Interestingly, population B resembles cluster 3 identified in this publication, which was characterized by high expression of mesenchymal markers, including SNAI2, and low expression of proliferative genes, such as KI67, PCNA, and CCND1. Population B expresses low levels of AKT1, and AKT1low cancer cells have been reported to be quiescent cells that survive chemotherapy in breast tumors (Kabraji et al., 2017). Here, AKT1 is linked to cancer.
