Abstract
In this study, we investigated the effects of supplemental Glycyrrhiza polysaccharide (GCP) on growth performance and intestinal health of weaned piglets. Ninety piglets weaned at 28 days of age were randomly allocated to three groups with five replicates per treatment. Piglets were fed the following diets for 28 days: (1) CON (control group), basal diet; (2) G500, CON + 500 mg/kg GCP; (3) G1000, CON + 1000 mg/kg GCP. The results showed that supplementation with 1000 mg/kg GCP increased the average daily gain (ADG) and decreased the feed-to-gain ratio (F/G) (P < 0.05). Serum diamine oxidase (DAO) and D-lactic acid (DL-A) levels were lower in the G1000 group (P < 0.05). Dietary GCP 1000 mg/kg improved mucosal trypsin activity in the duodenum, jejunum and ileum and increased lipase and amylase activity in the jejunum (P < 0.05). Moreover, in the G1000 group, ZO-1, claudin 1 and occludin levels were increased in the jejunum mucosa, whereas interleukin-1β (IL-1β) and IL-6 levels were decreased (P < 0.05). The 16S rRNA gene analysis indicated that dietary 1000 mg/kg GCP altered the jejunal microbial community, with increased relative abundances of beneficial bacteria. In conclusion, dietary GCP 1000 mg/kg can improve growth performance, digestive enzyme activity, intestinal immunity, barrier function and microbial community in weaned piglets.

ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2024; 273:116161. [PMID: 38430581 DOI: 10.1016/j.ecoenv.2024.116161] [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: 11/22/2023] [Revised: 02/23/2024] [Accepted: 02/25/2024] [Indexed: 03/04/2024]
Abstract
Di(2-ethylhexyl) phthalate (DEHP) is a worldwide common plasticizer. Nevertheless, DEHP is easily leached out to the environment due to the lack of covalent bonds with plastic. High dose of DEHP exposure is often observed in hemodialysis patients because of the continual usage of plastic medical devices. Although the liver is the major organ that catabolizes DEHP, the impact of long-term DEHP exposure on the sensitivity of liver cancer to chemotherapy remains unclear. In this study, we established long-term DEHP-exposed hepatocellular carcinoma (HCC) cells and two NOD/SCID mice models to investigate the effects and the underlying mechanisms of long-term DEHP exposure on chemosensitivity of HCC. The results showed long-term DEHP exposure potentially increased epithelial-mesenchymal transition (EMT) in HCC cells. Next generation sequencing showed that long-term DEHP exposure increased cell adhesion/migratory related genes expression and blunted sorafenib treatment induced genes alterations. Long-term exposure to DEHP reduced the sensitivity of HCC cells to sorafenib-induced anti-migratory effect by enhancing the EMT transcription factors (slug, twist, and ZEB1) and mesenchymal protein (vimentin) expression. In NOD/SCID mice model, we showed that long-term DEHP-exposed HCC cells exhibited higher growth rate. Regarding the anti-HCC effects of sorafenib, subcutaneous HuH7 tumor grew slowly in sorafenib-treated mice. Nonetheless, the anti-tumor growth effect of sorafenib was not observed in long-term DEHP-exposed mice. Higher mesenchymal markers and proliferating cell nuclear antigen (PCNA) expression were found in sorafenib-treated long-term DEHP-exposed mice. In conclusion, long-term DEHP exposure promoted migratory activity in HCC cells and decreased sorafenib sensitivity in tumor-bearing mice.

