The cell lines used in this study: AU565, BT20, BT474, BT483, BT549, HCC1143, HCC1500, HCC1569, HCC1937, HCC1954, HCC38, HCC70, Hs578T, MDA-MB-134, MDA-MB-175, MDA-MB-361, MDA-MB-436, MDA-MB-453, MDA-MB-468, SKBR3, and ZR751 were obtained from ATCC, Rockville, MD, USA. MCF-7 cells were obtained from Michigan Cancer Foundation, Detroit, MI, USA. The cell lines HBL100, MDA-MB-157, MDA-MB-231 and T47D were obtained from EG&G Mason Research Institute, Worcester, MA, USA.
The cell lines AU565, BT20, BT474, BT549, HBL100, Hs578T, MCF-7, MDA-MB-134, MDA-MB-157, MDA-MB-175, MDA-MB-231, MDA-MB-361, MDA-MB-436, MDA-MB-453, MDA-MB-468, SKBR3, T47D and ZR571 were cultured in RPMI 1640 medium supplemented with 10% heat-inactivated fetal bovine serum (FBS), 6 mM L-glutamine, 20 mM HEPES and 10 μg/ml human insulin (CSL-Novo, North Rocks, NSW, Australia). The remaining cell lines were cultured in RPMI 1640 medium supplemented with 10% heat-inactivated FBS, 6 mM L-glutamine, 1 mM sodium pyruvate and 20 mM HEPES. The MYC over-expressing MCF7 cells have been previously described
[11 (link),27 (link)] and were cultured in the same conditions as the parental cells.
The CDK4/6 inhibitor PD0332991 was purchased from Selleck Chemicals (Houston, TX, USA), CDK2 inhibitor SNS-032 from Symansis (Auckland, New Zealand) and CDK1 inhibitors, RO-3306 and CGP74514A, from Calbiochem (San Diego, CA, USA).

The drugs listed below were acquired from Selleck chem: FGFR inhibitors PD166866 (specific to FGFR1), Alofanib (targeting FGFR2), H3B-6527 (inhibiting FGFR4), and AZD4547 (effective against FGFR1-3), pan-FGFR inhibitor TAS-120, JAK inhibitors Solcitinib (inhibiting JAK1) and AZD1480 (inhibiting JAK2), UC2288 (p21 inhibitor), STAT inhibitors Fludarabine (inhibiting STAT1),
Stattic (inhibiting STAT3) and BAY2353 (Niclosamide, inhibiting STAT3), SGC-CBP30 (potent CREBBP/EP300 inhibitor), and ulixertinib (ERK1/ERK2 inhibitor). Human EGF protein and FGF ligands including FGF1, FGF2, FGF4, FGF7, FGF9, FGF8a, FG19 and FGF21 were purchased from PeproTech. The breast cancer cell lines CAMA1, MDA-MB-134, MCF7, and T47D were obtained from the American Type Culture Collection (ATCC). The CAMA1 and MCF7 cell lines were grown in DMEM with a 10% FBS and 1% antibiotic-antimycotic solution, while T47D and MDA-MB-134 were cultured in RPMI with 10% FBS and 1% antibiotic-antimycotic solution. Regular testing for mycoplasma contamination was conducted using the commercially available Myco Alert kit from Lonza. All cell lines utilized in this research have undergone authentication by ATCC, and only cells with a low number of passages were employed in experiments to ensure work confidence.
