This study aimed to evaluate the protective effect of Amlo against CP- and Aceta-induced nephrotoxicity in rats, with particular emphasis on renal GGT activity and oxidative stress. Fifty-six male albino rats were randomly allocated into seven groups receiving normal saline, CP, Aceta, Amlo, or their respective combinations.

Cisplatin markedly elevated renal GGT activity, oxidative stress parameters, and renal dysfunction markers, whereas Aceta induced a milder but significant renal injury. Amlodipine treatment attenuated GGT overactivation, reduced oxidative stress, and improved renal functional and histological integrity, while Aceta co-administration exacerbated CP-induced renal damage. Collectively, these findings indicate that CP induces more pronounced renal GGT activation and oxidative injury than Aceta, and that Amlo confers significant nephroprotection, underscoring the critical role of GGT in drug-induced nephrotoxicity.</div></div>","PeriodicalId":8966,"journal":{"name":"Biomedicine & Pharmacotherapy","volume":"197 ","pages":"Article 119187"},"PeriodicalIF":7.5,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147358030","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

T14 is elevated in presymptomatic AD and initiates a pathological cascade involving calcium influx, mTORC1 activation, impaired autophagy, and β-amyloid accumulation. To interrupt this sequence, the cyclated variant of T14, NBP14, was developed, with consequent cognitive benefits in a preclinical mouse model. However, the high molecular weight of NBP14 posed potential limitations for therapeutic translation, prompting the design of NBP6B, a shorter, linear 6-mer variant with improved efficacy and bioavailability. This study aimed to evaluate the efficacy of NBP6B in antagonising T14-induced toxicity in comparison with two novel small molecules, which due to their lower molecular weight could have greater therapeutic potential. Using PC12 cells, T14 activity was assessed through calcium influx and cell viability assays, alongside therapeutic rescue by the drug candidates. To evaluate receptor specificity, α7-nAChR overexpression was employed to determine whether the small molecules acted via α7-dependent or independent pathways. While the small molecules offered favourable drug-like properties and potential for improved blood–brain barrier (BBB) permeability, NBP6B exhibited greater potency and selectivity, with effective antagonism in the nanomolar range, compared to the micromolar concentrations required for the small molecules. These findings thus support NBP6B as a promising and selective α7-targeted therapeutic for early-stage intervention in AD.</div></div>","PeriodicalId":8966,"journal":{"name":"Biomedicine & Pharmacotherapy","volume":"197 ","pages":"Article 119125"},"PeriodicalIF":7.5,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147358025","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their mechanistic interaction in cancer remains undefined, particularly in gastric cancer (GC). Several interconnections have been described between these two “bioactive lipids” involved in inflammation resolution, homeostatic and anti-tumour functions. Cannabinoid signalling can modulate SPM biosynthesis in immune cells, thus we investigated whether this crosstalk operates in GC cells, and whether SPMs mediate part of the anti-tumour activity of cannabinoid receptors. Using synthetic and selective agonists for the cannabinoid G-protein-coupled receptors CB1 and CB2 (ACEA and JWH133, respectively), we found that receptor activation in GC cells (AGS and MKN45) sustains the synthesis of two SPMs, Resolvin D1 and Lipoxin B4, which in turn suppresses the angiogenic potential of GC cells. These CB1/CB2-driven activities required a SRC/MAPK signalling. At physiological concentrations, these SPMs further enhanced the binding affinity of ACEA and JWH133 for CB1 and CB2, indicating a functional crosstalk between the two systems. Beyond angiogenesis, CB1/2 stimulation reduced cell proliferation and viability, induced apoptosis, impaired the migration and the epithelial-to-mesenchymal program in GC cells. Only CB2 activation reduced the stemness properties of GC cells. Interestingly, while the anti-angiogenic properties of CB1 and CB2 required SPM production, their other anti-tumour actions were independent of the pro-resolving pathway. Our results extend the current knowledge of the endocannabinoid system by defining a new dual mechanism, SPM-dependent and SPM-independent, that restrains GC progression and identify the ECS-SPM axis as a potential target for therapeutic intervention.</div></div>","PeriodicalId":8966,"journal":{"name":"Biomedicine & Pharmacotherapy","volume":"197 ","pages":"Article 119186"},"PeriodicalIF":7.5,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147349983","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although immune checkpoint inhibitors have improved outcomes in advanced disease, immune resistance remains a critical barrier to durable responses, emphasizing the need to define the molecular mechanisms underlying therapeutic failure. Interleukin (IL)30 has been identified as a cancer progression driver with immunosuppressive function in the tumour-microenvironment. Whether it is involved in melanoma aggressiveness and metastasis is unknown. Immunopathological studies, RNA-Seq and CIBERSORTx analyses of tissue samples from the <em>TCGA-SKCM</em> patient cohort, reveal that IL30 expression is absent in normal skin, while it can be found in melanoma and infiltrating immune cells, mostly macrophages. The putative IL30 receptor complex, IL-6Rα/gp130, is expressed by melanoma cells, which respond to IL30 stimulation with increased proliferation and migration, consistent with IL30-mediated upregulation of metastasis-associated genes, including ANG2, CXCR4, ITGB1, MMP2, NME, SNAI2, VEGFA, VEGFC, and L1CAM. Bioinformatic analysis of IL30 transcript levels in TCGA-SKCM tissue specimens, reveals increased IL30 expression in metastases compared with primary tumors, corroborating the experimental findings at the translational level. IL30 reprograms the melanoma immunophenotype by inducing multiple immune checkpoint molecules, including LSECtin, LGALS3, LGALS9, LAG-3, TIM-3, B7-H4, B7-H3, VISTA, and PD-1. Concurrently, IL30 suppresses T cell function by reducing CD25 and HLA-DR expression on CD4⁺ and CD8⁺ T cells, inhibiting their activation and proliferation, decreasing TNF-α and IFN-γ production, and boosting LAG-3 expression, which strongly correlates with IL30 levels in clinical samples.
