PTPN1 and colorectal cancer: Subsequently,we characterized PTPN1 expression within the tumorimmune microenvironment through bioinformatic analysis of a largesingle-cell RNA-sequencing cohort of colorectal cancer (GSE132465;63,689 cells from 23 tumors and 10 normal mucosa samples) (Figure C and Supplementary Figure 38). This analysis revealed distinct, cell type-specific expressionpatterns.
