OBJECTIVES: To describe the radiological phenotype of HER2-mutant lung cancers on CT at presentation. METHODS: Eligible patients with lung adenocarcinomas with HER2 mutations were stage-matched with two control groups (EGFR- and KRAS-mutant groups). Evaluated CT features of the primary tumor included size, location, consistency, contour, presence of pleural tags and pleural retractions. Presence of pleural effusions, lung metastases, adenopathy, chest wall invasion, and were also recorded...

Non-small cell lung cancer (NSCLC) is one of leading causes of cancer-related death worldwide. Long noncoding RNAs (lncRNAs) has been identified to modulate the tumorigenesis of NSCLC. However, the precise molecular mechanism of lncRNAs in the course is still unclear. Results showed that LINC00339 was significantly up-regulated in NSCLC tissue and cells, which indicated the poor prognosis of NSCLC patients. Loss-of-function experiments showed that LINC00339 silencing inhibited the proliferation and invasion, accelerated the apoptosis, and suppressed the tumor growth of NSCLC cells in vitro and in vivo...

Honey bee larvae products have been widely used as traditional daily supplements and complementary medicine for health promotion. However, there is little scientific evidence about their bioactivities. This study was designed to examine the anti-tumor and anti-metastasis effects of honey bee larvae powder (HLP) and explore the underlying mechanism. A subcutaneous transplantation model (murine breast cancer cell 4T1-LUC) and lung metastasis model (murine melanoma cell B16-F10) were established to evaluate the anti-tumor and anti-metastasis effects of HLP...

Lung cancer is the leading cause of cancer death worldwide. Cigarette smoking and exposure to chemical carcinogens are among the risk factors of lung tumorigenesis. In this study, we found that cigarette smoke condensate and urethane significantly stimulated the expression of sulfiredoxin (Srx) at the transcript and protein levels in cultured normal lung epithelial cells, and such stimulation was mediated through the activation of nuclear related factor 2 (Nrf2). To study the role of Srx in lung cancer development in vivo, mice with Srx wildtype, heterozygous or knockout genotype were subjected to the same protocol of urethane treatment to induce lung tumors...

Deferoxamine (DFO) was found to modulate multiple cellular pathways involved in the growth of breast cancer, hepatocellular carcinoma, lung cancer and bladder cancer. However, the effect of DFO on esophageal squamous cell carcinoma (ESCC) remains unclear. Here, we report that DFO-treated ESCC cells show strong anti-tumorigenic properties, such as inhibition of cell proliferation, induction of cell cycle arrest, and promotion of apoptosis. Mechanistically, DFO significantly activated ERK1/2 signaling, which is reactive oxygen species (ROS)-dependent...

Lung has critic function in gas exchange, supplying oxygen to all cells. Rapid metastasis and the high rate of mortality characterises lung cancer. There are two types of this disease, small cell and non-small cell, which differs from each other according to histopathologic features. To date, many therapeutic approaches have been developed to destroy this deadly type of cancer, which one of them is mRNA targeted therapies through miRNA. miRNAs are 19-25 base paired molecules be able to suppress and destruct mRNA and found to be involved in development and progression of lung cancer...

Purpose Both temozolomide (TMZ) and poly (ADP-ribose) polymerase (PARP) inhibitors are active in small-cell lung cancer (SCLC). This phase II, randomized, double-blind study evaluated whether addition of the PARP inhibitor veliparib to TMZ improves 4-month progression-free survival (PFS). Patients and Methods A total of 104 patients with recurrent SCLC were randomly assigned 1:1 to oral veliparib or placebo 40 mg twice daily, days 1 to 7, and oral TMZ 150 to 200 mg/m2 /day, days 1 to 5, of a 28-day cycle until disease progression, unacceptable toxicity, or withdrawal of consent...

Disseminated castration-resistant prostate cancer (CRPC) is a common disease in men that is characterized by limited survival and resistance to androgen-deprivation therapy. The increase in human epidermal growth factor receptor 2 (HER2) signaling contributes to androgen receptor activity in a subset of patients with CRPC; however, enigmatically, HER2-targeted therapies have demonstrated a lack of efficacy in patients with CRPC. Aberrant glycosylation is a hallmark of cancer and involves key processes that support cancer progression...

Oncogenic Kras mutations are one of the most common alterations in non-small cell lung cancer and are associated with poor response to treatment and reduced survival. Driver oncogenes, such as Kras are now appreciated for their ability to promote tumor growth via up-regulation of anabolic pathways. Therefore, we wanted to identify metabolic vulnerabilities in Kras-mutant lung cancer. Using the Kras LSL-G12D lung cancer model, we show that mutant Kras drives a lipogenic gene-expression program. Stable-isotope analysis reveals that mutant Kras promotes de novo fatty acid synthesis in vitro and in vivo...

First-generation epidermal growth factor receptor (EGFR) inhibitors, gefitinib and erlotinib have achieved initially marked clinical efficacy for non-small cell lung cancer (NSCLC) patients with EGFR activating mutations. However, their clinical benefit was limited by the emergence of acquired resistance mutations. In most cases (approximately 60%), the resistance was caused by the secondary EGFR T790M gatekeeper mutation. Thus, it is still desirable to develop novel third-generation EGFR inhibitors to overcome T790M mutation while sparing wild-type (WT) EGFR...

Background: Upregulated expression and aberrant activation of the epidermal growth-factor receptor (EGFR) are found in lung cancer, making EGFR a relevant target for non-small-cell lung cancer (NSCLC). Treatment with anti-EGFR monoclonal antibodies (mAbs) is associated with modest improvement in overall survival in patients with squamous cell lung cancer (SqCLC) who have a significant unmet need for effective treatment options. While there is evidence that using EGFR gene copy number, EGFR mutation, and EGFR protein expression as biomarkers can help select patients who respond to treatment, it is important to consider biomarkers for response in patients treated with combination therapies that include EGFR mAbs...

Animal studies have shown that polyunsaturated fatty acids (PUFAs) have antineoplastic and anti-inflammatory properties. Results from epidemiologic studies on specific types of PUFAs for lung cancer risk, however, are inconclusive. We prospectively evaluated the association of specific types of dietary PUFA intakes and lung cancer risk in two population-based cohort studies, the Shanghai Women's Health Study (SWHS) and Shanghai Men's Health Study (SMHS) with a total of 121,970 study participants (i.e., 65,076 women and 56,894 men)...

Lung cancer remains the leading cause of cancer death throughout the world. Despite new chemotherapeutic, immunomodulating and molecularly targeted agents, patients with locally advanced or metastatic disease still have a poor prognosis. This trial looked to combine antiangiogenic therapy with a first-line cytotoxic chemotherapy doublet, hoping to extend median progression-free survival (PFS) while minimizing toxicity in patients with advanced nonsquamous non-small-cell lung cancer (NSCLC). In this single institution, single-arm study, 51 patients (age >18 yo) were followed from 2007 to 2012...

Like other tumors, lung cancer must induce angiogenesis as it grows. Hypoxia-inducible factor 1α (HIF-1α) is the inducible subunit of the HIF-1 transcription factor that regulates genes involved in the response to hypoxia, some of which contributes to angiogenesis. Vascular endothelial growth factor (VEGF) is one of the genes upregulated by HIF-1 and is the primary cytokine in relation to angiogenesis. In this study we tested whether aberrant activation of hypoxia inducible factor-1α/vascular endothelial growth factor (HIF-1α/VEGF) pathway correlates with response to radiotherapy and examined the response of lung cancer cells to hypoxia in vitro...
