BACKGROUND The co-existence of coronary heart disease (CHD) and lung cancer is increasing in an increasingly aging population. The aim of this study was to evaluate patient outcome from combined off-pump coronary artery bypass graft (CABG) surgery and lung resection in patients more than 50 years-of-age. MATERIAL AND METHODS A retrospective clinical study of 23 patients with a mean age of 70.2±8.4 years (range, 51-86 years) included 18 men and five women with CHD and lung cancer who underwent a single operation with combined off-pump CABG surgery and lung resection, for non-small cell lung cancer (NSCLC) (n=22) and small cell lung cancer (n=1)...

Cancer stem cells (CSCs) contribute to multidrug resistance, tumor recurrence and metastasis, making them prime therapeutic targets. Their ability to differentiate and lose stem cell properties makes them challenging to study. Currently, there is no simple assay that can capture and trace the dynamic phenotypic changes on the CSC surface. Here, we report rapid discrimination of breast CSCs from non-CSCs using a nanoparticle-fluorescent-protein based sensor. This nanosensor was employed to discriminate CSCs from non-CSCs, as well CSCs that had differentiated in vitro in two breast cancer models...

The subtypes of distant-organ metastasis led to treatment failure and poor prognosis are major obstacles in the management of patients with advanced breast cancer (BCa). Emerging evidences demonstrated that exosomes act as mediators for intercellular communication between various types of cells in the local tumor microenvironment. The present study aims to investigate whether BCa-derived exosomes are capable of cell-cell transferring miR-222 for BCa metastatic progression. Results showed that exosomal miR-222 is highly expressed in BCa patients with lymphatic metastasis...

The rate of segmental resection for early stage non-small cell lung carcinoma (NSCLC) is increasing. However, the indications remain controversial. The aim of this study is to analyze the preliminary results of thoracoscopic segmental resection in early stage NSCLC in terms of morbidity, oncological validity and survival. We report the preliminary results of a consecutive series of 226 thoracoscopic segmentectomies for suspicion of early stage NSCLC. PATIENTS AND METHODS: Between 2007 and 2016, we performed 322 thoracoscopic anatomical sublobar resections (ASLR)...

Gallbladder cancer (GBC) is the most common malignancy of the biliary tract and its molecular pathogenesis is poorly understood. Aberrant expression of epithelial membrane protein-3 (EMP3) was reported in different kinds of cancers. Our study aimed to explore the elusive functional roles and the underlying molecular mechanisms of EMP3 with respect to GBC progression. The results showed that human GBC tissues exhibited decreased levels of EMP3 compared with non-malignant tissues. Kaplan-Meier analysis indicated that low expression of EMP3 was associated with poor prognosis of GBC patients...

It is increasingly recognized that many human carcinomas express immunoglobulin (Ig) molecules that are distinct from B-cell-derived Ig and play important roles in cancer initiation, progression, and metastasis. However, the molecular mechanisms underlying the functions of cancer-derived Ig remain elusive. Here, we report that lung squamous cell carcinoma (LSCC) cells frequently express high levels of cancer IgG (CIgG) that is specifically recognized by a monoclonal antibody RP215. RP215 recognizes CIgG via a novel epitope that involves an N-glycan modification at a non-consensus site within the CH 1 domain...

BACKGROUND AND AIM: Studies have reported that Zinc finger E-box binding homeobox 1 antisense 1 (ZEB1-AS1) is overexpressed in many malignant tumors. However, the sample size in those studies was limited, so the clinicopathological and prognostic value of ZEB1-AS1 in solid tumors remains undetermined, Accordingly, the aim of this meta-analysis was to evaluate the relationship between the expression of lncRNA ZEB1-AS1 and clinicopathological characteristics and prognosis in patients with solid tumors...

Hepatocellular carcinoma (HCC) is the fifth most common cancer around the world, along with high mortality and metastasis rate. Our present study aimed to explore the role of LncRNA HOTAIR in the progression of HCC. Our data showed that HOTAIR was overexpressed in HCC tissues and cell lines (Huh7, Hep3B, HepG2, MHCC97H). Overexpressed HOTAIR promoted invasion and migration of HCC cells (Huh7) by enhancing epithelial-mesenchymal transition (EMT). Besides that, miR-23b-3p was predicted to be a target of HOTAIR and decreased expression of miR-23b-3p was observed in HCC tissues and cell lines...

