Abstract
Heavy metal pollution is a problem that cannot be ignored. Due to the prevalence of cadmium in the environment and its harmful effects on humans, cadmium pollution has become a research hotspot recently. The mechanism of cadmium-induced toxicity has also drawn much attention and most studies have been conducted using whole cells, but the toxicological mechanism of cadmium remains unclear. In this study, we aimed to obtain NRK-52E cells at different growth stages by various methods and analyze the differences in cadmium toxicity. The results show that the cadmium sensitivity of cells in each phase was different and the late apoptotic rate was increased significantly after 5 µM Cd treatment. In addition, cadmium easily induces apoptosis of G0- and S-phase cells, as well as necrosis of S- and M-phase cells, but has no significant effect on G1-phase cells. Overall, we first explored the differences in the effects of cadmium on NRK-52E cells at various growth phases. Besides, the findings of this study might provide a theoretical basis for further exploration of the toxicological mechanism of cadmium.Abbreviations Cd: cadmium; CDK: cyclin-dependent kinases; DAPI 2-(4-amidinophenyl)-1H-indole-6-carboxamidine; TBST: Tris-buffered saline with Tween-20; PI: propidium iodide; DMEM: Dulbecco's Modified Eagle Medium; BCA: bicinchoninic acid.

Protective effects of dendropanoxide isolated from Dendropanax morbifera against cisplatin-induced acute kidney injury via the AMPK/mTOR signaling pathway. Food Chem Toxicol 2020; 145:111605. [PMID: 32750447 DOI: 10.1016/j.fct.2020.111605] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2020] [Revised: 07/07/2020] [Accepted: 07/09/2020] [Indexed: 12/11/2022]
Abstract
The aim of this study was to investigate the protective effects of dendropanoxide (DPx) isolated from Dendropanax morbifera against cis-diamminedichloroplatinum (II) (CDDP)-induced nephrotoxicity in NRK-52E cells and in Sprague-Dawley rats. DPx was administered to Sprague-Dawley rats by oral gavage (5 and 10 mg/kg) for 7 consecutive days, 24 h after intraperitoneal injection with CDDP (6 mg/kg). All rats were euthanized 24 h after the last DPx administration, and histopathological damage, acute kidney injury (AKI) biomarkers, inflammatory cytokines, and oxidative damages were evaluated. DPx (5 and 10 μg/mL) was found to protect against CDDP-induced cytotoxicity and apoptotic cell death in NRK-52E cells. CDDP-induced serum blood urea nitrogen (BUN), creatinine (sCr), and pro-inflammatory cytokines levels were significantly ameliorated by DPx in a dose-dependent manner. Furthermore, excretion of kidney injury molecules (KIM-1), selenium binding protein-1 (SBP-1), and neutrophil gelatinase-associated lipocalin (NGAL) in the urine was significantly reduced in response to DPx administration in CDDP-treated rats. Activities of antioxidant enzymes and lipid peroxidation levels were markedly altered in the kidney of CDDP-treated rats in response to DPx administration. Serum pro-inflammatory cytokine levels were dramatically suppressed by DPx in CDDP-treated rats. DPx also restored renal-cell apoptosis via regulation of AMPK/mTOR signaling in CDDP-treated rats. Our results clearly suggest that DPx ameliorates CDDP-induced nephrotoxicity in vitro and in vivo by inhibiting oxidative stress, inflammation, and apoptosis. Overall, our data demonstrates that DPx may serve as a therapeutic agent in patients with solid tumors to prevent CDDP-induced AKI.

Abstract
Background Tremendous growth in nanotechnology has opened up new frontiers in fundamental and applied aspects, including the synthesis of nanoscale matter and understanding/utilizing its exotic physicochemical and optoelectronic properties. Green-synthesis methods employing either biological microorganisms or plant extracts have emerged as a simple and alternative to chemical synthesis. Methods In our present study, we aimed to synthesize silver nanoparticles (AgNPs) in combination with an aqueous extract of Coptis chinensis (CC) using a suitable ecofriendly green-synthesis way. Results In our results, ultraviolet-visible spectroscopy revealed a near-absorbance peak at 450 nm, which confirmed the AgNP synthesis. The crystalline nature of the AgNPs was revealed with X-ray diffraction. Transmission electron-microscopy analysis showed spherically dispersed nanoparticles of 6–45 nm diameter. We analyzed the elementary mechanism across A549 lung carcinoma cells ahead of treatment with doses of CC-AgNPs (10 µg/mL and 25 µg/mL). The antiproliferative effect of CC-AgNPs revealed a significant decline in cell viability. Antibacterial assays with both Gram-negative (Escherichia coli) and Gram-positive (Staphylococcus aureus) bacteria exhibited a higher zone of inhibition against S. aureus. Conclusion Furthermore, CC-AgNPs regulated apoptosis using the intrinsic pathway to inhibit A549-cell proliferation. Proliferation migration and invasion were notably inhibited by CC-AgNPs, which promoted apoptosis in lung adenocarcinoma cells by regulating the apoptotic pathway.
