To ensure the infection efficiency of adeno-associated virus, 28 days after tail vein injection, we collected the livers of mice in the NC group, CXCL1 OE group, and CXCL1 KD group, sliced them and took pictures, and observed the expression of GFP in the livers (Supplemental Figure S3, http://links.lww.com/HC9/A507). This evidence concerns the gene CXCL1 and infection.
