RNF34 and lupus nephritis: In parallel to the above, we retrieved RNA seq datasets from the Gene Expression Omnibus and assessed correlations among the gene abundances of ZFYVE21, Rubicon, and RNF34 in kidney tissues from renal transplant patients with CABMR (n = 110), synovial tissues from patients with RA (n = 23), and kidney tissues from patients with SLE nephritis (n = 21).
