Micro RNA-148a Targets Bcl-2 in Patients with Non-Small Cell Lung Cancer.

Objective: Lung cancer is one of the most prevalent cancers and the leading cause of cancer-related deaths worldwide. MicroRNAs regulate more than 60% of human genes, including tumor suppressor genes and oncogenes. Accordingly, they can affect cancer risk. This study aimed to evaluate the role of serum miR-148a as a non-invasive biomarker in non-small cell lung cancer (NSCLC) patients and to assess the correlation between miR-148a and Bcl-2, as one of its target proteins.

Materials And Methods: A total of 50 newly diagnosed NSCLC cases and 30 apparently healthy controls were recruited in this study. MiR-148a level was measured by TaqMan- Real time RT-PCR assay and Bcl-2 level was measured by ELISA.

Results: Significant lower expression of serum miR-148a and higher serum Bcl-2 levels were observed in NSCLC patients as compared to the control group (p.
