Effect of Dose Irradiation on the Expression of BRCA1 and BRCA2Genes in MCF-10A and MCF-7 cell lines [PDF]

Iranian Journal of Medical Physics, 2023
Introduction: Breast cancer can be caused by a mutation in its genome. Some mutations are cancer-predisposition which exist at the moment of germ cell genesis. It has been discovered that BRCA1 and BRCA2 are linked to hereditary breast cancer.
