These findings highlight the pivotal role of DNA-PKcs status in shaping the DNA damage response and radiosensitivity of glioblastoma cells. Targeting compensatory repair pathways in DNA-PKcs-deficient tumors may offer novel strategies for radiosensitization in glioblastoma therapy.
This approach represents a real-time surrogate biomarker for treatment response for a disease where imaging-based assessment of response has not been shown to be reliable. Future prospective validation is warranted.
We found that P2RX7, MMP15 and MMP16 are upregulated in neurosphere cells, indicating a potential role for these genes in tumor formation. Together these results reveal global transcriptional profiles of GL261 cells, establish a resource for further scRNA-Seq-based analyses, and give insight into gene expression changes relevant to glioblastoma tumor development.
This novel approach of electrochemical H2O2 delivery holds significant potential for enhancing targeted cancer therapies, offering a controllable, precise, and efficient method for inducing tumor cell death while minimizing damage to healthy tissues. These results showcase the remarkable ability of PEDOT electrodes as a reliable electrocatalytic source of on-demand H2O2 in electrochemically-challenging biological environments.
Presented results suggest that CLDNs may serve as biomarkers for diagnosis and prognosis as well as therapeutic targets in CNS tumors. Further investigation is essential to clarify their clinical relevance and therapeutic potential.
