ERBB4 and acute kidney injury: The results indicated that two miRNAs (miR-203a-3p and miR-205-5p) and ERBB4 might play a central role in post-Tx AKI, and the biological functions of the regulatory miRNA–mRNA network were enriched in kidney-/renal-related functions and PI3K–Akt/HIF-1/Ras/MAPK signaling pathways.
