Project description:This SuperSeries is composed of the following subset Series: GSE26334: Expression data from LoVo colon cancer lines +/- constitutive LIN28B expression GSE26335: Expression data from xenograft tumors derived from LoVo colon cancer lines +/- constitutive LIN28B expression Refer to individual Series
Project description:We sought to elucidate the molecular mechanisms whereby LIN28B functions by comparing the gene expression profile of cells constitutively expressing LIN28B to empty vector controls. Accordingly, we performed microarray analysis on total RNA isolated from empty vector LoVo and LIN28B-expressing LoVo colon cancer cell lines. Constitutive LIN28B expression was achieved in the LoVo (ATCC #CCL-229) colon cancer cell line via retroviral transduction of MSCV-PIG-LIN28B. Contol = empty vector MSCV-PIG.

Project description:We sought to elucidate functions of LIN28B and potential mechanisms whereby it may promote metastasis by comparing the gene expression profile of LIN28B metastases to primary tumors. Accordingly, we performed microarray analysis on total RNA isolated from empty vector tumors, LIN28B-LoVo tumors, and LIN28B-LoVo metastases Constitutive LIN28B expression was achieved in the LoVo (ATCC #CCL-229) colon cancer cell line via retroviral transduction of MSCV-PIG-LIN28B. xenografts were produced via injection of 1x106 cells subcutaneously into the rear flanks of nude mice. Microarrays were conducted on primary tumors from empty vector and LIN28B-expressing cells, as well as metastases derived from primary tumors constitutively expressing LIN28B. (Note: metastases did not occur with empty vector tumors)

Project description:To investigate the expression patterns driven by hyperactivated MET in MET-dependent cells, we employed LoVo colon adenocarcinoma cell line, harbouring a post-translational modification of MET that leads to its constitutive activation. We then silenced MET in LoVo cells using CRISPR/Cas9 knock-out (KO) protocol, and performed gene expression profiling analysis using data obtained from RNA-seq of cells with hyperactivated-MET versus MET-KO.
Project description:Six non- and drug-resistant colorectal cancer cell lines were selected in this study, which were non-resistant cell lines: HCT116 and LoVo, four drug-resistant cell lines: HCT116-OxPt, HCT116-SN38, LoVo-OxPt, LoVo-SN38.Proteins extraced from three HCT116 related cell lines were labled and pooled together, and proteins from other three LoVo related cell lines were labled and pooled together.
