The sample consisted of 20 OKCs, 20 ABs, and 10 AOTs. The Kruskal-Wallis, Mann-Whitney U, and Spearman\u2019s (r) tests were used for statistical analysis, with the level of significance set at 5% (p &lt; 0.05). The membrane\/cytoplasmic expression of SHH was significantly higher in AB compared to AOT (p = 0.022) and OKC (p = 0.02). No differences were found in the membrane\/cytoplasmic expression of SMO between the lesions studied. Regarding GLI-1, significant differences were observed at the nuclear level for AB and OKC compared to AOT (p &lt; 0.0001). In addition, significant positive correlations were found between cytoplasmic and nuclear GLI-1 in AB (r = 0.482; p = 0.031) and OKC (r = 0.865; p &lt; 0.0001), and between membrane\/cytoplasmic SMO and cytoplasmic GLI-1 in AOT (r = 0.667; p = 0.035) and OKC (r = 0.535; p = 0.015). The results of this study confirm the participation of the sonic hedgehog signaling pathway in the pathogenesis of the lesions studied. Overexpression of SHH in ABs and nuclear expression of GLI-1 in ABs and OKCs indicate that these proteins contribute to the more aggressive behavior of these two lesions when compared to AOT.<\/jats:p>","DOI":"10.1590\/0103-6440202204972","type":"journal-article","created":{"date-parts":[[2022,10,24]],"date-time":"2022-10-24T13:59:07Z","timestamp":1666619947000},"page":"91-99","source":"Crossref","is-referenced-by-count":7,"title":["Immunohistochemical
