Adenoid Cystic Carcinoma of the Lacrimal Gland: MYB Gene Activation, Genomic Imbalances, and Clinical Characteristics – Corrected Proof
Purpose: To investigate genetic alterations in lacrimal gland adenoid cystic carcinomas (ACCs) with emphasis on the MYB-NFIB fusion oncogene and its downstream targets, MYB rearrangements, and copy number alterations in relation to clinical data and survival.Design: Experimental study.Participants and Controls: Fourteen patients with primary lacrimal gland ACC were included. As a control, we also studied the expression of MYB-NFIB in 19 non-ACC lacrimal gland tumors.Methods: The expression and identity of MYB-NFIB fusion transcripts were studied using reverse transcriptase polymerase chain reaction (RT-PCR) and nucleotide sequence analyses. Quantitative polymerase chain reaction (PCR) and immunohistochemistry were used to evaluate the expression of (Read more...)