Molecular targeted therapy for specific genes is an emerging research. Retinoic Acid Receptor (RAR-β) is a key tumor suppressor which is found to be lost drastically during much cancer progression. We hence, analyzed the expression level of RAR-β gene during B(a)P induced lung cancer development in mice and studied the lung cancer targeted action of All Trans Retinoic Acid (ATRA) in DOTAP liposomal formulation. The effect of its treatment on lung cancer was determined by histopathological analysis. RAR-β gene expression was assessed by RT-PCR and qPCR...

Alternative splicing is evolving as an eminent player of oncogenic signaling for tumor development and progression. Mucin 4 (MUC4), a type I membrane-bound mucin, is differentially expressed in pancreatic cancer (PC) and plays a critical role in its progression and metastasis. However, the molecular implications of MUC4 splice variants during disease pathogenesis remain obscure. The present study delineates the pathological and molecular significance of a unique splice variant of MUC4, MUC4/X, which lacks the largest and polymorphic exon 2, along with exon 3...

Epithelial ovarian cancer (EOC) is the most lethal gynecological malignancy, and the sixth leading cause of cancer related death in women overall. Despite improved surgical techniques and advances in chemotherapy, mortality hardly decreased over the last twenty years. The major problem is that (micro)metastases persevere in the abdominal cavity, causing incurable tumor recurrence. Therefore, there is an imminent need for new therapeutic strategies. Oligonucleotide (ON) based therapies such as RNA interference (RNAi) provide the possibility to specifically address disease-related pathways...

Cadherin switch is an initiating factor of epithelial-mesenchymal transition (EMT) and is intimately correlated with cancer metastatic potential; however, its underlying mechanisms remain unclear. Here, using a transforming growth factor-β (TGF-β)-induced EMT model, we provide explicit evidence that CD146, with elevated expression and activity in a variety of cancers, is a key factor involved in the cadherin switch. We show that CD146 can be induced by TGF-β signaling. Moreover, CD146 expression is positively correlated with the activation levels of STAT3/Twist and ERK pathways...

BACKGROUND: The glycan moieties sialyl-Lewis-X and/or -A (sLeX/A ) are the primary ligands for E-selectin, regulating subsequent tumor cell extravasation into distant organs. However, the nature of the glycoprotein scaffolds displaying these glycans in breast cancer remains unclear and constitutes the focus of the present investigation. METHODS: We isolated glycoproteins that bind E-selectin from the CF1_T breast cancer cell line, derived from a patient with ductal carcinoma...

Dysregulation of microRNAs has been demonstrated to be involved in a variety of biological events related to cancer, including proliferation, metastasis, angiogenesis and immune escape. miR-616-3p is located on the chromosome region 12q13.3, however, its potential role and clinical implications in gastric cancer remain poorly understood. The current study aimed to investigate the potential role of miR-616-3p in gastric cancer. The results showed that miR-616-3p was up-regulated in cancer tissues. Higher expression of miR-616-3p in tumor tissues also predicted poor prognosis...

The direct anti-proliferative and pro-apoptotic effects of local anesthetics have been well documented in various cancers. However, whether local anesthetics affect cancer metastasis and their underlying molecular mechanisms are not well understood. In this work, we show that ropivacaine at the clinically relevant concentration significantly inhibits esophageal cancer cell migration. Interestingly, ropivacaine at the same concentration does not display inhibitory effects on esophageal cancer cell growth and survival...

Platelets play a crucial role in the survival of metastatic cells in the blood circulation. Interaction of tumor cells with platelets leads to the production of plethoric factors among which our review will focus on lysophosphatidic acid (LPA) because platelets are the highest producers of this bioactive lysophospholipid in the organism. LPA promotes platelet aggregation and blocking platelet function leads to inhibition of breast cancer cell metastasis through decreased LPA signaling. Autotaxin (ATX), a lysophospholipase D responsible for basal concentration of LPA in blood, was detected in platelet α-granules...

Recent studies have confirmed that IL-6/GP130 targets are closely associated with tumor growth, metastasis and drug resistance. 5-Fluorouracil (5-FU) is the most common chemotherapeutic agent for colon cancer but is limited due to chemoresistance and high cytotoxicity. Bazedoxifene (BZA), a third-generation selective estrogen receptor modulator, was discovered by multiple ligand simultaneous docking and drug repositioning approaches to have a novel function as an IL-6/GP130 target inhibitor. Thus, we speculated that in colon cancer, the anti-tumor efficacy of 5-FU might be increased in combination with IL-6/GP130 inhibitors...
