Abstract
Introduction EGFR mutations in non-small cell lung cancer (NSCLC) are associated with a poor response to immune checkpoint inhibitors (ICIs), and only 20% of NSCLC patients harboring EGFR mutations benefit from immunotherapy. Novel biomarkers or therapeutics are needed to predict NSCLC prognosis and enhance the efficacy of ICIs in NSCLC patients harboring EGFR mutations, especially lung adenocarcinoma (LUAD) patients, who account for approximately 40–50% of all NSCLC cases. Methods An ARID1A-knockdown (ARID1A-KD) EGFR-mutant LUAD cell line was constructed using lentivirus. RNA-seq and mass spectrometry were performed. Western blotting and IHC were used for protein expression evaluation. Effects of 3-MA and rapamycin on cells were explored. Immunofluorescence assays were used for immune cell infiltration examination. Results ARID1A expression was negatively associated with immune cell infiltration and immune scores for ICIs in LUAD with EGFR mutations. In vitro experiments suggested that ARID1A-KD activates the EGFR/PI3K/Akt/mTOR pathway and inhibits autophagy, which attenuates the inhibition of Rig-I-like receptor pathway activity and type I interferon production in EGFR-mutant LUAD cells. In addition, 3-MA upregulated production of type I interferon in EGFR-mutant LUAD cells, with an similar effect to ARID1A-KD. On the other hand, rapamycin attenuated the enhanced production of type I interferon in ARID1A-KD EGFR-mutant LUAD cells. ARID1A function appears to influence the tumor immune microenvironment and response to ICIs. Conclusion ARID1A deficiency reverses response to ICIs in EGFR-mutant LUAD by enhancing autophagy-inhibited type I interferon production. Video Abstract

Abstract
INTRODUCTION The acquired resistance mechanisms in patients with epidermal growth factor receptor (EGFR)-mutant lung cancer, particularly adenocarcinoma (ADC), following treatment with an EGFR tyrosine kinase inhibitor (TKI) have received extensive investigations. The phenotypic transformation to small cell carcinoma (SCCT) has been estimated to occur in approximately 3 to 10% of patients treated with an EGFR-TKI. The prognosis after SCCT is extremely poor. CASE STUDY We report about SCCT that occurred 45 months after the initial diagnosis of ADC in an East Asian never-smoker woman with advanced-stage EGFR Del-19-mutant lung ADC treated with combined chemoradiotherapy before the era of insurance coverage for EGFR-TKIs in this country and subsequently gefitinib; deletion at codon 746-750 in exon 19 of the EGFR gene was ascertained in the original formalin-fixed paraffin-embedded lung biopsy tissue. Spinal cord compression at thoracic-12 level from SCCT was successfully relieved with neurosurgical treatment, chemotherapy with etoposide and cisplatin, and radiotherapy, while gefitinib treatment was maintained. Eleven months later, SCCT relapsed in the lung parenchyma, which was resected and was found to be sensitive to second-line weekly topotecan. Prophylactic cranial irradiation was subsequently administered. SCCT was confirmed by MALDI-TOF MS analysis of formalin-fixed paraffin-embedded tissues demonstrating the same exon 19 deletion. At the 12th-year follow-up, the patient remains relapse free with very good performance status. The novelty of this case is the successful interdisciplinary team effort to correct the spinal cord compression by maintaining the patient in an ambulatory state, non-stop use of gefitinib justified by the presence of activating EGFR mutation in SCCT tumor cells, and aggressive dose-intensive chemotherapy and radiotherapy for the SCCT that leads to an unprecedented prolonged remission and survival. This case also supports the observation that SCCT is chemotherapy sensitive, and thus, re-biopsy or complete tumor excision is recommended to understand the mutation profiles of the current tumor. Aggressive prudent administration of systemic chemotherapy obtaining optimal dose intensity leads to the successful management of the patient.

