We hypothesize that the stimulation of PPAR-γ expression and interference with miR-17-5p activated Wnt-β-catenin signaling mediates the antifibrotic properties of Dios.

The present study was designed to evaluate the effect of cranberry extract (CRAN) and/or losartan (LOS) against aluminium chloride (AlCl) induced hepatorenal damage associated cardiomyopathy in rats. To induce hepatorenal and cardiotoxicity, animals were received (AlCl; 70 mg/kg i.p.) for 8 weeks day after day and treated with CRAN (100 mg/kg b.wt.) orally daily for 4 weeks started after 4 weeks from AlCl injection accompanied with an administration of LOS (5 mg/kg i.p.) three times weekly for 4 weeks. Our data revealed that, compared to AlCl, administration of CRAN extract and LOS produced a significant improvement which was evidenced by a significant amelioration in myocardial and vascular indices, kidney and liver markers, lipid profile and oxidative stress indices. Furthermore, histopathological and immunohistochemical examination reinforced the previous results. It could be concluded that combination of CRAN extract and LOS hindered AlCl induced hepatorenal damage complicated cardiomyopathy in rats.

The present investigation aimed to evaluate the radiomitigative efficacy of the recombinant human erythropoietin (EPO) against acute radiation syndrome (ARS) in a rat model. Rats were irradiated with a single sublethal dose of γ-radiation (7 Gy; total body irradiation; TBI) on the 1st day of experimental course, then received EPO (5000 IU/kg; i.p.) 24 h after irradiation, and rats were observed for 30 days of survival analysis. Administration of EPO improved 30-day survival, alleviated TBI-induced myelosuppression and pancytopenia, by augmenting lymphocytes and other white blood cells in the peripheral blood of rats, while bone marrow and spleen cellularity were restored. EPO post-exposure treatment alleviated hepatotoxicity biomarkers and restored splenic function. EPO abrogated radiation-induced oxidative stress through the upregulation of the cholinergic anti-inflammatory nicotinic acetylcholine receptor (α-7-nAChR) and the pro-survival Janus kinase-2 and signal transducers and activators of transcription JAK-2/STAT-3 signaling mediated via enhancing nuclear factor erythroid-2 related factor-2 (Nrf-2) cytoprotective machinery in liver and spleen of irradiated rats. Moreover, EPO treatment prevented hepatic and splenic apoptosis. The present study establishes the implication of α-7-nAChR-JAK-2/STAT-3-Nrf-2 signaling cascade in the radiomitigative potential of EPO against ARS.
