Human MiR-4660 regulates the expression of alanine–glyoxylate aminotransferase and may be a biomarker for idiopathic oxalosis

Background Dysfunction of oxalate synthesis can cause calcium oxalate stone disease and inherited primary hyperoxaluria (PH) disorders. PH type I (PH1) is one of the most severe hyperoxaluria disorders, which results in urolithiasis, nephrocalcinosis, and end-stage renal disease. Here, we sought to determine the role of microRNAs in regulating AGXT to contribute to the pathogenesis of mutation-negative idiopathic oxalosis.
