Changes in the transcript profile due to ABCA1 expression in murine liver samples was evaluated in LDL receptor -/- genetic backgrounds.
ABCA1 overexpression in the liver of LDLr-KO mice leads to accumulation of pro-atherogenic lipoproteins and enhanced atherosclerosis.

View SamplesFoxA transcription factors play major roles in organ-specific gene expression. How FoxA proteins achieve specificity is unclear, given their broad expression patterns and requirements in multiple cell types. Here, we characterize Sage, a basic helix-loop-helix (bHLH) transcription factor expressed exclusively in the Drosophila salivary gland (SG). We identify Sage targets and show that not only are both Sage and the single Drosophila FoxA protein, Fork head (Fkh), required for expression of these genes, but coexpression of Sage and Fkh is sufficient to drive target gene expression in multiple other cell types. Sage and Fkh drive expression of the bZip transcription factor Senseless (Sens), which boosts expression of Sage/Fkh targets. Importantly, Sage, Fkh and Sens colocalize on salivary gland polytene chromosomes. Thus, Fkh drives cell-type specific gene expression as part of a tissue-specific transcription module that includes Sage and Sens, providing a new paradigm for how mammalian FoxA proteins acheive specificity.

View SamplesThe targeting of oncogenic ‘driver’ kinases with small molecule inhibitors has proven to be a highly effective therapeutic strategy in selected non-small cell lung cancer (NSCLC) patients. However, acquired resistance to targeted therapies invariably arises and is a major limitation to patient care. ROS1 fusion proteins are a recently described class of oncogenic driver, and NSCLC patients that express these fusions generally respond well to ROS1-targeted therapy. In this study, we sought to determine mechanisms of acquired resistance to ROS1 inhibition. To accomplish this, we generated a ROS1 inhibition-resistant derivative of the initially sensitive NSCLC cell line HCC78.
