Epigenetic regulators are constituted by a great diversity of subunits, which are often redundant to varying extents. Novel experimental strategies including genome editing and small molecule-inducible systems allow for systematic dissection of multi-subunit complexes. While these approaches are ideal to assess the transcriptional consequences of combinatorial genetic perturbations to epigenetic pathways, the sequencing costs associated with gene expression analysis by RNA-seq quickly escalate as a function of sample number.
Lexogen QuantSeq facilitates increased multiplexing capacity without ramping up the sequencing costs by focusing on the 3’ ends of mRNAs. Such gene expression profiling approaches require only about 10 percent of sequencing depth compared to standard RNA-seq methods.
In this webinar, Jorge Zepeda from Lexogen will discuss a study conducted at the Institute of Molecular Biotechnology that used small molecule-inducible genetic perturbations in combination with transcriptional profiling by QuantSeq and chromatin immunoprecipitation sequencing (ChIP-seq) analysis to unravel the differential subunit requirements of polycomb repressive complexes 1 (PRC1) and 2 (PRC2), in maintaining robust silencing of lineage-specific genes and self-renewal capacity in mouse embryonic stem cells.
The second speaker, Jean Lozach from OnRamp Bio will demonstrate the capabilities of the OnRamp Bioinformatics discovery platform Rosalind to analyze and integrate multi-omics datasets like the QuantSeq and ChIP-seq used in this study and, will also show a new option for efficient collaboration between researchers.
