TNFSF10 and non-small cell lung carcinoma: By using differential whole-cell SELEX on human NSCLC we identified a set of five families of sequence related 2′-fluoro pyrimidines (2′-F Py) RNA-aptamers that distinguish A549 cells (resistant to cell death induced by TRAIL, cisplatin and paclytaxel) from the more sensitive H460 cells.
