Drosophila melanogaster genotype-defined “3-hit” Egfr overexpression plus mutant p53 and Rbf suppression shows a kinase-modifier vulnerability where Pka-C3 strongly suppresses the phenotype.
- Why it matters: Muscle-invasive bladder cancer’s basal/squamous subtype often has elevated EGFR and TP53/RB1 alterations, but actionable functional vulnerabilities are not well defined.
- What they did: The authors built a Malpighian tubule 3-hit model and ran a dominant modifier screen across 216 kinase genes plus an RNA interference screen, then prioritized Pka-C3 (PRKX ortholog) using bladder tumor expression differences.
- The result: PRKX expression is higher in bladder tumors than normal tissue, and PRKX knockdown reduces spheroid volume in four bladder cancer cell lines, supporting PRKX as a candidate vulnerability.
