  1. Genes that were up-regulated, down-regulated, and exhibited no significant change in expression are indicated by the symbols “+”, “−” and “=”, respectively. Changes in an individual gene’s expression are denoted in the format [a/b], where a is the symbol indicating the change between C1 and D1, and b is the symbol indicating the change between D1 and D2. Thus, for example, a gene of the [+/+] type was up-regulated between C1 and D1, and also between D1 and D2, whereas a gene of the [=/+] type exhibited no change in expression between C1 and D1, but was up-regulated between D1 and D2
