Figure 3: OXR1 expression in kidney in murine lupus and SLE patients with LN. OXR1 expression in B6, B6.Sle1.Sle3, B6.Sle1.Sle2.Sle3, and MRL/lpr. Female mice aged to 8 months. OXR1 expression in renal cortex of control subjects and SLE patients with LN II-IV. OXR1 expression in renal medulla of control subjects and SLE patients with LN II-IV.
