From: Clock mutation affects circadian regulation of circulating blood cells
Circadian variations in peripheral circulating redblood cells (RBC) in Clock mutant mice. (A) Number of RBC and (B) blood levels of hemoglobin (HGB). Open and filled circles, values from wild-type and Clock mutant mice, respectively. Open and solid bars represent lights on and off, respectively. Values represent means ± SEM (n = 3). **P < 0.01, significant difference between genotypes.
