Breast cancer is the most prevalent cancer in women. Approximately 75% of breast cancers are estrogen receptor alpha positive (ER+) and are treatable with endocrine therapies and/or CDK inhibitors. However, endocrine therapy (ET) resistance and metastasis are major obstacles in advanced ERα+ breast cancer (ER+ BCa) therapeutics. Upregulated oncogenic ERα activity plays critical role in progression of ER+ BCa. One essential mechanism of regulating ERα signaling is the ubiquitination-dependent proteasomal degradation of ERα. Owing to its direct effect on ERα degradation, fulvestrant is a first-line FDA-approved ET for metastatic and locally advanced breast cancer and a second-line drug for treatment …

Breast cancer remains the second most prevalent cancer among women in the U.S. with metastatic breast cancer having the worst prognosis. A rapidly proliferating tumor under various stressors will promote phenotypic cellular changes, known as epithelial-to-mesenchymal transition (EMT), which allows cells to begin to invade surrounding tissue, enter the circulatory system, and eventually seed a distant metastatic site. The phospholipase D (PLD) enzymes are critical regulators of cell signaling pathways necessary for cell migration. While the importance of PLD enzymes in cancer cell invasion is well known, clinically applicable methods of PLD inhibition are not yet available. The best-studied isoforms …
