miR-21 induces epithelial-mesenchymal transition (EMT) of human cholangiocarcinoma (CCA) cells. However, the mechanism by which this occurs remains unclear. In the present study, high throughput platform was employed to detect the genes that are differential expressed in QBC939 cells transfected with a hsa-miR-21 antagomir or control vectors. The EMT-related Krüppel-like factor 4 (KLF4) gene was downregulated after miR-21 was knocked down. Overexpression of miR-21 upregulated KLF4, Akt, ERK and mesenchymal cell markers (N-cadherin and vimentin), downregulated the expression of epithelial cell marker E-cadherin and reduced cell migration and invasion...

The diagnosis and treatment for colon cancer have been greatly developed, but the prognosis remains unsatisfactory. There is still a great clinical need to explore new efficacious drugs for colon cancer treatment. Tetrandrine (Tet) is a bis-benzylisoquinoline alkaloid. It has been shown that Tet may be a potential candidate for cancer treatment, but the explicit mechanism underlying this activity remains unclear. In this study, we investigated the anticancer activity of Tet in human colon cancer cells and dissected the possible mechanism...

Müllerian inhibiting substance/anti-Müllerian hormone (MIS/AMH) has been suggested as a biotherapeutic agent in gynecological cancers that highly express the MIS/AMH type II receptors (MISRII/AMHRII) but the anticancer mechanisms by which MIS/AMH acts are not fully understood. Our experiments show that MIS/AMH inhibits ovarian cancer by deregulating the Wnt signal pathway via the β-catenin interacting protein (ICAT). MIS/AMH inhibition of ICAT by small interfering RNAs (siRNA) decreased ICAT driven ovarian cancer cell viability as measured by the methylthiazoltetrazolium assay, reversed cell cycle arrest and annexin V expression and diminished migration by scratch wound assay...

Breast cancer is the leading cause of cancer death among women. Paclitaxel, a mitotic inhibitor, is highly effective in the treatment of breast cancer. However, development of resistance to paclitaxel limits its clinical use. Identifying new compounds and new strategies that are effective against breast cancer, in particular drug-resistant cancer, is of great importance. the aim of the present study was to explore the potential of a next-generation taxoid, SB-T-121205, in modulating the proliferation, migration and invasion of paclitaxel-resistant human breast cancer cells (MCF-7/PTX) and further evaluate the underlying molecular mechanisms...

Cisplatin treatment some times leads to chemoresistance, which is now acknowledged partially due to the inductive expression of progesterone receptor membrane component (PGRMC)1 in ovarian cancer cells. PGRMC1 enhances autophagy, activates cytochrome p450, and inveigles signaling pathways to promote cell survival and reduce the effect of drug treatments. In this study, we give first line evidence that hyperoside inhibits cell viability, triggers autophagy and apoptosis in ovarian cancer cell lines. Mechanistically, PGRMC1-dependent autophagy was utilized by hyperoside to induce apoptotic cell death...

Paracrine and long-range signaling via extracellular vesicles, such as exosomes and microvesicles, is deemed crucial for tumorigenesis, invasion and spread of solid tumors. The ESCRT machinery (endosomal sorting complexes required for transport) and Rab-proteins act as key players in vesicular trafficking and secretion. Yet, their role in prostate cancer (PCa) is unknown. Therefore, this study aimed to elucidate the relevance of these components in PCa. In silico reanalysis of genes with known involvement in vesicular trafficking and secretion in an existing microarray dataset revealed low expression of RAB27A, RAB27B and VPS36 to be predictive for reduced BCR-free survival in patients with localized PCa (p=0...

Tumor necrosis factor α induced protein 3 (TNFAIP3) is a protein that is induced by TNF-mediated NF-κB activation and has a dual function in regulating NF-κB. TNFAIP3 is associated with inflammatory carcinogenesis in many cancer types. However, the clinical significance of TNFAIP3 expression and function in esophageal squamous cell carcinoma (ESCC) has not yet been reported. We examined 149 ESCC tissue specimens to determine the clinical significance of TNFAIP3 by immunohistochemistry. Western blot analyses were used to detect TNFAIP3 expression in TE-1, TE-8, TE-15 and KYSE-70 ESCC cells and in Het-1A, a non-cancerous esophageal cell line...

Malignant pleural mesothelioma (MPM) is a rare aggressive cancer of the pleura primarily associated with prior exposure to asbestos. The current standard of care for patients suffering from MPM is a combination of cisplatin and pemetrexed (or alternatively cisplatin and raltitrexed). Most patients, however, die within 24 months of diagnosis. New therapies are therefore urgently required for this disease. Inflammation is thought to be a key element in the pathogenesis of MPM, and recently Kdm6 family members (Kdm6a and Kdm6b) have been identified as playing important roles in inflammatory processes...

Hepatocellular carcinoma is the second most common cause of cancer-related deaths worldwide. Due to a high propensity to metastasize, active angiogenesis and rapid proliferation, recurrence and poor prognosis are major obstacles for treatment and cure of this disease. However, the detailed mechanisms of how fatty acid synthase (FASN) promotes migration, invasion and healing in tumor cells remain unclear. In the present study, the previous results that FASN was expressed higher in cancer samples than in non-cancerous samples, and influenced migration, invasion of hepatoma carcinoma cells, were verified by immunohistochemistry, tissue microarrays, Transwell assay and wound healing assay...

