The long noncoding RNA KIAA0125 is upregulated in ameloblastomas

Area of Science:

• Oral pathology
• Molecular oncology
• Genomics

Background:

• Ameloblastoma and adenomatoid odontogenic tumor (AOT) are jaw neoplasms originating from the tooth-forming apparatus.
• Ameloblastoma is characterized by aggressive growth and potential for facial deformity, while AOT exhibits indolent behavior.
• The molecular underpinnings of these distinct behaviors remain largely unexplored.

Purpose of the Study:

• To investigate the expression profile of the long noncoding RNA (lncRNA) KIAA0125 in ameloblastoma and AOT.
• To explore the potential role of KIAA0125 in the pathobiology of these odontogenic tumors.
• To identify potential therapeutic targets for ameloblastoma.

Main Methods:

• Utilized quantitative real-time PCR (qPCR) to measure KIAA0125 transcript levels in tumor samples and dental follicles.
• Included thirteen samples: five solid/multicystic ameloblastomas, four AOTs, and four dental follicles.
• Employed in silico prediction to identify microRNA (miRNA) families interacting with KIAA0125.

Main Results:

• KIAA0125 expression was significantly higher in ameloblastoma samples compared to dental follicles (p=0.042).
• No significant difference in KIAA0125 expression was observed between AOT and dental follicles.
• In silico analysis predicted interactions between KIAA0125 and 41 miRNA families, including four previously implicated in ameloblastoma.

Conclusions:

• The lncRNA KIAA0125 is likely implicated in the pathobiology of ameloblastoma.
• KIAA0125 may serve as a potential diagnostic marker or therapeutic target for ameloblastoma.
• Further experimental validation of KIAA0125 functions could lead to targeted therapies for extensive and recurrent ameloblastoma cases.
