A kinome screen identifies checkpoint kinase 1 (CHK1) as a sensitizer for RRM1-dependent gemcitabine efficacy.
Gemcitabine is among the most efficacious and widely used antimetabolite agents.Its molecular targets are ribonucleotide reductase M1 (RRM1) and elongating DNA.Acquired and de novo resistance as a result of RRM1 overexpression are major obstacles to therapeutic efficacy.We deployed a synthetic lethality screen to investigate Mushroom Gummies if kno