The mitochondrial deacetylase SIRT3 plays a pivotal role in the initiation and the progression of certain cancers acting as an oncogene. However, in others it acts anti-oncogenically. Its conflicting action is possibly due to the different key proteins it modifies depending on the context of active intracellular signaling pathways in different cancers. SIRT3 is thus a novel target for preventing and treating cancer. In the present study, we explored the function of SIRT3 in non-small cell lung cancer (NSCLC) with the aim of elucidating the underlying mechanisms...

Metastasis is the leading cause of cancer deaths due to the spread of cancer cells through the blood vessels and the subsequent formation of secondary tumors. Metastasizing cancer cells in the human vasculature are called circulating tumor cells (CTCs) and are characterized to express the epithelial cell adhesion molecule (EpCAM). They are further known to survive physiological fluid shear stress (FSS) conditions. However, the effect of FSS on CTC molecular phenotype, such as the epithelial to mesenchymal transition (EMT) and cancer stem cell (CSC) expression, has not been extensively studied...

Resveratrol is known to be an effective chemo-preventive phytochemical against multiple tumor cells. However, the increasing drug resistance avoids the cancer treatment in oral cavity cancer. In this study, we investigated the oral antitumor activity of resveratrol and its mechanism in cisplatin-resistant human oral cancer CAR cells. Our results demonstrated that resveratrol had an extremely low toxicity in normal oral cells and provoked autophagic cell death to form acidic vesicular organelles (AVOs) and autophagic vacuoles in CAR cells by acridine orange (AO) and monodansylcadaverine (MDC) staining...

Osteosarcoma (OS) has a high degree of chromosomal instability and total copy number (CN) changes. We examined 58 human OS samples including 40 primary tumors, 11 explants, and 7 cell lines using single nucleotide polymorphism (SNP) arrays, and revealed that 70% of the samples had one or more recurrent CN-neutral loss of heterozygosity (CNN‑LOH) also known as uniparental disomy (UPD). Importantly, 17% of the samples showed prominent homozygous deletion of 3q13.31, suggesting its role in tumorigenesis. We identified and characterized two novel lncRNAs, LOC285194 and BC040587, within this genomic locus, strongly suggesting their tumor suppressor activity...

Malignant mesothelioma is a major asbestos-related cancer with prolonged time lapse from the first exposure of asbestos to the development of mesothelioma. Most of mesothelioma patients show very poor prognosis, thus, an urgent improvement of its treatment is required by development of novel therapeutic strategies. RNA interference (RNAi) is a powerful tool in post-genomic research and cancer therapy through inhibition of gene expression. In the present study, we analyzed the function of PIM1 on mesothelioma cell lines with its knockdown by siRNA transfection...

Medicinal plants are affluent sources of several effectual natural drugs. Among them cordycepin which is extracted from Cordyceps militaris is a hopeful chemotherapy agent due to its extensive anti-inflammatory, anti-proliferative, antioxidant, and antitumor characteristics. This study investigated the efficacy of cordycepin in the context of human gastric cancer SGC‑7901 and searched for the cell death procedure. Cordycepin incorporates mitochondrial-mediated apoptosis in SGC‑7901 cells with the help of regulating mitochondrial extrinsic pathways by inhibition of A3AR and drive activation of DR3, which promote the activation of PI3K/Akt protein expression as well as collapse of mitochondrial membrane potential (MMP)...

Malignant glioma is the most aggressive brain tumor. Hypoxic condition has been explored for killing cancer stem cells or drug-resistant tumor cells. This study investigated the effects of hypoxia on autophagic death and the possible mechanisms. Exposure of human malignant glioma U87-MG cells to cobalt chloride (CoCl2) increased cellular hypoxia-inducible factor-1α levels and concurrently decreased cell viability concentration- and time-dependently. In parallel, treatment with CoCl2 suppressed proliferation of human U87-MG cells...

The effect of resveratrol on various human cancer cells was investigated with special focus on apoptotic cell death, in an attempt to further characterize its mechanism of action. There were great differences in the anti-viability effect of resveratrol between different types of human cancer cells. While the inhibition of cell viability by resveratrol was marked in U937 and MOLT-4 leukemia cells, resveratrol moderately inhibited cell viability in MCF-7 breast, HepG2 liver, and A549 lung cancer cells, and the effect was slight on cell viability in Caco-2, HCT116, and SW480 colon cancer cells...

MicroRNA (miR)-145 has been reported to induce cancer stem cell (CSC) differentiation through down-regulation of the stem cell transcription factors (TFs) that maintain CSC pluripotency. High expression of miR-145 indicates a good prognosis in cancer patients, but its role in cervical cancer stem cells (CCSCs) is not known. We show that expression of miR-145 and core stem cell transcription factors, Sox2, Nanog and Oct4, are associated with the pluripotency of CCSCs, with increased expression of miR-145 after cervical tumorsphere (CT) differentiation...
