Genetic rearrangements, hotspot mutations, and microRNA expression in the progression of metastatic adenoid cystic carcinoma of the salivary gland

Adenoid cystic carcinoma (ACC) is a common salivary gland malignancy. The malignancy is associated with gene fusions between MYB, MYBL1, and NFIB. FISH analysis was used to evaluate any rearrangements in these genes with the use of our break apart probes. It was found through FISH that MYB aberrations were preserved between primary tumors and metastases. Additionally, MYB and NFIB aberrations are preserved in ACC metastatic lesions.

Recurrent rearrangements of the PLAG1 and HMGA2 genes in lacrimal gland pleomorphic adenoma and carcinoma ex pleomorphic adenoma

Lacrimal gland tumors are histologically similar to salivary gland tumors. In the salivary glands, pleomorphic adenoma (PA) and carcinoma ex pleomorphic adenoma (ca_ex_PA) are both characterized by PLAG1 and HMGA2 gene rearrangements. However, it is not known if these rearrangements are present in lacrimal gland PA and ca_ex_PA. FISH analysis was done with our PLAG1, HMGA2, and NFIB break apart probes. It was found that rearrangements were frequent in the tested lacrimal glands and that testing for the rearrangement can help in distinguishing lacrimal gland PA and ca_ex_PA from de novo carcinomas.

MicroRNA dysregulation in adenoid cystic carcinoma of the salivary gland in relation to prognosis and gene fusion status: a cohort study

Adenoid cystic carcinoma (ACC) is a frequent malignancy of the salivary gland that is challenging due to an unpredictable clinical course. In hopes of improving this predictability, the association of microRNA with prognostic value in ACC is under study. Along with microRNA tests, FISH analysis was performed with various break apart probes, including our MYLB1 and NFIB probes, to look for any fusion or rearrangement. It was found that several microRNAs were associated with the outcome of ACC and that the most unifying feature of ACC is still involvement of the MYB gene.

Molecular features of adenoid cystic carcinoma with an emphasis on microRNA expression

Adenoid cystic carcinoma (ACC) is a subtype of salivary gland tumor that can have a poor prognosis. ACC can also be present in lacrimal glands and the breasts with the tumors appearing to be seemingly identical to one another. The phenotypes, genetics, and microRNA expression of ACC in the salivary glands, lacrimal glands, and breasts was characterized in order to better understand the differences between them. Among other characterization tools, FISH analysis was performed with several break apart probes, including our MYBL1 and NFIB probes. The results seemed to indicate that microRNA has value in distinguishing between the tumors.
