摘要: The annexin family and S100A associated proteins are important regulators of diverse calcium-dependent cellular processes including cell division, growth regulation apoptosis. Dysfunction individual is with cancer progression, metastasis drug resistance. This manuscript describes the novel finding differential by activation p53 in breast cells. Additionally, observed found to be beneficial survival cells influence treatment efficacy. We have used unbiased, quantitative proteomics determine proteomic changes occurring post p14ARF-p53 estrogen receptor (ER) In this report we identified annexin/S100A family, through unique peptide recognition at N-terminal regions, demonstrating a central orchestrator calcium favor pro-survival functions cell. was cell-type specific. Retrospective human studies demonstrated that tumors functional wild type (p53wt) respond poorly some chemotherapy agents compared non-functional p53. Given modulation signaling has been change sensitivity chemotherapeutic apoptotic signals, principle, explored paradigm how ER+ patients impacts influences therapeutic outcomes.
