Understanding of molecular mechanisms regulating leukemia stem cell behavior by multi-omics analysis

mTOR is an evolutionarily conserved kinase in eukaryotes that plays a critical role in sensing and responding to factors such as nutrient availability, energy sufficiency, stress, hormones, and mitogens. Since it was reported that mTOR complex 1(mTORC1) dysregulation promotes leukemogenesis and depletes hematopoietic stem cells, we attempted to understand the pathological roles of mTORC1 in leukemia behavior by multi-omics technology. In this study, we found that there are particular cell population showing obvious resistance to mTORC1 inactivation, and found several candidate molecules that are involved in the regulation of leukemia stem cells.
