Cardiac tissues were studied using
caffeine (50 mM in water; Sigma-Aldrich),
amiodarone hydrochloride (2.418 μM in
DMSO; Sigma-Aldrich),
isoproterenol hydrochloride (a series of drug concentrations in water; Sigma-Aldrich), or
doxorubicin hydrochloride (1 μM in
DMSO; Sigma-Aldrich), all diluted in RPMI Medium 1640 supplemented with B-27™. Response to
isoproterenol was analyzed 10 minutes after exposure to 1 mM
isoproterenol hydrochloride, diluted in RPMI Medium 1630 supplemented with B27™.
ES bone tumor cell lines and tissues were studied using either
doxorubicin hydrochloride (10 mM in water; Sigma-Aldrich), linsitinib (OSI-906) (various concentrations in
DMSO; Santa Cruz Biotechnology), all diluted in either non-metastastic media (RPMI Medium 1640, 10% FBS, 1% PenStrep) or metastatic media (EMEM, 10% FBS, 1% PenStrep).
Both tissues were treated with linsitinib, dissolved at a 10 mM concentration in
DMSO (Corning) and mixed in with the respective cell medium at a 12 mM concentration unless otherwise noted. Vehicle treatments involved just the addition of
DMSO at identical volumes as a control. Tissues were randomly assigned to experimental groups. Medium was changed every day.
