| Background: Lung cancer is one of the most common types of fatal malignancies. Despite the remarkable advances
in diagnosis and treatment approaches, most of the cases detected in the late stages. Discovering novel markers to
recognizing cancer in early stages requires a deep understanding of molecular mechanisms. OSBPL3, the molecule
belongs to the oxysterol-binding proteins (OSBP) family, involved in lipid metabolism and sterol transport;
however, recent evidence considers the role of members of this family in cancer pathogenesis. We aimed to
investigate the expression level of OSBPL3 in the tumor tissues of NSCLC patients.
Methods: By bronchoscopy procedure, 45 lung tissue samples including 25 cancerous and 20 non-cancerous
control lung tissues were collected. The total RNA of them was extracted and then cDNA synthesized. Assessment
of the OSBPL3 expression level was performed utilizing qRT-PCR.
Results: The significantly increased mRNA expression level of OSBPL3 was observed in NSCLC tissues compared to
the control of non-cancerous tissues (fold change = +2.38, P < 0.05). Moreover, ROC Curve analysis of this gene
showed that OSBPL3 is the potential gene to be used as a biomarker for NSCLC diagnosis.
Conclusion: Our data revealed the oncogenic function of OSBPL3 in NSCLC tissues. In case of confirmation of
future studies, the mRNA expression level of OSBPL3 can be used as a biomarker for NSCLC diagnosis. |
