Identification of new genes of pleomorphic adenoma.

Abstract

Pleomorphic adenoma is the most common salivary gland neoplasm with a variety of histologic appearances. Due to this diversity, precise preoperative diagnosis through fine needle aspiration cytology is difficult.This study sought to identify the differentially expressed genes in pleomorphic adenoma to aid precise diagnosis and clarify the mechanism of tumorigenesis.Suppressive subtractive hybridization was performed on pleomorphic adenoma tissues and the corresponding normal salivary gland tissues to screen of the differential expression of genes in pleomorphic adenoma.Four known genes (microfibrillar associated protein 4 [MFAP4], dystonin [DST], solute carrier family 35 [SLC35], and potassium channel tetramerization domain containing 15 [KCTD15]) were differentially expressed in the tumors compared with the genes in normal tissues. The expression profiles were further confirmed in 15 pleomorphic adenoma and corresponding normal salivary gland tissues by quantitative real-time reverse transcription-polymerase chain reaction.MFAP4, DST, SLC35, and KCTD15 gene expression could be potential biomarkers of pleomorphic adenoma for precise diagnosis.
