Project description:The WWOX gene is a tumor suppressor probably involved in regulation of cell cycle and apoptosis and downregulated in variety of cancer types.However, its role in colon cancerogenesis is unknown. The aim of this study was to characterize how WWOX may be involved in colon cancerogenesis or cancer progression, how it influences the basic cancer cell features and modifies cell expression profile.Our observations suggest that in HT29 colon cancer cell line increased expression of WWOX may result in transition of cancer cells into more normal- like colon epithelium phenotype, on the other hand in SW480 WWOX revealed the well-known tumour suppressor properties. However, as the colon cancer is very heterogeneous disease, obtained discrepancies may reflect the known differences between cell lines and cancerogenesis pathway, which they undergone. HT29 colon cancer cells were stably transfected with WWOX cDNA. HT29 cells transfected with an empty vector served as a control. Total mRNA was isolated to look for gene-expression differences induced by the WWOX overexpression.

Project description:Our previous proteomics analysis suggested down-regulation of mitochondrial aconitase (ACO2) plays an important role in colorectal cancer. To evaluate the effect of mitochondrial aconitase overexpression on the metabolic and signaling pathway changes in colon cancer cell line HT29, we generated two ACO2 overexpressing cell lines #C and #UD and the mock-transfected vector control #VE. HT29 colon cancer cells overexpressing ACO2 exhibited lower rate of cell proliferation in vitro and reduced tumor growth potential in nude mice. In order to understand the signaling pathway changes, cDNA microarray analysis using GeneChips from Affymetrix were carried out.
Project description:The WWOX gene is a tumor suppressor probably involved in variety of cellular processes including and is ferquently downregulated in variety of cancer types. However, its role in endometrial cancerogenesis is not well described. The aim of this study was to characterize how WWOX may be involved in endometrial cancerogenesis, how it influences the basic cancer cell features and modifies cell expression profile.Our observations suggest that in ECC1 endometrial cancer cell line increased expression of WWOX may be involved in the initiation of EMT, leading to changes in cell adhesion and motility but also indicate its suppressive role in the process of mesenchymal phenotype acquisition, resulting in reduction of aggressiveness cell features Well differentiated ECC1 endometrial cancer cells were stably transfected with WWOX cDNA.ECC1 cells transfected with an empty vector served as a control. Total mRNA was isolated to look for gene-expression differences induced by the WWOX overexpression.
