Effect of LINC00899 depletion on histone mark enrichment in HeLa cells
LncRNAs represent a major transcriptional output of the human genome, but the function of many of these elements is unknown. In this experiment, we have used the \"cut & run\" technique to quantify the changes in histone mark enrichment across the genome upon depletion of the lncRNA LINC00899 in HeLa cells. LINC00899 is of interest as its depletion results in mitotic delay, suggesting a role in mitotic progression. The cut & run procedure uses antibodies to target a nuclease to the relevant protein binding site, cleaving the surrounding DNA for sequencing and yielding output equivalent to that of ChIP-seq. This experiment contains 2 replicate batches where each batch contains a sample with LINC00899 knocked down by RNA interference (RNAi); a RNAi negative control; a sample with LINC00899 knocked down with locked nucleic acid antisense oligonucleotides (LNA); and a LNA negative control. This was performed using antibodies against H3K4me3, H3K27ac, H3K36me3 and H3K27me3, as well as an IgG (goat-derived anti-rabbit) control. All samples in each batch were generated at the same time. Within each batch, all cut & run experiments with the same knockdown were performed on nuclei obtained from the same cell culture. Independent cell cultures were used for experiments with different knockdown or in different batches.