Abstract
The application of immunotherapy in tumor, especially immune checkpoint inhibitors (ICIs), has played an important role in the treatment of advanced unresectable liver cancer. However, the efficacy of ICIs varies greatly among different patients, which has aroused people's attention to the regulatory mechanism of programmed death ligand-1 (PD-L1) in the immune escape of liver cancer. PD-L1 is regulated by multiple levels and signaling pathways in hepatocellular carcinoma (HCC), including gene variation, epigenetic inheritance, transcriptional regulation, post-transcriptional regulation, and post-translational modification. More studies have also found that the high expression of PD-L1 may be the main factor affecting the immunotherapy of liver cancer. However, what is the difference of PD-L1 expressed by different types of cells in the microenvironment of HCC, and which type of cells expressed PD-L1 determines the effect of tumor immunotherapy remains unclear. Therefore, clarifying the regulatory mechanism of PD-L1 in liver cancer can provide more basis for liver cancer immunotherapy and combined immune treatment strategy. In addition to its well-known role in immune regulation, PD-L1 also plays a role in regulating cancer cell proliferation and promoting drug resistance of tumor cells, which will be reviewed in this paper. In addition, we also summarized the natural products and drugs that regulated the expression of PD-L1 in HCC.

Abstract
Plasticizer di(2-ethylhexyl) phthalate (DEHP) is employed to make polyethylene polymers. Some studies in epidemiology and toxicology have shown that DEHP exposure over an extended period may be hazardous to the body, including nephrotoxicity, and aggravate kidney damage in the context of underlying disease. However, studies on the toxicity of DEHP in diabetes-induced kidney injury have been rarely reported. Using a high-fat diet (HFD) and streptozotocin (STZ, 35 mg/kg)-induced kidney injury in mice exposed to various daily DEHP dosages, we explored the impacts of DEHP on diabetes-induced kidney injury. We discovered that DEHP exposure significantly promoted the renal inflammatory response and oxidative stress in mice, with increased P-p38 and P-p65 protein levels and exacerbated the loss of podocin. The same findings were observed in vitro after stimulation of podocytes with high glucose (30 mmol/L) and exposure to DEHP. Our results suggest that DEHP exacerbates diabetes-induced kidney injury by mediating oxidative stress and activating p38MAPK/NF-κB.

Abstract
Di-(2-ethylhexyl)phthalate (DEHP) is an endocrine-disrupting chemical (EDC) that induces epigenetic alterations, apoptosis, and oxidative stress after biological exposure. MicroRNAs (miRNAs) are a class of small noncoding RNAs with many regulatory functions and play a role in organisms exposed to environmental chemicals. miRNA-mRNA prediction indicated that pre-mRNA processing factor 3 (PRPF3) is a likely target mRNA for miR-375 whose expression is altered by DEHP exposure. However, the interrelation between miR-375 and PRPF3 has not yet been confirmed experimentally. This study aimed to investigate the effects of DEHP on miR-375 and PRPF3 in zebrafish. The expression of miR-375 was downregulated, whereas PRPF3 was upregulated at both transcriptional and post-transcriptional levels upon stimulation with DEHP. The interaction between miR-375 and the 3'-untranslated region (3'-UTR) of PRPF3 was confirmed by a dual fluorescent protein assay and a dual luciferase reporter gene assay. The expression of PRPF3 at both transcriptional and post-transcriptional levels was reduced in ZF4 cells when transfected with a miR-375 mimic but increased when transfected with a miR-375 inhibitor. The results improved our understanding of molecular mechanisms of toxicity upon DEHP exposure and presented miR-375 as a potential novel toxicological biomarker for chemical exposure.

