Colon cancer is the most common type of gastrointestinal cancer. Despite advances during the last two decades, the efficacy of colorectal cancer treatment is still insufficient and new anticancer agents are necessary. In our study, colon cancer cells derived from a primary tumor (SW480) and lymph node metastasis (SW620) from the same patient were used and compared. The effect of FLU on cell adhesion and migration was monitored using the x-CELLigence Real-Time Cell Analysis system. Expressions of molecules involved in adhesion and migration were analyzed using RT-PCR and western blot...

Background: Upon initial presentation, 25%-30% of patients with renal cell carcinoma have metastatic disease. Metastasis to the gastrointestinal tract is rare, but when it occurs, the large bowel is the least common site. Case Report: A 75-year-old white male presented with vague abdominal symptoms and worsening hemoglobin and hematocrit levels. Colonoscopy revealed a polyp in the distal portion of the sigmoid colon. Histologic and immunohistochemical analysis suggested metastatic papillary renal cell carcinoma...

MORC family CW-type zinc finger 2 (MORC2) is a newly identified chromatin remodeling protein with emerging roles in the regulation of DNA damage response and gene transcription, but its mechanistic role in breast cancer development and progression remains unexplored. Here, we show that MORC2 promoted breast cancer invasion and metastasis and these effects depended on a proline-rich domain (PRD) within its carboxy-terminal region spanning residues 601-734. Induced expression of wild-type MORC2 did not significantly affect cell proliferation and cell-cycle progression, but promoted breast cancer cell migration and invasion in vitro and metastatic lung colonization in vivo...

For a patient with metastatic colorectal cancer there are limited clinical options aside from chemotherapy. Unfortunately, the development of new chemotherapeutics is a long and costly process. New methods are needed to identify promising drug candidates earlier in the drug development process. Most chemotherapies are administered to patients in combinations. Here, an in vitro platform is used to assess the penetration and metabolism of combination chemotherapies in three-dimensional colon cancer cell cultures, or spheroids...

Exposure to ambient particulate matter (PM) has been linked to the increasing incidence and mortality of lung cancer, but the principal toxic components and molecular mechanism remain to be further elucidated. In this study, human lung adenocarcinoma A549 cells were treated with serial concentrations of water-extracted PM10 (WE-PM10) collected from Beijing, China. Our results showed that exposure to 25 and 50 μg/ml of WE-PM10 for 48 h significantly suppressed miR-26a to upregulate lin-28 homolog B (LIN28B), and in turn activated interleukin 6 (IL6) and signal transducer and activator of transcription 3 (STAT3) in A549 cells, subsequently contributing to enhanced epithelial-mesenchymal transition and accelerated migration and invasion...

BACKGROUND: Recent evidence from clinical trials suggests that primary tumor location in patients with metastatic colorectal cancer correlates with differential outcomes, and patients with tumors originating in the right side of the colon have inferior survival. We conducted a large population-based cohort study using individual patient data to confirm the prognostic importance of primary tumor location in the general population with metastatic colorectal cancer. METHODS: A cohort of 1947 patients who were diagnosed with metastatic colorectal cancer from 1992 to 2010 was studied...

As one of crucial epigenetic modification, DNA methylation plays an important role during the carcinogenesis of colorectal cancer (CRC). In the current study, we used a human genome methylation array to detect the aberrant methylation genes in CRC. We further identified the hypermethylation of claudin-11 (CLDN11) and proved inverse correlation between CLDN11 methylation and its expression in CRC. In vitro experiments showed debased migration ability of colonic cancer cells in accompany with the converted methylation of CLDN11 after colonic cancer cells treated with demethylation agent, 5-aza-2'-deoxycytidine...

AIMS: Hepatic progenitor cells (HPCs) are activated in various liver diseases but their role in carcinomatous environment remains unknown. We aimed to identify the possible presence and topography of HPCs in liver metastases. METHODS: We examined 14 liver resection specimens for colorectal adenocarcinoma (CRC) (n=13) and anal squamous cell carcinoma (SCC) (n=1) metastases. Immunohistochemical markers of colonic (keratin 20-K20, CDX2) and squamous cell origin (p63), HPC (K19, CD56) and stem cell (CD44) markers, and the biliary marker K7 which may also highlight HPCs were applied on routinely processed tissue sections...

