We singled out SGK1, which showed an inverse correlation between its mRNA levels and WT1 in leukemic cell lines and AML samples. In cellular models, forced expression of WT1 reduced mRNA and protein levels of SGK1. Furthermore, WT1 repressed the SGK1 promoter activity, and accordingly, WT1 knockdown showed an increased expression of SGK1. We also detected an inverse correlation between WT1 and SGK1 during leukemic cell-line differentiation. WT1 genetic knockdown displayed decreased cell viability under nutrient deprivation.

This cohort included patients with AML who underwent their first HSCT between 2016 and 2021. CPR was evaluated at three time points: at diagnosis, after initial therapy, and pre-HSCT.
