Expression levels and correlation analysis of FRGs among immune cells in the single-cell dataset GSE149614. A Heat map of the expression of 20 FRGs among immune cells. The top annotation bar indicates five immune cell types: T cells, macrophages, dendritic cells, B cells, and monocytes. Light-to-dark color gradient represents the progressively elevated expression level, with red color suggesting a positive relationship and blue color suggesting a negative relationship. B Heat map of the correlation of 20 FRGs, where red color denotes a positive relationship and blue color denotes a negative relationship. C–I tSNE plots showing the expression levels of ZFP36 (C), NCOA4 (D), FTH1 (E), FTL (F), TNF (G), PCBP1 (H), and CYB561A3 (I) in the single cell data set
