Kampmann explains: "For CRISPRi, we target a transcriptional repressor domain (the KRAB domain) to the transcription start site of genes to repress their expression. This knockdown approach is highly effective and lacks the notorious off-target effects of RNAi-based gene knockdown."

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. 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 the new paper, Kampmann and his collaborators describe how they adapted CRISPRi for use in Martin KAMPMANN, Assistant Professor | Cited by 3,582 | of University of California, San Francisco, CA (UCSF) | Read 145 publications | Contact Martin KAMPMANN Second, as the secretory pathway is of critical importance for cell homeostasis and viability, gene expression was systematically down-regulated using the dCas9 fused to a KRAB effector domain for CRISPRi, instead of the active Cas9 for CRISPR knockout (Shalem et al., 2015; Kampmann, 2018). 2020-07-08 · Kampmann describes how new CRISPR-based functional genomics approaches can uncover disease Modelling of disease-associated changes in gene expression via CRISPRi and CRISPRa can pinpoint 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. 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. CRISPRi-based loss-of-function screens and CRISPRa-based gain-of-function screens yield rich, complementary insights into cellular pathways.

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. 2020-06-26 · Briefly, Day 0 CRISPRi and CRISPRa neurons were infected by the corresponding CROP-seq sgRNA library at a MOI of 0.1-0.2, followed by puromycin selection at 4 µg/ml for 3 days and recovery.

Genome-wide screens using CRISPR interference … Cancer cells commonly develop resistance to immunotherapy by loss of antigen expression. Combinatorial treatments that increase levels of the target antigen on the surface of cancer cells have the potential to restore efficacy to immunotherapy. Here, we use our CRISPR interference- and CRISPR activa …
