Animal characteristics of studied NZW and NZB/W mice. Age, body weight, and relative kidney weight of NZW controls and NZB/W mice were shown in groups with different extent of renal damage at the end of the experiment.

	Age (weeks)	Body weight (g)	Kidney-to-body weight (mg/g)
NZW controls	30.6 ± 12.4 (n = 15)	30.5 ± 3.1 (n = 15)	7.5 ± 0.9 (n = 15)
NZB/W mild renal damage	27.9 ± 4.4 (n = 29)	33.4 ± 3,5c (n = 29)	6.6 ± 0.8 (n = 29)
NZB/W moderate renal damage	28.1 ± 4.1 (n = 24)	31.6 ± 3.8c (n = 23)	7.9 ± 2.1 (n = 23)
NZB/W severe renal damage	28.4 ± 3.8 (n = 18)	27.4 ± 5.7a,b (n = 18)	8.5 ± 1.1 (n = 18)

^a p < 0.05 vs. NZB/W mild renal damage.

^b p < 0.05 vs. NZB/W moderate damage.

^c p < 0.05 vs. NZB/W severe damage.
