Fig. 1: HMGA1 is highly expressed in esophageal cancer.

A–C The tSNE map showed the distribution of epithelial cells from normal (N) and tumor (T) in esophageal tissue in ESCC patients from scRNA-seq data in the GEO database (GSE188900 dataset). HMGA1 was mainly expressed in epithelial cells from tumor (C). D HMGA1 expression in ESCC (n = 28) and paired paracancerous (n = 10) samples in the GEO database (GSE45670 dataset). E The TCGA database analyzes the expression of HMGA1 at normal and tumor tissues of different stages of ESCCs. F, G Representative IHC staining of HMGA1 in paired ESCC tissues. Scale bars: 50 μm. H, I Representative IHC staining of HMGA1 in 4NQO-induced esophageal tumor tissue and H2O-treated normal esophageal tissue. Scale bars: 50 μm.
