WebThe data output is expressed as a fold-change or a fold-difference of expression levels. For example you might want to look at the change in expression of a particular gene over a given time period in a treated vs. untreated samples. WebFold change for each dose level from control. Profile: Pattern of response observed in the data over the different dose groups. "U" indicates up-regulation, and "D" indicates down-regulation. Each dose is compared to the previous dose. For example if you run a 4 dose study including "0" dose the profile of UUD indicates that the probe trend ...

Graphing data expressed as fold changes, or ratios. - FAQ

Fold change is a measure describing how much a quantity changes between an original and a subsequent measurement. It is defined as the ratio between the two quantities; for quantities A and B the fold change of B with respect to A is B/A. In other words, a change from 30 to 60 is defined as a fold-change of 2. This is also referred to as a "one fold increase". Similarly, a change from 30 to 15 is referred to as a "0.5-fold decrease".
