Interestingly, 12 out of the 47 peptides selectively present in the non-CP EqMDEC CM have a known role as tumor suppressors (Table 2), and PANTHER gene ontology analysis showed that these peptides were most commonly associated with 3 main pathways, whereas peptides selectively found in CP EqMDEC CM had a much more diverse profile (Supplementary Fig. 2A). The gene discussed is CP; the disease is neoplasm.
