This work aims to examine the involvement of mitochondrial dysfunction, oxidative stress, and caspase activation in mediating ramucirumab induced cytotoxicity in Caco-2 cells. MTT (3-(4, 5-dimethylthiazolyl-2)-2, 5-diphenyltetrazolium bromide) and lactate dehydrogenase (LDH) tests were used to measure cell viability and cytotoxicity, respectively by exposing Caco-2 cells to ramucirumab for 24 h.

Additionally, the expression of the apoptotic markers caspase-3 and caspase-7, and levels of VEGF was quantified. Ramucirumab enhanced the release of LDH, and significantly (p < 0.05) decreased cell viability with increasing concentration and IC<sub>50</sub> value was estimated as 780 µg/ ml.

Two-pore channel 2 (TPC2), an endolysosomal ion channel, has been implicated in pigmentation, vesicular trafficking, and cancer-related cellular processes, but its role in melanoma remains incompletely understood. In this study, we investigated the impact of TPC2 loss in two melanoma models, the human cell line CHL-1 and the murine cell line B16, using previously validated CRISPR/Cas9-generated TPC2 knockout cells. Proteomic profiling, pathway enrichment analysis, extracellular flux measurements, and mitochondrial membrane potential assessment were used to define the molecular and functional consequences of TPC2 deletion. Proteomic analysis revealed marked but distinct changes in protein expression in CHL-1 and B16 cells, with clear separation between wild-type and TPC2 KO proteomic profiles in both models. Functional enrichment analysis showed that CHL-1 cells were preferentially associated with pathways related to metabolic regulation, morphogenesis, intracellular transport, extracellular matrix organization, and signaling networks including WNT and TGF-β, whereas B16 cells were enriched in immune/interferon-related pathways, protein homeostasis, intracellular trafficking, and stress-response programs. Bioenergetic profiling demonstrated that TPC2 KO altered cellular metabolism in a cell line-dependent manner. In CHL-1 cells, TPC2 loss reduced basal oxygen consumption rate (OCR) and the OCR/ extracellular acidification rate (ECAR) ratio, but enhanced oxidative adaptation under glucose-free conditions. In contrast, B16 TPC2 KO cells displayed increased OCR and ECAR under basal conditions, consistent with a more energetically active phenotype. Despite these differences in basal bioenergetics, TPC2 KO preserved mitochondrial membrane potential under stress in both cell lines, indicating enhanced mitochondrial stress resilience. Collectively, these findings identify TPC2 as a context-dependent regulator of melanoma cell physiology that influences proteomic remodeling, metabolic adaptation, and mitochondrial function.

Current treatments often show limited efficacy and adverse effects. The family Apiaceae is traditionally valued for its medicinal uses, particularly anti-inflammatory effects, and among its members are Deverra tortuosa (Desf.) DC. (D. tortuosa) and Deverra triradiata Hochst. ex Bioss. (D. triradiata) with recognized therapeutic value. As nanotechnology-based formulations enhance skin penetration and therapeutic efficacy, this study investigated the antipsoriatic activity of plant-based nanocreams (NCs). Phenolic content of D. tortuosa and D. triradiata aerial parts was analyzed by high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). Nanoparticles were prepared with droplet sizes of 300-470 nm and a positive surface charge. Mice were divided into five groups: control (cream base), imiquimod (IMQU; 62.5 mg/day for 7 days), a commonly used inducer of psoriasis-like dermatitis, standard (tacrolimus 20 mg/kg/day, 2 h after IMQU), IMQU + D. triradiata NC (2% once daily, 2 h after IMQU), and IMQU + D. tortuosa NC (2% once daily, 2 h after IMQU). D. tortuosa and D. triradiata NCs significantly alleviated IMQU-induced systemic and skin-related psoriatic changes in mice by reducing spleen index, inflammatory cytokines, including interleukin-17 (IL-17), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-α), as well as nuclear factor kappa-B (NF-κB), signal transducer and activator of transcription-3 (STAT3), and Ki-67 expression. Histological analysis confirmed marked restoration of normal skin architecture, with D. tortuosa showing the highest therapeutic efficacy. These findings suggest that D. tortuosa and D. triradiata NCs possess promising anti-psoriatic potential, through immunomodulatory and anti-inflammatory mechanisms, with D. tortuosa demonstrating superior efficacy. They may serve as effective natural alternatives to conventional psoriasis treatments.</p>","PeriodicalId":49257,"journal":{"name":"Saudi Pharmaceutical Journal","volume":"34 3","pages":""},"PeriodicalIF":4.3,"publicationDate":"2026-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13212808/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148036804","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
