The intricate involvement of tryptophan degradation via KP serves as a critical regulator in mediating immunosuppression in the tumor microenvironment. The key enzymes that facilitate this mechanism and contribute to tumor progression are indoleamine 2,3-dioxygenase (IDO1) and tryptophan 2,3-dioxygenase (TDO). Despite attempts to use navoximod as a dual-specific inhibitor, its poor bioavailability and lack of clinical efficacy have hampered its utility. To date, no FDA-approved drugs have advanced for dual targeting of these enzymes. Therefore, this study aimed to repurpose the approved drugs from the DrugBank database as novel IDO1/TDO inhibitors. Initially, 2588 FDA-approved compounds were screened by employing molecular docking and pharmacokinetic profiling. Subsequently, methods such as MM-GBSA calculations and machine learning based analysis precisely identified 20 potential lead compounds. The resultant compounds were then assessed for various toxicity endpoints and anticancer activity. The PaccMann server revealed potent anticancer activity, with sensitivities ranging from 0.203 to 24.119 μM against MDA-MB-231 TNBC cell lines. Alongside, the interaction profile with critical residues, strongly reinforced DB06292 (Dapagliflozin) as a compelling hit candidate. Finally, the reliability of the result was corroborated through a rigorous 200 ns molecular dynamics simulation, ensuring the stable binding of the hit against the target proteins. Considering the promising outcomes, we speculate that the proposed hit compound holds strong potential for the management of TNBC.</p>","PeriodicalId":510,"journal":{"name":"Cell Biochemistry and Biophysics","volume":" ","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143707836","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}

Mice were then intraperitoneal administered IgG control, anti-Ly6G antibody and recombinant mouse NGAL at 1 h after the surgery and once daily from day 1-14 after surgery. At days 1, 3, 7, and 14 after surgery, echocardiogram showed that neutrophils significantly attenuates LV remodeling and reserves contractile function after MI compared with isotype control group. Flow cytometry revealed that the myocardial infiltration of macrophages decreased in MI mice with Ly6G-depleted. Moreover, WB and flow cytometry showed that macrophages differentiated by exposure to CM and NGAL, especially the latter, displayed a M2-like phenotype, expressing higher MerTK level than control M0 macrophages and the cells exposed to MPO. Meanwhile, flow cytometry indicated that the ability to remove dead cells of M2c-like macrophages triggered by NGAL significantly enhanced compared to those control M0 macrophages and the cells exposed to MPO. Most importantly, we validated that the decrease of M2c macrophage polarization in MI caused by neutrophils depletion can be reversed by NGAL in vivo. NGAL successfully induced the polarization of macrophages into M2c type.

Sonodynamic therapy (SDT) is a promising, non-invasive approach that utilizes ultrasound-activated sensitizers to induce cancer cell death. However, the role of ultrasound cavitation in enhancing SDT efficacy and its effects on mitochondrial stress responses remain unclear. We hypothesized that increasing cavitation density through optimized ultrasound parameters would enhance Ce6-mediated SDT effectiveness by increasing cytotoxicity, reactive oxygen species (ROS) generation, mitochondrial membrane potential (MMP) loss, and disrupting the mitochondrial unfolded protein response (mtUPR). Prostate cancer cells were treated with Ce6 and exposed to ultrasound with varying duty cycles (50% and 100%) and power intensities (0.5 W/cm², 1 W/cm², and 1.5 W/cm²). Cavitation density was measured, and its effects on cell viability, ROS levels, MMP disruption, and mtUPR mediator expression, including activating transcription factor 5 (ATF5), heat shock protein 60 (HSP60), and caseinolytic protease proteolytic subunit (CLPP), were analyzed at protein and mRNA levels. Higher duty cycles significantly increased cavitation density, leading to enhanced cytotoxicity, elevated ROS generation, and greater MMP loss in Ce6-mediated SDT. Additionally, SDT reduced mtUPR mediator expression, with cavitation further amplifying these effects. These findings suggest that cavitation-enhanced SDT may contribute to improved therapeutic efficacy in prostate cancer treatment by modulating mitochondrial stress responses and affecting cell viability. Optimizing ultrasound parameters to maximize cavitation effects may contribute to the development of more effective SDT-based cancer therapies.</p>","PeriodicalId":510,"journal":{"name":"Cell Biochemistry and Biophysics","volume":" ","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143707842","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}

In vivo, ISO treatment at 5, 10, and 15 mg/kg reduced the tumorigenic activity of MDA-MB-231 cells and decreased the levels of Ki-67 and CD31.

Despite global efforts, eradicating malaria has proven difficult, mainly because of the rise in drug resistance, particularly against artemisinin and its derivatives. One possible cause of this resistance is the activation of the unfolded protein response (UPR), which helps maintain cellular balance under stress. In P. falciparum, the UPR operates through the ubiquitin-proteasome system (UPS), which involves proteins such as Dsk2, Rad23, and Ddi1. Among these, Plasmodium falciparum DNA-damage-inducible protein 1 (PfDdi1) plays a crucial role in DNA repair and is present throughout the parasite life cycle, making it an attractive drug target. However, there is limited research on PfDdi1 as a therapeutic target. Recent in vitro studies have indicated that artemisinin (ART) and dihydroartemisinin (DHA) inhibit PfDdi1 activity. Building on this, we investigated whether ART and its derivatives could serve as inhibitors of PfDdi1 using computational modeling. Our study included clinically relevant ART derivatives such as artemether (ARM), arteether (AET), artemiside (AMD), and artesunate (ATS). All these compounds showed strong binding to PfDdi1, with free binding energies ranging from -20.75 kcal/mol for AET to -34.24 kcal/mol for ATS. ARM increased PfDdi1's structural rigidity and hydrophobic stability, whereas AMD improved its kinetic stability, resulting in the least residue motion. Unlike AET and AMD, the other ligands destabilize the PfDdi1 structure. Importantly, three key binding regions-Loop 1 (GLN 266 - ILE 269), Loop 2 (ILE 323 - TYR 326), and Loop 3 (ALA 292 - GLY 294)-were identified as potential targets for new antimalarial drugs against PfDdi1.
