Using this information we increased the density of markers in each QTL region (MMU1, 2, 5, 8, 9, 11 and 17; Table 1 and Additional File 1), ensuring the absence of CAST alleles at each of these QTL.

To ensure that Aβ production was suppressed in concert with the dox-mediated inhibition of its precursor APPswe/ind, we measured Aβ40 and Aβ42 levels by ELISA in forebrain homogenates from young tet-off animals.

However, in the current study, we feel that although the poor performance of the tTA/APP mice in the maze tests could technically be scored as cognitive impairment, the animals' severe hyperactivity made interpretation of the cognitive tasks impossible.
