Abstract
OBJECTIVES Paeonol (PAE) is an active ingredient with anti-inflammatory and antioxidant properties. This study was designed to investigate the effect of PAE on acute pancreatitis (AP). METHODS AP was induced by the intraperitoneal injection of 20% l-arginine (4 g/kg) for 6 h. Mice were pretreated with PAE (25, 50 or 100 mg/kg) intragastrically for 5 days. The histological damage and alterations of biochemical indicators, inflammatory cytokines and oxidative stress factors in AP mice were detected. The Nrf2 and NF-κB pathways were examined to illustrate the potential mechanism. KEY FINDINGS In AP model, we found that PAE attenuated histological injury of pancreatic tissues, reduced the serum levels of α-amylase and increased Ca2+ contents in a dose-dependent manner. The white blood cell content, and IL-1β, IL-6 and TNF-α levels in the serum of AP mice were reduced by PAE. Furthermore, PAE caused a reduction of MPO and MDA levels, accompanied by an increase in SOD activity in the pancreas of AP mice. We also demonstrated that the alterations of Nrf2 and NF-κB pathways in AP mice were reversed by PAE. CONCLUSIONS PAE attenuates inflammation and oxidative stress in the development of AP by the regulation of Nrf2 and NF-κB pathways.

The role and clinical significance of long noncoding RNA zinc finger E-box-binding homeobox two antisense RNA 1 in promoting osteosarcoma cancer cell proliferation, inhibiting apoptosis and increasing migration by regulating miR-145. Anticancer Drugs 2020; 32:168-177.

Abstract
We aimed to investigate the expression level of long noncoding RNA (lncRNA) zinc finger E-box-binding homeobox two antisense RNA 1 (ZEB2-AS1) in osteosarcoma and explore its possible regulatory mechanisms. Expression of lncRNA ZEB2-AS1 was detected by quantitative real-time PCR in 63 cancerous tissues and 25 adjacent normal mucosal tissues from patients with osteosarcoma. The correlation between the lncRNA ZEB2-AS1 level and clinicopathological characteristics of the osteosarcoma patients were evaluated, and 5-year overall survival (5OS) was also analyzed according to lncRNA ZEB2-AS1 expression. The ZEB2-AS1 and miR-145 recombinant expression vector was used to analyze their relationship in an in vitro cell system. Luciferase reporter gene assays and RNA immunoprecipitation assays were used to verify the interaction between ZEB2-AS1 and miR-145. The proliferation, apoptosis and migration of osteosarcoma cells were determined by Cell counting kit-8 assays, Annexin V-PI assays and transwell assays, respectively. A significantly increased level of lncRNA ZEB2-AS1 with a fold change of 3.86 was found in osteosarcoma tissues compared with control tissues (P < 0.001). The Chi-square test revealed that lncRNA ZEB2-AS1 expression in osteosarcoma was significantly different according to radiology classification (P = 0.018), TNM stage (P = 0.000) and survival status (P = 0.005). The 5OS was 18.4% and 52% in osteosarcoma patients with higher and lower lncRNA ZEB2-AS1 expression, respectively. Significantly increased ZEB2-AS1 expression was found in osteosarcoma cells, while decreased levels of miR-145 were confirmed in osteosarcoma tissues and cell lines compared to controls. Moreover, a negative correlation was found between the expression level of ZEB2-AS1 and miR-145 in osteosarcoma tissues (R2 = 0.71, P < 0.01). ZEB2-AS1 knockdown resulted in decreased osteosarcoma cell proliferation, increased apoptosis and reduced migration. In addition, negative regulation of miR-145 by ZEB2-AS1 in osteosarcoma cells was also observed, and the effects of ZEB2-AS1 on osteosarcoma cells were found to be regulated by miR-145. Significantly upregulated lncRNA ZEB2-AS1 expression in osteosarcoma patients influences the prognosis of patients, and ZEB2-AS1 accelerates tumorigenesis and osteosarcoma development by downregulating miR-145.

Isoliquiritigenin Ameliorates Acute Pancreatitis in Mice via Inhibition of Oxidative Stress and Modulation of the Nrf2/HO-1 Pathway. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2018; 2018:7161592. [PMID: 29854090 PMCID: PMC5944199 DOI: 10.1155/2018/7161592] [Citation(s) in RCA: 117] [Impact Index Per Article: 19.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/14/2017] [Revised: 02/17/2018] [Accepted: 03/20/2018] [Indexed: 02/06/2023]
Abstract
Oxidative stress plays a crucial role in the pathogenesis of acute pancreatitis (AP). Isoliquiritigenin (ISL) is a flavonoid monomer with confirmed antioxidant activity. However, the specific effects of ISL on AP have not been determined. In this study, we aimed to investigate the protective effect of ISL on AP using two mouse models. In the caerulein-induced mild acute pancreatitis (MAP) model, dynamic changes in oxidative stress injury of the pancreatic tissue were observed after AP onset. We found that ISL administration reduced serum amylase and lipase levels and alleviated the histopathological manifestations of pancreatic tissue in a dose-dependent manner. Meanwhile, ISL decreased the oxidative stress injury and increased the protein expression of the Nrf2/HO-1 pathway. In addition, after administering a Nrf2 inhibitor (ML385) or HO-1 inhibitor (zinc protoporphyrin) to block the Nrf2/HO-1 pathway, we failed to observe the protective effects of ISL on AP in mice. Furthermore, we found that ISL mitigated the severity of pancreatic tissue injury and pancreatitis-associated lung injury in a severe acute pancreatitis model induced by L-arginine. Taken together, our data for the first time confirmed the protective effects of ISL on AP in mice via inhibition of oxidative stress and modulation of the Nrf2/HO-1 pathway.
