RISC-mediated control of selected chromatin regulators stabilizes ground state pluripotency of mouse embryonic stem cells (RNAi)

ABSTRACT: We performed an integrated analysis of RNA and proteins at the transition between naÃ¯ve ES cells and cells primed to differentiate. During this transition, mRNAs coding for chromatin regulators were specifically released from translational inhibition mediated by RNA-Induced Silencing Complex (RISC). This suggests that, prior to differentiation, the propensity of ES cells to change their epigenetic status is hampered by RNA interference. The expression of these chromatin regulators was reinstated following acute inactivation of RISC, and it correlated with loss of stemness markers and activation of early cell differentiation markers in treated ES cells. We assayed the impact of the functional inhibition of chromatin regulators on cell priming inhibiting chromatin remodeling activities by either pharmacological or genetic interference.

RISC-mediated control of selected chromatin regulators stabilizes ground state pluripotency of mouse embryonic stem cells (miRNA-Seq)

Project description:We performed an integrated analysis of RNA and proteins at the transition between naÃ¯ve ES cells and cells primed to differentiate. During this transition, mRNAs coding for chromatin regulators were specifically released from translational inhibition mediated by RNA-Induced Silencing Complex (RISC). This suggests that, prior to differentiation, the propensity of ES cells to change their epigenetic status is hampered by RNA interference. The expression of these chromatin regulators was reinstated following acute inactivation of RISC, and it correlated with loss of stemness markers and activation of early cell differentiation markers in treated ES cells. We evaluated global miRNA profiles of embryonic stem cells cultured in either 10%FCS+LIF or 2i+LIF and of Epiblast-Like Aggregates derived from ES cells in 10%FCS+LIF or 2iL+LIF.

KDM5B focuses H3K4 methylation near promoters and enhancers during embryonic stem cell self-renewal and differentiation [ChIP-Seq]

Project description:Pluripotency of embryonic stem (ES) cells is controlled in part by chromatin-modifying factors that regulate histone H3 lysine 4 (H3K4) methylation. However, it remains unclear how H3K4 demethylation contributes to ES cell function. Here, we show that KDM5B, which demethylates lysine 4 of histone H3, co-localizes with H3K4me3 near promoters and enhancers of active genes in ES cells; its depletion leads to spreading of H3K4 methylation into gene bodies and enhancer shores, indicating that KDM5B functions to focus H3K4 methylation at promoters and enhancers. Spreading of H3K4 methylation to gene bodies and enhancer shores is linked to defects in gene expression programs and enhancer activity, respectively, during self-renewal and differentiation of KDM5B-depleted ES cells. KDM5B critically regulates H3K4 methylation at bivalent genes during differentiation in the absence of LIF or Oct4. We also show that KDM5B and LSD1, another H3K4 demethylase, co-regulate H3K4 methylation at active promoters but they retain distinct roles in demethylating gene body regions and bivalent genes. Our results provide global and functional insight into the role of KDM5B in regulating H3K4 methylation marks near promoters, gene bodies, and enhancers in ES cells and during differentiation. ChIP-Seq for KDM5B, H3K4 methylation and H3K27ac in murine shLuc, shKdm5b, shLuc-LSD1i, shKdm5b-LSD1i ES cells, and during differentiation of shLuc and shKdm5b ES cells for 2 days, 3 days, and 4 days without LIF.

Extended self-renewal and accelerated reprogramming in the absence of Kdm5b [RNA-Seq]

Project description:ES cell pluripotency is thought to be regulated in part by H3K4 methylation. However, it is unclear how H3K4 demethylation contributes to ES cell function and participates in iPS cell reprogramming. Here, we show that KDM5B, which demethylates H3K4, is important for ES cell differentiation, and presents a barrier to the reprogramming process. Depletion of Kdm5b leads to an extension in the self-renewal of ES cells in the absence of LIF. Transcriptome analysis revealed the persistent expression of pluripotency-genes and underexpression of developmental genes during differentiation in the absence of Kdm5b, suggesting that KDM5B plays a key role in cellular fate changes. We also observed accelerated reprogramming of differentiated cells in the absence of Kdm5b, demonstrating that KDM5B is a barrier to the reprogramming process. Expression analysis revealed that mesenchymal master regulators associated with epithelial-to-mesenchymal transition (EMT) are downregulated during reprogramming in the absence of Kdm5b. Moreover, global analysis of H3K4me3/2 revealed that enhancers of fibroblast genes are rapidly deactivated in the absence of Kdm5b, and genes associated with EMT lose H3K4me3/2 during the early reprogramming process. These findings provide functional insight into the role for KDM5B in regulating ES cell differentiation and as a barrier to the reprogramming process.

RISC-mediated control of selected chromatin regulators stabilizes ground state pluripotency of mouse embryonic stem cells (RNA)

Project description:We performed an integrated analysis of RNA and proteins at the transition between naïve ES cells and cells primed to differentiate. During this transition, mRNAs coding for chromatin regulators were specifically released from translational inhibition mediated by RNA-Induced Silencing Complex (RISC). This suggests that, prior to differentiation, the propensity of ES cells to change their epigenetic status is hampered by RNA interference.
