Overexpression of ubiquitin carboxyl-terminal hydrolase 1 (UCHL1) in boys with cryptorchidism
BACKGROUND The ubiquitin-proteasome system regulate p53, caspase and Bcl-2 family proteins, and is crucial for the degradation of the defective germ cells in testes. Purpose: to evaluate the concentration of ubiquitin carboxyl-terminal hydrolase 1 (UCHL1) in the blood plasma of boys with cryptorchidism and if there is any correlation with patient age. METHODS Patients-50 boys aged 1-4 years (...
متن کاملOver-expression of ubiquitin carboxy terminal hydrolase-L1 induces apoptosis in breast cancer cells.
Ubiquitin carboxy terminal hydrolase-L1 (UCH-L1) belongs to the UCH proteases family that deubiquitinates ubiquitin-protein conjugates in the ubiquitin-proteasome system. Previous research showed that UCH-L1 was expressed in mouse retinal cells and testicular germ cells, and its function was associated with apoptosis. But it is still unclear whether UCH-L1 is concerned with apoptosis in tumor c...
متن کاملUbiquitin carboxyl-terminal hydrolase acts on ubiquitin carboxyl-terminal amides.
Ubiquitin carboxyl-terminal hydrolase (formerly known as ubiquitin carboxyl-terminal esterase), from rabbit reticulocytes, has been shown to hydrolyze thiol esters formed between the ubiquitin carboxyl terminus and small thiols (e.g. glutathione), as well as free ubiquitin adenylate (Rose, I. A., and Warms, J. V. B. (1983) Biochemistry 22, 4234-4237). We now show that this enzyme hydrolyzes ami...
متن کاملOverexpression of ubiquitin carboxyl-terminal hydrolase L1 (UCHL1) delays Alzheimer's progression in vivo
Deposition of amyloid β protein (Aβ) to form neuritic plaques in the brain is the pathological hallmark of Alzheimer's disease (AD). Aβ is produced by β- and γ-cleavages of amyloid β precursor protein (APP). Ubiquitin carboxyl-terminal hydrolase L1 (UCHL1) is a de-ubiquitinating enzyme that cleaves ubiquitin at its carboxyl terminal. Dysfunction of UCHL1 has been reported in neurodegenerative d...
متن کاملUbiquitin carboxy-terminal hydrolase L1 binds to and stabilizes monoubiquitin in neuron.
Mammalian neuronal cells abundantly express a deubiquitylating enzyme, ubiquitin carboxy-terminal hydrolase 1 (UCH L1). Mutations in UCH L1 are linked to Parkinson's disease as well as gracile axonal dystrophy (gad) in mice. In contrast to the UCH L3 isozyme that is universally expressed in all tissues, UCH L1 is expressed exclusively in neurons and testis/ovary. We found that UCH L1 associates...
