CRaTER enrichment for on-target gene-editing enables generation of variant libraries in hiPSCs

Project description:Generation of transgenic cell lines is limited by inefficient gene editing requiring genotypic screening of hundreds to thousands of colonies to isolate correctly gene-edited cells. Here, we describe a novel method called CRISPRa On-Target Editing Retrieval (CRaTER) that enriches for cells with on-target knock-in of a promoterless cDNA-fluorescent reporter transgene by transiently overexpressing the targeted endogenous genetic locus and sorting for fluorescent cells. We use CRaTER to enrich for rare cells with heterozygous, biallelic-editing of the endogenous, transcriptionally-inactive MYH7 locus in human induced pluripotent stem cells (hiPSC), resulting in a 9-fold enrichment compared to antibiotics selection alone. We leveraged CRaTER to enrich for heterozygous knock-in of a library of single nucleotide variants (SNV) in MYH7, a gene encoding for sarcomeric MHC-β wherein autosomal dominant missense mutations cause cardiac and skeletal myopathies. CRaTER enabled 90% enrichment of heterozygous, biallelically-edited hiPSCs – a 38.6-fold enrichment compared to antibiotics selection alone – to generate 113 SNVs comprising 78 missense variants in MYH7. hiPSCs that have undergone CRaTER enrichment can differentiate to cardiomyocytes and exhibit expected localization and expression of MHC-β fusion proteins. Together, CRaTER substantially reduces the screening required for isolation of gene-edited cells, enabling the generation of transgenic cell lines at unprecedented scale.

Assessing the Potential Ecological Impacts of Perfluorinated Chemicals (PFCs) in the liver and testis of male largemouth bass (Micropterus salmoides) in Minnesota Lakes

Project description:This study used an emerging analytical technology (cDNA microarrays) to assess the potential effects of PFC exposure on largemouth bass in TCMA lakes. Microarrays simultaneously measure the expression of thousands of genes in various tissues from organisms exposed to different environmental conditions. From this large data set, biomarkers (i.e., genes that are expressed in response to an exposure to known stressors) and bioindicators (e.g., suites of genes that correspond to changes in organism health) can be simultaneously measured to clarify the relationship between contaminant exposure and organism health. Based on current scientific literature, we hypothesized that gene expression patterns would be altered in fish exposed to PFCs (as compared with fish from reference lakes), and that the magnitude of these changes would correspond to the concentrations of PFCs present throughout TCMA lakes. Patterns of gene expression in largemouth bass observed across the TCMA lakes corresponded closely with PFC concentration. Concentrations of PFCs in largemouth bass varied significantly across the sampled lakes, where the lowest concentrations were found in Steiger and Upper Prior Lakes and the highest concentrations were found in Calhoun and Twin Lakes. Patterns of gene expression were most different (relative to controls) in fish with the highest PFC tissue concentrations, where fish from Twin and Calhoun Lakes were observed to have between 5437 and 5936 differentially expressed genes in liver and gonad tissues. Although gene expression patterns demonstrated a high degree of correlation with PFC concentrations, microarray data also suggest there are likely additional factors influencing gene expression patterns in largemouth bass in TCMA lakes.

Regional Epigenetic Variation in Asexual Snail Populations among Urban and Rural Lakes

Project description:Epigenetic variation has the potential to control environmentally dependent development and contribute to phenotypic responses to local environments. Environmental epigenetic studies of sexual organisms confirm the responsiveness of epigenetic variation, which should be even more important when genetic variation is lacking. A previous study of an asexual snail, Potamopyrgus antipodarum, demonstrated that different populations derived from a single clonal lineage differed in both shell phenotype and methylation signature when comparing lake versus river populations. Here, we examine methylation variation among lakes that differ in environmental disturbance and pollution histories. The differential DNA methylation regions (DMRs) identified among the different lake comparisons suggested a higher number of DMRs and variation between rural Lake 1 and one urban Lake 2 and between the two urban Lakes 2 and 3, but limited variation between the rural Lake 1 and urban Lake 3. DMR genomic characteristics and gene associations were investigated. Observations suggest there is no effect of geographic distance or any consistent pattern of DMRs between urban and rural lakes. Environmental factors may influence epigenetic response.
