Funct Integr Genomics 2025; 25:95. [PMID: 40289171 DOI: 10.1007/s10142-025-01591-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2024] [Revised: 02/28/2025] [Accepted: 03/22/2025] [Indexed: 04/30/2025]
Abstract
OBJECTIVE To investigate the mechanisms by which the RNA-binding protein HuR /ELAVL1 interacts with UFM1 mRNA to ameliorate chondrocyte inflammation, apoptosis, and extracellular matrix (ECM) degradation in osteoarthritis (OA). METHODS OA cartilage tissues were collected. A lipopolysaccharide-induced chondrocyte inflammation model was constructed and transfected with relevant sequences or plasmids, chondrocyte viability was detected by MTT, and chondrocyte apoptosis was detected by flow cytometry. OA was induced in rats via anterior cruciate ligament transection (ACLT), and lentiviral vectors mediating overexpression or silencing of HuR/UFM1 were administered via intra-articular injection following surgery. The pathology of cartilage tissue in rats was observed by hematoxylin and eosin staining and safranin O/fast green staining, apoptosis was detected by terminal deoxynucleotidyl transferase dUTP nick-end labeling (TUNEL) staining, and Collagen II, Aggrecan, MMP3, and MMP13 were measured by immunohistochemistry. Western blot was conducted to measure PCNA, Cleaved-caspase 3, Collagen II, Aggrecan, MMP3 and MMP13. Inflammatory factors in chondrocyte supernatant and rat serum were detected using an enzyme-linked immunosorbent assay. HuR and UFM1 detection was performed using real-time fluorescence quantitative PCR and Western blot. Bioinformatics software, RIP, RNA pull down and mRNA stability analysis were combined to study the binding relationship between HuR and UFM1. RESULTS HuR expression was down-regulated in OA. HuR overexpression ameliorated OA chondrocyte inflammation, apoptosis, and ECM degradation, and HuR downregulation aggravated these pathologies. HuR regulated UFM1 stability by binding to UFM1 3'UTR. UFM1 expression was downregulated in OA and positively correlated with HuR expression. UFM1 silencing counteracted the ameliorative effect of HuR on OA chondrocyte inflammation, apoptosis, and ECM degradation. CONCLUSION HuR ameliorates OA chondrocyte inflammation, apoptosis, and ECM degradation through post-transcriptional regulation of UFM1.

Song R, Jiang Y, Zhang B, Jiao Z, Yang X, Zhang N. Effects of Hypericum attenuatum Choisy extract on the immunologic function and intestinal microflora of broilers under oxidative stress. Poult Sci 2024; 103:104189. [PMID: 39191003 PMCID: PMC11395763 DOI: 10.1016/j.psj.2024.104189] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2024] [Revised: 07/19/2024] [Accepted: 08/03/2024] [Indexed: 08/29/2024] Open
Abstract
This study investigated the impact of Hypericum attenuatum Choisy extract (HYG) on immunological function and the cecum microflora in broilers. A total of 240 one-day-old AA broilers were randomly divided into 5 groups with 6 replicates of 8 broilers each: 1) the CN group, in which broilers were injected with saline and fed a basal diet; 2) the PC group, in which broilers were injected with lipolyaccharide (LPS) and fed a basal diet; 3) the HYG1 group, in which broilers were injected with LPS and fed a 400 mg/kg HYG-supplemented diet; 4) the HYG2 group, in which broilers were injected with LPS and fed a 800 mg/kg HYG-supplemented diet; 5) the HYG3 group, in which broilers were injected with LPS and fed a 1,200 mg/kg HYG-supplemented diet. Broilers were injected with 1 mg/kg LPS or the same amount saline 12 hours before sampling on d 21 and 42. The results revealed that dietary 400 mg/kg HYG supplementation alleviated spleen index and thymus index abnormalities, balanced the disturbance of serum immunoglobulin (Ig)M and IgA levels, and regulated the cytokine balance in the serum, liver, spleen and jejunum tissues included induced by LPS. Dietary supplementation with 400 mg/kg HYG also downregulated the relative expression of the inhibitor of kappa B kinase alpha (IKKα) and interleukin (IL)-6 mRNAs in the liver and upregulated the relative expression of the inhibitor kappa B alpha (IκBα) and IL-10 mRNAs in the spleen. Dietary HYG improved the cecal microflora balance at 42 d by increasing the relative abundance of beneficial bacteria, such as Alistipes and Phascolarctobacterium, while reducing the relative abundance of harmful bacteria, such as Helicobacter and Colidextribacter. Spearman correlation analysis revealed a negative correlation between activation of the NF-κB inhibitory pathway in the liver and the presence of Phascolarctobacterium, Erysipelatoclostridium, Subdoligranulum and Parabacteroides. Conclusions: The incorporation of 400 mg/kg HYG into the diet was optimal in improving broiler immunological function.

Abstract
Post-translational modification is a rite of passage for cellular functional proteins and ultimately regulate almost all aspects of life. Ubiquitin-fold modifier 1 (UFM1) system represents a newly identified ubiquitin-like modification system with indispensable biological functions, and the underlying biological mechanisms remain largely undiscovered. The field has recently experienced a rapid growth of research revealing that UFMylation directly or indirectly regulates multiple immune processes. Here, we summarised important advances that how UFMylation system responds to intrinsic and extrinsic stresses under certain physiological or pathological conditions and safeguards immune homeostasis, providing novel perspectives into the regulatory framework and functions of UFMylation system, and its therapeutic applications in human diseases.

