The present study identified that fibroblast growth factor receptor 3 (FGFR3) was significantly upregulated in bone metastasis of lung adenocarcinoma. RNA interference (RNAi) is a powerful approach for treating a wide range of human diseases, including cancer, through downregulating the expression of selected genes. In the present study, the invasiveness of A549 cells cultured in vitro was altered by small interfering (si)RNA targeting FGFR3, and the regulatory effect of silencing FGFR3 on the expression levels of E-cadherin and matrix metalloproteinase (MMP)9 was investigated...

Choriocarcinoma is a human chorionic gonadotrophin (HCG)-secreting tumor that comprises vascular channels. It has a tendency for widespread metastasis, common sites for which include the lung, vagina, brain, liver, bone, intestine, and kidney. We describe a 30-year-old female who presented with hepatitis-like features and bilateral diminution of vision, and subsequently developed hemothorax and hemoperitoneum-all rare and seemingly unrelated manifestations which were finally attributable to metastases from gestational choriocarcinoma...

BACKGROUND: Activated protein C/endothelial protein C receptor (APC/EPCR) axis is physiologically involved in anticoagulant and cytoprotective activities in endothelial cells. Emerging evidence indicates that EPCR also plays a role in breast stemness and human tumorigenesis. Yet, its contribution to breast cancer progression and metastasis has not been elucidated. METHODS: Transcriptomic status of EPCR was examined in a cohort of 286 breast cancer patients. Cell growth kinetics was evaluated in control and EPCR and SPARC/osteonectin, Cwcv, and kazal-like domains proteoglycan (SPOCK1/testican 1) silenced breast cancer cells in 2D, 3D, and in co-culture conditions...

Long non-coding RNAs (lncRNAs) with more than 200 nuleotides, have been explored to participate in various cancer types including osteosarcoma (OS), which is the most common kind of primary bone tumors with high morbidity in infants and adolescents. These oncogenic or tumor suppressive lncRNAs regulate OS pathogenesis, such as cell growth, proliferation, invasion, migration, metastasis and cell apoptosis, serve as independent prognostic biomarkers or play a significant role in multidrug resistance (MDR) in OS cells...

Osteosarcoma is the most common primary bone tumor characterized by high risk of metastasis, thus presents with an overall survival rate of 60%, despite the use of chemotherapy and surgery. Metastasis‑associated lung adenocarcinoma transcript 1 (MALAT‑1) has been reported to upregulated and epigenetically regulate the metastasis in osteosarcoma; however, the regulatory mechanisms of MALAT‑1 expression remain unclear. In the current study, significant upregulation of MALAT‑1 was observed subsequent to exposure to low concentrations of 17β‑estradiol (E2) in U2OS cells...

BACKGROUND: Most prevalent esophageal neoplasm is squamous cell carcinoma and adenocarcinoma. Other tumors are uncommon and poorly studied. Primary neuroendocrine esophageal neoplasm is a rare carcinoma and most of its therapy management is based on lung neuroendocrine studies. Neuroendocrine tumors can be clustered in the following subtypes: high grade (small cell carcinoma or large cell carcinoma) and low grade (carcinoids). OBJECTIVE: The present study aims to assess clinical and pathological neuroendocrine esophageal tumors in a single oncologic center...

Despite the clinical importance of metastasis to the skeleton, the diagnostic tools for early detection and monitoring of bone metastasis lack sensitivity and specificity. We evaluated a promising new serum biomarker, the soluble form of the Receptor of Advanced Glycosylated End-products (sRAGE). sRAGE is involved in the Wnt-signaling pathway, and has been reported to reduce the risk of cancer. We investigated the diagnostic potential of sRAGE to improve the detection and monitoring of bone metastasis. We measured sRAGE in the serum of control healthy subjects, patients with primary tumors and patients with bone metastasis...

Tumor metastasis is defined as the spread of tumor cells from one organ or part to another that is not directly connected to it, which significantly contributes to the progression and aggravation of tumorigenesis. Because it always involves multiple organs, the metastatic process is difficult to study in its entirety. Complete identification of the genes related to this process is an alternative way to study metastasis. In this study, we developed a computational method to identify such genes. To test our method, we selected breast cancer bone metastasis...

Breast cancer is one of the most common malignant neoplasms diagnosed in females worldwide. Bone morphogenetic proteins (BMPs), which belong to the TGF-β superfamily, regulate a wide range of cellular responses including cell proliferation, differentiation, adhesion, migration and apoptosis in breast cancer. BMPs can bind to type I and II serine/threonine kinase receptors to regulate cell proliferation, invasion, migration, and apoptosis. Type I receptors are expressed in various breast cancer cell lines and primary tumor samples...

The Wnt/β-catenin signaling is abnormally activated in the progression of hepatocellular carcinoma (HCC). BCL9 is an essential co-activator in the Wnt/β-catenin signaling. Importantly, BCL9 is absent from tumors originating from normal cellular counterparts and overexpressed in many cancers including HCC. But the mechanism for BCL9 overexpression remains unknown. Ample evidence indicates that hypoxia inducible factors (HIFs) play a role in the development of HCC. It was found in our study that BCL9 was overexpressed in both primary HCC and bone metastasis specimens; loss of BCL9 inhibited the proliferation, migration and angiogenesis of HCC; and that that hypoxia mechanically induced the expression of BCL9...

Bone metastasis is common during breast cancer progression. Matrix metalloproteinase-2 (MMP-2) is significantly associated with aggressive breast cancer and poorer overall survival. In bone, tumor or host derived MMP-2 contributes to breast cancer growth and does so by processing substrates including type I collagen and transforming growth factorβ (TGFβ) latency proteins. These data provide strong rationale for the application of MMP-2 inhibitors to treat the disease. However, in vivo, MMP-2 is systemically expressed...
