Id1 promotes carcinogenesis and metastasis, and predicts prognosis of non-small cell lung cancer (NSCLC)-adenocarcionoma patients. We hypothesized that Id1 may play a critical role in lung cancer colonization of the liver by affecting both tumor cells and the microenvironment. Depleted levels of Id1 in LLC (Lewis lung carcinoma cells, LLC shId1) significantly reduced cell proliferation and migration in vitro. Genetic loss of Id1 in the host tissue (Id1(-/-) mice) impaired liver colonization and increased survival of Id1(-/-) animals...

Adenocarcinoma (ADC) and squamous cell carcinoma (SqCC) are the two predominant subtypes of non-small cell lung cancer (NSCLC) and are distinct in their histological, molecular and clinical presentation. However, metabolic signatures specific to individual NSCLC subtypes remain unknown. Here, we perform an integrative analysis of human NSCLC tumour samples, patient-derived xenografts, murine model of NSCLC, NSCLC cell lines and The Cancer Genome Atlas (TCGA) and reveal a markedly elevated expression of the GLUT1 glucose transporter in lung SqCC, which augments glucose uptake and glycolytic flux...

REVIEW
Vera Hirsh
Until recently, few treatment options existed for the treatment of squamous cell carcinoma (SqCC) of the lung, especially in the second-line setting following platinum-based chemotherapy. Accordingly, outcomes in this subtype of non-small-cell lung cancer (NSCLC) were generally poor. In this context, the recent availability of the checkpoint inhibitors nivolumab and pembrolizumab, the anti-VEGFR2 antibody ramucirumab (combined with docetaxel), and the ErbB-family blocker afatinib for the treatment of relapsed/refractory SqCC of the lung represent major advances...

Recognition of major histocompatibility complex (MHC) class I antigens on tumor cells by cytotoxic T cells is involved in T cell-mediated tumor immune surveillance and immune checkpoint therapy. The interferon-γ (IFNγ)-IRF1 signaling pathway regulates MHC class I antigen presentation. To examine genetic defects of the IFNγ-IRF1 pathway in non-small cell lung cancer (NSCLC), we analyzed The Cancer Genome Atlas (TCGA) lung adenocarcinoma (LuAd) and lung squamous cell carcinoma (LuSc) data. Loss-of-function (LOF) genetic alterations of the IFNγ-IRF1 pathway genes (IFNGR1, IFNGR2, JAK1, JAK2, STAT1, IRF1) were found in 64 (6...

Several homeobox-related gene (HOX) transcription factors such as mesenchyme HOX-2 (MEOX2) have previously been associated with cancer drug resistance, malignant progression and/or clinical prognostic responses in lung cancer patients; however, the mechanisms involved in these responses have yet to be elucidated. Here, an epigenomic strategy was implemented to identify novel MEOX2 gene promoter transcription targets and propose a new molecular mechanism underlying lung cancer drug resistance and poor clinical prognosis...

BACKGROUND: The programmed cell death-1 (PD-1) pathway is a novel therapeutic target in immune checkpoint therapy for cancer. It consists of the PD-1 receptor and its two ligands, programmed death-ligand 1 (PD-L1) and programmed death-ligand 2 (PD-L2). Nivolumab is an anti-PD-1 monoclonal antibody approved for malignant melanoma, advanced non-small cell lung cancer, and advanced renal cell carcinoma in Japan. Thyrotoxicosis and hypothyroidism have both been reported in international phase 3 studies and national postmarketing surveillance of nivolumab in Japan...

INTRODUCTION: Large cell carcinoma with or without neuroendocrine features (LCNEC and LC, respectively) constitutes a small proportion of non-small cell lung cancer (NSCLC). The WHO2015 classification guidelines changed the definition of the debated histological subtype LC to be based on immunomarkers for adenocarcinoma and squamous cancer. We sought to determine if these new guidelines translate also to the transcriptional landscape of lung cancer, and LC specifically. METHODS: Gene expression profiling was performed using Illumina V4 HT12 microarrays on 159 cases (comprising all histological subtypes including 10 WHO2015 LC and 14 LCNEC tumors), with complimentary mutational and IHC data...

MicroRNAs (miRNAs) are a large family of small, non-coding RNAs that play a pivotal role in tumorigenesis. miR‑34a, which is a member of the miR-34 family, is a downstream target of p53. Increasing evidence shows that miR-34a dysregulation may contribute to tumor development and progression in numerous cancers, including esophageal squamous cell carcinoma (ESCC). However, the mechanism of miR-34a in the regulation of ESCC cells need to be further elucidated because of the complex regulative network of miRNAs...

PURPOSE: Gliomas are the most common primary intracranial tumors of the central nervous system (CNS), accounting for about one third of all brain tumors. Glioblastoma multiforme (GBM) is the aggressive grade IV glioma with survival as low as 2-5% in the second year post-diagnosis, hence necessitating efficient diagnostic markers. More than 50% of the non-small cell lung cancer (NSCLC) brain metastases are solitary lesions, often difficult to differentiate from gliomas by conventional imaging diagnostics...

The incidence of hepatocellular carcinoma (HCC) is increasing in the United States and liver cancer is the second leading cause of cancer-related mortality worldwide. Non-alcoholic steatohepatitis (NASH) is becoming an important risk for HCC and most patients with HCC have underlying liver cirrhosis and compromised liver function, which limit treatment options. Thus, novel therapeutic strategies to prevent or treat HCC in the context of NASH and cirrhosis are urgently needed. <br /><br />Experimental Design: Constitutive activation of signal transducer and activator of transcription 3 (STAT3) is frequently detected in HCC tumors...
