UTX plays a pivotal role in regulating MLCK expression. a, b UTXf/f SCMECs Vs UTX−/− SCMECs were significantly different (p ≤ 0.05, logFC ≥ 1 or ≤ − 1) from heatmap and volcano map of RNA expression profiles. c Venn diagram of the intersection of differential genes screened by RNA-seq and genes associated with vascular permeability retrieved from GSEA and MGI databases. d Differential ploidy of the genes screened in c. e qRT-PCR verification of the mRNA levels of MYLK (MLCK), BMP6, and AKAP12 in the UTXf/f and UTX−/− mice at 3 days post-SCI. n = 3 per group. f Representative immunofluorescence images of MLCK (red) and CD31 (green), DAPI (blue) staining of injured epicenter of spinal cord at SCI 3d.
