Figure 4. Hepatocyte-specific METTL3 homozygous ablation by Alb-iCre mice (GPT) causes apoptosis in mouse hepatocytes. (A, B) Representative TUNEL staining photographs (A) and quantification of TUNEL-positive hepatocytes of paraffin-embedded liver sections from control mice and METTL3Δhep mice (GPT) at 7 or 14 days after birth. Scale bar = 100 μm. (C) qRT-PCR analysis of the expression of apoptosis-related genes in the liver of METTL3Δhep mice (GPT). (D) Hierarchical clustering of differentially expressed genes (DEG) related to apoptosis in the liver of control mice and METTL3Δhep mice (GPT) at 1 week after birth from RNA-seq data deposited in GEO under accession number GSE198512 [
