In this study we demonstrate that IFNalpha treatment of the two myeloma cell lines, U266-1984 and U-1958, results in the decrease of STAT3 activity as demonstrated by a diminished STAT3/3 DNA-binding activity and the shift from STAT3/3 towards STAT1/1 and STAT3/1 complexes in EMSA, leading to the down-regulation of known STAT3 target genes such as Bcl-X(L), Mcl-1 and survivin.

Highly expressed genes in MM cells included cell survival pathway genes such as mcl-1, dad-1, caspase 8, and FADD-like apoptosis regulator (FLIP); oncogenes/transcriptional factors such as Jun-D, Xbp-1, calmodulin, Calnexin, and FGFR-3; stress response and ubiquitin/proteasome pathway-related genes and various ribosomal genes reflecting increased metabolic and translational activity.

IHC of multiple myeloma patient bone marrow biopsies and aspirates (n = 95) revealed high levels of BCL-2 and BCL-XL in 62% and 43% of evaluable samples, respectively, while 34% were characterized as BCL-2(High)/BCL-XL (Low) In addition to MCL-1, our data suggest that BCL-XL may also be a potential resistance factor to venetoclax monotherapy and in combination with bortezomib.
