Abstract

Background: MYCN amplification is a prognostic biomarker associated with poor prognosis of neuroblastoma in children. The overall survival of children with MYCN-amplified neuroblastoma has only marginally improved within the last 20 years. The Bromodomain and Extra-Terminal motif (BET) inhibitor, JQ1, has been shown to downregulate MYCN in neuroblastoma cells.

Objective: To determine if JQ1 downregulation of MYCN in neuroblastomas can offer a target- specific therapy for this, difficult to treat, pediatric cancer.

Methods: Since MYCN-amplified neuroblastoma accounts for as much as 40 to 50 percent of all high-risk cases, we compared the effect of JQ1 on both MYCN-amplified and non-MYCN-amplified neuroblastoma cell lines and investigated its mechanism of action.

Results: In this study, we show that JQ1 can specifically target MYCN for downregulation, though this effect is not specific to only MYCN-amplified cells. And although we can confirm that the loss of MYCN alone can induce apoptosis, the exogenous rescue of MYCN expression can abrogate much of this cytotoxicity. More fascinating, however, was the discovery that the JQ1-induced knockdown of MYCN, which led to the loss of the human double minute 2 homolog (HDM2) protein, also led to the accumulation of tumor protein 53 (also known as TP53 or p53), which ultimately induced apoptosis. Likewise, the knockdown of p53 also blunted the cytotoxic effects of JQ1.

Conclusion: These data suggest a mechanism of action for JQ1 cytotoxicity in neuroblastomas and offer a possible prognostic target for determining its efficacy as a therapeutic.

Keywords: Cancer, oncology, neuroblastoma, BET inhibitors, p53, pediatric, MYCN amplifications, JQ1.
