A Novel Approach to Interrogating the Effects of Chemical Warfare Agent Exposure Using Organ-on-a-Chip Technology and Multiomic Analysis

Project description:Organ-on-a-chip platforms are utilized in global bioanalytical and toxicological studies as a way to reduce materials and increase throughput as compared to in vivo based experiments. These platforms bridge the infrastructure and regulatory gaps between in vivo animal work and human systems, with models that exemplify active biological pathways. In conjunction with the advent of increased capabilities associated with next generation sequencing and mass spectrometry based ‘-omic’ technologies, organ-on-a-chip platforms provide an excellent opportunity to investigate the global changes at multiple biological levels, including the transcriptome, proteome and metabolome. When investigated concurrently, a complete profile of cellular and regulatory perturbations can be characterized following treatment with specific agonists. In this study, global effects were observed and analyzed following liver chip exposure to the chemical warfare agent, VX. Even though the primary mechanism of action of VX (i.e. acetylcholinesterase inhibition) is well characterized, recent in vivo studies suggest additional protein binding partners that are implicated in metabolism and cellular energetic pathways. Also, secondary toxicity associated with peripheral organ systems, especially in human tissues, is not well defined. Our results demonstrate the efficacy of utilizing an organ-on-a-chip platform as a surrogate system to traditional in vivo studies. This is realized by specifically indicating significant dysregulation of a number of cellular processes in response to VX exposure including but not limited to amino acid synthesis, drug metabolism, and energetics pathways.

Multiomic (Joint snRNA/snATAC) sequencing data of intestinal crypts and epithelial only organoids derived from human fetal duodenum

Project description:Here, we used joint single-nuclei RNA-sequencing (snRNA-seq) and single-nuclei ATAC sequencing (scATAC) to profile freshly isolated crypts from the human fetal intestine and matched intestinal epithelial only organoids (also known as enteroids) derived from these crypts after one passage of in vitro growth. Organoids were grown in the standard 25% LWRN media with either 100 ng/ml of EGF or 1 ng/ml of EREG added. Fresh crypts were not placed in culture but rather immediately frozen for multiomic processing.

Single nucleus RNA-seq, ATAC-seq, and multiomic sequencing of adult human kidney

Project description:In this study, we generated a single nucleus multiomic (snRNA-seq and snATAC-seq) dataset of adult human kidney. We developed a bioinformatic tool to analyze this dataset by identifying key cis-regulatory elements and transcription factors associated with specific cell types and states. We applied this tool to identify transcription factors implicated in proximal tubule cell injury and failed repair states. We demonstrate this tool can be applied to single cell multiomic datasets to derive insight into cell type- and state-specific gene regulatory networks.
