Fig. 2From: Profiling and bioinformatics analyses reveal differential circular RNA expression in radioresistant esophageal cancer cellsCircRNA expression changes validated by qRT-PCR. Validation of microarray analysis data by qRT-PCR. The expression levels of 9 circRNAs were determined by qRT-PCR. Each qRT-PCR assay was performed at least three times. *P < 0.05Back to article page
