Kampmann is one of the co-developers of a modified CRISPR interference platform that addressed the problem of CRISPR-related toxicity in stem cells. CRISPR interference technology uses a

Many possibilities for parsing cancer emerge when labs combine gene editing and screens. And RNAi retains its spot in the menu of options.

CRISPRi and CRISPRa genetic screens in cells derived from human induced pluripotent stem cells (hiPSCs) can reveal mechanisms of disease-associated genes and of selective vulnerability of specific cell types. We use biochemistry, biophysics and cell biology to "zoom in" on individual nodes of the network and to reveal their mechanism of action. CRISPRbrain is an amazing resource for functional genomics screens in human cell types. This data commons is laying the #openscience foundation for a ton of high-throughput unbiased screens in the future.

CRISPRi-based loss-of-function screens and CRISPRa-based gain-of-function screens yield rich, complementary insights into cellular pathways. References: Gilbert LA, Horlbeck MA, Adamson B, Villalta JE, Chen Y, Whitehead EH, Guimaraes C, Panning B, Ploegh HL, Bassik MC, Qi LS, Kampmann M*, Weissman JS* (2014). CRISPR/Cas9-based functional genomics have transformed our ability to elucidate mammalian cell biology. However, most previous CRISPR-based screens were conducted in cancer cell lines rather than healthy, differentiated cells.

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 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. 2014-10-23 2019-10-03 2020-03-04 As a result, unlike standard CRISPR-Cas9, Kampmann predicted, CRISPRi shouldn't be toxic to iPSCs or stem cell-derived 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,

On Day 10, neurons were dissociated with Papain and approximately 98,000 CRISPRi neurons and 50,000 CRISPRa neurons were loaded into 10X chips with about 25,000 input cells per lane. M.

Next-generation DNA sequencing technologies have led to a massive accumulation of genomic and transcriptomic data from patients and healthy individuals. The major challenge ahead is to understand the functional significance of the elements of the human genome and transcriptome, and implications for diagnosis and treatment. Genetic screens in mammalian cells are a powerful approach to

The focus of this review is the use of CRISPR interference (CRISPRi) and CRISPR activation (CRISPRa) for genetic screens in mammalian cells. We introduce the underlying technology and present different types of CRISPRi/a screens, including those based on cell survival/proliferation, sensitivity to drugs or toxins, fluorescent reporters, and single-cell transcriptomes.
