BACKGROUND AND OBJECTIVE: Lung cancer is a disorder that is caused by genetic and epigenetic changes and activates oncogenes and inactivates tumor suppressor genes. The aim of this study is to quantitative evaluation of EGFR and FGFR4 genes expression level in blood samples of lung cancer in compare with normal people to investigate the role of these two genes as biomarkers during lung cancer diagnosis and screening.
METHODS: This case-control study was performed on 50 blood samples of lung cancer patients compared with 50 normal controls.. Total RNA from Blood samples were extracted and cDNA is synthesized. The specific primers for detection of markers are designed and expression level of BRIP1, PALB2 in presence of gene GAPDH by using Real Time PCR method was quantitatively studied.
FINDINGS: Significant increase was observed in the expression of target biomarkers in cancer patients compared to control population. Results showed quantitative increase of FGFR4 and EGFR genes with 4.46 and 3.03 fold respectively for lung cancer in compare with normal samples (p=0.003). Also, there was a significant relationship between grade of the disease and biomarkers expression level, so that with increasing the stage and degree of severity of cancer, the expression of biomarkers increased (p=0.003).
CONSLUSION: Based on this study results we could predict the expression level of (EGFR, FGFR4) gens in suffered patients quantitatively which could use as biomarker indicator during screening of lung cancer samples. |
