PIK3CD and acute lymphoblastic leukemia: In general, our data showed in mono application settings stronger anti-proliferative effects of AraC and DEX in comparison to the PI3K-inhibitor on the cells and on the molecular biological processes (gene expression, pathway regulation, proliferation, metabolism, and apoptosis) in the examined pro-B-ALL cells in vitro–comparable analyses are to the best of our knowledge not documented in literature.
