ADCYAP1R1 and spindle cell hemangioma: The nuclei with intense Adcyap1 expression mentioned above also had intense expression of Adcyap1r1. In addition, the PVH (49), SO (51), SCH (50), DMH (52a), arcuate hypothalamic, anterior hypothalamic nucleus, zona incerta (102, Figure 1—source data 1H), postero-lateral hypothalamic area (LH, area 74), periventricular hypothalamic nucleus posterior, dorsal premammillary nucleus and supramammillary nucleus medial (Figure 1—source data 1I and I10) exhibited strong Adcyap1r1 expression.
