Garcinol, a dietary factor obtained from Garcinia indica , modulates several key cellular signaling pathways as well as the expression of miRNAs. Acquired resistance to standard therapies, such as erlotinib and cisplatin, is a hallmark of non-small cell lung cancer (NSCLC) cells that often involves miRNA-regulated epithelial-to-mesenchymal transition (EMT). We used A549 cells that were exposed to transforming growth factor beta 1 (TGF-β1), resulting in A549M cells with mesenchymal and drug resistant phenotype, and report that garcinol sensitized resistant cells with mesenchymal phenotype to erlotinib as well as cisplatin with significant decrease in their IC50 values...

This study was aimed to investigate the anti-tumor, anti-metastasis and immunomodulatory effects of Yifei Tongluo (YFTL), a Chinese herbal formula, in Lewis lung carcinoma mice and to explore the underlying mechanisms. LLC cells were inoculated subcutaneously in C57BL/6 mice to establish the Lewis lung carcinoma model. We observed that YFTL effectively inhibited tumor growth and prolonged the overall survival of tumor-bearing mice. Additionally, YFTL treatment resulted in a significantly decreased number of surface lung metastatic lesions compared with the model control group...

Tumor associated macrophages (TAMs) exert tumor-promoting effects. There have been reports that Estrogen receptors (ERs) are expressed on the infiltrating macrophages of endometriosis, ovarian cancer and lung cancer. However, the role of ERs in macrophages is not well characterized. In this study, we first identified that ERα expression on the macrophages of human endometrial cancer was positively correlated with cancer progression. Conditioned medium from selective ERα agonist-treated M2 macrophages induced the epithelial to mesenchymal transition (EMT) in endometrial cancer cells...

Studies on the mechanism of clear cell renal cell carcinoma (ccRCC) progression are lacking. In this study, TOX3 was identified as a novel cancer suppressor gene in ccRCC. Hypermethylation of CpG probes in the promoter region was associated with the functional loss of TOX3 in ccRCC cancer tissues. Downregulation of TOX3 mRNA was strongly associated with poor clinical outcomes in ccRCC. Immunohistochemistry confirmed TOX3 was downregulated in primary tumors without metastasis (n=126) and further downregulated in primary metastatic tumors (n=23) compared with adjacent noncancerous tissues (n=92)...

Although our previous studies have showed that a novel oncogene, cancer upregulated gene (CUG)2 induced epithelial-mesenchymal transition (EMT), the detailed molecular mechanism remains unknown. Because several lines of evidence documented that Yes-Associated Protein (YAP)1 is closely associated with cancer stem cell (CSC)-like phenotypes including EMT, stemness, and drug resistance, we wondered if YAP1 is involved in CUG2-induced EMT. We herein found that the overexpression of CUG2 increased YAP1 expression at the transcriptional as well as protein levels...

Carcinosarcoma of the upper urinary tract is very rare. In this article, we report a case of upper urinary tract carcinosarcoma with rhabdomyoblastic differentiation showing distinct transition between the epithelial and mesenchymal components confirmed by morphology and immunohistochemistry. An 81-year-old female underwent radical nephroureterectomy under the diagnosis of left ureteral urothelial carcinoma (UC). Multiple invasive tumors showed combined histology with UC and rhabdomyosarcomatous elements (pT2-ureter and pT3-renal pelvis, pN0, u-lt0, ly0, v0, RM0)...

Fractionated ionizing radiation (FIR) is a radiotherapy regimen that is regularly performed as part of lung cancer treatment. In contrast to the growth inhibition caused by DNA damage, immunomodulation in post-irradiated cancer cells is not well documented. Interferon (IFN)-γ confers anticancer activity by triggering both growth inhibition and cytotoxicity. This study investigated the priming effects of FIR with immunomodulation on the anticancer IFN-γ. Cell morphology, cell growth, and cytotoxicity were observed in FIR-treated A549 lung adenocarcinoma...

Paclitaxel is one of the most commonly used drugs for the treatment of nonsmall cell lung cancer (NSCLC). However acquired resistance to paclitaxel, epithelial to mesenchymal transition and cancer stem cell formation are the major obstacles for successful chemotherapy with this drug. Some of the major reasons behind chemoresistance development include increased ability of the cancer cells to survive under stress conditions by autophagy, increased expression of drug efflux pumps, tubulin mutations etc. In this study we found that inhibition of autophagy with chloroquine prevented development of paclitaxel resistance in A549 cells with time and potentiated the effect of paclitaxel by increased accumulation of superoxide-producing damaged mitochondria, with elevated ROS generation, it also increased the apoptotic rate and sub G0/ G1 phase arrest with time in A549 cells treated with paclitaxel and attenuated the metastatic potential and cancer stem cell population of the paclitaxel-resistant cells by ROS mediated modulation of the Wnt/β-catenin signaling pathway, thereby increasing paclitaxel sensitivity...

