Ago1-bound short RNAs in HeLaS3 cell line

ABSTRACT: Characterization of AGO1 bound short RNAs from nuclear extracts of HeLaS3 cell line. Nuclei were isolated from HeLaS3 cells; a fraction of Nuclear lysates was harvsted and sequenced as the input samples. The rest of nuclear lysates were immunoprecipitated using AGO1 monoclonal antibodies or Isotype matched IgG. Following immunoprecipitation, RNA was extracted from AGO1 or control IgG IP for short RNA sequencing. Two independent biological replicates were carried out.

MNASE_seq_of_AGO2_Knock_Down_HeLaS3_cells

Project description:We knocked down AGO2 protein by RNAi in HeLaS3 human cell line. The current experiment aims at comparing nucleosome positioning in control and AGO2 knock down cells. HeLaS3 cell were cultured in DMEM. Cells were transfected with AGO2 siRNAs (or control siRNA) at day 1. On day 4 MNAse digestion of chromatin was performed. Mnase-digested chromatin DNA fragments were sequenced by paired-end DNA-seq.

Ago2-bound ShortRnas in HCT116 cell line and Dicer_hypomorphic(DICER_Ex5 cells) HCT116 cell line

Project description:DICER_Ex5 cells were created by disrupting exon 5 of the human Dicer gene using an AAV targeting construct, thereby interrupting a well conserved segment of the N-terminal helicase domain while sparing the RNase III domains. In DICER_Ex5 cells, Dicer is expressed at a level lower than the wild type. This experiment started with RIP-anti-Ago2 pull-down, followed by high throughput sequencing analysis in wild type and Dicer-hypomorphic HCT116 cell lines.

SFMBT1 Functions with LSD1 to Regulate Expression of Canonical Histone Genes and Chromatin-Related Factors [ChIP-Seq]

Project description:SFMBT1 is a poorly characterized mammalian MBT domain-containing protein homologous to Drosophila SFMBT, a Polycomb group protein involved in epigenetic regulation of gene expression. Here, we show that SFMBT1 regulates transcription in somatic cells and during spermatogenesis through the formation of a stable complex with LSD1 and CoREST. When bound to its gene targets, SFMBT1 recruits its associated proteins and causes chromatin compaction and transcriptional repression. SFMBT1, LSD1, and CoREST share a large fraction of target genes including those encoding replication-dependent histones. Simultaneous occupancy of histone genes by SFMBT1, LSD1, and CoREST is regulated during the cell cycle and correlates with the loss of RNA polymerase II at these promoters during G2, M, and G1. The interplay between the repressive SFMBT1M-bM-^@M-^SLSD1M-bM-^@M-^SCoREST complex and RNA polymerase II contributes to the timely transcriptional regulation of histone genes in human cells. SFMBT1, LSD1, and CoREST also form a stable complex in germ cells and their chromatin binding activity is regulated during spermatogenesis.

Arabidopsis AGO1 N-terminal Poly-Q domain promotes phase separation and association with stress granules during heat stress

Project description:In Arabidopsis thaliana, ARGONAUTE1 (AGO1) plays a central role in microRNA (miRNA) and small interfering RNA (siRNA)-mediated silencing. Nuclear AGO1 is loaded with miRNAs and exported to the cytosol where it associates to the rough ER to conduct miRNA-mediated translational repression, mRNA cleavage and biogenesis of phased siRNAs. These latter, as well as other cytosolic siRNAs, are loaded into cytosolic AGO1, but in which compartment this happens is not known. Moreover, the effect of stress on AGO1 localization is still unclear. Here, we show that heat stress (HS) promotes AGO1 protein accumulation, which co-localize with components of the siRNA bodies and of stress granules (SGs). AGO1 does not need SGS3, a key component of siRNA bodies, to efficiently form condensates during HS. Instead, we found that the still poorly characterized N-terminal Poly-Q domain of AGO1, which contains a prion-like domain, is sufficient to undergo phase separation. Moreover, an exposure of 1 hour to HS only moderately affected AGO1 loading by miRNAs and target cleavage, suggesting that its localization in condensates protects AGO1 rather than promote its activity in reprograming gene expressing during stress. Collectively, our work shed new light on the impact of high temperature on a main effector of RNA silencing in plants.
