Figure S2 from CRISPR Screens Identify POLB as a Synthetic Lethal Enhancer of PARP Inhibition Exclusively in BRCA-Mutated Tumors

Key Points

• POLB knockout does not induce synthetic lethality in cancer cell lines, indicating specific target interactions.
• Viability was unaffected in POLB knockout cells, as shown by the CRISPR screening data from DepMap Public.
• The findings highlight the importance of genetic context, specifically in BRCA-mutated tumors when considering PARP inhibition.
• Research on POLB's role provides insights into cancer therapy strategies, emphasizing tailored approaches for different tumor types.
