Interestingly, we found six differentially abundant proteoforms to be statistically significant: Peptidyl-prolyl cis-trans isomerase A (PPIA), UDP-glucose 4-epimerase (GALE), septin-8 (SEPT8), Acetyl-CoA acetyltransferase, cytosolic (THIC/ACAT2), and Neutral alpha-glucosidase AB (GANAB) were inversely correlated, while Myeloid-derived growth factor (MYDGF) was positively correlated with the tumor size with a p-value < 0.05 (Figure 8). Here, GANAB is linked to neoplasm.
