Diverse effect of WWOX overexpression in SW480 colon cancer cell line.

ABSTRACT: 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. SW480 colon cancer cells were stably transfected with WWOX cDNA. SW480 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.

The influence of WWOX tumor supressor gene on endometrial cancerogenesis

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.

Gene expression profiling of WWOX-overexpressing glioblastoma T98G cells

Project description:The WWOX gene is known for its tumor suppressor character and seems to be one of the main cellular regulators of cell cycle and apoptosis. The aim of the study was to identify cellular pathways and biological processes influenced by WWOX in glioblastoma cells. Our experiment showed that in this type of cancer WWOX, beside cell cycle and apoptosis control, may be involved in metabolism, cytoskeleton structure and differentiation. T98G glioblastoma cells were stably transfected with WWOX cDNA. T98G 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.

MicroRNA expression profile between human colorectal cancer SW480 and SW620 cell line

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.

Transcription profiling of effected genes by compound BIO,3G4 and knockdown of MED23

Project description:Drug discovery, inhibition of WNT pathway and identification of molecular targets. Prostate EPT1cells were treated with 6-bromoindirubin-3ΓÇÖ-oxime(BIO) or DMSO for 24 hours, colon cancer SW480 cells were treated with compound 3G4 for 24 and 72 hours, SW480 cells were transfected with MED23 knockdown shRNA vector for 48 hours. Cells were harvested and total RNA was extracted using Qiazol method followed by Agilent DNA microarray analysis.

Transcription profiling of effected genes by PAD2 and compound 1B8

Project description:To understand the growth inhibition of peptidylarginine deiminase 2 (PAD2) and small molecule 1B8, colon cancer SW480 cells were treated with compound 1B8 for 24 hours, SW480 cells were transfected with humanPAD2 vector for 24 hours. Cells were harvested and total RNA was extracted using TRIZol method followed by Agilent DNA microarray analysis. To profile the effected genes by compound 1B8, SW480 cells were treated with DMSO (control) and 10uM 1B8 in triplicates in 6-well plate, cells were harvested 24 hours later. To compare the effected genes by compound 1B8 and PAD2 overexpression, SW480 cells were transfected with PAD2 and pIRES2-EGFP empty vector in triplicates in 6 well plates, cells were harvested in 24 hours. All the cells were harvested and total RNA was extracted using TRIZol method followed by Agilent DNA microarray analysis.

MicroRNA profiling of human colon cancer cell lines from the primary lesion and lymph node metastatis of the same patient

Project description:Two colon cancer cell lines, SW480 and SW620, were originated from the same patient. The SW480 cell line was derived from a primary lesion, and the SW620 cell line was cultured from a lymph node metastasis with no intervening chemotherapy at a later time. Since these two cell lines are from a single person, it is likely that differences between the two cell lines represent the changes when cancer cells acquire metastatic potential. Thus, this system represents a perfect model for the study of metastatic mechanism. To investigate cancer metastasis associated miRNAs, we detected the miRNA profiles in these two cell lines.
