- W3040396580 abstract "Abstract Late recurrences of breast cancer are hypothesized to originate from disseminated tumor cells that re‐activate after a long period of dormancy, ≥5 years for estrogen‐receptor positive (ER+) tumors. An outstanding question remains as to what the key microenvironment interactions are that regulate this complex process, and well‐defined human model systems are needed for probing this. Here, a robust, bioinspired 3D ER+ dormancy culture model is established and utilized to probe the effects of matrix properties for common sites of late recurrence on breast cancer cell dormancy. Formation of dormant micrometastases over several weeks is examined for ER+ cells (T47D, BT474), where the timing of entry into dormancy versus persistent growth depends on matrix composition and cell type. In contrast, triple negative cells (MDA‐MB‐231), associated with early recurrence, are not observed to undergo long‐term dormancy. Bioinformatic analyses quantitatively support an increased “dormancy score” gene signature for ER+ cells (T47D) and reveal differential expression of genes associated with different biological processes based on matrix composition. Further, these analyses support a link between dormancy and autophagy, a potential survival mechanism. This robust model system will allow systematic investigations of other cell‐microenvironment interactions in dormancy and evaluation of therapeutics for preventing late recurrence." @default.
