Throughout the study a p-value of 0.05 in combination with a fold-change (FC) of 1.7 is applied as a threshold for calling a change in mRNA expression significant.The reported FC and p-value is based on the average of the four replicates versus the average of 200 wt profiles. Physically, DNA is wrapped around nucleosomes made of histones and further packaged into two types of chromatin: euchromatin, which is an active state and heterochromatin which is a repressed state, corresponding to on and off states controlling gene expression. We have found that, over time, genes are characterized by a limited number of chromatin states (combinations of histone modifications), and that, consistently, chromatin changes over genes tend to occur in a coordinated manner.
