2019-10-23 · CRISPRn and CRISPRi screening platforms each have their advantages for specific applications (Kampmann, 2018, Rosenbluh et al., 2017) but generally yield similar results (Horlbeck et al., 2016). Most previous CRISPR-based screens were implemented in cancer cell lines or stem cells rather than healthy differentiated human cells, thereby limiting potential insights into cell-type-specific roles

(D) CRISPRi activity for all 49 genes in deﬁned windows relative to the TSS of each gene. (E) Ricin-resistance phenotypes, comparing CRISPRi sgRNAs selected by our rules to RNAi, for genes previously established to cause ricin-resistance phe-notypes when knocked down by RNAi.

Cells are screened by using microscopy and classified by artificial intelligence (AI) algorithms, which precisely identify the genetically altered phenotype. San Francisco, CA — A team of scientists at UC San Francisco and the National Institutes of Health have achieved another CRISPR first, one which may fundamentally alter the way scientists study brain diseases. In a paper published August 15 in the journal Neuron, the researchers describe a technique that uses a special version of CRISPR developed at UCSF to systematically alter the activity As a result, unlike standard CRISPR-Cas9, Kampmann predicted, CRISPRi shouldn't be toxic to iPSCs or stem cell-derived neurons. In the new paper, Kampmann and his collaborators describe how they adapted CRISPRi for use in human iPSCs and iPSC-derived neurons, and found that it could target and interfere with genes without killing the cell -- a feat that had long eluded scientists.

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. Martin KAMPMANN, Assistant Professor of University of California, San Francisco CRISPRi has minimal impact on ATP levels under basal conditions during which both respiration and glycolysis are 2019-08-15 Martin KAMPMANN, Assistant Professor | Cited by 3,206 | of University of California, San Francisco, CA (UCSF) | Read 139 publications | Contact Martin KAMPMANN While the catalog of mammalian transcripts and their expression levels in different cell types and disease states is rapidly expanding, our understanding of transcript function lags behind.

2021-04-08 · Focusing on lipid oxidation, Kampmann's group next employed CRISPRi screens to hunt for genes that influenced levels of ROS or peroxidized lipids. Here, they found many expected genes, such as those involved in electron transport or autophagy—pathways that can cause and curtail oxidative stress, respectively.

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.

A major barrier to developing effective therapies for neurodegenerative diseases is our incomplete understanding of the underlying cellular mechanisms. Genetic screens in human-induced pluripotent stem cell-derived neurons can elucidate such mechanisms. Genome-wide screens using CRISPR interference …

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 ).
