Dear Editor,In T-cell acute lymphoblastic leukemia(T-ALL),an aggressive hematologic cancer with poor clinical outcomes,more than 50%of cases show NOTCH1-driven transformation[1].The NOTCH1 receptor signaling pathway is activated through a series of proteolytic cleavages,ultimately causing the release of the active intracellular domain(NICD),which translocates to the nucleus where it promotes transcription of target genes involved in cell growth.The importance of NOTCH1 mutations in T-ALL has generated great interest in the development of anti-NOTCH1 targeted therapies.A new and promising emerging field in cancer treatment is medical cannabis.Accumulating evidence suggests the direct effects of cannabis on tumor progression in cell lines and animal models[2].Cannabis,and its unique secondary metabolites,known as phytocannabinoids,directly affect the propagation of cancer cells by modulating key cellsignaling pathways[3].We have previously demonstrated that different cannabis extracts,each containing a unique composition of metabolites,selectively impaired the survival of cancer cell lines depending on amatch between the chemical composition of the extract and the characteristics of the specific cancer cell line[4].In the present work,we set out to investigate whether cannabis extracts with unique phytocannabinoid profiles can selectively facilitate antitumor effects in T-ALL cells that harbor a Notch1 mutation.
