Abstract Outcomes for pediatric acute myeloid leukemia (AML) have improved significantly in recent years. However, relapsed and refractory disease remains a significant problem. The chemotherapy burden experienced by these patients makes the translational development of non-genotoxic experimental therapies attractive. We previously reported that the anti-helminth drug mebendazole induces degradation of the transcription factor MYB and has potent anti-AML activity.

Abstract Refractory cancers may arise either through the acquisition of resistance mechanisms or represent distinct disease states. The origin of childhood T-cell acute lymphoblastic leukaemia (T-ALL) that does not respond to initial treatment, i.e. refractory disease, is unknown. Refractory T-ALL carries a poor prognosis and cannot be predicted at diagnosis. Here, we perform single cell mRNA sequencing of T-ALL from 58 children (84 samples) who did, or did not respond to initial treatment.

Abstract The medial prefrontal cortex (mPFC) is critical for learning and decision-making processes, including responding to threats. The protracted maturation of the mPFC extends into early adulthood. Although prominent models suggest that increasing top–down control by the mPFC eventually allows adult behavioral repertoires to emerge, it is unclear how progressive strengthening can produce nonlinear behavioral changes observed across development.
