DUBing Primary Tumors of the Central Nervous System: Regulatory Roles of Deubiquitinases

Blog Article

The ubiquitin proteasome system (UPS) utilizes an orchestrated enzymatic cascade of E1, E2, and E3 ligases to add single or multiple ubiquitin-like molecules as post-translational modification (PTM) to proteins.Ubiquitination can alter protein functions and/or mark ubiquitinated proteins for proteasomal degradation but deubiquitinases (DUBs) can reverse protein ubiquitination.While the importance of DUBs as regulatory factors in the UPS is undisputed, many questions remain on DUB selectivity for protein targeting, their mechanism of action, and the impact of DUBs on cottonmouth 3.5 high shirt the regulation of diverse biological processes.Furthermore, little is known about the expression and role of DUBs in tumors of the human central nervous system (CNS).

In this comprehensive review, we have used publicly available transcriptional datasets to determine the gene expression profiles of 99 ps5 price winnipeg deubiquitinases (DUBs) from five major DUB families in seven primary pediatric and adult CNS tumor entities.Our analysis identified selected DUBs as potential new functional players and biomarkers with prognostic value in specific subtypes of primary CNS tumors.Collectively, our analysis highlights an emerging role for DUBs in regulating CNS tumor cell biology and offers a rationale for future therapeutic targeting of DUBs in CNS tumors.
