Previous studies indicated that exosomes derived from CAFs might transmit regulating signals and boost esophageal squamous cell carcinoma (ESCC) development. This study is designed to explore the role and mechanism of CAFs-derived exosomal microRNA-889-3p (miR-889-3p) in ESCC progression. Macrophage polarization was detected using flow cytometry. miR-889-3p, Tumor necrosis factor alpha (TNF-α), and inducible nitric oxide synthase (iNOS) levels were detected by real-time quantitative polymerase chain reaction (RT-qPCR). Cell proliferation, cycle progression, migration, and invasion were assessed using Cell Counting Kit-8 (CCK-8), 5-ethynyl-2'-deoxyuridine (EdU), scratch assay, and Transwell assays. α-SMA, FAP, CD63, CD81, and signal transducer and activator of transcription 1 (STAT1) protein levels were detected using western blot. Exosomes were characterized using an electron microscope and nanoparticle tracking analysis (NTA). Binding between miR-889-3p and STAT1 was predicted by Starbase, and verified by a dual-luciferase reporter and RNA pull-down. The effect of CAFs-derived exosomal miR-889-3p on ESCC tumor growth in vivo was detected using mice xenograft assay. miR-889-3p level was decreased in LPS-induced M0 macrophages. CAF-derived exosomal miR-889-3p knockdown suppressed ESCC proliferation, migration, and invasion. CAFs might transfer miR-889-3p to M0 macrophages via exosomes. STAT1 was a target of miR-889-3p. Besides, in vivo studies confirmed that CAFs-derived exosomal miR-889-3p can accelerate ESCC tumor growth by regulating STAT1. CAFs-derived exosomal miR-889-3p facilitates esophageal squamous cell carcinoma cell proliferation, migration, and invasion by inhibiting M1 macrophage polarization through down-regulation of STAT1, providing a promising therapeutic target for ESCC.</p>","PeriodicalId":510,"journal":{"name":"Cell Biochemistry and Biophysics","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2024-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142138931","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Drug-likeness predictions were assessed using SwissADME v2023 and Pass online v2.0. Molecular dynamics (MD) simulations identified promising compounds, focusing on stability and interaction dynamics. Beta-Glucogallin (BEG) and Dihydro Dehydro Coniferyl alcohol (DIH) emerged as significant hits. MD simulations with GROMACS v2020.6 revealed stable BEG and DIH complexes with AgrC, forming six hydrogen bonds with six key amino acids (Arg-303, Asp-338, Glu-342, Glu-384, Lys-389, Gly-396), indicating strong and stable bonding. The binding affinities for DIH and BEG are -73.474 ± 11.104 kJ/mol and -6.319 ± 18.823 kJ/mol with 4BXI, respectively. Our findings highlight BEG and DIH as promising candidates against AMR S. aureus infections, showing favourable binding affinities and stable interactions with AgrC.

Drugs targeting phosphodiesterase 5 (PDE5) inhibition, such as sildenafil, have been employed to treat erectile dysfunction (EDRF), but they are associated with several complications. This study investigated the effect of C. populnea extracts (aqueous and saponin-rich) on the activity and gene expressions of proteins related to erection. PDE5, Nitric oxide synthase (NOS) and androgen receptor (AR) genes were studied using RT-PCR on CP-treated paroxetine-induced ERDF-rats. It also employed Schrödinger suites for investigations such as molecular and induced-fit docking, MMGBSA, ADMET, and QSAR profiling of CP-phytocompounds. C. populnea extracts reduce the activity and downregulate the expression of the PDE5 gene while upregulating the expressions of AR and NOS genes in the ERDF-rats relative to the control group. Five (leading) compounds with induced-fit docking (IFD) scores in kcal/mol, namely, stigmasterol (-638.73), daucosterol (-644.73), furostanol (-639.29), papaverine (-639.03), and capsaicin (-642.88), had better docking scores of -9.936, -9.824, -9.064, -8.863, and -8.736 kcal/mol, respectively, compared with those of sildenafil (-8.611 kcal/mol).

The underlying pathophysiology of SE involves systemic inflammation, neuroinflammation, blood-brain barrier (BBB) disruption, and mitochondrial dysfunction. Among these factors, mitochondrial dysfunction plays a pivotal role, contributing to impaired ATP production, increased reactive oxygen species (ROS) generation, and activation of apoptotic pathways, all of which exacerbate neuronal damage and cognitive deficits. Diagnosis of SE relies on clinical evaluation, neuroimaging, electroencephalography (EEG), and laboratory tests, though specific diagnostic markers are still lacking. Epidemiological data show SE is prevalent in intensive care unit (ICU) patients, especially those with severe sepsis or septic shock, with incidence rates varying widely depending on the population and diagnostic criteria used. Recent research highlights the importance of mitochondrial dynamics, including biogenesis, fission, and fusion, in the development of SE. Mitophagy, a selective form of autophagy that degrades damaged mitochondria, plays a critical role in maintaining mitochondrial health and protecting against dysfunction. Targeting mitochondrial pathways and enhancing mitophagy offers a promising therapeutic strategy to mitigate the effects of SE, reduce oxidative stress, prevent apoptosis, and support the resolution of neuroinflammation.
