In tumors, notably in gliomas, <i>IDH1</i> and <i>IDH2</i> are frequently mutated. The mutation found in different cancers is functionally active, causing, instead of α-KG, the formation of 2-hydroxyglutarate (2-HG), which inhibits α-KG-dependent enzymes. Gliomas harboring mutated <i>IDH1/2</i> show a better prognosis than <i>IDH1</i> wild-type (wt) tumors of the same grade, which might result from the inhibition of DNA repair functions. A DNA repair enzyme dependent on α-KG is alkB homolog 2 (ALKBH2), which removes several lesions from DNA. These findings prompted us to investigate the response of glioma cells to artesunate (ART), a plant ingredient with genotoxic and anticancer activity currently used in several trials. <b>Materials and Methods</b>: We used isogenic glioblastoma cell lines that express IDH1 wild-type or, based on a TET-inducible system, the IDH1 mutant (mt) protein, and treated them with increasing doses of artesunate. We also treated glioblastoma cells with 2-HG, generated ALKBH2 knockout cells, and checked their sensitivity to the cytotoxic effects of artesunate. <b>Results</b>: We show that the cell-killing effect of ART is enhanced if the IDH1 mutant (R132H) is expressed in glioblastoma cells. Further, we show that 2-HG imitates the effect of IDH1mt as 2-HG ameliorates the cytotoxicity of ART. Finally, we demonstrate that the knockout of ALKBH2 causes the sensitization of glioblastoma cells to ART. <b>Conclusions</b>: The data indicate that ALKBH2 protects against the anticancer effect of ART, and the mutation of IDH1/2 commonly occurring in low-grade gliomas sensitizes to ART via an ALKBH2-dependent mechanism.

SLE has the potential to impact any segment of the respiratory system, exhibiting a range of severity levels throughout the different stages of the disease. Pulmonary manifestations in SLE patients can be classified as primary (i.e., directly related to SLE and to immune-mediated damage), secondary to other SLE manifestations (e.g., nephrotic syndrome, renal failure, congestive heart failure), and comorbidities (e.g., infections, cancers, overlapping primary respiratory diseases). Understanding and correctly managing lung involvement in SLE is crucial because pulmonary complications are common and can significantly impact morbidity and mortality in affected patients. Early recognition and appropriate treatment can prevent irreversible lung damage, improve quality of life, and reduce the risk of life-threatening complications. Treatment algorithms are based on the suppression of inflammation, with or without the need for dedicated, supportive care. According to disease severity, available treatments include nonsteroidal anti-inflammatory drugs, corticosteroids, immunosuppressants, and biological agents. In this review, we aim to summarize the current knowledge on lung involvement in SLE and then focus on the management and treatment approaches available for the different forms.</p>","PeriodicalId":8937,"journal":{"name":"Biomedicines","volume":"13 6","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12191131/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144494206","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
