Gli-oma, as a neuroepithelial cancer of the glial cells, is one of the rarest malignancies which has a low survival rate. The exact risk factors of glioma are still not clear, but allergy, ionizing radiation, and hereditary factors are reported to be associated with glioma. Nrf2 as an antiox-idant regulator has been reported to be highly expressed in malignances tissues like glioma. Nrf2 regulates the expression of various antioxidant and cytoprotective genes. In gliomas, Nrf2 activation helps tumor cells combat oxidative stress by enhancing the production of de-toxifying enzymes (e.g., glutathione peroxidase, NADPH quinone oxidoreductase). This al-lows glioma cells to survive and proliferate in toxic tumor microenvironments rich in reactive oxygen species (ROS). Although the role of Nrf2 in the apoptosis of cancerous glial cells is not clear yet, it has been shown that Nrf2 inhibition via different methods can increase the efficiency of the chemo-therapy agents to treat glioma. Elevated Nrf2 activity has been linked to drug resistance in gliomas. The activation of Nrf2 increases the expression of multidrug resistance-associated proteins (MRPs) and other detoxifying enzymes, which limit the effectiveness of chemother-apeutic agents like temozolomide (TMZ). Nrf2 inhibitors can suppress the signaling pathway of Nrf2 and decrease the expression of detoxifying enzymes like SOD, CAT, GPX, and GCL, which can increase the efficiency of chemotherapy agents. Using drugs that inhibit the Nrf2 expression in combination with classical chemotherapy agents can be a promising procedure to decrease chemoresistance and be effective in increasing the survival rate of patients with glioma. In this study, we focused on the association of glioma and Nrf2 expression and its targeting as a new therapeutic approach in glioma treatment.</p>","PeriodicalId":10816,"journal":{"name":"Current cancer drug targets","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143432621","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}

Due to its high rate of incidence, innovative and effective treatments are crucial. Among these, immunothera-peutic approaches have emerged as transformative, offering new hope by harnessing the body's immune system to target and eliminate cancerous cells. Immunotherapy has changed the treatment landscape for skin cancer, providing options such as checkpoint inhibitors and adoptive cell transfer therapies that specifically enhance immune activity against tumors. De-spite these advancements, the broader adoption of immunotherapeutic modalities is challeng-ing due to concerns about their toxicity and variable efficacy.

Nanotechnol-ogy-based approaches show promise in improving the delivery and effectiveness of cancer therapies, particularly for skin cancer immunotherapy. Nanoparticles can deliver therapeutic agents directly to tumors, minimizing systemic toxicity and enhancing treatment precision. These strategies also boost the immune system's ability to target cancer cells while overcom-ing the limitations of current immunotherapies.

ABCB9 analysis showed opposite results, with survival rates of 55% and 91% in the presence of amplification and normal copy number, respectively (p=0.006). ABCC subfamily genes showed a similar result in the presence of amplification, where ABCC3 and ABCC10 account for 64% and 60% survival, respectively (p=0.005, p=0.01).</p><p><strong>Conclusion: </strong>Thus, not only expression but also chromosomal aberrations were found to be associated with patient survival. These findings could be a potential marker of metastatic-free survival.</p>","PeriodicalId":10816,"journal":{"name":"Current cancer drug targets","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143122350","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}
