To identify novel biomarkers of metastasis of colorectal cancer (CRC), we developed an orthotopic implantation model of murine CRC and selected in vivo M5, a subclone of the SW480 CRC cell line with enhanced potential for metastasis to the liver. We compared the differences in the gene expression profiles between M5 and SW480 cells using gene expression(More)
BACKGROUND LIM and SH3 protein 1 (LASP-1), initially identified from a cDNA library of metastatic axillary lymph nodes of breast cancer patients, is a specific focal adhesion protein involved in numerous biological and pathological processes. The overexpression of LASP-1 has been described in several types of cancers, but the role of LASP-1 in colorectal(More)
The dengue virus (DENV) has four distinct serotypes (DENV1, DENV2, DENV3, and DENV4) that require differentiation for effective prevention of morbid diseases. The recently developed DENV1-specific NS1 antigen capture enzyme-linked immunosorbent assay (ELISA) based on the monoclonal antibodies (MAbs) that recognize distinct epitopes on nonstructural protein(More)
BACKGROUND & AIMS Formin-like (FMNL)2 is up-regulated in colorectal tumors and has been associated with tumor progression, but little is known about regulatory mechanisms. We investigated whether microRNAs regulate levels of FMNL2 in colorectal cancer (CRC) cells. METHODS We used real-time polymerase chain reaction and immunoblot analyses to measure(More)
To understand the molecular mechanisms of metastasis and prognosis of colorectal cancer (CRC), we isolated single cell-derived progenies (SCPs) from SW480 cells in vitro and compared their metastatic potential in an orthotopic CRC tumour model in vivo. Two groups of SCPs with the capability of high and low metastasis, respectively, were obtained. By(More)
BACKGROUND We have demonstrated that T lymphoma invasion and metastasis 1 (Tiam1) gene is associated with the poor prognosis of patients with hepatocellular carcinoma (HCC), and we used a computational approach to identify miR-141 as a Tiam1-targeting microRNA (miRNA). Here, we explored the function of miR-141 and the relationship between miR-141 and Tiam1(More)
In order to investigate the clinical pathology of severe acute respiratory syndrome (SARS), the autopsies of three patients who died from SARS in Nan Fang Hospital Guangdong, China were studied retrospectively. Routine haematoxylin and eosin (H&E) staining was used to study all of the tissues from the three cases. The lung tissue specimens were studied(More)
PURPOSE This study was to investigate the clinicopathologic significance and potential role of HOXB7 in the development and progression of colorectal cancer (CRC). EXPERIMENTAL DESIGN The relationship between HOXB7 expression and clinical characteristics of CRC was analyzed in 224 paraffin-embedded archived CRC specimens by immunohistochemistry (IHC). The(More)
Formin-like 2 (FMNL2) is a member of diaphanous-related formins which can control the actin-dependent processes such as cell motility and invasion. In this study, we investigated the expression of FMNL2 in colorectal cancer (CRC) and its correlation with CRC metastasis. Paraffin-embedded specimens of CRC (including 75 primary CRC tumors and 45 corresponding(More)
Colorectal cancer (CRC) is the third most common cancer in the USA. MicroRNAs play important roles in the pathogenesis of CRC. In this study, we investigated the role of miR-30b in CRC and found that its expression was significantly lower in CRC tissues than that in normal tissues. We showed that a low expression level of miR-30b was closely related to poor(More)
