THE SCIENCE OF THE TOTAL ENVIRONMENT 2024; 927:172381. [PMID: 38604374 DOI: 10.1016/j.scitotenv.2024.172381] [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: 11/09/2023] [Revised: 03/12/2024] [Accepted: 04/08/2024] [Indexed: 04/13/2024]
Abstract
BACKGROUND In fisheries, hypoxia stress is one of the most common environmental stresses that often lead to the death of large numbers of fish and cause significant economic losses. The pituitary, an important endocrine gland, lies below the hypothalamus region of the brain. It plays a crucial part in controlling vital physiological functions in fish, such as growth, reproduction, and responses to stress. However, the detailed mechanisms of how hypoxia affects these physiological processes via the pituitary remain largely unknown. METHODS Fat greenlings (Hexagrammous otakii) were exposed to different dissolved oxygen (DO = 7. 6 mg/L and DO = 2 mg/L) for 24 h. miRNA-mRNA association analysis of H. otakii pituitary after hypoxia stress. Detecting apoptosis in H. otakii pituitary using Tunel and qPCR. Subsequent detection of hormones in H. otakii liver, gonads and serum by ELISA. RESULTS In this study, hypoxia causes immune system disorders and inflammatory responses through the combined analysis of miRNAs and mRNAs. Subsequent verification indicated a significant accumulation of reactive oxygen species (ROS) subsequent to hypoxia treatment. The overproduction of ROS cause oxidative stress and apoptosis in the pituitary, ultimately causing pituitary damage and reduced growth hormone and luteinising hormone release. CONCLUSIONS According to the association study of miRNA-mRNA, apoptosis problems caused by hypoxia stress result in H. otakii pituitary damage. In the meantime, this work clarifies the possible impact of hypoxia-stress on the pituitary cells, as well as on the gonadal development and growth of H. otakii.

[PMID: 36563885 DOI: 10.1016/j.bcp.2022.115388] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2022] [Revised: 12/14/2022] [Accepted: 12/15/2022] [Indexed: 12/24/2022]
Abstract
The cardiotoxicity of trastuzumab (TRZ) seriously affects the prognosis of breast cancer patients, but the underlying mechanisms remains to be elucidated. This study aimed to investigate the potential molecular mechanisms of TRZ-induced cardiotoxicity based on RNA sequencing (RNA-Seq) and bioinformatics analysis. Kunming mice were exposed to 10 mg/kg TRZ for 6 and 10 days, followed by echocardiography, histopathology and serum biochemical analysis to evaluate the cardiotoxicity model. The results showed no significant changes after 6 days administration of TRZ. After 10 days administration of TRZ, the mice showed cardiac dysfunction, myocardial injury and fibrosis, and the serum levels of LDH, CK, CK-MB and cTnI were increased compared to the control [CON (Day 10)] group, indicating the cardiotoxicity model was successfully established. We compared gene expression levels in mice cardiac tissues by RNA-Seq and screened out 593 differentially expressed genes (DEGs). Results based on Gene Ontology (GO) analysis, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis, protein-protein interaction (PPI) network analysis and RT-PCR revealed that the CD74/STAT1 signaling pathway might play an important role in TRZ-induced cardiotoxicity. In the TRZ group, the protein expressions of CD74, p-STAT1 (Tyr) and p-STAT1 (Ser) were increased. The TUNEL staining showed increased apoptosis of cardiomyocytes. In addition, an increased expressions of Bax, Caspase-3, IFN-γ and TNF-α and a decreased expression of Bcl-2 were observed in Western blot results, indicating the apoptosis and inflammation levels were increased. These findings suggested that TRZ may induce cardiotoxicity in mice by activating the CD74/STAT1 signaling pathway, which might be related to the induction of apoptosis and inflammation.

Abstract
Astragali Radix is a significant traditional Chinese medication, and has a long history of clinical application in the treatment of diabetes mellitus (DM) and its complications. AS-IV is an active saponin isolated from it. Modern pharmacological study shows that AS-IV has anti-inflammatory, anti-oxidant and immunomodulatory activities. The popular inflammatory etiology of diabetes suggests that DM is a natural immune and low-grade inflammatory disease. Pharmacological intervention of the inflammatory response may provide promising and alternative approaches for the prevention and treatment of DM and its complications. Therefore, this article focuses on the potential of AS-IV in the treatment of DM from the perspective of an anti-inflammatory molecular basis. AS-IV plays a role by regulating a variety of anti-inflammatory pathways in multiple organs, tissues and target cells throughout the body. The blockade of the NF-κB inflammatory signaling pathway may be the central link of AS-IV's anti-inflammatory effect, resulting in a reduction in the tissue structure and function damage stimulated by inflammatory factors. In addition, AS-IV can delay the onset of DM and its complications by inhibiting inflammation-related oxidative stress, fibrosis and apoptosis signals. In conclusion, AS-IV has therapeutic prospects from the perspective of reducing the inflammation of DM and its complications. An in-depth study on the anti-inflammatory mechanism of AS-IV is of great significance for the effective use of Chinese herbal medicine and the promotion of its status and influence on the world.