Objective: Small cell lung carcinoma (SCLC) is considered one of the most aggressive types of lung cancer due to its rapid growth and early metastasis. No tumor markers or therapeutic targets have been demonstrated to be specific or effective in SCLC to date. This study aims to evaluate the potential of Flotillin1 (Flot1) as a target of SCLC treatment. Methods: Flot1 expression level in the tissue of SCLC and other tissue of lung disease was detected using immunohistochemical staining...

Heme oxygenase-1 (HO-1) plays an important role in the progression of several malignancies including breast cancer. However, its role in breast cancer metastasis is still ambiguous. In this study, we observed the effect of HO-1 on mouse mammary carcinoma metastasis using the in vivo tumor metastasis model. Our results revealed that overexpression of HO-1 strongly inhibits the lung metastasis of 4T1 cells. In in vitro analysis, associated indices for Epithelial-mesenchymal transition (EMT), migration and proliferation of 4T1 cells were evaluated...

The Nm23 gene has been acknowledged to play a crucial role in lung cancer metastasis inhibitory cascades controlled by multiple factors. Low expression or allelic deletion of nm23-H1 is strongly linked to widespread metastasis and poor differentiation of non-small cell lung cancer (NSCLC). In this study, nm23-H1 was down regulated in epithelial-mesenchymal transition (EMT) and stemness enhancement under cobalt chloride (CoCl2)-induced hypoxia in NSCLC cells. Moreover, knocking down of nm23-H1 by shRNA apparently promoted hypoxia induced EMT and stemness, which was entirely suppressed via over expression of nm23-H1...

The mesenchymal-to-epithelial transition (MET) gene is altered and becomes a driver mutation in up to 5% of non-small-cell lung cancer (NSCLC). We report our institutional experience treating patients with MET exon 14 skipping (METex14) mutations, including responses to the MET inhibitors crizotinib and cabozantinib. We identified cases of NSCLC with METex14 mutations using an institutionally developed or commercial next-generation sequencing assay. We assessed patient and disease characteristics by retrospective chart review...

Anaplastic Thyroid Cancer (ATC) is an aggressive malignancy with limited therapeutic options and dismal patient survival. We have previously shown MADD to be differentially overexpressed in multiple cancer histologies and to contribute to tumor cell growth and survival. Therefore, we targeted MADD by gene silencing, explored its effect on cellular proliferation and metastases and examined its therapeutic potential in an orthotopic ATC model in athymic nude mice. When compared to untreated control and scramble siRNA, MADD siRNA treatment inhibited the proliferative capacity of 8505C, C643 and HTH7 cells in vitro and 8505C-derived-orthotopic tumor growth in vivo...

BACKGROUND: A hypoxic microenvironment leads to an increase in the invasiveness and the metastatic potential of cancer cells within tumors via the epithelial-mesenchymal transition (EMT) and cancer stemness acquisition. However, hypoxia-induced changes in the expression and function of candidate stem cell markers and their possible molecular mechanism is still not understood. METHODS: Lung cell lines were analyzed in normoxic or hypoxic conditions. For screening among the stem cell markers, a transcriptome analysis using next-generation sequencing was performed...

Induction of cancer stem cell (CSC) characters and epithelial mesenchymal transition (EMT) features are crucial in tumor initiation, progression and metastasis. However, underlying mechanisms remain incompletely understood. Here, we showed that ENPP1 plays an important role in inducing and maintaining EMT phenotypes and CSC features in lung cancer. ENPP1 is upregulated in lung cancer cells. ENPP1-knockdown in lung cancer HCC827 cells and A549 cells resulted in suppressed colonogenic formation, anchorage-independent growth in vitro, and tumorigenicity in vivo...

Long non-coding RNAs (lncRNAs) have been reported to be involved in various pathophysiological processes in many diseases. However, the role and mechanism of lncRNAs in pulmonary fibrosis have not been explicitly delineated. In the present study, we found that lncRNA ZEB1 antisense RNA 1 (ZEB1-AS1) is upregulated in the lungs of BLM-induced rats and TGF-β1-induced RLE-6TN cells, and positively correlated with the levels of ZEB1, an epithelial-mesenchymal transition (EMT) master regulator. Knockdown of ZEB1-AS1 alleviated BLM-induced fibrogenesis, in vivo, via inhibiting EMT progress...

Radon is a naturally occurring radionuclide, which has a wide environmental distributed. It emits multiple high linear energy transfer (LET) alpha particles during radiative decay, and has been regarded as a human carcinogen by the International Agency for Research on Cancer. Currently, residential radon exposure is considered as the second highest cause of lung cancer and the leading cause among nonsmokers. Radon exposure leads to genomic instability, which causes the accumulation of multiple genetic changes and leads to cancer development...
