Retinoic acid and Azakenpoullone treatment in SH-SY5Y/6TR(EU)/pTrex-Dest-30/MYCN cell line in high and low MYCN levels


ABSTRACT: The effect of the GSK3 inhibitor Azakenpaullone (Azak) and the differentiation agent retinoic acid (RA) was studied in low and high MYCN levels in the MYCN inducible neuroblastoma cell line SH-SY5Y/6TR(EU)/pTrex-Dest-30/MYCN (SY5Y-MYCN). Azak was dissolved in DMSO in order to apply it to the cells. Therefore a vehicle control consisting of SY5Y-MYCN cells treated with 24h 1 ul/ml DMSO only was used in duplicates. Doxycycline (Sigma) dissolved in water was used at a final concentration of 1ug/ml to induce MYCN expression in SY5Y-MYCN. A co-treatment study with Dox and Azak was conducted. SY5Y-MYCN cells were treated with 24h Azak, 24h Azak & 48h Dox and 48h Dox, with biological duplicates. 1 uM RA (dissolved in DMSO) and 1 ug/mL Doxycycline were given individually and in combination. SY5Y-MYCN cells were treated with 24h RA, 24h RA & 48h Dox, and 48h Dox and RNA was extracted in biological duplicates. For the 24h RA & 48h Dox co-treatment cells were treated with Dox for 24h and then with RA and fresh Dox for a further 24h.

Despite intensive study, many mysteries remain about the MYCN oncogene's functions. Here we focus on MYCN's role in neuroblastoma, the most common extracranial childhood cancer. MYCN gene amplification occurs in 20% of cases, but other recurrent somatic mutations are rare. This scarcity of tractable targets has hampered efforts to develop new therapeutic options. We employed a multi-level omics approach to examine MYCN functioning and identify novel therapeutic targets for this largely un-drugga  ...[more]
