Figure 6: Leptin effect on Icer mRNA expression in cultured rat pineal gland. The glands were challenged with leptin (Lep 1 nM) associated with norepinephrine (NE 1 μM). One-way ANOVA, followed by Bonferroni’s post hoc test. versus control, versus NE 1 μM. Data are reported as the number of transcripts per number of ribosomal protein L37a (Rpl37a) molecules. glands/group and each experiment was repeated 3 times.
