Summary

The long noncoding RNA Malat1 impacts the differentiation of effector and memory CD8+ T cell subsets by virtue of preferential epigenetic repression of memory-associated genes in terminal effector cells through an interaction with Ezh2

Overall Design

Malat1 Knockdown and Nontarget P14 CD8+ T cells were sorted 7 days after LCMV infection

Processing steps for GSE203086
  1. Reads from scRNA-seq were aligned to mm10 using the 10x Genomics Cell Ranger software (v 2.1.0).
  2. Reads were collapsed into unique molecular identifier counts.
  3. All samples had >2000 cells detected with >1000 genes per cells with >70% of the coding genome covered.
  4. Genes that were not expressed in at least 5% of all cells were excluded.
  5. As previously described (Boland et al., 2020), replicates of single cell libraries were normalized removing batch effects using RUVnormalize (v1.15.0).
  6. The raw UMI matrix was scaled and input to the naiveRandRUV function with parameters coeff=1e-3 and k=10.
  7. Fifty negative control genes were taken from a list of housekeeping genes (Eisenberg and Levanon, 2013) with least variability in all datasets.
  8. Seurat (v3.0.1) functions were used to calculate top variable genes, principal components analysis (PCA), and tSNE with FindVariableGenes, RunPCA, and RunTSNE.
Showing first 8 steps.
