In triple-negative breast cancer, there is low expression of hormone receptors (ER and PR) and HER2 gene, increased expression of genes involved in cell cycle regulation, such as Cyclin B1 and CDC20, high expression of genes involved in DNA damage repair, such as RAD51 and BRCA1, and high expression of genes involved in immune response and inflammation, such as IFNγ and TNFα. The gene discussed is NR4A1; the disease is triple-negative breast carcinoma.
