Cell Stress Chaperones 2024; 29:697-708. [PMID: 39370036 PMCID: PMC11526090 DOI: 10.1016/j.cstres.2024.10.001] [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: 07/14/2024] [Revised: 09/30/2024] [Accepted: 10/01/2024] [Indexed: 10/08/2024] Open
Abstract
Ebeiedinone and peimisine are the major active ingredients of Fritillariae Cirrhosae Bulbus. In this study, we looked at how these two forms of isosteroidal alkaloids protect human bronchial epithelial BEAS-2B cells from oxidative stress and apoptosis caused by cigarette smoke extract (CSE). First, the cytotoxicity was determined using the CCK8 assay, and an oxidative stress model was established. Then the antioxidative stress activity and mechanism were investigated by ELISA, flow cytometry, and Western blotting. By the CCK-8 assay, exposure to CSE (20%, 40%, and 100%) reduced the viability of BEAB-2S cells. The flow cytometry findings indicated that CSE-induced production of ROS (0.5% to maximum) and treatments with 10 μM ebeiedinone and 20 μM peimisine attenuated the production of ROS. The western blot assay results indicate that ebeiedinone and peimisine reduce CSE-induced oxidative stress, DNA damage, apoptosis, and autophagy dysregulation by inhibiting ROS, upregulating SOD and GSH/GSSG, and downregulating MDA, 4-HNE, and 8-OHdG through the NRF2/KEAP1 and JNK/MAPK-dependent pathways, thereby delaying the pathological progression of COPD caused by CS.Our data suggest that CSE causes oxidative stress, DNA damage, and apoptosis in BEAS-2B cells, as well as the progression of COPD. Ebeiedinone and peimisine fight CS-induced COPD by suppressing autophagy deregulation and apoptosis.

Han B, Chen J, Chen S, Shen X, Hou L, Fang J, Lian M. PPARG and the PTEN-PI3K/AKT Signaling Axis May Cofunction in Promoting Chemosensitivity in Hypopharyngeal Squamous Cell Carcinoma. PPAR Res 2024; 2024:2271214. [PMID: 38505269 PMCID: PMC10948231 DOI: 10.1155/2024/2271214] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2023] [Revised: 01/23/2024] [Accepted: 01/29/2024] [Indexed: 03/21/2024] Open
Abstract
It has been demonstrated that PPARG may interact with the PTEN-PI3K/AKT pathway, contributing to its involvement in the chemotherapy treatment of hypopharyngeal squamous cell carcinoma (HSCC). However, the underlying mechanism remains largely unknown. In this study, gene expression profiles of 17 HSCC patients, comprising 8 chemotherapy-sensitive patients (CSP) and 9 chemotherapy-nonsensitive patients (CNSP), were collected and analyzed to investigate expression patterns, correlations, influencing factors of the PPARG-PTEN-PI3K/AKT pathway, and its role in regulating chemosensitivity. The results revealed significantly increased expression (p < 0.04) of AKT1, AKT2, AKT3, PIK3CA, PPARG, and PTEN in the CSP group compared to the CNSP group. Specifically, AKT2 exhibited significant overexpression in tumor tissue (p = 0.01), while AKT2, AKT3, PPARG, and PTEN displayed significant increases in normal tissue (p ≤ 0.04). Positive correlations (R ∈ [0.43, 0.71], p < 0.014) were observed between PIK3CA, AKT1, AKT2, AKT3, and PTEN, with AKT2, AKT3, and PTEN also showing significant correlations with PPARG (R ∈ [0.35, 0.47], p < 0.04). Age, gender, and disease stage had no influence on PPARG, PIK3CA, and PTEN expression, but they may affect AKT expressions. Pathway analysis revealed that PPARG may interact with the PTEN-PI3K/AKT signaling pathway, playing a crucial role in regulating chemosensitivity in the normal tissue microenvironment. Our results suggest that AKT1 and PIK3CA may be associated with chemosensitivity in HSCC tumor cells, while PPARG and PTEN might exhibit a correlation with a specific segment of the PI3K/AKT pathway, potentially influencing chemosensitivity in the normal tissue microenvironment of HSCC patients.

An integrated strategy of UPLC-Q-TOF-MS analysis, network pharmacology, and molecular docking to explore the chemical constituents and mechanism of Zixue Powder against febrile seizures. Heliyon 2024; 10:e23865. [PMID: 38192830 PMCID: PMC10772254 DOI: 10.1016/j.heliyon.2023.e23865] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2023] [Revised: 12/14/2023] [Accepted: 12/14/2023] [Indexed: 01/10/2024] Open
Abstract
Febrile seizures (FS) are the most common type of seizures for children. As a commonly used representative cold formula for resuscitation, Zixue Powder (ZP) has shown great efficacy for the treatment of FS in clinic, while its active ingredients and underlying mechanism remain largely unclear. This study aimed to preliminarily elucidate the material basis of ZP and the potential mechanism for the treatment of FS through ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS), network pharmacology, and molecular docking. UPLC-Q-TOF-MS was firstly applied to characterize the ingredients in ZP, followed by network pharmacology to explore the potential bioactive ingredients and pathways of ZP against FS. Furthermore, molecular docking technique was employed to verify the binding affinity between the screened active ingredients and targets. As a result, 75 ingredients were identified, containing flavonoids, chromogenic ketones, triterpenes and their saponins, organic acids, etc. Through the current study, we focused on 13 potential active ingredients and 14 key potential anti-FS targets of ZP, such as IL6, STAT3, TNF, and MMP9. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analysis showed that inflammatory response, EGFR tyrosine kinase inhibitor resistance, AGE-RAGE signaling pathway in diabetic complications, and neuroactive ligand-receptor interaction were the main anti-FS signaling pathways. Licochalcones A and B, 26-deoxycimicifugoside, and hederagenin were screened as the main potential active ingredients by molecular docking. In conclusion, this study provides an effective in-depth investigation of the chemical composition, potential bioactive components, and possible anti-FS mechanism of ZP, which lays the foundation for pharmacodynamic studies and clinical applications of ZP.
