Fig. 4 Assay for rhythmic Expression of lypge. (A–D) Expression is examined by qRT-PCR in different light-dark cycles (A: LD, B: DL, C: LL, D: DD). White and gray backgrounds represent light and dark phases. Zebrafish larvae were collected at two time points per day between 2 and 6 dpf. Embryos were sampled at zeitgeber time (ZT) 3 and 15. Statistically significant differences between the expression peak and through on each day (Fisher's t-test) are indicated:*P < 0.05, **P < 0.01, ***P < 0.001. Error bars indicate s.e.m. (E) Embryos are expose to continuous light or dark after 48 hpf and its expression in pineal gland is detected at different time.
