Aberrant sialylation profiles on the cell surface have been recognized for their potential diagnostic value in identifying the regulation of tumor properties in several cancers, including hepatocellular carcinoma (HCC). Recently, increasing evidence has suggested that the deregulation of microRNA (miRNA) is a common feature in human cancers. In this study, we found obvious up-regulation of ST3GAL6 both in HCC cell lines and in tissue samples. The altered expression of ST3GAL6 was found to correlate with cell proliferation, migration and invasion ability in HCC...

Transforming growth factor beta (TGFβ) signaling in breast cancer is selectively associated with pulmonary metastasis. However, the underlying mechanisms remain unclear. Here we show that Bcl-3, a member of the IκB family, serves as a critical regulator in TGFβ signaling to modulate breast cancer pulmonary metastasis. Bcl-3 expression was significantly associated with metastasis-free survival in breast cancer patients. Bcl-3 deletion inhibited the migration and invasion of breast cancer cells in vitro, as well as breast cancer lung metastasis in vivo...

CD40 is an interesting target in cancer immunotherapy due to its ability to stimulate Th1 immunity via maturation of dendritic cells and to drive M2 to M1 macrophage differentiation. Pancreatic cancer has a high M2 content that has shown responsive to anti-CD40 agonist therapy and CD40 may thus be a suitable target for immune activation in these patients. In this study, a novel oncolytic adenovirus armed with a trimerized membrane-bound extracellular CD40L (TMZ-CD40L) was evaluated as a treatment of pancreatic cancer...

BACKGROUND: Colorectal cancer (CRC) is one of the most common malignancies in the world. microRNA-140-5p (miR-140) has been shown to be involved in cartilage development and osteoarthritis (OA) pathogenesis. Some contradictions still exist concerning the role of miR-140 in tumor progression and metastasis, and the underlying mechanism is uncertain. METHODS: Immunohistochemistry was performed to determine the expressions of ADAMTS5 and IGFBP5 in CRC tissues. Human CRC cell lines HCT116 and RKO were transfected with miR-140 mimic, inhibitor, or small interfering RNA (siRNA) against ADAMTS5 or IGFBP5, respectively, using oligofectamine or lipofectamine 2000...

We propose a multiscale model for the invasion of the extracellular matrix by two types of cancer cells, the differentiated cancer cells and the cancer stem cells. We investigate the epithelial mesenchymal-like transition between them being driven primarily by the epidermal growth factors. We moreover take into account the transdifferentiation program of the cancer stem cells towards the cancer-associated fibroblast cells as well as the fibroblast-driven remodelling of the extracellular matrix. The proposed haptotaxis model combines the macroscopic phenomenon of the invasion of the extracellular matrix by both types of cancer cells with the microscopic dynamics of the epidermal growth factors...

RasGAP SH3-domain-Binding Protein 1 (G3BP1) has been implicated in cell growth, migration, and metastasis of some cancers, yet its function in hepatocellular carcinoma (HCC) remains to be explored. In the present study, we reported that G3BP1 was upregulated in HCC tissues compared with adjacent non-cancerous liver tissues both in mRNA and protein levels, and its high expression was significantly correlated with poor prognosis of HCC patients. Functional analyses demonstrated that forced expression of G3BP1 in HCC cells promoted cell migration, and silenced expression of G3BP1 by RNA interference caused opposite effects...

The G-protein coupled chemoattractant receptor formylpeptide receptor-2 (FPR2 in human, Fpr2 in mice) is expressed by mouse colon epithelial cells and plays a critical role in mediating mucosal homeostasis and inflammatory responses. However, the biological role of FPR2 in human colon is unclear. Our investigation revealed that a considerable number of human colon cancer cell lines expressed FPR2 and its ligands promoted cell migration and proliferation. Human colon cancer cell lines expressing high levels of FPR2 also formed more rapidly growing tumors in immunocompromised mice as compared with cell lines expressing lower levels of FPR2...

Pancreatic cancer is characterized by K-Ras mutations in over 90% of the cases. The mutations make the tumors aggressive and resistant to current therapies resulting in very poor prognoses. Valiant efforts to drug mutant K-Ras and related proteins for the treatment of cancers with Ras mutations have been elusive. The need thus persists for therapies to target and suppress the hyperactive K-Ras mutant proteins to normal levels of activity. Polyisoprenylated cysteinyl amide inhibitors (PCAIs) of polyisoprenylated methylated protein methyl esterase (PMPMEase) were designed to disrupt polyisoprenylated protein metabolism and/or functions...

Gallbladder carcinoma (GBC) is the most common biliary tract malignancy with high mortality. The median survival time is 6 months, and the 5-year survival rate less than 5% for GBC patients. Thus, it is imperative to investigate the molecular mechanisms underlying the pathogenesis of GBC. miR-133a may exert anti-tumor effects on a variety of cancers. However, the role of miR-133a in the pathogenesis of GBC remains unclear. In this study, quantitative real-time polymerase chain reaction (qRT-PCR) showed the miR-133a-3p expression markedly decreased in GBC as compared to adjacent normal tissues...

The role and function of the members of the TGFβ superfamily has been a substantial area of research focus for the last several decades. During that time, it has become apparent that aberrations in TGFβ family signaling, whether through the BMP, Activin, or TGFβ arms of the pathway, can result in tumorigenesis or contribute to its progression. Downstream signaling regulates cellular growth under normal physiological conditions yet induces diverse processes during carcinogenesis, ranging from epithelial- to-mesenchymal transition to cell migration and invasion to angiogenesis...

miR-101 is significantly downregulated in various human cancers, including oral squamous cell carcinoma (OSCC). However, the role of miR-101 in OSCC has not been elucidated. In this study, miR-101 lowly expressed in OSCC tissues and cell lines compared with that in adjacent normal tissues and human normal oral keratinocyte cells. Bioinformatics analysis predicted that miR-101 could potentially target CX chemokine receptor 7 (CXCR7), a promoter of tumor development, to attenuate OSCC progression. Restoring miR-101 expression in OSCC cells suppressed cell proliferation, invasion, and migration...

Targeting cancer cell metabolism is a new promising strategy to fight cancer. Metformin, a first-line treatment for type 2 diabetes mellitus, exerts anti-cancer and anti-proliferative action. 2-deoxyglucose (2-DG), a glucose analog, works as a competitive inhibitor of glycolysis. In this study, we show for the first time that metformin in combination with 2-DG inhibited growth, migration, invasion and induced cell cycle arrest of ovarian cancer cells in vitro. Moreover, metformin and 2-DG could efficiently induce apoptosis in ovarian cancer cells, which was achieved by activating p38 MAPK and JNK pathways...
