Example: "The alteration of the amount in the budget was necessary to accommodate unexpected expenses."
Alternatives: "change in the amount" or "modification of the amount".
As consequence, an alteration of the amount of MBP epitopes (e.g. MBP111 119) presented on dendritic cells due to the LMP2 polymorphism might affect the repertoire of MBP-reactive CD8+ T cells and, thereby their eventual activation during the early phases of MS onset.
Alteration of the amount of AR expressed did not affect the inhibition by C/EBPα either of the full-length PSA promoter/enhancer or the proximal PSA promoter.
Whether there is compensation by increased expression of other γ subunits such as the γ6 and γ7 subunits, which were shown recently to be present in skeletal muscle by RT-PCR [ 19], or alteration of the amount of the other subunits remains to be determined in the future.
Transfection of green fluorescent protein (GFP) specific siRNA served as an additional control and lead to no significant alterations of the amount of viable cells (data not shown).
This change in behaviour was not associated with an alteration to the amount of nocturnal sleep or locomotor activity (Fig. 2C, D & G), nor any change to the length of either daytime or nocturnal sleep bout length (Fig. 2E).
We then performed an electrophoretic mobility shift assay (EMSA) by using the probes labeled with P, and finally nine probes were confirmed to show the alterations of the amounts of protein-DNA complexes in R6/2 cortical lysates.
In both E13.5 PGCs and 3dpp sprmatogonia, expression levels of Gapdh were also comparable between DicerCKO and controls (Figure3D), demonstrating that results of retrotransposon expressions were not due to alteration in the amount of Gapdh transcript.
Even if bone mineral density is within the acceptable range, disruption of bone microarchitecture or alteration in the amount and variety of proteins in bone can still increase the risk of fractures (14).
This alteration affects the amount of IFT.
