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: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:LoVo cells were cultured in sEV-depleted (160,000xg, 16h) complete medium and the supernatant were collected after 72h. sEVs were purified and centrifuged at 100,000xg for 2.5h using a Beckman SW41Ti rotor to know the miRNA in LoVo cells and LoVo-Small Extracellular Vesicles
Project description:PEAK1 overexpression vector and negative control vector were transiently transfected into LoVo cells, respectively, and named LoVo-PEAK1 and LoVo-control groups. LoVo cells of different groups were determined to investigate the different expressions of mRNA using a global gene microarray.
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.
