Popis: The liver is structurally organized into zonation, where Liver Sinusoidal Endothelial Cells (LSECs) play a crucial role during chronic liver injury and the early stages of fibrosis. Fibrosis can be reversed if diagnosed early at the molecular level in zonation before progressing to advanced stages like bridging fibrosis. This study identified zonation marker genes using scRNA-seq and spatial transcriptomics molecular profiling technologies in a normal and diseased fibrotic human liver. DGE analysis was performed over LSECs, and we identified the top 20 expressed genes in the periportal, perivenous, and intermediate acinar zones. Multi-omics and scRNA-seq analysis over Visium images and ECs liver cells showed OIT3, DNASE1L3, CLEC4G, LYVE1, FCN2, and CRHBP as commonly expressed mid-lobular zonation-specific genes. Also, this study detected STAB2, F8, AQP1, TEK, TIMP3, TIE1, and CTSL genes as expressed in DILI and NASH EC populations. The connection between LSEC marker genes in zone 2 and liver fibrosis holds significant promise for advancing our understanding in developing new therapeutic strategies for fibrosis reversal and designing computational molecular biomarkers in NASH and DILI fibrotic liver diseases.
