Lung cancer is the leading cause of cancer-related death worldwide. Bromodomain and extraterminal domain (BET) proteins act as epigenome readers for gene transcriptional regulation. Among BET family members, BRD4 was well studied, but for its mechanism in non-small cell lung carcinoma has not been elucidated. eIF4E regulates gene translation and has been proved to play an important role in the progression of lung cancer. In this study, we first confirmed that BET inhibitors JQ1 and I-BET151 suppressed the growth of NSCLCs, in parallel with downregulated eIF4E expression...

Background: Mediastinum harbors a mixed bag of neoplastic lesions with varied therapeutic and prognostic implications. Distinguishing pulmonary squamous cell carcinoma from thymic carcinoma is a challenging task owing to rather nonspecific clinicoradiological features and a considerable overlap in histomorphological features. Thus, we evaluated the diagnostic utility of cluster of differentiation 5 (CD5) and CD117 immunohistochemical markers in distinguishing these tumors. Materials and Methods: The archives of department of histopathology were retrospectively reviewed from June 2012 to May 2016...

Nogo-B receptor (NgBR) is a specific receptor of Nogo-B that regulates vascular remodeling and angiogenesis. Previously, we found that NgBR promotes the membrane translocation and activation of Ras in breast cancer cells and enhances the chemoresistance of hepatocellular carcinoma cells to 5-fluorouracil. However, the role of NgBR in lung cancer has not yet been elucidated. In the present study, we found that NgBR knockdown inhibited epithelial-mesenchymal transition (EMT) in non-small cell lung cancer (NSCLC) cells in vitro and metastasis of NSCLC cells in vivo...

PURPOSE OF REVIEW: Contemporary advances in the understanding of the molecular and immunologic basis of metastatic lung cancer have firmly changed its treatment paradigm to a personalized, biomarker-driven approach. However, the majority of lung-cancer patients [especially lung squamous cell carcinoma (LUSC)] still do not have effective targeted therapeutic options. Master protocols, such as Lung-MAP, represent an innovative clinical trial approach designed to accelerate evaluation of novel biomarker-driven therapies...

D‑allose is a rare sugar which has been shown to have growth inhibitory effects in several kinds of malignancies. However, the effect of D‑allose on lung cancer progression has not been previously studied. To investigate the antitumour effect of D‑allose in lung cancer cells and its mechanism, human non-small cell lung cancer (NSCLC) cell lines (squamous cell carcinomas: EBC1 and VMRC‑LCD; adenocarcinomas: A549, HI1017, RERF‑LC‑A1 and NCI-H1975) were treated with D‑allose (50 mM) with or without cisplatin (5 µM)...

Large cell neuroendocrine carcinoma (LCNEC) of the lung is a highly aggressive tumor without established standard treatment. The Hedgehog (Hh) signal, which is critical in embryogenesis, is known to play important roles in maintaining a malignant phenotype in various cancers. The present study explored the possibility of targeting the Hh signal in the treatment of LCNEC by suppressing Hh downstream molecules, Smoothened (Smo) and GLI family zinc finger 1/2 (Gli1/2), in 3 human LCNEC cell lines. Smo inhibitor, BMS-833923, and Gli inhibitor, GANT61, downregulated Gli1 and 2, resulting in the suppression of the cell viability of the 3 cell lines as assessed using an MTT assay...

In the light of novel cancer immune therapies, the status of antitumor inflammatory response and its regulation has gained much attention in patients with lung cancer. Ample datasets exist for non-small cell lung cancer, but those for pulmonary neuroendocrine tumors are scarce and controversial. Here, tumor-associated inflammation, CD8+ cell infiltration and PD-L1 status were evaluated in a cohort of 57 resected carcinoids and 185 resected neuroendocrine carcinomas of the lung (58 large cell carcinomas and 127 small cell carcinomas)...

Alectinib, a highly selective next-genetation anaplastic lymphoma kinase (ALK) inhibitor, has demonstrated promising antitumor activity in patients with ALK-positive non-small cell lung carcinomas (NSCLC). However, the therapeutic benefits of alectinib is inescapably hampered by the development of acquired resistant mutations in ALK. Despite the availability of ample experimental mutagenesis data, the molecular origin and the structural motifs under alectinib binding affinity deficiencies are still ambiguous...

AIMS: With immunomodulatory therapy being integrated into treatment regimes for non-small cell carcinoma (NSCLC), we prospectively collected data on the immunohistochemical profile of tumours assessed in our institution and correlated this with morphological tumour features. METHODS AND RESULTS: Immunohistochemistry for PD-L1 was considered adequate when more than 100 tumour cells were seen microscopically. When adequate, PD-L1 staining was scored as <1%, ≥ 1-49% or ≥ 50% positive membrane staining within tumour cells only...

BACKGROUND: Malignant tumors are typically caused by a conglomeration of genomic aberrations-including point mutations, small insertions, small deletions, and large copy-number variations. In some cases, specific chemotherapies and targeted drug treatments are effective against tumors that harbor certain genomic aberrations. However, predictive aberrations (biomarkers) have not been identified for many tumor types and treatments. One way to address this problem is to examine the downstream, transcriptional effects of genomic aberrations and to identify characteristic patterns...

Activated platelets promote the proliferation and metastatic potential of cancer cells. Platelet activation is largely mediated through ADP engagement of purinergic P2Y12 receptors on platelets. We examined the potential of the reversible P2Y12 inhibitor ticagrelor, an agent used clinically to prevent cardiovascular and cerebrovascular events, to reduce tumor growth and metastasis. In vitro, MCF-7, MDA-MB-468, and MDA-MB-231 human mammary carcinoma cells exhibited decreased interaction with platelets treated with ticagrelor compared to untreated platelets...
