Single-cell Transcriptome Analysis Revealed that EGFR Mutation Leads to a Suppressive Tumor Immune Microenvironment in Lung Adenocarcinoma

ABSTRACT: We analyzed 40,799 single cells from nine samples and found that in EGFR-mutant LUAD, tumor cells generated an immunosuppressive microenvironment by releasing cytokines to attract suppressive immune cells such as myeloid-derived suppressor cells (MDSCs) directly or indirectly by interacting with macrophages, dendritic cells, or other cell types. By contrast, EGFR wild-type LUAD had a greater ability to recruit immunocompetent T cells such as TRMs and Th1 cells, thus driving a proinflammatory microenvironment.

Study the differential gene expression of different lung cancer EGFR mutants in NIH3T3 cells

Project description:Oncogenic mutations in the EGFR gene account for 15-20% of lung adenocarcinoma (LUAD) cases. However, the mechanism for EGFR driven tumor development and growth is not fully understood. Here, using a mRNA expression profiling-based approach we identified betacellulin (BTC) as one the gene upregulated by oncogenic EGFR in a MAP kinase-dependent manner. BTC protein expression was markedly increased in LUAD patient samples compared to normal lung tissue, with higher expression in EGFR-mutant LUAD. BTC was sufficient to transform immortalized mouse cells, initiate tumor development in mice, and promote the survival of immortalized human lung epithelial cells. Conversely, knockdown of BTC inhibited the growth of EGFR-mutant human LUAD cells in culture and their tumor-forming ability in mice. Mechanistically, BTC knockdown resulted in attenuated EGFR signaling and apoptosis induction. Collectively, these results demonstrate a key role of BTC in EGFR-mutant LUAD, with potential therapeutic implications in LUAD and other EGFR-mutant cancers.

Transcription factor ZNF263 enhances EGFR-targeted therapeutic response and reduces residual disease in lung adenocarcinoma [ChIP-seq]

Project description:EGF receptor (EGFR) tyrosine kinase inhibitors (TKIs) have achieved clinical successes in lung adenocarcinoma (LUAD). However, tumors often show profound but transient initial response and gain resistance. Here, we identified transcription factor ZNF263 as being significantly decreased in osimertinib-resistant or drug-tolerant persister LUAD cells and clinical residual tumor specimens. Exogenous expression of ZNF263 improved the initial response of cells and delayed the formation of persister cells with osimertinib. We elaborated that ZNF263 bound and recruited DNMT1 to the EGFR gene promoter, suppressing EGFR transcription with DNA hypermethylation. ZNF263 could also interact with nuclear EGFR (nEGFR), impairing the nEGFR-STAT5 interaction to enhance AURKA expression. Overexpressing ZNF263 also made tumor cells with wild-type EGFR expression or refractory EGFR mutations more susceptible to EGFR inhibition. More importantly, lentivirus or AAV-mediated plasmid delivery of ZNF263 synergistically suppressed tumor growth and regrowth with osimertinib in xenograft animal models. These findings suggest that enhancing ZNF263 may achieve complete response in LUAD with EGFR-targeted therapies.

Asah2 represses the p53-Hmox1 axis to protect myeloid-derived suppressive cells from ferroptosis

Project description:Myeloid-derived suppressor cells (MDSCs) are immune suppressive cells that massively accumulate under pathological conditions to suppress T cell immune response. Dysregulated cell death contributes to MDSC accumulation, but the molecular mechanism underlying this cell death dysregulation is not fully understood. We report here that neutral ceramidase (N-acylsphingosine amidohydrolase, ASAH2) is highly expressed in tumor-infiltrating MDSCs in colon carcinoma and acts as a MDSC survival factor. To target ASAH2, we performed molecular docking based on human ASAH2 protein structure. Enzymatic inhibition analysis of identified hits determined NC06 as an ASAH2 inhibitor. Chemical and NMR analysis determined NC06 as 7-chloro-2-(3-chloroanilino)pyrano[3,4-e][1,3]oxazine-4,5-dione. NC06 inhibits ceramidase activity with IC50 of 10.16-25.91 M for human ASAH2 and 18.6-30.2 uM for mouse Asah2 proteins. NC06 induces MDSC death in a dose-dependent manner and inhibition of ferroptosis decreased NC06-induced MDSC death. NC06 increases glutathione synthesis and decrease lipid ROS to suppress ferroptosis in MDSCs. Gene expression profiling identified p53 pathway as the Asah2 target in MDSCs. Inhibition of Asah2 increased p53 protein stability to up-regulate Hmox1 expression to suppress lipid ROS production to suppress ferroptosis in MDSCs. NC06 therapy increases MDSC death and reduces MDSC accumulation in tumor-bearing mice, resulting in increased activation of tumor-infiltrating CTLs and suppression of tumor growth in vivo. Our data indicate that ASAH2 protects MDSCs from ferroptosis through destabilizing p53 protein to suppress the p53 pathway in MDSCs in the tumor microenvironment. Targeting ASAH2 with NC06 to induce MDSC ferroptosis is potentially an effective therapy to suppress MDSC accumulation in cancer immunotherapy.

