Validation in single-cell RNA-Seq dataset. A. Identification of varied cell types in the single-cell RNA-Seq dataset by using UMAP algorithm. B. Proportions of different cell types in AD and normal control samples. C. The violin diagram shows the differences in the expression of RPS27A, RPL24, RPL5 and RPS4X in AD and normal samples (Wilcoxon t-test, *P < 0.05, **P < 0.01). D. The expression profile of RPS27A, RPL24, RPL5 and RPS4X in different types of cells in scRNA-Seq dataset. Abbreviation: AD: Alzheimer’s disease; NC: normal control.
