Summary of the differentially expressed PSA glycoforms in aggressive prostate cancer (PCa) blood serum samples.

PSA glycoforms were separated by SNA-chromatography and the percentage of the glycoforms was calculated. The reduction or increase (% change) of each glycoform was calculated by comparing the percentage of the PSA glycoforms from the six PCa blood serum samples with the one of standard PSA.

^aChanges in this PSA glycoform were only observed in group 1 pattern of the unbound PSA fractions of aggressive PCa samples.

^bThese PSA glycoforms were only present in group 2 pattern of the unbound PSA fractions of aggressive PCa samples.

^cThese PSA glycoforms were not present in any bound PSA fraction of aggressive PCa samples.
