1 Jul 2020 Talking about teamwork, the Kampmann Lab team from UCSF really set first genome-wide CRISPRi & CRISPRa screens in human neurons.
Genome-wide screening then utilizes cells stably expressing dCas9-KRAB (CRISPRi), photoactivatable fluorescent protein (PA-mCherry), and a lentiviral guide RNA (gRNA) pool. Cells are screened by using microscopy and classified by artificial intelligence (AI) algorithms, which precisely identify the genetically altered phenotype.
We present a robust technology enabling systematic investigation of the cellular consequences of repressing or inducing individual transcripts. We identify rules for specific targeting of transcriptional In this presentation, Martin Kampmann will introduce functional genomics approaches in iPSC-derived neurons and glia. Specifically, Kampmann will: - Cover CRISPRi (interference) and CRISPRa (activation) control of gene expression. - Describe how to implement CRISPRi/a in iPSC-derived cells. - Introduce large-scale genetic screens based on survival, fluorescent readouts of cell function, single 2021-04-08 Genome-wide screening then utilizes cells stably expressing dCas9-KRAB (CRISPRi), photoactivatable fluorescent protein (PA-mCherry), and a lentiviral guide RNA (gRNA) pool.

Describe how to implement CRISPRi/a in iPSC-derived cells. Introduce large-scale genetic screens based on survival, fluorescent readouts of cell function, single-cell RNA sequencing, and high-content imaging. Kampmann explains: "For CRISPRi, we target a transcriptional repressor domain (the KRAB domain) to the transcription start site of genes to repress their expression.
CRISPRi and CRISPRa Screens in Mammalian Cells for Precision Biology and Medicine Next-generation DNA sequencing technologies have led to a massive accumulation of genomic and transcriptomic data from patients and healthy individuals.
Such neurons are powerful tools to study cellular mech-anisms of neurodegenerative diseases. iPSCs 2020-10-20 · Kampmann used the technique to understand which genes are essential for neurons to survive and deal with stress. He and his colleagues used CRISPRi to systematically screen through and switch off each of approximately 20,000 genes encoding proteins in human stem cells that they then spurred to develop into neurons. CRISPRi/a can also be used to model and functionally evaluate disease-associated changes in gene expression, Dr. Kampmann is an associate professor at the University of California, Previously, Kampmann lab developed a strategy to control specific knockdown of genes (CRISPRi) in human neurons (Tian et al., 2019), now they expand this toolkit to control specific gene activation (CRISPRa). In this preprint, they perform a genome-wide CRISPRi and CRIPRa screen to identify genes important for neuronal survival. 2014-10-23 · High-Throughput Pooled CRISPRi/a Screening Two biological replicates of each screen were performed. From this data, we quantified the frequencies of cells expressing different sgRNAs in each sample and quantified the phenotype of each sgRNA, which we have previously defined for growth (γ) or resistance to treatment (ρ) ( Kampmann et al., 2013 ).

2018-04-13 · CRISPRi and CRISPRa: New Functional Genomics Tools Provide Complementary Insights into Cancer Biology and Therapeutic Strategies Martin Kampmann, Ph.D. Examples of cancer cell vulnerabilities include driver oncogenes that are essential for the initiation and progression of cancer, or non-oncogene addictions resulting from the cancerous state of the cell. 2020-03-19 · In a project led by postdoc Xiaoyan Guo in the Kampmann lab, a CRISPRi-based genetic screen uncovered the molecular mechanism by which mitochondrial dysfunction is relayed to the rest of the cell. The mitochondrial protease OMA1 cleaves a previously little characterized protein, DELE1. Previously, Kampmann lab developed a strategy to control specific knockdown of genes (CRISPRi) in human neurons (Tian et al., 2019), now they expand this toolkit to control specific gene activation (CRISPRa). In this preprint, they perform a genome-wide CRISPRi and CRIPRa screen to identify genes important for neuronal survival.

In CRISPRi, Kampmann and his colleagues figured out a way to disable the scissors protein, Cas9, and attach instead a protein that blocks normal gene activity. The end result is a modified CRISPR that dampens gene activity without editing the DNA itself.
