Our new preprint on DUSP4 in cancer is out. In vivo ARTi studies show DUSP4 loss doesn’t cause tumor regression and triggers fast compensatory reactivation. These results challenge DUSP4 as a monotherapy target. Link to preprint: www.biorxiv.org/content/10.6...
DUSP4 knockdown in BRAF V600E mutant colorectal cancer induces cell cycle arrest and halts tumor growth
Oncogenic signaling in cancer cells is essential for proliferation, and its disruption, either through inhibition or overactivation, can provide therapeutic opportunities. Dual specificity phosphatase 4 (DUSP4), a negative regulator of the MAPK pathway that dephosphorylates ERK, has been proposed as a potential target; however, its therapeutic relevance has not been evaluated in vivo. In this study, we show that DUSP4 knock-down induces G1 cell cycle arrest and reduces proliferation in BRAFV600E-mutant and BRAF inhibitor-resistant colorectal cancer models, both in vitro and in vivo, and induces a rapid DUSP5-mediated adaptive response. While treatment achieved tumor stasis indicating disease control, it did not yield tumor regression, suggesting that DUSP4 may have limited efficacy as a monotherapy target in cancer. ### Competing Interest Statement All authors are full time employees at Boehringer Ingelheim RCV.
