Tislelizumab, a PD-1 inhibitor developed in China, has shown promising efficacy as a monotherapy and in combination with chemotherapy. This study examines the molecular structure of tislelizumab and its interaction with PD-1, along with its therapeutic effects and adverse reactions in NSCLC patients. Using GRAMM (Global Range Molecular Matching), protein–protein docking was conducted to analyze the binding affinity of tislelizumab with PD-1. A comprehensive search in PubMed, Embase, Cochrane Library, and Web of Science identified eligible studies, including randomized controlled trials (RCTs) and single-arm studies reporting survival outcomes, tumor responses, or adverse events. Tislelizumab significantly improved event-free survival (RR = 1.40, 95% CI: 1.19–1.65) and median progression-free survival (mPFS) by 1.77 months in RCTs, and reduced the risk of disease progression or death by 41% (HR = 0.59, 95% CI: 0.52–0.67). The overall survival risk was reduced by 35% (HR = 0.65, 95% CI: 0.59–0.73). The overall response rate (ORR) was higher in the tislelizumab group (RR = 1.86). In single-arm studies, the 1-year overall survival rate was 73.8%, with an ORR of 59.5%. AEs were generally manageable, with more frequent elevated ALT/AST, hypothyroidism, and rash, but fewer cases of anemia and neutropenia compared to chemotherapy. Tislelizumab significantly improves survival outcomes and tumor response rates in NSCLC patients, with an overall acceptable safety profile.

The precise cause of this multifaceted disease remains uncertain. Yet, genetic, genomic and proteomic research has enhanced our understanding of the disruption in its molecular signaling pathways. In this review, we attempted to highlight the regulation of autophagy pathways by a range of biocompounds (chemical compounds of biological origin) in osteosarcoma. Autophagy is a degradation mechanism, maintaining cellular homeostasis under basal and stress conditions. However, the role of autophagy is variable in cancer. There is a delicate balance between autophagy and apoptosis, and disruption of this balance is one of the causes of tumor formation and development. Autophagy and apoptosis can reciprocally activate or inhibit each other. Thus, autophagy works synergistically or antagonistically with apoptosis. In osteosarcoma, different biocompounds involve in the regulation of autophagy and/or apoptosis, triggering cellular signaling pathways, convenient or inconvenient for growth, proliferation, invasion and metastasis of cancer cells in a tumor. Also, some of the biocompounds have been shown to affect the therapeutic response of osteosarcoma cells.

In this research, BEAS-2B lung epithelial cells and MH-S alveolar macrophages were exposed to LPS and various concentrations of Daucosterol. Cell viability was assessed using CCK-8 assay. Glycolytic activity was evaluated by detecting ATP production, lactate level, and extracellular acidification rate. Macrophage polarization was assessed using flow cytometry. Tumor necrosis factor (TNF)-α and interleukin (IL)-6 levels were detected by enzyme-linked immunosorbent assay. Gene expression was evaluated by reverse transcription-quantitative polymerase chain reaction and western blotting. A cecal ligation and puncture (CLP)-induced ALI mouse model was used to validate the protective effect of Daucosterol in vivo. Results showed that Daucosterol prevented the reduction in cell viability in LPS-stimulated BEAS-2B cells. In MH-S macrophages, Daucosterol inhibited LPS-induced glycolysis and M1 polarization while promoting M2 polarization. Mechanistically, Daucosterol reversed the LPS-induced upregulation of PFKFB3. Overexpression of PFKFB3 counteracted the inhibitory effects of Daucosterol on glycolysis and M1 polarization. In vivo, Daucosterol significantly alleviated CLP-induced ALI by improving lung histopathology, reducing pulmonary edema, enhancing oxygenation, inhibiting myeloperoxidase and caspase-3 activity, and decreasing TNF-α and IL-6 levels in bronchoalveolar lavage fluid.

In this study, EIF2AK2 was overexpressed in INS1 cells, and transcriptome data following EIF2AK2 overexpression were obtained using RNA-seq technology. Additionally, potential target genes that bind to EIF2AK2 were identified through iRIP-seq technology. The proteins interacting with EIF2AK2 were characterized using co-immunoprecipitation (CO-IP) combined with mass spectrometry to elucidate the molecular regulatory mechanisms of EIF2AK2 in INS1 cells. RNA-seq results indicated that in INS1 cells overexpressing EIF2AK2, 1171 genes were differentially expressed, and 2161 alternative splicing events were significantly altered. iRIP-seq data demonstrated that reads from the immunoprecipitated samples were significantly enriched in the intronic and coding sequence (CDS) regions. EIF2AK2 preferentially binds to the GCGGCGG motif in RNA. Comprehensive analysis suggests that EIF2AK2 may directly bind to and regulate the expression of Dusp8, Btg1, and Prkce, thereby affecting pancreatic islet cell functions. Furthermore, EIF2AK2 may influence islet cell function by modulating the alternative splicing of Zfr and Pias2. Additionally, combined with Co-IP mass spectrometry data, it was discovered that EIF2AK2 can interact with 649 proteins, including various differentially expressed RNA-binding proteins, transcription factors, and histones, which may be associated with diabetes. Our results indicate that EIF2AK2 may regulate the expression or alternative splicing of mRNA related to type 2 diabetes through direct or indirect binding.

Oridonin (Ori), a natural tetracyclic diterpenoid, exhibits notable anti-tumor properties. However, its efficacy and underlying mechanism in LC remain to be elucidated. This study employed comprehensive network pharmacology, molecular docking, and molecular dynamic simulation to investigate the molecular targets and mechanisms underlying the anti-LC effects of Ori, followed by in vitro validation of its key mechanisms. A total of 172 potential therapeutic targets of Ori for LC were identified. GO and KEGG analyses indicated that Ori's anti-LC mechanism primarily involved the PI3K-Akt, Ras, MAPK, and Rap1 signaling pathways. The PPI network and molecular docking analyses revealed that AKT1, EGFR, and MAPK1 are potential core targets of Ori. Additionally, molecular dynamics simulations and bioinformatics analyses further confirmed that these proteins are key candidate targets. In vitro, Ori inhibited the proliferation of LC Hep-2 and TU212 cells, induced apoptosis, arrested the cell cycle at the G1 phase, and suppressed migration and invasion. WB assays further showed that Ori significantly downregulated p-AKT expression in the PI3K/AKT pathway. These findings indicate that Ori represents a promising therapeutic candidate for LC.</p>\u0000 </div>","PeriodicalId":143,"journal":{"name":"Chemical Biology & Drug Design","volume":"107 1","pages":""},"PeriodicalIF":3.3,"publicationDate":"2026-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145954390","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}
