(ATCC, HTB77), OVCAR-3 (ATCC, HTB-161),
OVCAR-8 (inherited from Laurent Brad’s previous laboratory),
and CAOV-3 (ATCC, HTB75) ovarian cancer cells were grown in complete
DMEM media (Gibco, 11965). IGROV-1 (Sigma, SCC203) and 2008 (kindly
provided by Dr. François X. Claret, University of Texas M.D.
Anderson Cancer Center) ovarian cancer cells were grown in complete
RPMI medium (Gibco, 22400). ES2 (ATCC, CRL-1978) was grown in McCoy’s
5A complete medium (ATCC, 30-2007). BE(2)C (ATCC, CRL-2268), SH-EP1
(ATCC, CRL-2269), SH-SY5Y (ATCC, CRL-2266), KELLY (Sigma, 92110411),
SK-N-AS (Sigma, 94092302), and LAN-5 (COG,
cell-lines were maintained in RPMI1640 media (Gibco, 11875) supplemented
with 10% heat-inactivated FBS. TH-MYCN+/+ cells were derived by mechanical
dissociation of tumors obtained from TH-MYCN homozygous mice51 (link)−53 (link) and were maintained in RPMI1640 media (Gibco, 11875) supplemented
with 20% heat-inactivated FBS, 10–5 mM 2-mercaptoethanol, 1
mM sodium pyruvate, and 1× nonessential amino acids (Gibco, 11140076).
