Dose response of the BET inhibitor JQ1 in Small-Cell Lung Cancer cell lines.


ABSTRACT: This is a Dose response experiment carried out using the BET inhibitor JQ1 in SCLC cell lines. Approximately 1x106 cells of cell lines, DMS-53, H69, H1694, H1048, H2227 were treated for 2 hours with a 12 point dose range of JQ1 (7500nM to 0.04nM). Lysates were collected at the end of the treatment in 300ul TRI reagent for RNA preparation for expression profiling.

The BET (bromodomain and extra-terminal) proteins bind acetylated histones and recruit protein complexes to promote transcription elongation. In hematologic cancers, BET proteins have been shown to regulate expression of MYC and other genes that are important to disease pathology. Pharmacologic inhibition of BET protein binding has been shown to inhibit tumor growth in MYC-dependent cancers, such as multiple myeloma. In this study, we demonstrate that small cell lung cancer (SCLC) cells are exqu  ...[more]
