Article Title: RGX-019-MMAE inhibits leukemia progression by targeting MER proto-oncogene tyrosine kinase (MERTK) in acute myeloid leukemia

doi: 10.1186/s13046-026-03657-y

Figure Lengend Snippet: The antibody-drug conjugate RGX-019-MMAE induced cytotoxic activity in MERTK-expressing AML cell lines. A MERTK expression in the indicated AML cell lines; leukemic cells (1 × 10 6 ) were stained with anti-MERTK-APC antibody, and the expression was measured by flow cytometry. Data are plotted as mean values with error bars representing standard error. B - F Bar graph showing the percentage of relative luminescence in Kasumi 1 ( B ), OCI-AML3 ( C ), MOLM-13 ( D ), MOLM-14 ( E ), and MV4-11 ( F ) cells treated with the indicated concentrations of RGX-019-MMAE and monoclonal antibody RGX-019. Data are plotted as mean values with error bars representing standard error (Student unpaired t -test). * p ≤0.05, ** p ≤0.01, *** p ≤0.001, **** p ≤0.0001. UT = untreated

doi: 10.1186/s13046-026-03657-y

Figure Lengend Snippet: The antibody-drug conjugate RGX-019-MMAE induced cytotoxic activity in MERTK-expressing AML primary cells. A - D Bar graphs show the percentage of relative luminescence in primary AML cells, RGX946 ( A ), RGX694 ( B ), RGX702 ( C ), and RGX470 ( D ) treated with the indicated concentrations of RGX-019-MMAE or the monoclonal antibody RGX-019. Data are plotted as mean values with error bars representing standard error (Student unpaired t -test). E Representative figures of colony-forming units for normal peripheral blood mononuclear cells in response to DMSO and indicated concentrations of RGX-019-MMAE and RGX-019.
