Fig. 4From: Orotic acid-treated hepatocellular carcinoma cells resist steatosis by modification of fatty acid metabolismDiscriminant analyses of FA results. Discriminant analyses depicting the classification of fatty acid signatures of HepG2 cells and culture media in the different treatment groups based on discriminant functions 1 and 2. a represents all samples, b represents HepG2 cells and c all media, while in d raw medium is excluded. Note that the scaling varies between panels in the x- and y-axes. With the first two functions, 97.1% of the variance was explained in panel a, 95.2% in panel b, 99.6% in panel c and 91.1% in panel d.
