Behavioral changes may be driven by changes in hormone secretion in animals. When animals face with noise stress, the neuroendocrine systems, mainly the hypothalamic-pituitary-adrenal (HPA) axis, are activated, which promotes the secretion and release of stress hormones, and then leads to a series of behavioral changes. The behavioral changes can be easily observed, but the changes in physiological indicators such as hormone levels need to be accurately measured. Currently, many studies have measured the variations of stress hormone levels in animals under different noise conditions. Taking glucocorticoid as an example, this paper summarizes the different measurement methods of stress hormones, especially the non-invasive measurement methods, and compares the advantages and shortcomings of them. It provides a variety of measurement choices for the study of related issues, and also helps us to further understand the sources of animal stress, in order to provide a better habitat for animals.</p>","PeriodicalId":7134,"journal":{"name":"Acta physiologica Sinica","volume":"76 3","pages":"407-417"},"PeriodicalIF":0.0,"publicationDate":"2024-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141465467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, its involvement in depression and the underlying mechanisms remain poorly understood. This study aimed to investigate the effect of 6-formylindolo[3,2-b]carbazole (FICZ), an endogenous AhR ligand, on a lipopolysaccharide (LPS)-induced depression model and the underlying mechanism. After being treated with FICZ (50 mg/kg), male C57BL/6J mice received intraperitoneal injection of LPS and underwent behavioral tests 24 h later. The levels of inflammatory cytokines, including IL-1β, IL-6, and TNF-α, were measured in the hippocampus and serum using enzyme-linked immunosorbent assay (ELISA). The expression levels of CYP1A1, AhR and NLRP3 were analyzed using qPCR and Western blot. The results showed that, compared with control group, LPS alone significantly down-regulated the expression levels of CYP1A1 mRNA and AhR protein in the hippocampus of mice, reduced glucose preference, prolonged immobility time in forced swimming test, increased IL-6 and IL-1β levels in the hippocampus, increased serum IL-1β level, and up-regulated NLRP3 mRNA and protein expression levels in mouse hippocampus, while FICZ significantly reversed the aforementioned effects of LPS. These findings suggest that AhR activation attenuates the inflammatory response associated with depression and modulates the expression of NLRP3. The present study provides novel insights into the role of AhR in the development of depression, and presents AhR as a potential therapeutic target for the treatment of depression.</p>","PeriodicalId":7134,"journal":{"name":"Acta physiologica Sinica","volume":"76 3","pages":"353-364"},"PeriodicalIF":0.0,"publicationDate":"2024-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141465492","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to lack of effective pharmaceutic therapies, it is urgent to explore new prevention and treatment strategies.

SLPI can also assist the immune system to clear pathogens/damaged cells by enhancing the phagocytic function of phagocytes, so as to ameliorate tissue damage and promote repair. Moreover, recent studies have shown that the change of SLPI level in the serum of patients post cardiovascular surgery has a high diagnostic value in predicting the occurrence of acute kidney injury, suggesting that SLPI is involved in ischemia-reperfusion (IR) induced acute kidney injury.

Ten from 38 male Sprague-Dawley (SD) rats (3-month-old) were randomly selected into young (Y) group, while the rest were raised to 21 months old and randomly divided into elderly control (O), endurance exercise (EN) and resistance exercise (R) groups. After 8 weeks of corresponding exercises training, the gastrocnemius muscles of rats were collected, and the expression of S100B in Schwann cells was detected by immunofluorescence staining. Western blot was used to detect the protein expression levels of agglutinate protein (Agrin), low-density lipoprotein receptor-related protein 4 (Lrp4), muscle- specific kinase protein (MuSK), downstream tyrosine kinase 7 (Dok7), phosphorylated protein kinase B (p-Akt), phosphorylated mammalian target rapamycin (p-mTOR), and phosphorylated forkhead box O1 (p-FoxO1) in rat gastrocnemius muscles. The results showed that, endurance and resistance exercises increased the wet weight ratio of gastrocnemius muscle in the aging rats. The protein expression of S100B in the R group was significantly higher than those in the O and EN groups. Proteins related to NMJ function, including Agrin, Lrp4, MuSK, and Dok7 were significantly decreased in the O group compared with those in the Y group. Resistance exercise up-regulated these four proteins in the aging rats, whereas endurance exercise could not reverse the protein expression levels of Lrp4, MuSK and Dok7.

Thalassemia are classified into transfusion-dependent thalassemia and non-transfusion-dependent thalassemia based on the need for blood transfusion. Traditional treatment modalities include blood transfusion, splenectomy, hydroxyurea therapy, and iron chelation therapy, which are now widely used for clinical treatment and constitute the main methods recommended in the β-thalassemia treatment guidelines. However, there are multiple barriers and limitations to the application of these approaches, and there is an urgent need to explore new therapeutic approaches. With the in-depth study of the pathophysiological process of β-thalassemia, a deeper understanding of the pathogenesis of the disease has been gained. It has been demonstrated that the pathogenesis of thalassemia is closely related to ineffective erythropoiesis (IE), imbalance in the ratio of α/β-globin protein chains and iron overload. New therapeutic approaches are emerging for different pathogenic mechanisms. Among them, new drugs for the treatment of IE mainly include activin receptor II trap ligands, Janus kinase 2 inhibitors, pyruvate kinase activators, and glycine transporter protein 1 inhibitors. Correcting the imbalance in the hemoglobin chain is mainly due to emerging technologies such as bone marrow transplantation and gene editing. Measures in reducing iron overload are associated with inhibiting the activity of transferrin and hepcidin.
