Growth hormone changes in HD subjects. Plasma BDNF, growth hormone (GH), Agouti-related protein (AgRP), and prolactin (PRL) were measured using the Millipore brain-derived protein panel. Data are mean ± s.e.m., n = 8–16. Statistical analysis was performed using One-Way ANOVA followed by Bonferroni's multiple-comparison test, p ≤ 0.05 (*, †, ‡, §) and p ≤ 0.01 (**, ††, ‡‡, §§) were considered statistically significant. * Represents significant difference against familial control; † represents significant difference against BLSA pre-manifest control; ‡ represents significant difference against BLSA manifest control and § represent significant difference against pre-manifest HD subjects. No change was found in BDNF levels (A). Reduction in GH was observed in manifest HD subjects (B). Elevation of AgRP was found in pre-manifest group (C). Reduction of PRL was observed in both pre- and manifest subjects (D).
