PSMD14 and neoplasm: New inhibitors such as Thiolatia (PSMD14 inhibitor) selectively inhibit the PSMD14 gene, which is highly expressed in many cancers, and its inhibition of key oncogenes ensures its efficacy in tumor metastasis; secondly, by virtue of its high specificity, it avoids the toxicity and side-effects of the traditional proteasome inhibitors; and the combination of the drug and cisplatin sensitization effect also gives it a wider scope of application.