Cancer metastasis occurs through a series of sequential steps, which involves dissemination of tumor cells from a primary site and colonization in distant tissues. To promote the invasion-metastasis cascade, carcinoma cells usually initiate a cell-biological program called epithelial-mesenchymal transition (EMT), which is orchestrated by a set of master regulators, including TGF-β, Snail, ZEB and Twist families. The biological activities of these molecules are tightly regulated by a variety of cell-intrinsic pathways as well as extracellular cues...

PURPOSE: Vitamin D exerts its inhibitory influence on colon cancer growth by inhibiting Wnt signaling and angiogenesis. We hypothesized that SNPs in genes involved in vitamin D transport, metabolism and signaling are associated with outcome in metastatic colorectal cancer (mCRC) patients treated with first-line FOLFIRI and bevacizumab (bev). EXPERIMENTAL DESIGN: 522 mCRC patients enrolled in the FIRE-3 (discovery cohort) and TRIBE (validation set) trials treated with FOLFIRI/bev were included in this study...

BACKGROUND: Lymphocyte Function-Associated Antigen-1 (LFA-1; CD18/CD11a) is one of the main adhesion molecules used by immune cells to infiltrate the liver under inflammatory conditions. Recently, the expression of this integrin has also been reported on several solid tumors, including colorectal cancer. However, its functional role in the metastatic progression to the liver remains unknown. Using in vitro assays and an experimental orthotopic in vivo model of liver metastasis, we aimed to elucidate the role of tumor LFA-1 in the metastatic progression by means of the partial depletion of the β2 subunit of LFA-1, required for integrin activation, firm adhesion and signaling...

BACKGROUND: Reduced RHOA signalling has been shown to increase the growth/metastatic potential of colorectal tumours. However, the mechanisms of inactivation of RHOA signalling in colon cancer have not been characterised. METHODS: A panel of colorectal cancer cell lines and large cohorts of primary tumours were used to investigate the expression and activity of RHOA, as well as the presence of RHOA mutations/deletions and promoter methylation affecting RHOA. Changes in RHOA expression were assessed by western blotting and qPCR after modulation of microRNAs, SMAD4 and c-MYC...

Purpose: Conjunctival melanoma (CM) is a rare malignant disease that can lead to recurrences and metastases. There is a lack of effective treatments for the metastases, and we set out to develop a new animal model to test potential therapies. Zebrafish are being used as a model for many diseases, and our goal was to test whether this animal could be used to study CM. Methods: Three human CM cell lines (CRMM-1 and CM2005.1, which both harbor a B-RAF mutation, and CRMM-2, which has an N-RAS mutation) were injected into the yolk sac, around the eye, and into the duct of Cuvier of transgenic (fli:GFP) Casper zebrafish embryos...

Ovarian cancer is one of the most common gynecological cancers worldwide. It is the third leading cause of cancer among women in India. Metastatic disease to the visceral organs from ovarian cancer occurs as a terminal event in the natural history of the disease. In particular, spread to the bone and large bowel is infrequently described. The risk of distant metastasis increases in a recurrent setting. We describe a case of a 77-year-old lady, who was diagnosed for ovarian carcinoma in 2007 and underwent primary cytoreductive surgery, stage IIIc...

PURPOSE:   Recent studies have highlighted the existence of sub-clones in tumors. Lymph nodes are generally the first location of metastasis for most solid epithelial tumors including colorectal cancer (CRC). We sought to understand the genetic origin of lymph node metastasis in CRC by evaluating the relationship between CRC tumor sub-clones present in primary tumors and lymph nodes. EXPERIMENTAL DESIGN:   A total of 33 samples from seven CRC's, including two or three spatially disparate regions from each primary tumor and one to four matched lymph nodes for each tumor, underwent next-generation whole-exome DNA sequencing, Affymetrix OncoScan SNP arrays, and targeted deep confirmatory sequencing...
