Prion Disease Induces Alzheimer Disease-Like Neuropathologic Changes.
San Francisco, United States. In J Neuropathol Exp Neurol, 29 Aug 2015
We next examined the CA1 region of the hippocampus from 14 patients with PrionD and found that 5 patients had low levels of scrapie-associated prion protein (PrP), many Aβ42 intraneuronal inclusions, low apolipoprotein E-4 (APOE-4), and no significant nerve cell loss.
Cholesterol and metal ions in Alzheimer's disease.
Ann Arbor, United States. In Chem Soc Rev, Nov 2014
For example, (a) cholesterol has been shown to be misregulated in AD-afflicted brains, and the aberrant activity of proteins (particularly, apolipoprotein E (ApoE) and 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase (HMGR)) has been linked to cholesterol-related AD exacerbation; (b) dyshomeostasis of metal ions associated with misfolded proteins (i.e., amyloid-β (Aβ) aggregates) found in the brains of AD patients is shown to promote oxidative stress leading to the malfunction of multiple proteins, including cytochrome c oxidase (CcO), and Cu/Zn superoxide dismutase (SOD1); (c) metal ion misregulation has also been observed to disrupt the activity of proteins (e.g., HMGR, low-density lipoproteins (LDL)), required for cholesterol production and regulation.

OBJECTIVE: We assessed four pharmacogenetic tests: 1) cytochrome P450, subfamily IIC, polypeptide 9 (CYP2C9), 2) vitamin K epoxide reductase subunit protein 1 (VKORC1), 3) apolipoprotein E (Apo E), and 4) methylenetetrahydrofolate reductase (MTHFR) for their associations with patient’s response to therapy with warfarin (CYP2C9 and VKORC1), statins (Apo E), or antifolate chemotherapy (MTHFR).
