Factor Xa inhibitor, edoxaban ameliorates renal injury after subtotal nephrectomy by reducing epithelial-mesenchymal transition and inflammatory response.
Chronic kidney disease (CKD) is an increasing and life-threatening disease worldwide. Recent evidence indicates that blood coagulation factors promote renal dysfunction in CKD patients. Activated factor X (FXa) inhibitors are safe and first-line drugs for the prevention of thrombosis in patients with atrial fibrillation. Here, we investigated the therapeutic effects of edoxaban on CKD using the mouse 5/6 nephrectomy model. Eight-week-old wild-type mice were subjected to 5/6 nephrectomy surgery and randomly assigned to two groups, edoxaban or vehicle admixture diet. Edoxaban treatment led to reduction of urinary albumin excretion and plasma UN levels compared with vehicle group, which was accompanied with reduced glomerular cross-sectional area and cell number. Edoxaban treatment also attenuated fibrinogen positive area in the remnant kidneys after subtotal nephrectomy. Moreover, edoxaban treatment resulted in attenuated tubulointerstitial fibrosis after 5/6 nephrectomy, which was accompanied by reduced expression levels of epithelial-mesenchymal transition (EMT) markers, inflammatory mediators, and oxidative stress markers in the remnant kidneys. Treatment of cultured proximal tubular cells, HK-2 cells, with FXa protein led to increased expression levels of EMT markers, inflammatory mediators, and oxidative stress markers, which were abolished by pretreatment with edoxaban. Treatment of HK-2 cells with edoxaban attenuated FXa-stimulated phosphorylation levels of extracellular signal-regulated kinase (ERK) and NF-κB. Our findings indicate that edoxaban can improve renal injury after subtotal nephrectomy by reducing EMT and inflammatory response, suggesting that FXa inhibition could be a novel therapeutic target for CKD patients with atrial fibrillation.

Effects of edoxaban and warfarin on vascular remodeling: Atherosclerotic plaque progression and collateral artery growth.
Oral anticoagulation prevents thromboembolism in atrial fibrillation. Factor Xa inhibitors, like edoxaban, are known to reduce inflammation and proliferation of smooth muscle cells, while vitamin K antagonism can cause vascular calcific damage. The influence of edoxaban compared to warfarin on vascular remodeling, atherosclerosis and arteriogenesis is unknown.. Apolipoprotein E knockout (ApoE. There was no difference in hind-limb perfusion restoration between the three groups after 14 days (Co 0.36 ± 0.05 vs. Warf 0.39 ± 0.09 (p = .39), Co vs. Edo 0.51 ± 0.06 (p = .089), Warf vs. Edo (p = .83)) after ligation. Immuno-histologically, there was no difference in smooth muscle cell count in both hindlimbs between the three groups or in the amount of perivascular macrophages in collateral-bearing hindlimb tissue. Edoxaban showed the lowest amount of plaque tissue in the aortic sinus tissue (Co 74 ± 11% vs. Edo 62 ± 12% (p = .024), Co vs. Warf 69 ± 14% (p = .30), Edo vs. Warf (p = .14)) as well as the least amount of fibrosis (Co 3.1 ± 0.9% vs. Edo 1.7 ± 0.6% (p = .027), Co vs. Warf 4.1 ± 0.7% (p = .081), Edo vs. Warf (p < .001)). No difference in mRNA content of inflammatory cytokines in muscle tissue or spleen was detected between the three groups.. These data suggest that treatment with edoxaban unlike warfarin prevents vascular maladaptive remodeling, which may be clinically important.

Edoxaban suppresses the progression of atrial fibrosis and atrial fibrillation in a canine congestive heart failure model.
Coagulation factor Xa activates the protease-activated receptor 2 (PAR2) and causes tissue fibrosis; however, the effects of Xa inhibitor edoxaban on atrial fibrosis and atrial fibrillation (AF) have not been investigated. We examined the effect of edoxaban on the progression of atrial fibrosis in a canine congestive heart failure (CHF) model. Beagle dogs were assigned to sham, placebo, and edoxaban groups (n = 6/group). Dogs of the placebo or edoxaban groups received 19 days of medication with daily oral placebo or edoxaban, respectively, followed by 14 days of ventricular tachypacing. Dogs of the sham group had no medication or pacing. Ventricular tachypacing prolonged AF duration in dogs of the placebo group (159 ± 41 s, p < 0.01 vs. sham); however, this effect was suppressed by edoxaban treatment. Compared with the sham group, tachypacing alone also significantly increased the atrial fibrotic area (2.9 ± 0.1% vs. 7.8 ± 0.4%, p < 0.01), PAR2 expression (1.0 ± 0.1 vs. 1.8 ± 0.3, p < 0.05), and atrial fibronectin expression (1.0 ± 0.2 vs. 2.0 ± 0.2, p < 0.01). These responses were suppressed by edoxaban treatment (area 5.9 ± 0.4%, p < 0.01; PAR2 1.1 ± 0.1, p < 0.05; fibronectin 1.2 ± 0.2, p < 0.05 vs. placebo). Edoxaban showed suppressive effects on atrial remodeling, AF progression, and excessive expressions of PAR2 and fibronectin in a canine CHF model. The suppression of the Xa/PAR2 pathway might be a potential pharmacological target of edoxaban.
