In recent years, the AAA+ ATPase family members Pontin (RuvBL1, Tip49a) and Reptin (RuvBL2, Tip49b) have been implicated in various processes, including transcription regulation, chromatin remodeling and DNA damage repair, that are frequently deregulated in cancer.

Abstract

Purpose Salivary gland cancer (SGC) is a rare and heterogeneous disease with significant differences in recurrence and metas- tasis characteristics. As yet, little is known about the mechanisms underlying the initiation and/or progression of these diverse tumors. In recent years, the AAA+ ATPase family members Pontin (RuvBL1, Tip49a) and Reptin (RuvBL2, Tip49b) have been implicated in various processes, including transcription regulation, chromatin remodeling and DNA damage repair, that are frequently deregulated in cancer. The aim of this study was to assess the clinical and functional significance of Reptin and Pontin expression in SGC. Methods Immunohistochemical staining of Pontin, Reptin, β-catenin, Cyclin D1, TP53 and MIB-1 was performed on a collec- tion of 94 SGC tumor samples comprising 13 different histological subtypes using tissue microarrays. Results We found that Reptin and Pontin were expressed in the majority of SGC samples across all histological subtypes. Patients with a high Reptin expression showed a significantly inferior 5-year overall survival rate compared to patients with a low Reptin expression (47.7% versus 78.3%; p = 0.033), whereas no such difference was observed for Pontin.
