Onco-Innovations’ Licensed Technology Shown in Study to Successfully Prevent Regeneration of Cancer Cells (ACCESSWIRE) - "Onco-Innovations Limited...is pleased to provide information on its exclusively-licensed technology, a new class of Polynucleotide Kinase 3'-Phosphatase (PNKP) inhibitors (the 'Technology'), which was shown in a study to successfully prevent the regeneration of cancer cells, by disrupting DNA repair processes, making cancer cells more vulnerable to radiation therapy and thereby improving patient outcomes. Onco-Innovations' new generation of PNKP inhibitors targets a key enzyme involved in cancer cell DNA repair. By inhibiting PNKP, these compounds can prevent cancer cells from repairing damage caused by radiation therapy, significantly boosting the therapy's effectiveness."
