Unfortunately, limited blood was obtained from the small CKD PHOSPHO1 KO mice and only serum creatinine concentrations were measured, and these did not differ between WT CKD mice (0.52 ± 0.02 mg/dL, n  = 4) and PHOSPHO1 KO CKD mice (0.49 ± 0.02 mg/dL, n  = 5) (NS). The gene discussed is PHOSPHO1; the disease is chronic kidney disease.
