    Description: The efficacy of therapeutics is dependent on a drug binding to its cognate target. Optimization of target engagement by drugs in cells is often challenging, because drug binding cannot be monitored inside cells. We have developed a method for evaluating drug binding to target proteins in cells and tissue samples. This cellular thermal shift assay (CETSA) is based on the biophysical principle of ligand-induced thermal stabilization of target proteins. Using this assay, we validated drug binding for a set of important clinical targets and monitored processes of drug transport and activation, off-target effects and drug resistance in cancer cell lines, as well as drug distribution in tissues. CETSA is likely to become a valuable tool for the validation and optimization of drug target engagement.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Martinez Molina, Daniel -- Jafari, Rozbeh -- Ignatushchenko, Marina -- Seki, Takahiro -- Larsson, E Andreas -- Dan, Chen -- Sreekumar, Lekshmy -- Cao, Yihai -- Nordlund, Par -- New York, N.Y. -- Science. 2013 Jul 5;341(6141):84-7. doi: 10.1126/science.1233606.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medical Biochemistry and Biophysics, Karolinska Institute, Stockholm, Sweden.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23828940" target="_blank"〉PubMed〈/a〉

    Description: The thermal stability of proteins can be used to assess ligand binding in living cells. We have generalized this concept by determining the thermal profiles of more than 7000 proteins in human cells by means of mass spectrometry. Monitoring the effects of small-molecule ligands on the profiles delineated more than 50 targets for the kinase inhibitor staurosporine. We identified the heme biosynthesis enzyme ferrochelatase as a target of kinase inhibitors and suggest that its inhibition causes the phototoxicity observed with vemurafenib and alectinib. Thermal shifts were also observed for downstream effectors of drug treatment. In live cells, dasatinib induced shifts in BCR-ABL pathway proteins, including CRK/CRKL. Thermal proteome profiling provides an unbiased measure of drug-target engagement and facilitates identification of markers for drug efficacy and toxicity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Savitski, Mikhail M -- Reinhard, Friedrich B M -- Franken, Holger -- Werner, Thilo -- Savitski, Maria Falth -- Eberhard, Dirk -- Martinez Molina, Daniel -- Jafari, Rozbeh -- Dovega, Rebecca Bakszt -- Klaeger, Susan -- Kuster, Bernhard -- Nordlund, Par -- Bantscheff, Marcus -- Drewes, Gerard -- New York, N.Y. -- Science. 2014 Oct 3;346(6205):1255784. doi: 10.1126/science.1255784.

    Description: Transcription factors (TFs) direct gene expression by binding to DNA regulatory regions. To explore the evolution of gene regulation, we used chromatin immunoprecipitation with high-throughput sequencing (ChIP-seq) to determine experimentally the genome-wide occupancy of two TFs, CCAAT/enhancer-binding protein alpha and hepatocyte nuclear factor 4 alpha, in the livers of five vertebrates. Although each TF displays highly conserved DNA binding preferences, most binding is species-specific, and aligned binding events present in all five species are rare. Regions near genes with expression levels that are dependent on a TF are often bound by the TF in multiple species yet show no enhanced DNA sequence constraint. Binding divergence between species can be largely explained by sequence changes to the bound motifs. Among the binding events lost in one lineage, only half are recovered by another binding event within 10 kilobases. Our results reveal large interspecies differences in transcriptional regulation and provide insight into regulatory evolution.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3008766/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3008766/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schmidt, Dominic -- Wilson, Michael D -- Ballester, Benoit -- Schwalie, Petra C -- Brown, Gordon D -- Marshall, Aileen -- Kutter, Claudia -- Watt, Stephen -- Martinez-Jimenez, Celia P -- Mackay, Sarah -- Talianidis, Iannis -- Flicek, Paul -- Odom, Duncan T -- 062023/Wellcome Trust/United Kingdom -- 079643/Wellcome Trust/United Kingdom -- 15603/Cancer Research UK/United Kingdom -- 202218/European Research Council/International -- A15603/Cancer Research UK/United Kingdom -- WT062023/Wellcome Trust/United Kingdom -- WT079643/Wellcome Trust/United Kingdom -- Cancer Research UK/United Kingdom -- New York, N.Y. -- Science. 2010 May 21;328(5981):1036-40. doi: 10.1126/science.1186176.
