Long noncoding RNA FTX was overexpressed in human renal cell carcinoma (RCC) tissues and cells. (A) Total RNAs were extracted from 150 clinical RCC tissues and their adjacent noncancerous tissues and subjected to real-time polymerase chain reaction (RT-PCR) analysis. The transcript level of FTX in the tumor tissues was fourfold higher than that in their noncancerous counterparts. *p < 0.05 versus Adjacent. (B) Five RCC cell lines and a control renal cell line HKC were included to assess the expression of FTX in RCC cells by RT-PCR assays. A498 and ACHIN showed the highest transcript levels of FTX, while other RCC cells also presented higher FTX expressions compared with HKC cells. *p < 0.05 versus HKC cells.
