GFAP and mood disorder: In contrast, this reduction of GFAP mRNA expression level during daytime was absent in the mood disorder patients, comparing GFAP mRNA level from mood disorder patients with a clock time of death during daytime and those from the mood disorder patients with a clock time of death during nighttime (n = 6, 08:01–20:00 h vs. n = 7, 20:01–08:00 h; p = 0.775, Figure 1J).
