Expression of the UCA1 gene in urinary samples determined by semi-quantitative RT-PCR. This figure illustrates the expression of the UCA1 gene in urinary samples determined by semi-quantitative RT-PCR. Lanes 1 and 2 were negative controls for PCR (1) and reverse transcription (2). Lane 11 was the positive control consisting of RNA extracted from frozen bladder cancer tissue. TBP was used as an internal control. Cases (4) and (10) were considered unsatisfactory for evaluation because no TBP expression was detected. Cases (3) and (6) had no UCA1 expression, cases (5) and (8) had weak UCA1 expression and cases (7) and (9) had strong UCA1 expression.
