We report a novel series of quinoxaline derivatives from which agents with antiproliferative activity have been identified. Two ethyl 3-(arylethynyl)quinoxaline-2-carboxylates demonstrated substantial antiproliferative activity against both human non-small cell lung carcinoma (A549) and glioblastoma (U87-MG) cell lines. Pyrido[4,3-b]quinoxalin-1(2H)-ones demonstrated poor activity against A549 and U87-MG cell lines. Three of the derivatives in ethyl 3-(arylethynyl)quinoxaline-2-carboxylate series demonstrated substantial antiproliferative activity...

BACKGROUND AND AIMS: BCL2L10 is an apoptosis-related member of the BCL-2 protein family. The role of BCL2L10 in the pathogenesis of hepatocellular carcinoma (HCC) is poorly understood. This study was aimed to investigate the function and underlying mechanisms of BCL2L10 in HCC. METHODS: BCL2L10 expression in human HCC and corresponding adjacent normal tissues was investigated by quantitative real-time PCR and western blot. The biological functions of BCL2L10 in HCC cell lines were determined by cell viability, colony formation, cell apoptosis, cell cycle and cell metastasis assays, and in vivo by tumorigenicity and lung metastasis assays in nude mice...

Cancer stem-like cells (CSCs) exist in tumor tissues composed of heterogeneous cell population and are characterized by their self-renewal capacity and tumorigenicity. Many studies demonstrate that eradication of CSCs prevents development and recurrences of tumor; yet, molecules critical for the maintenance of CSCs have not been completely understood. We previously reported that Semaphorin3A (Sema3a) knockdown suppressed the tumorigenicity and proliferative capacity of Lewis lung carcinoma (LLC) cells. Therefore, we identified Sema3a as an essential factor for the establishment or maintenance of CSCs derived from LLC (LLC-stem cell)...

Small cell lung cancer (SCLC) is known for its metastatic potential. The most common sites are liver, adrenal, bone and brain. We report a case of a 37year old female patient, diagnosed with SCLC, presenting with gingival metastasis, an unusual metastatic site. Radiation therapy to the metastatic lesion to a dose of 20 Gray in 5 fractions over 5days was delivered which achieved haemostasis and good palliation. However, the patient expired in 2months owing to systemic metastasis.

Cryptococcosis is a fungal infection caused by Cryptococcus spp. that enters the body via inhalation. This ubiquitous yeast has gained notoriety as an opportunistic pathogen in the immunosuppressed population. The authors report a case of a previously-well adult male presented with left-sided weakness. Imaging demonstrated a pulmonary mass and 2 contrast-enhancing intracranial lesions-all features suggestive of a primary lung carcinoma with brain metastases. However, further investigations confirmed disseminated cryptococcosis, without evidence of malignancy...

To evaluate the potential of cell-penetrating peptide-based delivery of apoptosis-inducer gene in cancer therapy, a modified HIV-1 TAT peptide (dimerized TAT peptide, dTAT) was studied. The dTAT and plasmid DNA (pDNA) complexes (dTAT-pDNA) were condensed using calcium chloride (dTAT-pDNA-Ca(2+)). This simple nonviral formulation approach showed high levels of gene expression in vitro without any cytotoxicity. In mouse studies, a single intratracheal (IT) aerosol spray or 2 intravenous (IV) injections of the dTAT, apoptosis-inducer gene, angiotensin II type 2 receptor (AT2R), and Ca(2+) complexes (dTAT-pAT2R-Ca(2+)) significantly attenuated the acutely growing mouse Lewis lung carcinoma allografts in mouse lungs...

Ubiquitin-Specific Proteases (USPs) are deubiquitinating enzymes frequently deregulated in human malignancies. Here, we show that USP54 is overexpressed in intestinal stem cells and demonstrate that its downregulation in colorectal carcinoma cells impedes tumorigenesis. We have generated mutant mice deficient for this deubiquitinase, which are viable and fertile, and protected against chemically-induced colorectal carcinoma. Furthermore, we show that USP54 is upregulated in human colon cancer and associates with poor prognosis...

Break-apart ALK FISH probe is the FDA approved approach for detection of ALK rearrangements in lung carcinoma patients who may benefit from ALK kinase inhibitors. The FISH assay can be technically challenging and difficult to interpret. ALK immunohistochemistry and next generation sequencing have been proposed as alternative approaches. In this study, we compared various ALK -FISH patterns to next -generation sequencing (NGS) for gene fusion detection, ALK immunohistochemistry (IHC) and tumor responses to crizotinib...

