As for u-Gal-3BP, the ratio between the protein and its binding partner Gal-3 (u-Gal-3BP/u-Gal-3), also differed across the groups (p < .0001, Figure 1(c)), with LN patients showing higher ratios than ANR-SLE, INR-SLE patients and PBC (p < .0001 for each comparison). Here, LGALS3 is linked to primary biliary cholangitis.
