ-based quantitative proteomic analysis of gallbladder cancer and adjacent non-tumor tissue to systematically identify differentially expressed proteins in gallbladder cancer. Ten gallbladder adenocarcinoma and ten adjacent non-tumor tissue samples were selected post pathological confirmation for the study. Samples were pooled and In-solution trypsin digestion was carried out. Post digestion, peptides were iTRAQ labeled with 114 and 115 (gallbladder adenocarcinoma) and 116 and 117 (adjacent non-tumor samples). LC-MS/MS analysis of SCX fractions was carried out using a reversed phase analytical C18 column connected to 1200 Series Nanoflow LC interfaced with LTQ-Orbitrap Velos. Data were acquired using Xcalibur 2.1. Proteome Discoverer (v 1.3) suite was used for quantitation and database searches. LC-MS/MS data were searched using Mascot and SEQUEST search algorithms against Human RefSeq 50 supplemented with frequently observed contaminants.

ACLY and ACC1 Regulate Hypoxia-Induced Apoptosis by Modulating ETV4 via Î±-ketoglutarate

Project description:In order to propagate a solid tumor, cancer cells must adapt to and survive under various tumor microenvironment (TME) stresses, such as hypoxia or lactic acidosis. To systematically identify genes that modulate cancer cell survival under stresses, we performed genome-wide shRNA screens under hypoxia or lactic acidosis. We discovered that genetic depletion of acetyl-CoA carboxylase (ACACA or ACC1) or ATP citrate lyase (ACLY) protected cancer cells from hypoxia-induced apoptosis. Additionally, loss of ACLY or ACC1 reduced levels and activities of the oncogenic transcription factor ETV4. Silencing ETV4 also protected cells from hypoxia-induced apoptosis and led to remarkably similar transcriptional responses as with silenced ACLY or ACC1, including an anti-apoptotic program. Metabolomic analysis found that while Î±-ketoglutarate levels decrease under hypoxia in control cells, Î±-ketoglutarate is paradoxically increased by hypoxia when ACC1 or ACLY are depleted. Supplementation with Î±-ketoglutarate rescued the hypoxia-induced apoptosis and recapitulated the decreased expression and activity of ETV4 via an epigenetic mechanism. Therefore, ACC1 and ACLY regulate the levels of ETV4 under hypoxia via increased Î±-ketoglutarate. These results reveal that ACC1/ACLY- Î±-ketoglutarate-ETV4 is a novel means by which metabolic states regulate transcriptional output for life vs. death decisions under hypoxia. Since many lipogenic inhibitors are under investigation as cancer therapeutics, our findings suggest that the use of these inhibitors will need to be carefully considered with respect to oncogenic drivers, tumor hypoxia, progression and dormancy. More broadly, our screen provides a framework for studying additional tumor cell stress-adaption mechanisms in the future. DESIGN: H1975 lung cancer cells transduced with a scramble shRNA hairpin or two different shRNAs against ACLY, ACC1, or ETV4 under hypoxia.
