- 요약Breast cancer is the most common invasive cancer diagnosed in women worldwide. While advances in early detection and treatments have led to a decrease in mortality, there is still a critical need to develop novel therapeutic strategies for specific breast cancer (BC) subtypes. Triple negative breast cancer (TNBC) is one of the most aggressive subtypes that lacks the expression of the estrogen, progesterone, and HER2 receptors and disproportionately impacts young Black women. Consequently, there is a dire need for developing novel options for treating TNBC. Here, we examine the current clinical and preclinical scientific understanding of combination therapies, including combining small molecule inhibitors and radiotherapy, for the treatment of TNBC.Our first studies demonstrated that the inhibition of monopolar spindle kinase I (Mps1 or TTK) is a radiosensitizing strategy in syngeneic models of TNBC. TTK is serine threonine kinase that plays a crucial role in cell division by ensuring proper chromosome separation during mitosis. We built upon prior work that showed TTK is upregulated in primary breast cancers and that TTK inhibition radiosensitizes TNBC in human preclinical models. We expanded on these findings and tested whether the combination of TTK inhibition and radiotherapy induces radiosensitization in syngeneic TNBC models to investigate the role of the immune system and its antitumoral activity in TNBC. We first examined the induced expression of cellular type I interferon (T1IFN) following combination therapy. We next discovered that TTK inhibition radio sensitized syngeneic models of breast cancer and induced micronuclei formation in vitro. TTK inhibition also radio sensitized syngeneic TNBC in vivo and induced T1IFN signaling across human and murine TNBC cells. These studies nominate TTK inhibition and radiotherapy as a promising therapeutic strategy for improving tumor control and activating the immune system in TNBC.In another novel line of research, we examined the therapeutic potential of combining radiotherapy with Aurora kinase B (AURKB) inhibition. AURKB is a serine threonine kinase that is part of the chromosomal passenger assembly complex and plays diverse roles in cellular division. AURKB is upregulated in many solid tumors, and prior research suggests that AURKB is a promising target for cancer treatment. However, the radiosensitizing potential of AURKB in TNBC is not currently understood. Therefore, we set out to determine whether AURKB inhibition will radiosensitize TNBC in preclinical models. We also found that AURKB inhibition radiosensitizes both human and murine TNBC cell lines and potentiates cellular T1IFN signaling in vitro.Collectively, this thesis furthers our scientific understanding of the therapeutic potential of combinational strategies for treating TNBC. Existing work in the field also emphasizes the importance of understanding the disparities in breast cancer treatment and accessibility to care, treatment, and outcomes. Collectively, this thesis outlines and elucidates novel therapeutic strategies for the treatment of TNBC. These preclinical experiments illuminate the radiosensitizing potential of mitotic inhibitors for the treatment of TNBC. This work also highlights the underlying implications that such therapies have on antitumoral T1IFN signaling. Importantly, this research supports the preclinical rationale for translating these findings into clinical trials to help improve outcomes for patients with breast cancer.
