18. The presence of USP8 mutations may predict favorable responses to the somatostatin analog pasireotide in corticotroph adenomas of Cushing's disease. PMID: 26578638
19. The identification of USP8 mutations as contributors to the pathogenesis of ACTH-secreting pituitary adenomas represents an exciting advance in our understanding of Cushing's disease and its potential treatment into the of precision medicine. PMID: 25930709
20. these findings implicate a novel role for K6-linked Ub conjugates and USP8-mediated deubiquitination in the regulation of PARK2 in mitochondrial quality control PMID: 25700639
21. In surgically resected primary USP8-mutated tumor cells, USP8 knockdown or blocking EGFR effectively attenuates ACTH secretion. Inhibition of USP8 or EGFR is promising for treating USP8-mutated corticotrophin adenoma. PMID: 25675982
22. USP8 is frequently mutated in adenomas causing Cushing's disease, especially in those from female adult patients diagnosed at a younger age. PMID: 25942478
23. Haplotype CAAG may be a down-regulating factor for the risk of non-obstructive azoospermia. PMID: 25863102
24. BRUCE acts as a scaffold, bridging the ubiquitin-specific peptidase 8 (USP8) and BRIT1 in a complex to coordinate USP8-catalyzed deubiquitination of BRIT1. PMID: 25733871
25. USP8 is required for ci-M6PR endosomal localisation. PMID: 24894536
26. Somatic USP8 mutations in corticotroph adenomas clustered in the 14-3-3 protein binding motif and enhanced catalysis and proteolytic cleavage, which increased EGF receptor deubiqutination and signaling. USP8 mutants enhanced POMC promoter activity. PMID: 25485838
