The BET protein inhibitor JQ1 reduces c-Myc expression and attenuates primary MCC cell proliferation. A, decreased c-Myc expression in MCC-3 and MCC-5 treated with JQ1 (800 nmol/L) for 72 hours by qRT-PCR and immunoblotting. The mRNA expression of target genes was normalized to that of MRPS2 and a value of 1.0 was assigned to the mRNA expression of target genes in the control group (means+SEM; **, P < 0.01 vs. control); b-actin was used as a loading control for immunoblotting.

B. Repressed MCC-3 xenograft tumor growth upon combined treatment with MLN0128 and JQ1. Tumor bearing mice were treated with MLN0128 or vehicle at 1 mg/kg/day by oral gavage and JQ1 or vehicle at 50 mg/kg/day by i.p. injection for a period of 30 days. C. A more effective reduction of MCC-3 xenograft tumor growth in the group treated with combined therapy. Fold-reduction of tumor growth was calculated as average tumor growth of control group divided by average tumor growth of treatment group. Tumor growth was calculated as final average tumor volume minus initial average tumor volume in each group.

Frequently Asked Questions
-
Question 1:
How can I reconstitute the compound for in vivo injection?
-
Answer:
JQ1 does not dissolve in water/PBS. The vehicle we recommend is 2% DMSO+30% PEG 300+5% Tween 80+ddH2O. The compound can be dissolved in the vehicle at 5mg/ml and you can use it for IV injection.
