Abstract
BACKGROUND AND AIM Necrotizing Enterocolitis (NEC) is an inflammation-associated ischemic necrosis of the intestine. To investigate the effects of extra virgin olive oil (EVOO) on inflammation, oxidative stress, apoptosis, and histological changes in NEC-induced newborn rats. MATERIALS AND METHODS 24 rats were randomly divided into three groups: control, NEC and NEC + EVOO. NEC induction was performed using hypoxia-hyperoxia, formula feeding, and cold stress. The NEC + EVOO group received 2 ml/kg EVOO with high phenolic content by gavage twice a day for 3 days. 3 cm of bowel including terminal ileum, cecum, and proximal colon was excised. RESULTS Weight gain and clinical disease scores were significantly higher in the NEC + EVOO group than in the NEC group (p < 0.001). EVOO treatment caused significant decreases in IL1β, IL6 levels (p = 0.016, p = 0.029 respectively) and EGF, MDA levels (p = 0.032, p = 0.013 respectively) compared to NEC group. Significant decreases were observed in IL6 gene expression in the NEC + EVOO group compared to the NEC group (p = 0.002). In the group NEC + EVOO, the number of Caspase-3 positive cells was found to be significantly reduced (p < 0.001) and histopathological examination revealed minimal changes and significantly lower histopathological scores (p < 0.001). CONCLUSION Phenol-rich EVOO prevents intestinal damage caused by NEC by inhibiting inflammation, oxidative stress, apoptosis.

Liu Y, Zhang L, Chen X, Sun C, Zhang Y, Li Y, Li C. Functional characterization of porcine nucleophosmin (NPM1) gene in promoting the replication of Japanese encephalitis virus and induction of inflammatory cytokines. DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2023; 148:104902. [PMID: 37536401 DOI: 10.1016/j.dci.2023.104902] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/08/2023] [Revised: 07/31/2023] [Accepted: 07/31/2023] [Indexed: 08/05/2023]
Abstract
Nucleophosmin (NPM1) is a multifunctional nucleolar protein that plays a role in cell cycle control, tumorigenesis, induction of the inflammatory cytokine, virus replication, as well as the cellular responses to a variety of stress stimuli. However, its physiological functions in pigs have not been well understood. Here, we cloned the porcine NPM1 (porNPM1) gene and analyzed the functions of the porNPM1 protein in pigs. The full-length porNPM1 gene encoded a 294-amino acid protein with 94.5%-99.3% sequence identity to its orthologues in mammals and was extensively expressed in various pig tissues at the mRNA level. The porNPM1 primarily localizes in the nucleus of ST cells, while it translocates from the nucleus to nucleoplasm upon UV irradiation or H2O2 treatment. Notably, JEV infection blocked the translocation of porNPM1 from the nucleolus to the nucleoplasm. Furthermore, porNPM1 interacted with the JEV C protein and facilitated JEV replication in ST cells. The overexpression and knockdown of porNPM1 respectively enhanced or impaired JEV replication, suggesting the important role of porNPM1 in JEV replication. Additionally, the purified ectodomain of porNPM1 induced the production of inflammatory cytokines (TNF-α, IL-6, and IL-8). Together, these data demonstrated that porNPM1 is involved in cellular stress stimuli, JEV replication, and induction of inflammatory cytokines.

Abstract
Aim: Lung cancer is the leading cause of mortality from cancer across the world. In this study, the use of serum nucleolin (NCL) and nucleophosmin (NPM1) levels as a marker in the diagnosis, prognosis and treatment response evaluation in lung cancer was investigated. Materials and Method: NCL and NPM1 levels of serum samples taken before chemotherapy and after 3-4 courses of chemotherapy from the control group and the patients diagnosed with lung cancer were studied using ELISA method. Results: Serum NCL and NPM1 levels of the patients were higher than of the controls (p = 0.085 for NCL, p = 0.000 for NPM1). NCL and NPM1 levels by histopathologic type were significantly higher in adenocarcinoma than in squamous cell carcinoma (p < 0.05 for each). In view of the treatment responses to chemotherapeutic agents, there was a statistically insignificant difference between the values before and after chemotherapy (p > 0.05 for each). Conclusion: High serum NCL and NPM1 levels were found to correlate with poor prognosis, poor treatment response and low survival rate. It can be concluded that serum NCL and NPM1 levels in lung cancer can be used as diagnostic and prognostic markers for the disease.
