Abstract:pathways, including purine and pyrimidine synthesis, were inhibited after JQ-1 treatment. Finally, real-time PCR showed that GART, TYMS, MTR and DHFR were upregulated after MTX treatment. However, these genes were downregulated after combination with JQ-1. Conclusion: Our results indicated that the combination of DHFR inhibitor MTX and BRD4/MYC inhibitor JQ-1 could induce synthetic lethality in pancreatic cancer both in vitro and in vivo, by disturbing nucleotide biosynthesis pathways. This study may provide u… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
