The study found that the plasma circHECW2 level in MDD patients was significantly increased and was positively correlated with depression severity and anxiety symptoms
DUBs are classified into five major categories: ubiquitin carboxyl-terminal hydrolases, ubiquitin-specific proteases, metalloproteases, OTU domain-containing DUBs, and JAMM domain-containing DUBs [118]
