Background: DBA/2FG-pcy (pcy) mice harbor a homozygous Nphp3 missense mutation and develop nephronophthisis with renal interstitial fibrosis. Previous studies have shown that aberrant oxygen homeostasis contributes to the renal pathology in pcy mice, but the underlying molecular mechanism remains largely unknown. Methods: pcy mice and a control strain, DBA/2N (DBA) mice, were used. Renal levels of 62 mRNAs involved in oxygen homeostasis were investigated by real-Time PCR, and the resulting data were used for extraction of pathological pathways. On the basis of the genes found to be upregulated and pathway analysis, further studies were performed using immunoblotting, immunohistochemistry, and pharmacological intervention. Results: In comparison with DBA mice, the levels of 18 mRNAs were altered by >2-fold in pcy mice. Pathway analysis extracted molecular pathways related to oxidative stress, inflammation, and cell adhesion. As the levels of mRNAs relevant to the NADPH oxidase 2 (NOX2) pathway were prominently (4 genes >5-fold) increased in pcy mice, we further analyzed the molecules related to this pathway. A time course study suggested that the pathway was gradually activated in pcy mice from at least 5 weeks of age. Immunohistochemistry study revealed that NOX2 protein was colocalized with a macrophage marker protein in the renal interstitium. Moreover, treatment of pcy mice with apocynin, an inhibitor of the NOX2 pathway, ameliorated the renal fibrosis. Conclusion: Our findings suggest that the activation of the NOX2 pathway, possibly mediated by macrophage infiltration, plays a pivotal role in progressive renal fibrosis in pcy mice.

Although several studies have shown that release of water channel proteins, aquaporin 1 (AQP1) and AQP2 in urinary extracellular vesicles (uEV-AQP1 and -AQP2), were altered in experimental kidney injury models, their release in human chronic kidney disease (CKD) has been largely unexplored. The aim of the present study was to clarify whether the release of uEV-AQP1 and -AQP2 is altered in patients with CKD. Urine samples were collected from 15 healthy volunteers (normal group) and 62 CKD patients who were categorized into six glomerular filtration rate (GFR) categories (G1, G2, G3a, G3b, G4, and G5) in between 2005 and 2016 at Miyazaki Prefectural Miyazaki Hospital, Japan. uEV-proteins were evaluated by immunoblot analysis. The release of AQP1 and AQP2 were significantly decreased in patients with both CKD G4 and G5, in comparison with the normal group. The area under the receiver operating characteristic (ROC) curve (AUC) values for AQP1 and AQP2 in patients with CKD G4 and G5 were 0.926 and 0.881, respectively. On the other hand, the AUC values in patients with CKD G1-G3 were 0.512 for AQP1 and 0.680 for AQP2. Multiple logistic regression analysis showed that AQP1 and AQP2 in combination were useful for detecting CKD G4 and G5, with a higher AUC value of 0.945. These results suggest that the release of uEV-AQP1 and -AQP2 was decreased in patients with CKD G4 and G5, and these proteins might be helpful to detect advanced CKD.

The aim of this study was to evaluate the involvement of nanoparticles prepared from Allium cepa L. as anti-inflammatory agents. In the present study, we identified nanoparticles from Allium cepa L. using the ultracentrifugation exosome purification method. The nanoparticles were referred to as 17,000× g and 200,000× g precipitates, and they contained quercetins, proteins, lipids, and small-sized RNA. The nanoparticles inhibited nitric oxide production from lipopolysaccharide (LPS)-stimulated RAW264 cells without cytotoxic properties. Cellular incorporation was confirmed by laser microscopic observation after PKH26 staining. The inhibition of caveolae-dependent endocy-tosis and macropinocytosis significantly prevented the incorporation of the nanoparticles but had no effect on the inhibition of nitric oxide in RAW264 cells. Collectively, the identified nanoparticles were capable of inhibiting the LPS response via extracellular mechanisms. Taken together, the way of consuming Allium cepa L. without collapsing the nanoparticles is expected to provide an efficient anti-inflammatory effect.

腎疾患は医療および獣医領域において罹患率および死亡率の高い疾患で、有用な早期診断マーカーがないことが問題となっている。本研究では非侵襲的に得ることのできる尿にexosomeと呼ばれる小胞が含まれることに着目した。このexosomeには由来細胞のタンパク質やmRNA、miRNA（RNAs）が含まれており、これらはその由来細胞の状態を反映したバイオマーカーとなる可能性が考えられる。本研究はタンパク質よりも解析が簡便なRNAsに着目し、薬剤性腎障害ラットモデルを用いて尿中exosome RNAsの腎疾患バイオマーカーとしての有用性を検討することを目的として行う。

尿中エクソソームアクアポリン1およびアクアポリン2排泄の生理的調節機構の基礎研究

Authorship：Principal investigator
尿中には尿細管上皮細胞由来の小胞、エクソソームが存在しており、エクソソームにはその由来細胞のタンパク質やmRNAが含まれている。尿中エクソソームタンパク質やmRNAは、その由来する細胞の傷害における非侵襲的診断マーカーとして有用であると期待されている。申請者はこれまでに、尿中エクソソームに含まれる水チャネルアクアポリン１（AQP1）およびアクアポリン2（AQP2）タンパク質が急性腎障害早期診断マーカーとして有用である可能性を見出した。しかしながら、これらのタンパク質の生理的尿中排泄調節機構については明らかにされていない。本研究は、尿中エクソソームAQP1およびAQP2タンパク質、さらにはmRNAの診断マーカーとしての有用性を確立するためのバックグラウンドとしてこれらの生理的尿中排泄調節機構について明らかにすることを目的とする。
