Comparison of bulk RNAseq results of WT and TKO E14 NPCs

Project description:We investigate the impact of DNA methylation on neural somatic differentiation. To this end, we used in vitro neural progenitor cell (NPC) differentiation on WT and DNA-methylation free TKO murine ESCs. We next performed bulk RNAseq at D0, D2, D4, D6 and D8 of differentiation to study transcriptomic differences.

Single cell SMART RNAseq on WT and TKO E14 EpiLCs

Project description:We investigate how DNA methylation absence impact transcriptionnal regulation during epiblast differentiation. More specifically, how synchronous is the naïve to primed transitioning in TKO cells compared to WT, and if there is a "germline-competent" TKO subpopulation of EpiLCs. To this end, we used in vitro Epiblast-like cell (EpiLC) differentiation WT and TKO at D0, D1, D2 and D4. We next performed single-cell SMARTseq2 RNA sequencing.

A web-based search tool for visualizing instrument performance using the Triple Knockout (TKO) proteome standard

Project description:Multiplexing strategies are at the forefront of mass spectrometry-based proteomics, with SPS-MS3 methods becoming increasingly commonplace. A known caveat of isobaric multiplexing is interference resulting from co-isolated and co-fragmented ions that do not originate from the selected precursor of interest. The triple knockout (TKO) standard was designed to benchmark data collection strategies to minimize interference. However, a limitation to its widespread use has been the lack of an automated analysis platform. Here, we present a TKO Visualization Tool (TVT). The TVT viewer allows for automated, web-based, database searching of the TKO standard, returning traditional figures of merit, such as peptide and protein counts, scan-specific ion accumulation times, as well as the TKO-specific metric, the IFI (interference-free index). Moreover, the TVT viewer allows for plotting of multiple TKO standards to assess protocol optimizations, compare instruments, or measure degradation of instrument performance over time. To showcase the TVT viewer, we investigated the selection of 1) stationary phase resin, 2) MS2 isolation window width, and 3) number of SPS ions for SPS-MS3 analysis. Using the TVT viewer will allow the proteomics community to search and compare TKO results to optimize user-specific data collection workflows.

Transcription profiling of mouse Rb family triple knock-out (TKO) embryonic stem cells as they differentiate in vivo

Project description:The retinoblastoma cell cycle regulator pRb and the two related proteins p107 and p130 are thought to suppress cancer development both by inhibiting the G1/S transition of the cell cycle in response to growth-arrest signals and by promoting cellular differentiation. Here, we investigated the phenotype of Rb family triple knock-out (TKO) embryonic stem cells as they differentiate in vivo and in culture. Confirming the central role of the Rb gene family in cell cycle progression, TKO mouse embryos did not survive past mid-gestation and differentiating TKO cells displayed increased proliferation and cell death. However, patterning and cell fate determination were largely unaffected in these TKO embryos. Furthermore, a number of TKO cells, including in the neural lineage, were able to exit the cell cycle in G1 and terminally differentiate. This ability of Rb family TKO cells to undergo cell cycle arrest was associated with the repression of target genes for the E2F6 transcription factor, uncovering a pRb-independent control of the G1/S transition of the cell cycle. These results show that the Rb gene family is required for proper embryonic development but is not absolutely essential to induce G1 arrest and differentiation in certain lineages. Experiment Overall Design: Genome-wide gene expression was analyzed for wild-type and TKO ESC and EB cells. Three biological replicates were isolated for wild-type ESCs, TKO ESCs, and wild-type EBs, while five biological replicates were isolated for TKO EBs.
