FOS and lupus nephritis: FOS gene was downregulated in IgAN (p < 0.0001, Fold Change: −3.617), lupus nephritis (p < 0.001, Fold Change: −3.051), and diabetic nephropathy (p < 0.001, Fold Change: −2.672), focal segmental glomerulosclerosis (p < 0.0001, Fold Change: −2.822), and minimal change disease (p < 0.01, Fold Change: −2.689) (Figures 8F–J).
