RT-qPCR validation of the expression levels of randomly selected DE circRNAs (listed in Table I) in exosomes from patients with GC and HC. GAPDH was used as internal standard. Expression level of each circRNA in sample HC190128-1 was set as 1. Data were expressed as the means ± standard deviation of the mean (n=5). **P<0.01 and ***P<0.001 vs. respective HC. RT-qPCR, reverse transcription quantitative PCR; DE circRNAs, differently expressed circular RNAs; GC, gastric cancer; HC, healthy control.
