Immunoexpression of biomarkers Bax, Bcl-2, CD-138, H3, Ki-67, MCM3 and p53 in oral lichen planus
2019
This study aims to establish an association of the expression of specific biomarkers in oral lichen planus to understand its biological behavior. Materials and methods: An immunohistochemistry study was conducted in 40 cases of oral lichen planus against BAX, BCL-2, CD138, Histone 3, Ki-67, MCM3 and p53 at the Molecular Pathology Area of the School of Dentistry, UDELAR, Uruguay. Results: A greater expression of BAX was detected compared to BCL-2, suggesting a pro-apoptotic behavior, supported by the absence of p53 expression. MCM3 expression was more sensitive than Ki-67, considering proliferation alterations. CD-138 had a more intense and uniform expression, determining fewer intercellular adhesion alterations. Conclusions: The expression of the proteins studied suggests an alteration in proliferative and apoptotic mechanisms, associated with a pathological behavior of the oral mucosa.
