Title:

Inhibition of BCL2A1 by STAT5 inactivation overcomes resistance to targeted therapies of FLT3-ITD/D835 mutant AML

Published date:

Excerpt:
However, a type I TKI, gilteritinib, inhibited the expression of BCL2A1 through inactivation of STAT5 and alleviated TKI resistance of FLT3-ITD/D835. The combination of gilteritinib and venetoclax showed synergistic effects in the FLT3-ITD/D835 positive AML cells. The promoter region of BCL2A1 contains a BRD4 binding site. Thus, the blockade of BRD4 with a BET inhibitor (CPI-0610) downregulated BCL2A1 in FLT3-mutated AML cells and extended profound suppression of FLT3-ITD/D835 mutant cells. Therefore, we propose that BCL2A1 has the potential to be a novel therapeutic target in treating FLT3-ITD/D835 mutated AML.

Title:

BCL2A1: A Novel Target in Refractory/Relapsed AML with FLT3-ITD/D835 Double Mutations

Published date:
09/01/2021
Excerpt:
Gilteritinib targets BCL2A1 through inactivation of STAT5, and combinatorial gilteritinib and venetoclax were highly synergistic in FLT3-ITD/ D835 double-positive cells. Furthermore, inhibition of BRD4 with the BET inhibitor CPI-0610 exhibited anti-tumor activity in FLT3-ITD/D835 double-positive AML and suppressed BCL2A1 expression in these cells.

2785 BCL2A1: A Novel Target in Refractory Acute Myeloid Leukemia with FLT3-ITD/D835 Dual Mutations

Excerpt:
...examined effects of CPI-0610, a BET inhibitor, on MV4-11 cells with FLT3-ITD or the FLT3-ITD/D835 dual mutation. CPI-0610 inhibited cell growth of MV4-11 cells by inducing apoptosis irrespective of co-existing FLT3 mutations (IC50: FLT3-ITD/D835, 255 nM vs. FLT3-ITD, 191 nM, 72h).