LncRNA RP3-340N1.2 affects the progression of lung adenocarcinoma cell lines by targeting miR-134-5p

Project description:We found lncRNA RP3-340N1.2 is highly expressed in LUAD and relatived with the progression of LUAD through high-throughput sequencing. Our results showed that the expression level of RP3-340N1.2 was upregulated significantly in three LUAD cell lines (A549, NCI_x001E_H1299, and NCI-H1975) and lentivirus-mediated knockdown of RP3-340N1.2 inhibited the differentiation, proliferation, migration, invasion, cell cycle, and other biological processes of tumor cells significantly. Bioinformatic software predicted the downstream target of RP3-340N1.2, which was verified using dual luciferase assays and other methods. We found that RP3-340N1.2 can competitively bind miR-134-5p in LUAD, and this microRNA has a significant regulatory effect on the expression of epidermal growth factor receptor (EGFR), which leads to increased migration and invasion of LUAD cells. This discovery provided a possible mechanism by which RP3-340N1.2 participates in the development of LUAD. In conclusion, our results showed that lncRNA RP3_x001E_340N1.2 regulates the expression of EGFR indirectly by targeting miR-134-5p and promotes the progression of LUAD. Therefore, RP3-340N1.2 may become a valuable biomarker and therapeutic target in LUAD.

Gene expression data from the tumor cell supernatant-induced MDSCs

Project description:Myeloid derived suppressor cells (MDSCs) markedly expand and participate in the suppression of immune responses in inflammation and tumor microenvironment. It was confirmed that MDSCs could be generated in vitro from bone marrow cells (BMCs) after 4 days GM-CSF only or GM-CSF plus IL-6 treatment. To identify the regulation of MDSCs in tumor microenvironment, we analyzed the gene expression from tumor cell ID8 supernant-induced MDSCs compared to BMCs.

Transcriptomic hallmarks of tumor plasticity and stromal interactions in brain metastasis [BrainMet_SQ_2D]

Project description:We find that malignant LUAD tumor cells grown in the brain microenvironment display significantly altered transcriptomic profiles when compared to tumor cells grown in monolayer or subcutaneously. Additionally, we characterize the reciprocal neuroinflammatory response of the surrounding brain stroma to metastatic LUAD. This dataset can be utilized to explore the mechanisms of LUAD cell plasticity as well as the co-adaptation of the brain microenvironment to metastatic disease.

Effect of depletion of KDM4D, NFIB, and MLL1 on gene expression during adipogenic differentiation of C3H10T1/2 mesenchymal stem cells

Project description:The limited efficacy of currently approved immunotherapies in EGFR-mutant lung adenocarcinoma (LUAD) underscores the need to better understand alternative mechanisms governing local immunosuppression to fuel novel therapies. Elevated surfactant and GM-CSF secretion from the transformed epithelium induces tumor-associated alveolar macrophages (TA-AM) to proliferate and support tumor growth by rewiring inflammatory functions and lipid metabolism. TA-AM properties are driven by increased GM-CSF—PPARγ signaling and inhibition of airway GM-CSF or PPARγ in TA-AMs suppresses cholesterol efflux to tumor cells, which impairs EGFR phosphorylation and restrains LUAD progression. In the absence of TA-AM metabolic support, LUAD cells compensate by increasing cholesterol synthesis, and blocking PPARγ in TA-AMs simultaneous with statin therapy further suppresses tumor progression and increases T cell effector functions. These results reveal new therapeutic combinations for immunotherapy resistant EGFR-mutant LUADs and demonstrate how such cancer cells can metabolically co-opt TA-AMs through GM-CSF—PPARγ signaling to provide nutrients that promote oncogenic signaling and growth.
