Fig. 3.

This figure shows (A) representative autoradiograms and (B) quantification of prepro-CRH mRNA expression in the paraventricular hypothalamic nucleus for C57Bl/6N mice fed either the control diet (control; n = 10), the Mg²⁺ deficient diet (MgD; n = 10), or the Mg²⁺ deficient diet after long-term treatment with desipramine (MgD + DMI; n = 10); it also provides quantification of unspecific hybridisation. Data represent mean ± SEM. *P < 0.05, ***P < 0.001 for Mg²⁺ deficient vs. control mice and ^###P < 0.001 for desipramine-treated Mg²⁺ deficient mice vs. Mg²⁺ deficient mice.
