Moreover, no statistical differences were observed among the tissues (healthy, non-cancerous, vs tumor-caspase-4 + and caspase-4 -) about the contents of succinic acid (Figure 4A), oleic acid (Figure 4B), myristic acid (Figure 4C), linoleic acid (Figure 4D) and arachidic acid (Figure 4E), but not of arachidonic acid (Figure 4F). This evidence concerns the gene CASP4 and neoplasm.
