Question: Is mRNA expression of RRM1 , ERCC1 and ERCC2 associated with chemosensitivity to cisplatin , carboplatin and gemcitabine in human lung cancer cell lines?
Answer: These in vitro results suggest that further studies are needed to evaluate the expression of the RRM1, ERCC1 and ERCC2 genes as predictive biomarkers for sensitivity to platinum agents and gemcitabine.
no