Vieira RR, da Silva RA, Sasso GRS, Franco PC, Borges FT, Lima PDA, Sanches JM, Gil CD, Carbonel AAF. Lack of Annexin A1 Exacerbates Inflammatory Response in Acute Endometritis Model. Inflammation 2024; 47:1041-1052. [PMID: 38198110 DOI: 10.1007/s10753-023-01959-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Revised: 12/22/2023] [Accepted: 12/25/2023] [Indexed: 01/11/2024]
Abstract
Annexin A1 (AnxA1) is a glucocorticoid-inducible protein and an important endogenous modulator of inflammation. However, its effect in the endometrial microenvironment is poorly explained. This study aimed to evaluate the role of endogenous AnxA1 in an endometritis mouse model induced by lipopolysaccharide (LPS). Female C57BL/6 wild-type (WT) and AnxA1-/- mice were divided into two groups: SHAM and LPS. To induce endometritis, mice received a vaginal infusion of 50 μL of LPS (1 mg/mL) dissolved in phosphate-buffered saline. After 24 h, the mice were euthanized, and blood and uteri samples were collected. The endometrium inflammatory scores were significantly increased in the LPS-treated group. AnxA1-/- mice from the LPS group demonstrated a significant increase in the number of degranulated mast cell levels compared to AnxA1-/- SHAM mice. The Western blotting analysis revealed that a lack of AnxA1 promoted the upregulation of NLRP3 and pro-IL-1β in the acute endometritis animal model compared to WT LPS animals. LPS-induced endometritis increased the number of blood peripheral leukocytes in both WT and AnxA1-/- mice compared with SHAM group mice (p < 0.001). AnxA1-/- mice also showed increased plasma levels of IL-1β (p < 0.01), IL-6, IL-10, IL-17, and TNF-α (p < 0.05) following LPS-induced endometritis. In conclusion, a lack of endogenous AnxA1 exacerbated the inflammatory response in an endometritis model via NLRP3 dysregulation, increased uterine mast cell activation, and plasma pro-inflammatory cytokine release.

Downregulation of XBP1s aggravates lipopolysaccharide-induced inflammation by promoting NF-κB and NLRP3 pathways' activation in goat endometrial epithelial cells. Theriogenology 2023; 210:119-132. [PMID: 37494784 DOI: 10.1016/j.theriogenology.2023.07.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2022] [Revised: 12/16/2022] [Accepted: 07/13/2023] [Indexed: 07/28/2023]
Abstract
After delivery, bacterial contamination and uterine tissue degeneration in animals can lead to the development of uterine diseases, such as endometritis, accompanied by endoplasmic reticulum stress (ERS). Increasing evidence suggests that spliced X-box binding protein 1 (XBP1s), a critical component of ERS, is involved in several pathological processes in various organisms. However, the specific molecular mechanisms by which XBP1s mediates the inflammatory response in goat endometrial epithelial cells (gEECs) remain largely unknown. In the present study, XBP1s protein was induced into the nucleus in the lipopolysaccharide (LPS, 5 μg/mL)-induced inflammatory response of gEECs. Lipopolysaccharide-induced expression and nucleation of XBP1s were reduced by the inhibition of Toll-like receptor 4 (TLR4) using TAK-242 (1 μM; a TLR4 inhibitor). Expression and nucleation of XBP1s were similarly reduced when the activity of inositol-requiring enzyme 1α (IRE1α) was inhibited using 4μ8C (10 μM; an IRE1α inhibitor). In addition, inhibition of IRE1a increased IL-1β, TNF-α, and IL-8 levels and secretion of IL-6 induced by LPS. Notably, phosphorylation of nuclear factor kappa-B (NF-κB) P65 protein and expression of NOD-like receptor thermal protein domain associated protein 3 (NLRP3) were similarly increased. Furthermore, knockdown of XBP1s in gEECs consistently promoted NF-κB P65 protein phosphorylation, NLRP3 protein expression, and inflammatory cytokine secretion. In summary, the current results suggest that in the LPS-induced inflammatory response in gEECs, LPS generates intracellular signaling cascades in gEECs via TLR4, which may promote XBP1s protein expression and nucleation by activating IRE1a. However, downregulation of XBP1s expression exacerbates inflammation by promoting activation of the NF-κB and NLRP3 inflammatory vesicle pathways. These results will potentially contribute to the treatment and prevention of endometritis in ruminants.

Abstract
The NLR family pyrin domain containing 3 (NLRP3) inflammasome is involved in the innate immune system and is a three-part macromolecular complex comprising the NLRP3 protein, apoptosis-associated speck-like protein containing a CARD (ASC) and the cysteine protease pro-caspase-1. When the NLRP3 inflammasome is activated, it can produce interleukin (IL)- 1β and IL-18 and eventually lead to inflammatory cell pyroptosis. Related studies have demonstrated that the NLRP3 inflammasome can induce an immune response and is related to the occurrence and development of gynecological diseases, such as endometriosis, polycystic ovary syndrome and breast cancer. NLRP3 inflammasome inhibitors are beneficial for maintaining cellular homeostasis and tissue health and have been found effective in targeting some gynecological diseases. However, excessive inhibitor concentrations have been found to cause adverse effects. Therefore, proper control of NLRP3 inflammasome activity is critical. This paper summarizes the structure and function of the NLRP3 inflammasome and highlights the therapeutic potential of targeting it in gynecological diseases, such as endometriosis, polycystic ovary syndrome and breast cancer The application of NLRP3 inflammasome inhibitors is also discussed.
