David Kramer kirjoittaa kurkumiinista seuraavaa:
Sitä ehdotetaan käytettäväksi AD sairautta vastaan. Eräs tutkimus oli havainnut, että kurkumiiniseos on vaikutukseltaan anti-amyloidogeeninen ja moduloi BACE1 ja APP proteiineja. APP on beta-amyloidin edeltäjäproteiini., josta voi haitallinen Abeeta muoto kehittyä silloin kun BACE1 entsyymi ja gammasekretaasi käyvät sitä pilkkomaan.

Aihepiiri Alzheimer's Disease. beta-Amylase ELISA kit: Current study suggest curcumin for Alzheimer's disease treatment
The authors of a recent study used an Abeta ELISA Kit that is available at antibodies-online. The published study shows that some curcumin mixes have a potent anti-amyloidogenic effect via modulation of BACE1 and APP and hence may be promising for AD treatment and prevention. There is evidence that a hallmark of Alzheimer's disease (AD) is the accumulation of beta-amyloid protein (Abeta). Abeta is generated from the beta-amyloid precursor protein (APP) through the proteolysis of beta-site APP cleaving enzyme 1 (BACE1) and gamma-secretase.

Curcumin mix has potent anti-amyloidogenic effect and shows great promise for AD treatment and prevention. The present study was conducted to examine the effects of curcumin mix and its different curcuminoids including curcumin (Cur), demethoxycurcumin (DMC) and bisdemethoxycurcumin (BDMC) on Aβ42, APP and BACE1.
We found that Cur was the most active curcuminoid fraction in suppressing Aβ42 production and the order of inhibitory potency of other curcuminoids was DMC > curcumin mix > BDMC. Cur, but not other curcuminoids, could reduce APP protein expression and none of curcuminoids affected APP mRNA level. BDMC could reduce BACE1 mRNA and protein levels, while DMC only affected BACE1 mRNA expression.
Our data indicate that the anti-amyloidogenic effect of Cur may be mediated through the modulation of APP, while the anti-amyloidogenic effect of BDMC may be mediated through the modulation of BACE1.

- Kurkumiini(Cur), mutta ei muut kurkuminoidit) vähensivät APP proteiinin ilmenemistä ja Abeetan tuottoa. Mikään kurkuminoidi ei voinut kuitenkaan vähentää APP mRNA:n ilmenemistä. BDMC vähensi pilkkovan entsyymin BACE1 mRNA:ta ja proteiinia. DMC vaikutti ainoastaan BACE1 mRNA expressioon.
We found that Cur was the most active curcuminoid fraction in suppressing Aβ42 production and the order of inhibitory potency of other curcuminoids was DMC > curcumin mix > BDMC. Cur, but not other curcuminoids, could reduce APP protein expression and none of curcuminoids affected APP mRNA level. BDMC could reduce BACE1 mRNA and protein levels, while DMC only affected BACE1 mRNA expression.
- Johtopäätöksenä kurkumiinin anti-amyloidogeeninen vaikutus välittyy APP modulaation kautta. BDMC:n antiamyloidogeeninen vaikutusvälittyy pilkkovan entsyymin BACE1 kautta.
Our data indicate that the anti-amyloidogenic effect of Cur may be mediated through the modulation of APP, while the anti-amyloidogenic effect of BDMC may be mediated through the modulation of BACE1.
