Conditions

acute myeloid leukemia

Interventions

VEN Sensitivity Group:An AML cell line with CLL-1 knockout was constructed and co-cultured with different concentrations of VEN. AML patients with refractory relapse and CLL-1 expression bigroups were
Mechanism group of VEN resistance:AML cell lines and CLL-1 knockout AML cell lines were selected and co-cultured with appropriate concentrations of VEN
AML patients with refractory relapse and CLL-1 expression bigroups were sorted by flow cytometry or immunomagnetic beads, and co-cultured with appropriate concentrations of VEN
AML cell lines and CLL-1 knockout AML cell lines with ROR1-NF-?B pathway inhibitors added
For AML patients with refractory relapse and CLL-1 expression bigroups, ROR1-NF-?B pathway inhibitors were added
