We have previously reported that dihydroartemisinin is found to have a potent ability in influencing lymphatic endothelial cell migration and tube formation. In this study, we investigated the effect of artemisinin on tumor growth, lymphangiogenesis, metastasis and survival in mouse Lewis lung carcinoma (LLC) models. We found that orally administered(More)
OBJECTIVES Tumor-associated macrophages have been implicated in promoting tumor growth, progression and metastasis. However, the activated phenotype (M1 or M2) of tumor-associated macrophages remains unknown in solid tumors. Therefore, this study examined the density and prognostic significance of M2-polarized tumor-associated macrophages in lung(More)
Our previous study demonstrated that the overexpression of solute carrier family 22 member 18 (SLC22A18) in human non-small cell lung cancer (NSCLC) tissues might be associated with tumor progression and patients' prognosis. The aim of this study was to investigate the molecular mechanisms underlying its roles in NSCLC. As a result, bioinformatics analysis(More)
BACKGROUND Matrix metalloproteinase-9 (MMP-9) is an important member of the matrix metalloproteinase family and is considered to be involved in the invasion and metastasis of cancer cells. This study analyzed the expression of MMP-9 in colon cancer patients and the relationship between this expression and clinicopathological features and survival. METHODS(More)
The expression levels of the RNA-binding protein Hu antigen (HuR) and vascular endothelial growth factor-C (VEGF-C) were examined immunohistochemically in 81 non-small cell lung cancers (NSCLC) and 15 benign human lung tissues. HuR showed a nuclear overexpression in 82.7% (67/81) of NSCLC specimens. Cytoplasmic immunoreactivity for HuR was observed in 45.7%(More)
Tumor-associated macrophages (TAMs) have been implicated in promoting tumor progression and invasion. The onset and maintenance of tumor angiogenesis and lymphangiogenesis also seem to be partly driven by a group of polarized alternatively activated macrophages (aaMphi) in lung adenocarcinoma. Here, the aaMphi and classically activated macrophages (caMphi)(More)
Since induction of hTERT expression and subsequent telomerase activation play a critical role in the multistep process of tumorigenesis, a better understanding of hTERT regulation may provide not only a rationale for the molecular basis of cancer progression but also a path to the development of cancer prevention. The c-Myc oncoprotein can function(More)
BACKGROUND Neutrophil-to-lymphocyte ratio (NLR) has been shown to be a prognostic indicator in several types of cancer. We aimed to investigate the association between NLR and survival in surgery-treated non-small cell lung cancer (NSCLC) patients. STUDY DESIGN This large retrospective study included 1,245 patients who underwent initial surgery for stage(More)
Despite several decades of intensive effort to improve the imaging techniques for lung cancer diagnosis and treatment, primary lung cancer is still the number one cause of cancer death in the United States and worldwide. The major causes of this high mortality rate are distant metastasis evident at diagnosis and ineffective treatment for locally advanced(More)
A recent study showed that miR-26a is downregulated in hepatocellular carcinoma tissues and that this downregulation is an independent predictor of survival. Interestingly, the same study also reported that miR-26a downregulation causes a concomitant elevation of IL-6 expression. Because miR-26a expression was found to be transcriptionally downregulated by(More)
