BCL2L1 and Miyoshi myopathy: Considering that, among BCL-2 family members, the anti-apoptotic protein BCL-XL was previously found to be particularly important for survival of MM cells, including NCI-H28 and MSTO-211H [67], we analyzed by Western blotting its expression in these cell lines treated with dl922-947 and/or AZD1775, as described above.
