TLR4 signaling of LPS chemotypes in HEK Blue hTLR4 reporter cells.

ABSTRACT: The discovery of Toll-like receptors (TLRs) represented a significant breakthrough that paved the way for the study of host-pathogen interactions in innate immunity. However, there are still major gaps in understanding TLR function, especially the early dynamics of downstream TLR pathways remains less clear. We characterize a label-free optical biosensor-based assay as a powerful method to detect TLR activation in a native and label-free environment and to delineate the dynamics of TLR pathway activation. To gain a deeper insight into the biological processes underlying the ligand-specific signal traces of different LPS chemotypes in various cell types, RNA-seq analysis of transcriptional changes in HEK Blue hTLR4 reporter cells was performed. After 3 hours of stimulation with LPS E. coli or LPS S. minnesota, HEK Blue hTLR4 reporter cells showed significant changes in RNA expression compared to the unstimulated control.

RNA-Sequencing of STING competent and STING-KO cells after transfection with dacA (Listeria monocytogenes)

Project description:HEK-Blue™ ISG Cells and HEK-Blue™ ISG-KO-STING Cells (Invivogen) were transfected with dacA (Listeria monocytogenes) for 12 and 24 hours. Through this approach, we described the STING-dependent and STING-independent transcriptional response to dacA. Our analysis reveals a STING-dependent enrichment of interferon stimulated genes beginning 12 hours post-transfection, and a STING-independent enrichment of genes associated with protein translation and oxidative phosphorylation.

Comprehensive map of the Artemisia annua proteome and quantification of differential protein expression in chemotypes producing high vs low content of artemisinin

Project description:Artemisia annua is well known for biosynthesizing artemisinin, which is the primary therapeutic approach against malaria. It was reported that treatment with leaf of A. annua showed better effect and less tendency of developing drug resistance than purified artemisinin, suggesting other components in A. annua may contribute to the therapeutic efficacy. Here, we conducted a global proteomic profiling of A. annua with identification of a total of 13,403 proteins based on the genome sequence annotation database. Furthermore, we generated a spectral library to perform quantitative proteomic analysis using data independent acquisition mass spectrometry (DIA-MS). Specifically, we comprehensively quantified and compared proteins between two chemotypes that produce high (HAP) and low (LAP) artemisinin content, respectively. 182 proteins were identified with abundance significantly different between these two chemotypes. Overall, our current study globally identified the proteome of A. annua and quantitatively compared the targeted sub-proteomes between the two cultivars of HAP and LAP, providing systematic information on metabolic pathways of A. annua and facilitating identification of good chemotypes for producing anti-malaria compounds.

Streamlined DNA-encoded small molecule library screening and validation for the discovery of novel chemotypes targeting BET proteins (RNA-seq)

Project description:Targeting aberrant epigenetic programs that drive tumorigenesis is a promising approach to cancer therapy. DNA-encoded small-molecule library (DEL) screening is a core platform technology increasingly used to identify drugs that bind to protein targets. Here, we use DEL screening against bromodomain and extra-terminal motif (BET) proteins to identify inhibitors with new chemotypes, and successfully identified BBC1115 as a selective BET inhibitor. While BBC1115 does not structurally resemble OTX-015, a clinically active pan-BET inhibitor, our intensive computational modeling and biological characterization revealed that BBC1115 binds to BET protein BRD4 and suppresses aberrant cell fate programs. Phenotypically, BBC1115-mediated BET inhibition impaired proliferation in acute myeloid leukemia, pancreatic, and colorectal cancer cells in vitro. Moreover, intravenous administration of BBC1115 inhibited subcutaneous pancreatic and colorectal cancer xenograft growth with minimal toxicity and favorable pharmacokinetic properties in vivo. Since epigenetic regulations are ubiquitously employed across normal and malignant cells, it will be critical to evaluate whether BBC1115 interferes with normal cellular functions. Nonetheless, our study implicates that integrating DEL-based small-molecule compound screening and multi-step biological validation represents a reliable strategy to discover new chemotypes with selectivity, efficacy, and safety profiles for targeting proteins involved in epigenetic regulation in human malignancies.

BMM_C3H/HeJ_LPS_timecourse

Project description:Bone marrow derived macrophages (BMM) total RNA from C3H/ARC mice extracted after stimulation by LPS at different time points. Each time point stimulated with 10ug/ml LPS from Salmonella minnesota for the time indicated. The RNA from each BMM stimulated time point was labeled with Cy3 and compared with a common reference (total RNA from C57BL6/J 17.5 embryo) labeled with Cy5.
