Project description:Two isogenic human colorectal cancer cell lines (primary SW480 cell line and its lymph node metastatic variant SW620 cell line),as an in vitro metastatic model. We have demonstrated that SW620 cell line possesses high metastasis potential and SW480 cell linepossesses low metastatic potential. We want to compare the whole cell microRNAs profiles of two isogenic colorectal cancer cell lines (SW480 and SW620 cell line), to gain an insight into the molecular events of colon cancer metastasis.

Project description:To investigate the role of TGF-M-NM-21-regulated miRNAs in the progression of colorectal cancer,we performed comprehensive miRMA microarray analysis on RNA derived from typical human colorectal cancer cell lines and TGF-M-NM-21 knock-down human colorectal cancer cell lines. We identified a novel set of TGF-M-NM-21-related miRNAs. Total RNA was isolated from TGF-M-NM-21-knock down colorecatl cancer cell lines and controls.Three-condition experiment: shRNA-TGF-M-NM-21/Lovo cells vs. shRNA-Control/Lovo cells, shRNA-TGF-M-NM-21/SW620 cells vs. shRNA-Control/ SW620 cells, and shRNA-TGF-M-NM-21/HT29 cells vs. shRNA-Control/HT29 cells. Biological replicates: 1 Lovo cells stably transfected with shRNA-TGF-M-NM-21- pSUPER gfp-neo, 1SW620 cells stably transfected with shRNA-TGF-M-NM-21- pSUPER gfp-neo, 1HT29 cells stably transfected with shRNA-TGF-M-NM-21- pSUPER gfp-neo, 1Love cells stably transfected with shRNA-Control- pSUPER gfp-neo, 1SW620 cells stably transfected with shRNA-Control- pSUPER gfp-neo, and 1HT29 cells stably transfected with shRNA-Control- pSUPER gfp-neo, independently grown and harvested. One replicate per array.

Project description:Dissemination of primary tumors to distant anatomical sites has a substantial negative impact on patient prognosis. The liver is a common site for metastases from colorectal cancer, and patients with hepatic metastases have generally much shorter survival, raising a need to develop and implement novel strategies for targeting metastatic disease. The extracellular matrix (ECM) is a meshwork of highly crosslinked, insoluble, high molecular weight proteins maintaining tissue integrity and establishing cell-cell interactions. Emerging evidence identifies the importance of the ECM in cancer cell migration, invasion, intravasation, and metastasis. Here, we isolated the extracellular matrix from MC38 mouse liver metastases using our optimized method of mild detergent solubilization followed by biochemical enrichment. The matrices were subjected to label-free quantitative mass spectrometry analysis, revealing proteins highly abundant in the metastatic matrisome. The resulting list of differentially expressed proteins significantly predicted survival in patients with colorectal cancer but not other cancers with strong involvement of the extracellular matrix component. One of the proteins upregulated in liver metastatic ECM, Annexin A1, was not previously studied in the context of cancer-associated matrisome. Here we show that Annexin A1 was markedly upregulated in colon cancer cell lines compared to cancer cells of other origin, and also overrepresented in human primary colorectal lesions as well as hepatic metastases in comparison with their adjacent healthy tissue counterparts. In conclusion, our study provides a comprehensive ECM characterization of MC38 experimental liver metastases and proposes Annexin A1 as a putative target for this disease.

Project description:Metastasis is the major cause of cancer-related death in patients with colorectal cancer. Although inducible nitric oxide synthase (iNOS) is a crucial regulator of cancer development and progression, its roles in epithelial-mesenchymal transition (EMT) and the pathogenesis of metastatic colorectal cancer have not been fully investigated. Primary colorectal cancer and liver metastatic tissue specimens were analyzed showing 90% of liver metastatic colorectal cancer with reduced expressions of iNOS compared with 6% of primary colorectal cancer. The Cancer Genome Atlas database analyses via cBioPortal reveal that mRNA expression of iNOS negatively correlated with selected EMT markers in colorectal cancer in a cancer type-dependent manner. The transcriptomic profiling (RNA sequencing data) indicates that iNOS knockdown in SW480 colorectal cancer cells induced an EMT program with upregulated expression of selected stem-cell markers. iNOS knockdown did not alter E-cadherin mRNA expression but re-localized it from membrane to cytoplasm through iNOS-GATA4-Crb2-E-cadherin pathway. iNOS knockdown induced a change in cell morphology, and promoted cell invasion and migration in vitro, and metastasis in vivo.

Project description:Metastasis is a complex process involving multiple steps. We were interested in the role of microRNAs (miRNAs) in the process of liver colonization by colorectal cancer cells. We hypothesized that the comparison between non-metastatic versus metastatic isogenic cell line should thus offer valuable insight to the molecular mechanisms involved in developing metastatic behavior. KM12C/KM12SM and SW480/SW620 are probably the best available models of isogenic cell lines differing in metastatic properties for colorectal cancer. Our first goal was to identify miRNAs that contribute to the metastatic traits of the isogenic colorectal cancer cell lines, KM12C/KM12SM and SW480/SW620. Total RNA was extracted from cells using the mirVana kit (Ambion). Total RNA (1 µg) from KM12C and SW480 (poorly metastatic) and KM12SM and SW620 (highly metastatic) cells was used to analyze the global miRNA expression profiling with TaqMan Megaplex human array A (v2.0) and B (v3.0) (Applied Biosystems).

Project description:Despite advances in contemporary chemotherapeutic strategies, long term survival still remains elusive for patients with metastatic colorectal cancer. A better understanding of the molecular markers of drug sensitivity to match therapy with patient is needed to improve clinical outcomes. In this study, we used in vitro drug sensitivity data from the NCI-60 cell lines together with their Affymetrix microarray data to develop a gene expression signature to predict sensitivity to oxaliplatin. In order to validate our oxaliplatin sensitivity signature, Patient-Derived Colorectal Cancer Explants (PDCCEs) were developed in NOD-SCID mice from resected human colorectal tumors. Analysis of gene expression profiles found similarities between the PDCCEs and their parental human tumors, suggesting their utility to study drug sensitivity in vivo. The oxaliplatin sensitivity signature was then validated in vivo with response data from 14 PDCCEs treated with oxaliplatin and was found to have an accuracy of 92.9% (Sensitivity=87.5%; Specificity=100%). Our findings suggest that PDCCEs can be a novel source to study drug sensitivity in colorectal cancer. Furthermore, genomic-based analysis has the potential to be incorporated into future strategies to optimize individual therapy for patients with metastatic colorectal cancer. Fourty-two human tumors and murine explants of colorectal origin, both primary colon and of various metastatic sites, were processed for total RNA. The samples included RNA from 14 patient samples in addition to RNA from Patient-Derived Colorectal Cancer Explant (PDCCEs) generated from these 14 patient samples. The PDCCEs were processed as fresh frozen whole tumor in addition to formalin-fixed paraffin-embedded (FFPE) tumors.
