Oncogenic signaling pathways as therapeutic targets in breast cancer

Our laboratory explores the mechanisms whereby non-receptor oncogenes and tumor suppressors alter cell signaling in breast cancer and develops genetic and pharmacological therapeutic approaches to intervene these pathological signaling cascades. The signaling circuitries are intervened in three-dimensional context using mammary epithelial cell line-based and ex vivo organoid cultures and in vivo models of mammary gland and breast cancer. Our recent work has exposed novel dependencies between tumor suppressor Lkb1 loss and serine protease activation, which pathways are relevant in tumor invasion. Furthermore, we investigate a metabolic addiction pathway connecting Myc-induced metabolic reprogramming via AMPK to p53 and mitochondrial apoptosis pathway. We are currently testing therapeutic intervention strategies specifically targeting deregulated serine protease pathways, cancer cell metabolism and apoptosis in preclinical models of breast cancer, hoping to translate scientific discoveries to clinical investigation and ultimately, to benefit of a cancer patient.
