Breviscapine (BVP) has previously been shown to inhibit the proliferation of hepatocellular carcinoma cells. However, little is known about the effects of BVP on non-small cell lung cancer (NSCLC) growth. Here, we aimed to study the effects of BVP on human NSCLC growth. We employed A549, NCL-H460 and A549 cells transfected with microRNA-7 (miR-7) mimic and inhibitor to investigate the effect of BVP on cell proliferation, apoptosis and apoptosis-associated molecules. The results showed that BVP significantly reduced the growth of A549 and NCLH460 cells in a concentration-dependent and time-dependent manner, accompanied by a significant elevation of apoptosis...

A 65-year-old man visited our hospital with dyspnea and cough. He was diagnosed with small cell lung carcinoma (cT4N2M1b, Stage IV). The disease partially responded to systemic chemotherapy. However, it was progressive and metastasized to the brain 3 months after 6 courses of chemotherapy. Therefore, whole brain irradiation was performed. Subsequently, weakness of the lower extremities and vesicorectal disturbances appeared. Meningeal carcinomatosis was diagnosed by enhanced magnetic resonance imaging and liquid examination...

PURPOSE: With recent approval of inhibitors of PD-1 in melanoma, non-small cell lung cancer (NSCLC) and renal cell carcinoma (RCC), extensive efforts are underway to develop biomarkers predictive of response. PD-L1 expression has been most widely studied, and is more predictive in NSCLC than RCC or melanoma. We therefore studied differences in expression patterns across tumor types. EXPERIMENTAL DESIGN: We employed tissue microarrays with tumors from NSCLC, RCC or melanoma and a panel of cell lines to study differences between tumor types...

Interleukin-32 (IL-32) is a novel cytokine involved in inflammation and cancer development. IL-32 gene consists of eight small exons, and IL-32 mRNA has nine alternative spliced isoforms, and was thought to be secreted because it contains an internal signal sequence and lacks a transmembrane region. IL-32 is initially expressed selectively in activated T cells by mitogen and activated NK cells and their expression is strongly augmented by microbes, mitogens, and other cytokines. The IL-32 is induced mainly by pathogens and pro-inflammatory cytokines, but IL-32 is more prominent in immune cells than in non-immune tissues...

Alternative splicing provides a major mechanism to generate protein diversity. Increasing evidence suggests a link of dysregulation of splicing associated with cancer. Genome-wide alternative splicing profiling in lung cancer remains largely unstudied. We generated alternative splicing profiles in 491 lung adenocarcinoma (LUAD) and 471 lung squamous cell carcinoma (LUSC) patients in TCGA using RNA-seq data, prognostic models and splicing networks were built by integrated bioinformatics analysis. A total of 3,691 and 2,403 alternative splicing events were significantly associated with patient survival in LUAD and LUSC, respectively, including EGFR, CD44, PIK3C3, RRAS2, MAPKAP1 and FGFR2...

BACKGROUND: Immunotherapy can become a crucial therapeutic option to improve the prognosis of patients with non-small-cell lung cancer (NSCLC). Here, we evaluated the impact of programmed cell death ligand-1 (PD-L1) expression in surgically resected NSCLCs. METHODS: We estimated PD-L1 expression in 229 consecutive NSCLC specimens using rabbit polyclonal antibodies to human PD-L1 in a SP263 immunohistochemical assay and evaluated PD-L1 expression for potential associations with clinicopathological parameters and survival time...

The authors present a case of Merkel cell carcinoma (MCC) with unique immunohistochemical staining characteristics. A 57-year-old woman presented with a firm 0.3 cm tan papule on her left nasal-labial fold that was reportedly increasing in size and bleeding. She had a history of multiple head and neck actinic keratoses, papillary thyroid carcinoma, and a family history of an uncle with melanoma. The clinical differential diagnosis was "non-melanoma skin cancer." Histological examination showed a markedly atypical-appearing basaloid neoplasm, present mostly in the dermis, with focal pagetoid spread into the epidermis...

AKR1B10 is a human-type aldo-keto reductase. The up-regulation of AKR1B10 has been associated with various cancers including non-small cell lung carcinoma, viral and bacterial infections, and skin diseases. However, the mechanisms underlying AKR1B10 gene regulation are not fully understood. We previously indicated the involvement of the transcription factor Nrf2 in AKR1B10 gene regulation. There are at least five potential Nrf2-responsive consensus sequences, so-called antioxidant response elements (AREs), and several ARE-like sequences in the 5'-flanking region up to -3282 bp of the AKR1B10 gene...

