G4 single-cell CUT&Tag (G4 scCUT&Tag) profiles distinct G-quadruplex landscapes across postnatal mouse brain cell lineages, linking promoter G4 heterogeneity to lineage-specific gene subsets.
- Why it matters: G-quadruplex structures are implicated in gene regulation and disease, yet their systematic, cell-type-resolved patterns across tissues remain unclear.
- What they did: The study applies G4 scCUT&Tag to postnatal mouse brain cells and uses single-cell omics workflows plus multi-omics integration with scRNA-Seq, including canonical correlation analysis and a transfer learning approach.
- The result: Integration reveals correlations between G4 signal and gene expression and enables more accurate cell-type annotation, supporting detailed analysis of G4 heterogeneity and its relationship to other chromatin layers in developing brain.
