Expression profiles of the nitrergic signal marker protein neuronal nitric oxide synthase (nNOS) in male versus female rat VMN during eu- and hypoglycemia; impact of intracerebroventricular (icv) Lz infusion. Mean normalized rostral (a; F_(7,40) = 4.64; p = 0.001), middle (b; F_(7,40) = 7.86; p = 0.001), and caudal (c; F_(7,40) = 10.04; p < 0.0001) VMN nNOS protein O.D. values ± S.E.M. are presented for V/V, V/INS, Lz/V, and Lz/INS groups of male (M; left-hand side) and female (F; right-hand side) rats; n = 6 animals per group. *p < 0.05; **p < 0.01; ***p < 0.001; ****p < 0.0001. Results are summarized in the table at bottom; ↑ and ↓ denote a relative increase or decrease, respectively, between treatment groups; no change (NC) between groups is also indicated
