It is still incurable due to de novo or acquired resistance of malignant cells to standard chemotherapies. Thus, understanding the mechanism of therapeutic resistance is essential to develop better interventions and identifying new therapeutic targets. MM is a heterogeneous disease characterized by complex genetic alterations, which are critical for prognostic stratification. Due to the heterogeneity and clinical challenges associated with MM, there remains a critical need for novel biomarkers to improve both early diagnosis and prognostic accuracy. Antioxidants participate in protecting cancer cells from the damaging effects of oxidative stress by neutralizing reactive oxygen species. These molecules may have their own role in myeloma progression and drug resistance. However, studies reported contradictory ideas regarding the levels and roles of antioxidants in MM. The main aim of this review is to conceptualize the diagnostic, prognostic, and therapeutic significance of common antioxidants for MM. The most common antioxidant systems discussed in this study were DJ-1, glutathione, thioredoxin, and superoxide dismutase. The review revealed that antioxidants are overexpressed in myeloma cells compared to normal plasma cells. This excess expression of antioxidants increases tumor cells' survival and their chemoresistance leads to poor prognosis and short survival of myeloma patients. Thus, antioxidants and their synthesis pathways may have a promising prognostic, diagnostic, and therapeutic role in MM. Vitamin C (ascorbic acid), on the other hand, has a two-faced role in cancer, including MM. It can function as an antioxidant (increase myeloma cell resistance to chemotherapy) or pro-oxidant (enhance the therapeutic effect of myeloma drugs), depending on its dose and route of administration. Pharmacological (ultra-high) doses of vitamin C administered intravenously may act as a pro-oxidant that can selectively kill myeloma cells by elevating the cellular labile iron pool and generating extracellular H₂O₂.</p>","PeriodicalId":23048,"journal":{"name":"Therapeutic Advances in Hematology","volume":"17 ","pages":"20406207261419810"},"PeriodicalIF":2.8,"publicationDate":"2026-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12923940/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147271986","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}

{"title":"Translational insights from nonclinical studies of AAV gene therapies for hemophilia: mechanisms underpinning variability and durability of gene expression.","authors":"Sylvia Fong, Laura L Swystun, Paul Batty, David Lillicrap","doi":"10.1177/20406207251406537","DOIUrl":"10.1177/20406207251406537","url":null,"abstract":"<p><p>Adeno-associated virus (AAV) gene therapy is a promising approach for hemophilia, offering the potential for sustained therapeutic expression of coagulation factors. However, both variability and durability of transgene expression remain a challenge, limiting treatment predictability. Comparative preclinical and human liver biopsy studies suggest that transcriptional efficiency, rather than vector genome copy number (VCN), is a primary determinant of variability and durability in treatment response. Despite the presence of vector genomes in hepatocytes, transcriptional output varies significantly across species and individuals, indicating that VCN alone is insufficient to predict therapeutic efficacy. This review synthesizes findings from preclinical models (mice, dogs, non-human primates (NHPs), and human hepatocytes) and clinical liver biopsy studies to examine mechanisms influencing AAV gene therapy variability and durability. While vector genome retention is relatively comparable across species, transcriptional efficiency declines in higher species, particularly in NHPs, dogs, and humans. Beyond transcription, vector genome loss, hepatocyte turnover, immune responses, and cellular stress (e.g., endoplasmic reticulum (ER) stress) may contribute to intraindividual declines in transgene expression over time. Recent findings also highlight the role of epigenetic modifications, vector integration patterns, and translational shutdown linked to protein-folding stress in influencing durability. Expression patterns show greater long-term stability with factor IX (FIX) gene therapy compared to factor VIII (FVIII), which often declines more sharply. Distinctions may reflect differences in protein biosynthetic burden and cellular stress responses, particularly for FVIII. Most FIX trials use the highly active Padua variant, enabling lower expression levels with potentially less cellular stress, while the tendency of FVIII to misfold and trigger ER stress may contribute to transcriptional or translational shutdown over time. Integrating insights from preclinical models, human liver biopsies, and ongoing clinical trials, this review refines our understanding of AAV gene therapy variability and durability, ultimately guiding next-generation gene therapies to enhance long-term clinical efficacy.</p>","PeriodicalId":23048,"journal":{"name":"Therapeutic Advances in Hematology","volume":"17 ","pages":"20406207251406537"},"PeriodicalIF":3.1,"publicationDate":"2026-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12855745/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146107385","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}
