A fluorescence-based and real-time detection method was used to determine the relative cDNA quantification for ERCC1 BRCA1 RRM1 and RRM2 and AY-actin was used as the reference gene.
The standardized mRNA quantification amount of ERCC1 BRCA1 RRM1 and RRM2 was as- sessed by comparing the target amount of AY-action amount.
However we did not find the low level of RRM1 (OR=1.43 95%CI=0.79-2.57) and RRM2 (OR=1.13 95%CI=0.63-1.13) mRNA expres- sion has a role on the response to platinum-based chemotherapy.
How- ever no association was found between RMM1 and RRM2 mRNA expression and prognosis of NSCLC.

Recently several studies reported the association between ERCC1 BRCA1 RRM1 and RRM2 mRNA expression and clinical outcome of NSCLC.38-13 Zhang et al.

The relatively sample size may be the reason that no association was found between RRM1 and RRM2 mRNA expression and clinical outcome of NSCLC patients.
The researchers created the particles from two polymers plus a protein that binds to receptors on the surface of cancer cells and pieces of RNA called small-interfering RNA, or siRNA, designed to stop the
RRM2 gene from being translated into protein.
