Abstract:

Breast cancer is one of the malignant tumours with the highest incidence rate among women and has become a major killer threatening women’s health. There are various treatment modalities for breast cancer, including surgery, radiotherapy, chemotherapy, endocrine therapy and targeted therapy.Combination therapy is effective in prolonging patient survival. But resistance to chemotherapy is increasing,and the search for new therapeutic targets is an urgent clinical problem in order to achieve better clinical outcomes for breast cancer patients. E1A binding protein P300 (EP300) is a widely expressed transcriptional co-activator and histone acetyltransferase that acetylates conserved lysine residues in histones to promote activated transcription of genes. EP300 is a protein molecule with multiple functional structural domains that can modulate the interactions between multiple proteins. EP300 has important and diverse biological functions in cell proliferation, cell cycle regulation, apoptosis, DNA damage repair and stem cell-like properties. EP300 has now been shown to be associated with tumour recurrence in breast cancer and suggests poor prognosis. The relationship between EP300 and the development of breast cancer is now reviewed.

Key words: Breast neoplasms, EIA binding protein P300, EP300 inhibitor
