Figure 5.
The effect of HFD and oral MJ extract on heme oxygenase 1 expression. Heme oxygenase 1 (HO-1), a marker of antioxidative expression, within the cavernosa was determined by immunohistochemistry. Top panel: A: Control NCD; B: NCD + MJ; C: NCD + THC; Middle panel: D: Control HFD; E: HFD + MJ; F: HFD + THC. Bottom panel: QIA evaluation as %HO-1 cells/total cells means ± SEM. HO-1 expression was significantly reduced in the corpora of HFD + MJ group compared to the control NCD or HFD group (∗∗∗P < .001, ∗∗P < .01 respectively). A reduction in HO-1 expression was also seen in NCD + THC vs control NCD and HFD + THC vs control HFD (∗P < .05). Magnification = 100×; 1 bar = 100 μm.