Abstract
Although most EGFR-mutant lung adenocarcinomas initially respond to EGFR inhibitors, disease progression almost inevitably occurs. We previously reported that two EGFR-mutant lung adenocarcinoma cell lines, HCC827 and H1975, contain subpopulations of cells that display an epithelial-to-mesenchymal phenotype and can thrive independently of EGFR signaling. In this study, we explored to what extent these two sublines, HCC827 GR2 and H1975 WR7, depended on the anti-apoptotic BCL2 family members, Bcl-xL and/or MCL1, for survival. Although HCC827 GR2 cells were hardly affected by Bcl-xL or MCL1 knockdown alone, dual inhibition of Bcl-xL and MCL1 caused the cells to undergo apoptosis, resulting in decreased viability. In H1975 WR7 cells, not only dual inhibition, but also MCL1 silencing alone, induced the cells to undergo apoptosis. Interestingly, the two sublines markedly declined in number when autophagy flux was suppressed, because they depend, in part, on active autophagy for survival. However, autophagy inhibition was inferior to dual inhibition of Bcl-xL plus MCL1 for GR2 cells, or MCL1 inhibition alone, for decreasing the viability of WR7 cells. Collectively, these findings suggest that inhibiting Bcl-xL plus MCL1, or MCL1 alone, may represent a new approach to treat EGFR-independent EGFR-mutant cancer cells.

Abstract
As a newly discovered deubiquitinating enzyme, ubiquitin-specific protease 22 (USP22) is predictive of therapeutic outcomes in individual cancer patients. However, its clinical effects on malignancy and its roles in conferring resistance to EGFR-TKIs (epidermal growth factor receptor-tyrosine kinase inhibitors) in lung adenocarcinoma (ADC) remain largely unknown. Here, we showed that USP22 promotes cell proliferation, migration and invasion, and contributes to resistance to EGFR-TKIs in EGFR mutant lung ADC cells. Mechanistically, USP22 deubiquitinates EGFR localized on late endosomes, prevents ubiquitination mediated EGFR degradation and enhances recycling of EGFR after EGF stimulation. Additionally, USP22 sustained the activation of multiple EGFR downstream signaling pathways, including STAT3, AKT/mTOR and MEK/ERK pathways, in lung ADC cell lines H1975 and PC9. Furthermore, USP22 stabilizes EGFR protein expression, which correlates with USP22 expression in EGFR-mutant lung ADC patient samples. We are the first to demonstrate that silencing USP22 counteracts EGFR-TKIs resistance both in vitro and in vivo. We propose USP22 as a potential therapeutic target for EGFR-TKIs-resistant lung ADC.

Abstract
EGFR-mutant lung adenocarcinomas contain a subpopulation of cells that have undergone epithelial-to-mesenchymal transition and can grow independently of EGFR. To kill these cancer cells, we need a novel therapeutic approach other than EGFR inhibitors. If a molecule is specifically expressed on the cell surface of such EGFR-independent EGFR-mutant cancer cells, it can be a therapeutic target. We found that a mesenchymal EGFR-independent subline derived from HCC827 cells, an EGFR-mutant lung adenocarcinoma cell line, expressed angiotensin-converting enzyme 2 (ACE2) to a greater extent than its parental cells. ACE2 was also expressed at least partially in most of the primary EGFR-mutant lung adenocarcinomas examined, and the ACE2 expression level in the cancer cells was much higher than that in normal lung epithelial cells. In addition, we developed an anti-ACE2 mouse monoclonal antibody (mAb), termed H8R64, that was internalized by ACE2-expressing cells. If an antibody-drug conjugate consisting of a humanized mAb based on H8R64 and a potent anticancer drug were produced, it could be effective for the treatment of EGFR-mutant lung adenocarcinomas. A mesenchymal EGFR-mutant lung adenocarcinoma cell line expresses ACE2. EGFR-mutant lung adenocarcinoma tissues contain cancer cells that express ACE2. We developed an anti-ACE2 antibody that is internalized by ACE2-positive cells. ACE2 is a potential therapeutic target for EGFR-mutant lung cancer.
