The threshold with FC>0.5 and p<0.05 was used to determine differentially expressed molecules.
Category of related biofunctions.
The probability that the association between a set of genes in the dataset and a related function is due to random association.
The z-score predicts the direction of change for the function. A positive z-score indicates increased function and negative z-score indicates reduced function. An absolute z-score of ≥2 is considered significant.
