CRISPRi/a functional screen with PARP7 inhibitor in NCI-H1373 cells

Project description:PARP7 is a monoPARP that catalyzes the transfer of single units of ADP-ribose onto substrates to change their function. PARP7 expression is increased by aromatic hydrocarbons and cellular stress, and the PARP7 gene is amplified in cancers, especially in those of the upper aerodigestive tract. PARP7 is a negative regulator of nucleic acid sensing in tumor cells. Inhibition of PARP7 restores Type I IFN signaling responses to nucleic acids in tumor models. Restored signaling can directly inhibit cell proliferation and activate the immune system, both of which contribute to tumor regression. RBN-2397 is a potent and selective inhibitor of PARP7. To further explore how RBN-2397 inhibits NCI-H1373 cell proliferation, we performed unbiased genetic screens using whole-genome CRISPRi and CRISPRa libraries (le Sage et al., 2017; Jost and Weissman, 2018). Comparison of CRISPRi and CRISPRa phenotype scores highlights genes with opposing functionality upon RBN-2397 treatment.

Transcriptional changes by PARP7 inhibitor in cancer cell lines

Project description:PARP7 is a monoPARP that catalyzes the transfer of single units of ADP-ribose onto substrates to change their function. PARP7 expression is increased by aromatic hydrocarbons and cellular stress, and the PARP7 gene is amplified in cancers, especially in those of the upper aerodigestive tract.

Restored signaling can directly inhibit cell proliferation and activate the immune system, both of which contribute to tumor regression. RBN-2397 is a potent and selective inhibitor of PARP7. To further investigate the mechanism of action of RBN-2397 and identify potential biomarkers we investigated transcriptional changes after RBN-2397 treatment in two PARP7 inhibitor sensitive cell lines, NCI-H1373 and NCI-H647, by RNA sequencing.

A whole genome CRISPR screen identifies AHR loss as a mechanism of resistance to a PARP7 inhibitor

Project description:Inhibitors directed towards PARP1 and PARP2 are approved agents for the treatment of BRCA-related cancers. Other members of the PARP family have also been implicated in cancer and are being assessed as therapeutic targets in cancer and other diseases. In fact, an inhibitor of PARP7 (RBN-2397) has now reached early-stage human clinical trials. Here, we performed a genome-wide CRISPR screen for genes that modify the response of cells to RBN-2397. We identify the polycyclic aromatic hydrocarbon receptor AHR and multiple components of the cohesin complex as determinants of resistance to this agent. Activators and inhibitors of AHR modulate the cellular response to PARP7 inhibition, suggesting potential combination therapy approaches.

Transcriptional changes by RBN-2397 treatment and FRA1 knockdown in NCI-H1975 cells

Project description:PARP7 inhibitors reduce tumor growth in a cell-autonomous manner and by enhancing immune recognition through restoring nucleic acid (NA)-sensing-dependent innate immune signaling. However, the molecular targets of PARP7-mediated ADP-ribosylation, regulating cell survival and innate immune signaling, remained elusive. Here, we identified PARP7 as a nuclear and cysteine-specific mono-ART that ADP-ribosylates proteins critical for regulating gene expression, such as the AP-1 transcription factor FRA1. Upon PARP7 inhibition the loss of FRA1 ADP-ribosylation increased FRA1 degradation in a PSMC3 and proteasomal-dependent manner. To further investigate how FRA1 promotes cell survival, we investigated transcriptional changes after RBN-2397 treatment and FRA1 knockdown in the PARP7 inhibitor sensitive cell line NCI-H1975 by RNA sequencing.
