Expression data from the cardiac tissue of Wild Type (WT) and ACKR4-knockout (ACKR4-KO) mice

Purpose:Atypical classical chemokine receptor 4 (ACKR4) is a newly reported atypical classical chemokine receptor. However, its expression and role in MI are still unknown. This study aims to determine whether ACKR4 modulates cardiac remodeling following MI and to explore the specific molecular mechanism. Methods: RNA sequencing of infarcted hearts from WT and ACKR4-KO mice was performed at day 14 post-MI. Results: We generated a library of distinct transcriptome expression patterns.The consistency in the clustering suggested a homogeneous genomic activity with limited background signal and high levels of reproducibility across the three biological replicates in each group.Utilizing a P value < 0.05 and fold changes of 1.5 or greater, we identified 774 genes that are differentially expressed in ACKR4-KO mice compared to WT mice.The downregulated-genes belonged to the GO classes taxis, chemotaxis, extracellular matrix, and cytokine activity. Conclusions: These data provide the first insight into the role and mechanism of ACKR4 in MI. Cardiac mRNA profiles of WT and ACKR4-KO mice at day 14 post-MI.
