The role of ADAM10 and ADAM17 in the ectodomain shedding of angiotensin converting enzyme and the amyloid precursor protein

Topic: Disease mechanisms in lab and animal studies
Numerous transmembrane proteins, including the blood pressure regulating angiotensin converting enzyme (ACE) and the Alzheimer's disease amyloid precursor protein (APP), are proteolytically shed from the plasma membrane by metalloproteases. We have used an antisense oligonucleotide (ASO) approach to delineate the role of ADAM10 and tumour necrosis factor-alpha converting enzyme (TACE; ADAM17) in the ectodomain shedding of ACE and APP from human SH-SY5Y cells. Although the ADAM10 ASO and TACE ASO significantly reduced (> 81%) their respective mRNA levels and reduced the alpha-secretase shedding of APP by 60% and 30%, respectively, neither ASO reduced the shedding of ACE. The mercurial compound 4-aminophenylmercuric acetate (APMA) stimulated the shedding of ACE but not of APP. The APMA-stimulated secretase cleaved ACE at the same Arg-Ser bond in the juxtamembrane stalk as the constitutive secretase but was more sensitive to inhibition by a hydroxamate-based compound. The APMA-activated shedding of ACE was not reduced by the ADAM10 or TACE ASOs. These results indicate that neither ADAM10 nor TACE are involved in the shedding of ACE and that APMA, which activates a distinct ACE secretase, is the first pharmacological agent to distinguish between the shedding of ACE and APP.
Key findings
- Although the ADAM10 ASO and TACE ASO significantly reduced (> 81%) their respective mRNA levels and reduced the alpha-secretase shedding of APP by 60% and 30%, respectively, neither ASO reduced the shedding of ACE.
- These results indicate that neither ADAM10 nor TACE are involved in the shedding of ACE and that APMA, which activates a distinct ACE secretase, is the first pharmacological agent to distinguish between the shedding of ACE and APP.

How this study scored 36/100
Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported, studied in people and randomised / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multi-centre collaboration, so those were left out: it earned 21 of the 58 points we could judge it on, which is 36 out of 100.
