The Long and Short of CDK12 Mutations

Mutations in the BRCA1 and BRCA2 genes pose a serious risk for breast and ovarian cancer because they endanger the genomic stability of a cell by interfering with homologous recombination repair (HR), a key mechanism for accurately repairing harmful double-stranded breaks in DNA. Without the ability to use HR to fix double-stranded breaks, the cell is forced to resort to more error-prone—and thus more cancer-prone—forms of DNA repair

Tumour-Vasculature Development After Radiotherapy

Despite recent technological advances in radiotherapy, challenges relating to tumor targeting, dose limitations, and tumor relapse and escape remain. Multiple strategies for targeting cancer cells, cancer stem cells (CSCs), tumor stroma, and tumor endothelial cells (ECs), as well as improving anti-tumor immune responses to increase tumor radiosensitivity, are being developed
