Ubiquitin-Specific Proteases in Breast Cancer: Unraveling Oncogenic Roles and Therapeutic Opportunities. (PubMed, DNA Cell Biol)
Pharmacological inhibitors of specific USPs, such as pimozide, trifluoperazine, rottlerin, 6-thioguanine, and costunolide, are highlighted for their potential to inhibit proliferation, metastasis, induce apoptosis, and circumvent therapy resistance across breast cancer subtypes (triple-negative and HER-2 positive). The review highlights the complex and often contradictory roles of USPs in breast cancer and points to the immense promise of targeting these enzymes to develop new and efficacious anticancer therapies.

Placing purines in precision medicine: Targeting a metabolic reliance in KRAS-mutant tumors. (PubMed, iScience)
In KRAS-mutant cancer models, trametinib treatment caused dysregulation of the purine biosynthetic pathway driven by reductions in enzyme GART. This induced vulnerability nominated purine analog 6-thioguanine as a synergistic partner...In vivo, the treatment significantly increases overall survival without systemic toxicity. Integrating drug-induced multi-omic changes with functional screening identifies therapeutic strategies, supporting the use of purine analogs with MEK inhibitors for KRAS-mutant tumors.
