This study explored whether NBP could protect neurons after spinal cord injury (SCI) by inhibiting excessive autophagy, and its intrinsic mechanism were investigated. In methodology, this paper detected the Hippo/YAP pathway activity and autophagy in peripheral blood of SCI patients. A SCI cell model and a rat SCI model were established. Through a series of assays and experimental validation, the effect and mechanism of NBP on neuronal damage after SCI were analyzed. As a result, the activated Hippo pathway, decreased YAP protein, and increased p-YAP, Beclin 1, and LC3 II/I proteins were monitored in peripheral blood of SCI patients. OGD treatment enhanced apoptosis and autophagy, activated the Hippo/YAP pathway, and enhanced YAP nuclear translocation in PC12 cells. NBP treatment eliminated these effects of OGD on PC12 cells. YAP silencing reversed the suppression of NBP on the OGD-induced PC12 cell apoptosis and autophagy. In vivo, the inhibition of NBP on neuronal injury, the Hippo/YAP pathway activity, and autophagy was abolished by YAP silencing. Thus, NBP attenuates autophagy to alleviate neuronal apoptosis after SCI via inactivating the Hippo/YAP pathway. NBP may be useful in SCI treatment clinically.</p>\u0000 </div>","PeriodicalId":143,"journal":{"name":"Chemical Biology & Drug Design","volume":"106 4","pages":""},"PeriodicalIF":3.3,"publicationDate":"2025-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145310312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The unique analgesic activity of KOR requires KOR activation that recruits downstream effectors. It is noted that KOR primarily couples to the G_i/o family proteins in the process of KOR signaling that contain the conventional (G_i1, G_i2, G_i3, G_oA, and G_oB) and nonconventional (G_z and G_g) subtypes. The molecular mechanisms governing KOR signaling—particularly its selectivity for G_i/o protein subtypes and the pathway specificity of its ligands—remain unclear. Furthermore, the structural and energetic sequence of events during the activation of KOR and its cognate G_i/o proteins is poorly understood. This lack of knowledge hinders the structure-based design of pharmacophores targeting the KOR/G_i/o complex. It suggests that further research and investigation are required to analyze the crystal structure of the agonists/KOR complexes and various intermediate states in the KOR activation pathway. Some improved enhanced sampling methods, such as umbrella sampling, metadynamics, and Markov State Model methods, can characterize the interaction between GPCRs and different G protein subtypes after specific ligands binding, and the free energy landscapes along the ligand binding pathway. In this review, we discuss the research advances in the molecular mechanisms of KOR signaling. We also present a brief overview of computational conformational sampling methods based on molecular dynamics, including the activation mechanisms, allosteric effects, and actions of biased ligands of GPCRs to describe their activation energy landscape. It can provide an insight into evaluate the convergence of free energy surfaces along coordinates of functional interest, which is helpful to understand the role of GPCR conformational ensembles in intracellular signal transduction.</p>\u0000 </div>","PeriodicalId":143,"journal":{"name":"Chemical Biology & Drug Design","volume":"106 4","pages":""},"PeriodicalIF":3.3,"publicationDate":"2025-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145294549","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the mechanisms underlying PLBG-induced anti-tumor activity in NSCLC remain incompletely understood. Our study demonstrated that PLBG significantly inhibited NSCLC cell proliferation and induced apoptosis by elevating intracellular and mitochondrial reactive oxygen species (ROS), leading to mitochondrial dysfunction. The ROS scavenger N-acetylcysteine (NAC) abrogated PLBG-induced apoptosis and restored cell viability. Notably, RNA sequencing analysis revealed that differentially expressed genes in PLBG-treated cells were enriched in the cytosolic DNA-sensing pathway and STING pathway. Mechanistically, PLBG treatment activated the STING pathway and upregulated key chemokines (CXCL10, CXCL9, CCL5) in NSCLC cells. Critically, STING inhibition by H151 attenuated PLBG-induced apoptosis, confirming the essential role of STING. These results suggest that PLBG exerts potent anti-NSCLC effects through ROS-mediated apoptosis, STING pathway activation, and chemokine induction, while concurrently inhibiting pro-survival signaling.

However, its mechanism of action in DR remains poorly understood. To explore this, we established an in vitro high glucose (HG) model using human retinal microvascular endothelial cells (hRMECs) and an in vivo diabetic rat model. Cells were cultured in normal glucose (NG, 5 mM) or HG (30 mM) for 48 h, followed by PRO treatment. Techniques including qRT-PCR, Western blotting, flow cytometry, histological staining, Transwell, tube formation, chromatin immunoprecipitation (ChIP), and dual-luciferase assays were employed. PRO treatment conferred protection against DR; however, this effect was reversed upon knockdown of activating transcription factor 1 (ATF1). Mechanistically, ATF1 enhanced transcription of synoviolin 1 (SYVN1), promoting HMGB1 degradation via ubiquitination and suppressing the HMGB1/toll-like receptor 4 (TLR4) signaling pathway. Findings from the in vitro model were validated in vivo. In conclusion, PRO alleviates DR by regulating the ATF1/SYVN1/HMGB1 axis and inhibiting pro-inflammatory signaling.
