T1 |
0-97 |
Sentence |
denotes |
ATP-binding cassette transporter A7 (ABCA7) loss of function alters Alzheimer amyloid processing. |
T2 |
98-260 |
Sentence |
denotes |
The ATP-binding cassette transporter A7 (ABCA7) has been identified as a susceptibility factor of late onset Alzheimer disease in genome-wide association studies. |
T3 |
261-338 |
Sentence |
denotes |
ABCA7 has been shown to mediate phagocytosis and affect membrane trafficking. |
T4 |
339-482 |
Sentence |
denotes |
The current study examined the impact of ABCA7 loss of function on amyloid precursor protein (APP) processing and generation of amyloid-β (Aβ). |
T5 |
483-606 |
Sentence |
denotes |
Suppression of endogenous ABCA7 in several different cell lines resulted in increased β-secretase cleavage and elevated Aβ. |
T6 |
607-704 |
Sentence |
denotes |
ABCA7 knock-out mice displayed an increased production of endogenous murine amyloid Aβ42 species. |
T7 |
705-873 |
Sentence |
denotes |
Crossing ABCA7-deficient animals to an APP transgenic model resulted in significant increases in the soluble Aβ as compared with mice expressing normal levels of ABCA7. |
T8 |
874-1068 |
Sentence |
denotes |
Only modest changes in the amount of insoluble Aβ and amyloid plaque densities were observed once the amyloid pathology was well developed, whereas Aβ deposition was enhanced in younger animals. |
T9 |
1069-1221 |
Sentence |
denotes |
In vitro studies indicated a more rapid endocytosis of APP in ABCA7 knock-out cells that is mechanistically consistent with the increased Aβ production. |
T10 |
1222-1403 |
Sentence |
denotes |
These in vitro and in vivo findings indicate a direct role of ABCA7 in amyloid processing that may be associated with its primary biological function to regulate endocytic pathways. |
T11 |
1404-1599 |
Sentence |
denotes |
Several potential loss-of-function ABCA7 mutations and deletions linked to Alzheimer disease that in some instances have a greater impact than apoE allelic variants have recently been identified. |
T12 |
1600-1791 |
Sentence |
denotes |
A reduction in ABCA7 expression or loss of function would be predicted to increase amyloid production and that may be a contributing factor in the associated Alzheimer disease susceptibility. |