Even with all improvements in both diagnostic and therapeutic techniques, lung cancer remains as the most lethal and prevalent cancer in the world. Therefore, new therapeutic drugs and new strategies of drug combination are necessary to provide treatments that are more efficient. Currently, standard therapy regimen for lung cancer includes platinum drugs, such as cisplatin, oxaliplatin, and carboplatin. Besides of the better toxicity profile of oxaliplatin when compared with cisplatin, peripheral neuropathy remains as a limitation of oxaliplatin dose...

OBJECTIVE: Combined pulmonary fibrosis and emphysema (CPFE) is a newly defined entity that comprises upper lobe emphysema and lower lobe fibrosis. Patients with CPFE are at high risk for lung cancer and have poor prognoses. To investigate the clinical and pathological characteristics of lung cancer with CPFE, lung cancers with CPFE and Non-CPFE interstitial lung disease (ILD) were reevaluated by 2015 WHO classification and compared. METHODS: A total of 60 patients with histologically proven lung cancer were selected from the database of two institutional medical centers...

BACKGROUND: Renal cell carcinoma (RCC) is among the 10 most common cancers in both men and women. It comprises 2-3% of all malignancies. The most common site for metastasis from RCC is the lung (50% of patients), followed by the skeleton (20% to 50% of patients). METHODS: We retrospectively reviewed our consecutive series of 63 patients surgically treated for spinal metastases from RCC. The surgical treatment for spinal metastases varied in each patient. Factors influencing the choice of surgery included age, disease status, symptoms, morbidity of the patient, the location, the number of repetitive lesions and the existence of extra-osseous metastases...

This study was conducted to investigate whether polymorphisms of genes involved in glycolysis are associated with the prognosis of patients with non-small cell lung cancer (NSCLC) after surgical resection. Forty-four single nucleotide polymorphisms (SNPs) of 17 genes in glycolytic pathway were investigated in a total of 782 patients with NSCLC who underwent curative surgical resection. The association of the SNPs with overall survival (OS) and disease free survival (DFS) were analyzed. Among the 44 SNPs investigated, four SNPs (ENO1 rs2274971A > G, PFKM rs11168417C > T, PFKP rs1132173C > T, PDK2 rs3785921G > A) were significantly associated with survival outcomes in multivariate analyses...

Lung cancer is the most common solid tumor and the leading cause of cancer-related death worldwide. Non-small cell lung cancer (NSCLC) represents the major histological subtype and accounts for about 80 % cases of lung cancer cases. Recently, lncRNA lncTCF7 was identified, which is highly expressed in hepatocellular carcinoma (HCC) tumors and liver cancer stem cells (CSCs). However, the role of lnTCF7 in NSCLC remains largely unknown. In this study, Gain- and loss-of-function studies demonstrated the critical role of lncTCF7 in promoting invasion and self-renewal in NSCLC cells...

Patients with lung adenocarcinoma may benefit from recently developed molecular targeted therapies. However, analogous advanced treatments are not available for patients with lung squamous cell carcinoma (lung SCC). The survival rate of patients with the advanced stage of lung SCC remains poor. Exploration of novel lung SCC oncogenic pathways might lead to new treatment protocols for the disease. Based on this concept, we have identified microRNA- (miRNA) mediated oncogenic pathways in lung SCC. It is well known that miR-145-5p (the guide strand) functions as a tumor suppressor in several types of cancer...

Lung cancer is the leading cause of cancer-related death, and 87% of these deaths are directly attributable to smoking. Using three-dimensional cultures of primary human bronchial epithelial cells, we demonstrated that loss of adherens junction protein, epithelial cadherin, and the aberrant interaction of its adherens junction binding partner, p120-catenin (p120ctn), with the cytoplasmic tail of apical mucin-1 (MUC1-CT) represent initiating steps in the epithelial-to-mesenchymal transition. Smoke provoked the rapid nuclear entry of p120ctn in complex with MUC1-CT that was inhibited using the MUC1-CT inhibitory peptides, PMIP and GO-201...

BACKGROUND: Sarcomatoid urothelial carcinoma (SUC) is a rare malignant neoplasm of the urinary bladder comprising 0.2-0.6 % of all histological bladder tumor subtypes. It presents as a high-stage malignancy and exhibits aggressive biological behavior, regardless of the treatment employed. It is defined as histologically indistinguishable from sarcoma and as a high-grade biphasic neoplasm with malignant epithelial and mesenchymal components. The mean age of patients presenting with SUC is 66 years, and the male-to-female ratio is 3:1...
