Special Issue Information

Dear Colleagues,

In the last decade, we have witnessed the increased popularity of high throughput screening (HTS) in academia for tool compound development and drug discovery. This has been largely fueled by the rapid developments at many fronts of biology, and the novel targets identified through these efforts. The creation of academic screening centers and the NIH Molecular Libraries Roadmap Initiative have spearheaded the effort and provided crucial infrastructural and technical support to many academic labs engaged in probe development and unravelment of fundamental biology using an HTS approach. With the continued growth of the academic drug discovery effort and the increased demands of high quality tool compounds, the interest in HTS will continue to increase among academic researchers. We thus would like to put together this Special Issue on HTS to highlight the most recent development in the many different fronts of HTS research, encompassing novel assay formats, new targets and screening technologies. We invite the submission of full articles and communications reporting recent work on biochemical, cell-based, phenotypic, and targeted screening. We also welcome timely reviews on the above topics and any other areas of HTS that will capture the interest and imagination of the HTS community.

We thank in advance for your contribution to this Special Issue on HTS.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page.

Title: Genome-wide microRNA profiling in the sacculus rotundus tissue of rabbit by high-throughput sequencing approach

Abstract: Rabbit is a widely used animal model for biomedical researches because of the phylogenetic relationship to human beings, short vital cycle, less aggressive behavior and other advantages. However, our basic researches on the genomic biology of rabbit have obviously lagged far behind. The sacculus rotundus is a specific gut-associated lymphoid tissue in rabbit and plays important roles for host immunity. In the present study, we first employed high-throughput sequencing approach to reveal the genome-wide microRNAs among more than 40 rabbits. Our results provide a set of reference microRNAs and hence facilitate the researches on biological implications of microRNAs in rabbit.

Title: Application of NanoBRET Technology to Quantitatively Determine Kinase Inhibitor Potency in Live Cells

Abstract: NanoBRET Technology is a first biophysical technique that broadly enables the quantitative determination of kinase inhibitor occupancy in live cells, without disruption of cellular membrane integrity. This live cell quantitative capability is achieved in live cells via BRET with an optimized set of cell-permeable kinase tracers. As the specificity of the BRET signal is dictated by the placement of NanoLuc on the chosen kinase target, a diverse set of broad-coverage tracers supports a method to profile kinase-specific affinity over a large portion of the kinome. NanoBRETTM TE has enabled the development of live cell quantitative compound binding assays for >200 individual full-length protein kinases, including a key panel of integral membrane kinase receptors. The assays were scaled to 384-well plate format and Z’ analysis demonstrated the assays to be HTS-compatible. Enabled by this new HTS capability, a systematic profiling of dasatinib against kinases was performed in both NanoBRETTM cellular and HotSpot™ biochemical assays. The comparative analysis revealed a surprising intracellular selectivity profile for this drug. IC50 profiling of reference compound panels against Abl1, DDR1 and c-Met were further tested in both assay formats for potency comparison. These results demonstrate high concordance between in vitro biochemical assay (HotSpot™) and cell-based assay (NanoBRETTM). This data strongly suggest the value of assessing live-cell kinase target engagement in parallel with the biochemical tests in kinase lead optimization programs, as the cellular environment may influence potency and selectivity profiles.

Title: Identification of compounds that inhibit estrogen-related receptor alpha (ERRα) signaling using high throughput screening assays

Abstract: The nuclear receptor, estrogen-related receptor alpha (ERRα; NR3B1), plays a pivotal role in energy homeostasis. Its expression fluctuates with the demands of energy production in various tissues. When paired with the peroxisome proliferator-activated receptor gamma coactivator 1a (PGC-1α), the PGC/ERR pathway regulates a host of genes which participate in metabolic signaling networks and in mitochondrial oxidative respiration. Unregulated overexpression of ERRα is found in many cancer cells, implicating a role in cancer progression and other metabolism related diseases. Using a high throughput screening assay approach, we previously identified several clusters of ERRα agonists in the Tox21 10K library. In the present study, we screened the Tox21 10K compound library using stably transfected HEK293 cells containing either the ERRα-reporter or the reporter plus PGC-1a expression vector. We identified two major groups of antagonist/inhibitor compounds that blocked ERRα activity and/or the PGC/ERR pathway.
