HMGB1 and posterior cortical atrophy: Interestingly, 43% of detected HMGB1 interactome targets (10 of a total of 28, referenced in Table 1 and Table 3) as well as 64% of HMGB2 (7 of a total of 11, referenced in Table 2 and Table 4) have previously been related to PCa, supporting the functional significance of our Y2H interactome data in PCa research.
