HOXB9 Expression Correlates with Histological Grade and Prognosis in LSCC

Area of Science:

• Oncology
• Molecular Biology
• Genetics

Background:

• Laryngeal squamous cell carcinoma (LSCC) is a significant global health concern.
• Understanding the molecular mechanisms underlying LSCC development and progression is crucial for improving patient outcomes.

Purpose of the Study:

• To investigate the HOX gene expression profile in LSCC tissues.
• To determine the association between specific HOX gene expression and clinicopathological features and prognosis in LSCC patients.

Main Methods:

• HOX gene expression was analyzed using microarray technology in paired LSCC and adjacent noncancerous tissues.
• Quantitative real-time PCR (qRT-PCR) was employed for validation.
• Tissue microarray (TMA) analysis was performed for HOXB9, HOXB13, and HOXD13.
• Correlation analyses were conducted between gene expression levels and clinicopathological parameters and patient prognosis.

Main Results:

• Microarray analysis identified 15 upregulated and 2 downregulated HOX genes in LSCC.
• HOXB9, HOXB13, and HOXD13 showed significantly increased expression in LSCC tissues compared to noncancerous tissues (P < 0.001).
• HOXB9 expression correlated significantly with histological grade (P < 0.01) and poorer prognosis (P < 0.01) in LSCC patients.

Conclusions:

• HOXB9, HOXB13, and HOXD13 are upregulated in LSCC and may play critical roles in its pathogenesis.
• HOXB9 emerges as a potential novel biomarker for predicting poor prognosis in LSCC.
• Targeting HOXB9 may offer a potential therapeutic strategy for LSCC treatment.
