Correlation analysis of miR-210, miR-494, and miR-205 with biochemical indices of kidney injury (BUN, Cr, and cystatin C). A positive correlation was identified between miR-210 and miR-494 plasma expression and BUN, Cr and cystatin C serum levels; whereas, a negative correlation was found between miR-205 plasma expression and BUN, Cr and cystatin C serum levels in patients with sepsis-induced AKI (p < 0.05). BUN: Blood urea nitrogen; Cr: Creatinine; miR: microRNA; AKI: Acute kidney injury.
