Project description:An RIP experiment was performed in ARP1 cell following the instructions of the article. ~5-20 × 10^6 cells were harvested and lysed. Protein A/G MagBeads pre-coated with 5μg of the antibody of interest (HNRNPA2B1/ILF3, Proteintech) and incubated with cell lysate supernatant overnight at 4°C.The beads containing immunoprecipitated RNA-protein complex were treated with 150μL of Proteinase K buffer to digest the proteins. Specific binding RNAs were isolated by using TRIzol.
Project description:RNA pulldown assay showed that lncRNA UBE2CP3 could bind to ILF3 protein. In order to further verify the interaction between ILF3 and UBE2CP3, RNA Immunoprecipitation (RIP) assay was performed to identify the RNAs that binds to ILF3 protein. RIP-seq data verifies the interaction between ILF3 and UBE2CP3. Interestingly, UBE2CP3 could also binds to 3'UTR of IGFBP7 mRNA. Mechanismly, lncRNA UBE2CP3 and 3' UTR of IGFBP7 could forms an double-stranded RNA. Then, the RNA duplex could interact with the Double-Stranded RNA-Binding Protein ILF3.
Project description:To study the impact of ILF3 in the context of cancer, we established the AOM/DSS colitis-associated CRC model. We then performed gene expression profiling analysis using data obtained from RNA-seq of 3 different tumor tissues from Ilf3-WT and Ilf3-KO mice
