Figure Lengend Snippet: P2Y2R deficiency protects against podocyte loss and glomerular injury in DN. (A) Relative mRNA levels of Nphs1 (nephrin) and Nphs2 (podocin) were determined by real-time PCR analysis (n = 3–5). (B) Localisation of WT1, a podocyte marker, was analysed by immunohistochemistry, and representative images are shown. The number of stained podocytes per glomeruli was counted by using ImageJ software (n = 3). (C) Kidney sections were stained with PAS staining and glomerular morphological changes were scored as described in the method section (n = 3). Data are presented as mean ± SEM. One-way ANOVA was used for statistical analysis followed by Bonferroni's multiple comparisons test. ∗∗∗p < 0.001 vs WT control mice; and ### p < 0.001 vs WT DN mice. Scale bar, 50 μm.

Figure Lengend Snippet: Mesangial defects in FoxD1 GC ;Dicer fl/fl mature glomeruli at E18.5. (A–D) Immunofluorescence staining for Desmin (red) showed evidence for early mesangial cell migration in both control ( n = 3 embryos, 25 comma-/s-shaped bodies) and FoxD1 GC ;Dicer fl/fl ( n = 3 embryos, 16 comma-/s-shaped bodies) developing WT1 + (red) comma- and s-shaped bodies. (E, F) Developing capillary loop nephrons as marked by expression of Lef1 (red) in early podocytes showed evidence for Pdgfr β + (green) mesangial formation in FoxD1 GC ;Dicer fl/fl kidneys ( n = 3 embryos, 49 glomeruli), although the mesangial network appeared simplified when compared to controls ( n = 3 embryos, 52 glomeruli). (G–L) Mature FoxD1 GC ;Dicer fl/fl glomeruli displayed overt mesangial abnormalities as evident by a significant reduction in Pdgfr β + (green) and Desmin + (red) immunoreactivity. (M–O) Semiquantitative analysis revealed no significant difference in developing WT1 + comma- and s-shaped bodies (M) or Lef1 + early glomeruli (N) in control and FoxD1 GC ;Dicer fl/fl embryos. However, there were significantly fewer WT1 + mature glomeruli with a Desmin + mesangial network in FoxD1 GC ;Dicer fl/fl kidneys ( n = 3 embryos, 29 glomeruli, **** P < 0.0001), when compared to controls ( n = 3 embryos, 19 glomeruli) (O). The presence of WT1 + (red) podocytes and intussuscepted Pecam + (red) capillaries in the FoxD1 GC ;Dicer fl/fl glomeruli suggest that the mesangial defects are likely to be a primary consequence of loss of stromal miRNAs.
