As shown in Table 6, compared with normal kidney tissues, tubular BBOX1 mRNA expression was either not significantly changed or slightly upregulated in other types of CKD including hypertensive nephropathy (relative expression: 0.929, adjusted p = 0.438), focal segmental glomerulosclerosis (relative expression: 1.17, adjusted p = 0.134), IgA nephropathy (relative expression: 0.965, adjusted p = 0.662) and membranous nephropathy (relative expression: 1.28, adjusted p = 0.0045). Here, BBOX1 is linked to focal segmental glomerulosclerosis.
