Fig. 4. CG8422 transcripts are consistently detected in adult head RNA. Data mined from microarray results that were described by Lin et al. (2002) using adult head RNA from the genotypes and environmental conditions listed in the text. L:D, 12 h:12 h light:dark; D:D, constant darkness. Values are medians + median average deviation (M.A.D.). Values within bars represent the number of microarrays. CG8422 levels were not significantly different in WT (wild type) L:D versus WT D:D (P=0.28), in per (period mutant) L:D versus per D:D (P=0.25), in WT L:D versus per L:D (P=0.33) or in WT D:D versus per D:D (P=0.06), as indicated by the Mann-Whitney U test.
