PVT1 and acute lymphoblastic leukemia: Then, lncRNA-pvt1 was transfected into Jurkat cells, and the apoptosis of the transfected Jurkat cells was detected by flow cytometry, to explore the mechanism of lncRNA-pvt1 in the pathogenesis of childhood acute lymphoblastic leukemia, in order to find new molecular biological indicators for the early detection of ALL and disease monitoring and evaluation in the future and to provide new targets for future molecular therapy.
