Figure 1. UCA1 is up-regulated and predicts poor prognosis in CRC.
(a) UCA1 expression levels were analysed in 90 paired CRC and adjacent NCTs by qRT-PCR. UCA1 was obviously up-regulated in CRC tissues. (b) UCA1 was significantly up-regulated in 59% of CRC tissues compared with NCTs. (c) Kaplan-Meier overall survival curves for 90 patients with CRC classified according to relative UCA1 expression level. (d) Kaplan-Meier overall survival curves in another independent CRC cohort of 105 patients. **P < 0.01.