The carcinogenesis of non-small cell lung carcinoma has been found to associate with activating and resistant mutations in the tyrosine kinase domain of specific oncogenes. Here, we assessed the type, frequency, and abundance of epithelial growth factor receptor, KRAS, BRAF, and ALK mutations in 154 non-small cell lung carcinoma specimens using single-molecule amplification and re-sequencing technology. We found that epithelial growth factor receptor mutations were the most prevalent (44.2%), followed by KRAS (18...

Ocular medulloepithelioma (ME) is a rare congenital tumor which occurs usually during childhood but is also reported in adults. They have seen an intraocular tumor in an 89 years-old female with a history of small cell lung carcinoma. Transscleral fine needle aspiration was performed. Aspirates were rich and composed of two distinctive populations of cells. The first consisted of epithelioid large cohesive cells with rare rosettes. Nuclei were oval and chromatin was delicate with small nucleoli. The second population consisted of smaller and dispersed cells with regular nuclei and dusty chromatin...

OBJECTIVES: Programmed cell death-ligand 1 (PD-L1) expressed in tumor tissues is a key molecule for immune suppression, given its role in immune checkpoints. The significance and implication of soluble PD-L1 (sPD-L1) in the blood of lung cancer patients remain unknown. PATIENTS AND METHODS: Blood samples were prospectively collected from patients with advanced lung cancer, and the plasma sPD-L1 concentrations were measured by enzyme-linked immunosorbent assay. The correlations of the plasma sPD-L1 levels with clinico-pathological status, laboratory data, and survival of the patients were analyzed...

Malignant melanoma is the deadliest form of all skin cancers. Itraconazole, a commonly used systemic antifungal drug, has been tested for its anti-tumor effects on basal cell carcinoma, prostate cancer, and non-small cell lung cancer. Whether itraconazole has any specific anti-tumor effect on melanoma remains unknown. However, the goal of this study is to investigate the effect of itraconazole on melanoma and to reveal some details of its underlying mechanism. In the in vivo xenograft mouse model, we find that itraconazole can inhibit melanoma growth and extend the survival of melanoma xenograft mice, compared to non-itraconazole-treated mice...

Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) selectively triggers cancer cell death via its association with death receptors on the cell membrane, but exerts negligible side effects on normal cells. However, some non-small-cell lung carcinoma (NSCLC) patients exhibited resistance to TRAIL treatment in clinical trials, and the mechanism varies. In this study, we described for the first time that toosendanin (TSN), a triterpenoid derivative used in Chinese medicine for pain management, could significantly sensitize human primary NSCLC cells or NSCLC cell lines to TRAIL-mediated apoptosis both in vitro and in vivo, while showing low toxicity against human primary cells or tissues...

BACKGROUND: Pulmonary large cell neuroendocrine carcinoma (LCNEC) is pathologically classified as non-small-cell lung cancer (NSCLC), but its clinical behavior is more aggressive than other types of NSCLC. Accordingly, the optimal treatment strategy for LCNEC, including the indication of adjuvant treatment, remains controversial. METHODS: A retrospective review of 139 patients who underwent curative-intent surgery for LCNEC was performed to investigate clinicopathologic features and survival outcomes and to evaluate whether adjuvant treatment affected survival outcomes...

While parenchymal metastases are common in solid systemic cancers, subependymal metastases are rare. Approximately half of the reported cases of intraventricular metastases originate from renal carcinoma. A 65-year-old man presented with general fatigue, appetite loss, nausea, and disorientation. Radiological examination revealed diffuse periventricular tumors. The patient underwent an open biopsy via right frontotemporal craniotomy. The patient was diagnosed with metastatic small cell lung carcinoma after histopathological examination...

To improve treatment outcomes in non-small cell lung cancer (NSCLC), preclinical models that can better predict individual patient response to novel therapies are urgently needed. Using freshly resected tumor tissue, we describe an optimized ex vivo explant culture model that enables concurrent evaluation of NSCLC response to therapy while maintaining the tumor microenvironment. We found that ~70% of primary NSCLC specimens were amenable to explant culture with tissue integrity intact for up to 72 hours after explant...