Abstract
Di (2-ethylhexyl) phthalate (DEHP) is often used as a plasticizer for plastic products, and its excessive use can cause irreversible damage to aquatic animals and humans. Evodiamine (EVO) is an alkaloid component in the fruit of Evodia rutaecarpa, which has antioxidant and detoxification functions. To investigate the toxic mechanism of DEHP on grass carp (Ctenopharyngodon idellus) hepatocyte cell line (L8824) and the therapeutic effect of evodiamine, an experimental model of L8824 cells exposed to 800 μM DEHP and/or 10 μM EVO for 24 h was established. Flow cytometry, AO/EB fluorescence staining, real-time quantitative PCR, and western blot were used to detect the degree of cell injury, oxidative stress level, MAPK signaling pathway relative genes, and the expression of apoptosis-related molecules. The results showed that DEHP exposure could significantly increase the level of reactive oxygen species (ROS), inhibit the activities of antioxidant enzymes (CAT, SOD, GSH-Px), and cause the accumulation of MDA. DEHP also activated MAPK signaling pathway-related molecules (JNK, ERK, P38 MAPK), and then up-regulated the expression of pro-apoptotic factors Bcl-2-Associated X (Bax) and caspase 3, while inhibiting the anti-apoptotic factor B-cell lymphoma-2 (Bcl-2). In addition, EVO can also promote the dissociation of nuclear factor-E2-related factor 2 (Nrf2) into the nucleus, reduce the level of ROS and the occurrence of oxidative stress in grass carp hepatocytes, down-regulate the MAPK pathway, alleviate DEHP-induced apoptosis, and restore the expression of antioxidant genes. These results indicated that evodiamine could block Nrf2/MAPK pathway to inhibit DEHP-induced apoptosis of grass carp hepatocytes.

Abstract
Hepatocellular carcinoma (HCC) or hepatoma is malignant cancer that starts from the main liver cells. Although various classical methods have been used for patients with HCC, various molecular mechanisms involved in HCC progression should be invested. Previous studies demonstrated that abnormal expression of long non-coding RNAs (lncRNAs) presented important roles in the pathogenesis of HCC cells. LncRNA TUG1 was found to mediate HCC cell growth, EMT, and metastasis. Therefore, targeting TUG1 and its downstream genes may be a suitable approach for patients with HCC. In this review, we summarized the potential roles of TUG1 in HCC.

MicroRNA-138-1-3p sensitizes sorafenib to hepatocellular carcinoma by targeting PAK5 mediated β-catenin/ABCB1 signaling pathway. J Biomed Sci 2021; 28:56. [PMID: 34340705 PMCID: PMC8327419 DOI: 10.1186/s12929-021-00752-4] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2021] [Accepted: 07/20/2021] [Indexed: 12/19/2022] Open
Abstract
Background Sorafenib is a kinase inhibitor that is used as a first-line therapy in advanced hepatocellular carcinoma (HCC) patients. However, the existence of sorafenib resistance has limited its therapeutic effect. Through RNA sequencing, we demonstrated that miR-138-1-3p was downregulated in sorafenib resistant HCC cell lines. This study aimed to investigate the role of miR-138-1-3p in sorafenib resistance of HCC. Methods In this study, quantitative real-time PCR (qPCR) and Western Blot were utilized to detect the levels of PAK5 in sorafenib-resistant HCC cells and parental cells. The biological functions of miR-138-1-3p and PAK5 in sorafenib-resistant cells and their parental cells were explored by cell viability assays and flow cytometric analyses. The mechanisms for the involvement of PAK5 were examined via co-immunoprecipitation (co-IP), immunofluorescence, dual luciferase reporter assay and chromatin immunoprecipitation (ChIP). The effects of miR-138-1-3p and PAK5 on HCC sorafenib resistant characteristics were investigated by a xenotransplantation model. Results We detected significant down-regulation of miR-138-1-3p and up-regulation of PAK5 in sorafenib-resistance HCC cell lines. Mechanistic studies revealed that miR-138-1-3p reduced the protein expression of PAK5 by directly targeting the 3′-UTR of PAK5 mRNA. In addition, we verified that PAK5 enhanced the phosphorylation and nuclear translocation of β-catenin that increased the transcriptional activity of a multidrug resistance protein ABCB1. Conclusions PAK5 contributed to the sorafenib resistant characteristics of HCC via β-catenin/ABCB1 signaling pathway. Our findings identified the correlation between miR-138-1-3p and PAK5 and the molecular mechanisms of PAK5-mediated sorafenib resistance in HCC, which provided a potential therapeutic target in advanced HCC patients.
