(A) MM.1S and RPMI8226 cells were treated by TM (0-10μg/ml), and cell growth was assessed by
20
MTT assay. Data represent mean ± s.d. in quadruplicate. (B, C) MM.1S cells were treated with TM
21
(0-10μg/ml) for 24 h (B) or TM (10μg/mL) for 0-12 h (C). Whole cell lysates were immunoblotted
22
with indicated antibodies, and α-tubulin was used as loading control.

MM1R, U266, DOX40, H929, OPM2, KMS11 and ANBL-6.BR cells were treated with indicated dose

of TMP269 and CFZ for 48 h, and cell growth was assessed by MTT assay. Data represent mean ±

Cytotoxic effect of TMP269 combined with CFZ against patient MM cells
14
Patient MM cells were treated with or without TMP269 (10μM) in the presence or absence of CFZ
15
(4nM) for 48 h, and cell growth was assessed by MTT assay. Data represent mean ± s.d. in
16
triplicate. * p< 0.05 compared to control.

ANBL-6.WT and ANBL-6.BR cells were treated with indicated doses of CFZ, and cell growth was
21
assessed by MTT assay. Data represent mean ± s.d. in quadruplicate.
