Oxygen tension-dependent variability in the cancer cell kinome and response to combination therapies
Ontology highlight
ABSTRACT: Solid tumors are characterized by significantly lower oxygen (O2) levels. Despite this fact, routine preclinical cancer studies are performed under ambient O2 conditions. We have developed an experimental approach that allows us to collect, process and evaluate cancer and non-cancer cells under physioxia (3-5% O2), in such a way that there is very minimal exposure to air. In addition to evaluating mouse mammary tumor cell lines with respect to kinome changes due to ambient and physioxic O2 tensions, we applied single cell-RNA sequencing to determine transcriptomic changes that occur in primary human breast epithelial cells that were collected, processed and cultured in ambient air and physioxia. We demonstrate that ambient and physioxic O2 tensions induce unique transcriptomic changes in primary human breast epithelial cells that are concurrent with our observations in the tumor cells.
