Renal pathology scores in TgFVB and HIV-1 transgenic congenic and sub-congenic strains.

Albuminuria in TgFVB and the HIV-1 transgenic sub-congenic strains.
<p>Albuminuria is expressed as μg albumin/mg creatinine ratio. Statistically significant increase in albuminuria was observed in Sub-III and Sub-IV groups, but not in the Sub-II group when compared to TgFVB mice. (nonparametric P-value: *-p<0.05, **-p<0.01).</p
Map of the <i>HIVAN1</i> locus, congenic and sub-congenic regions.
<p>The rectangles depict the congenic and sub- congenic segments. The top line shows the position of the limiting markers in Mb (genome build 38p.3/mm10). The limiting markers with FVB genotypes are shown in blue, and those with CAST genotypes in red. The segments carrying CAST alleles are shown in grey. (Con = congenic strain)</p
Statistics summarized data; Discrimination between IgAN versus healthy and CKD controls for serum Gd-IgA1 and Gd-IgA1-specific IgG levels.

Serum levels of Gd-IgA1-specific IgG in IgAN patients with high-Gd-IgA1 or normal-Gd-IgA1 in comparison to CKD and healthy controls.
<p>We divided IgAN patients into two subgroups: patients with serum levels of Gd-IgA1 ≥ the 90<sup>th</sup> percentile for healthy controls (high-Gd-IgA1 group; n = 56) and patients with levels Gd-IgA1 < the 90<sup>th</sup> percentile for healthy controls (normal-Gd-IgA1 group; n = 79). Although serum levels of Gd-IgA1-specific IgG were significantly higher in IgAN patients with high Gd-IgA1 levels (<i>vs.</i> CKD controls; *P<0.0001, <i>vs.</i> healthy controls; **P<0.0001), IgAN patients with normal Gd-IgA1 levels also had elevated Gd-IgA1-specific IgG (<i>vs.</i> CKD controls; *P<0.0001, <i>vs.</i> healthy controls; **P<0.0001).</p

Correlation between biomarkers, histological findings and clinical findings.
<p>The strength of correlation between biomarkers, histological findings and clinical findings was measured by the Spearman's correlation coefficient. The serum level of Gd-IgA1-specific IgA correlated with the amount of mesangial IgA deposits (A). Histological prognostic stage (Clinical Guidelines for IgA Nephropathy in Japan, second version) <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0098081#pone.0098081-Tomino1" target="_blank">[17]</a> correlated with the urinary protein/creatinine ratio (B), and percentage of glomeruli with a crescent (C).</p
Distribution of serum levels of (A) Gd-IgA1, (B) Gd-IgA1-specific IgG and (C) Gd-IgA1-specific IgA in patients with IgAN (n = 135), CKD controls (n = 79) and healthy controls (n = 106).
<p>Each biomarker was measured by capture ELISA. The serum levels of Gd-IgA, Gd-IgA1-specific IgG and Gd-IgA1-specific IgA were higher in IgAN patients compared with those of the CKD controls (*P<0.001) and healthy controls (**P<0.0001).</p
