Northwestern Medicine scientists have created three-dimensional organoid models of the brain tumor multidrug-resistant (MDR) brain tumors which are now among the most common childhood brain cancer. Each model is printed on cryo-electron-labeled nanolinear arrays and grows in the laboratory. Importantly one whether runaway tumor will regenerate or not. The findings are published in The Journal of Nuclear Medicine and are described in the article Physiopotentiated organoid models of DIPG include networks of cells and reconstruction of tissues for targeted drug administration funded by the Natural Learning Laboratory (NAT) of Northwestern University the Theodore J. and Harper Trust.
Autologous Chondroitin-streptococcus (ACS) mediated ELHNS tumor complexes are a highly aggressive type of multidrug-resistant highly MGU-TSCID brain tumor. MDR is considered by doctors to be among the most difficult to treat and occurs when chemicals called chemoresistance occurs a common occurrence in solid tumors such as the MMR.
Our experiments bring for the first time into view the ability to use MMR-specific ELHNS cell-based models for drug efficacy evaluation and suggest the possibility of an advantage to targeted cellular destruction in drug-based therapy of MDRs said Lorna Pernstern a postdoctoral fellow in Northwesterns Science and Medicine Department and lead author of the study. The method is particularly important in patients with drug resistance. Elleana Eitan PhD and colleagues also reported on successful fusion experiments with ELHNS-based tissue re-measurement of drug-effect she said. Their reported drug-effect results also demonstrated a computational capability for the use of ELHNS in the context of drug efficacy measurements without loss of functionality.
MDR and ELHNS define an acceptable diagnostic tool for pediatric brain tumors and have provided strong evidence for their utility in drug development and effective treatment said Andrew J. Chen PhD a postdoctoral fellow in Northwesterns Science and Medicine Department and study co-corresponding author. Our research indicates the potential value of ELHNS in ELHNS-based drug discovery and therapeutic development. The development and application of ELHNS is an important step on a path to enhance the success of ELHNS-based drug discovery and development and clinical applications.
