Figure 1From: Activation of synovial fibroblasts in rheumatoid arthritis: lack of expression of the tumour suppressor PTEN at sites of invasive growth and destructionAnalysis of the amplified polymerase chain reaction products byelectrophoresis on a 1% agarose gel. The expected PTEN band was visible in allnormal (N1, N2 in lanes 3 and 4) and rheumatoid arthritis (R1-R7 in lanes 6–12)specimens, and no additional transcripts could be detected, even at lowerspecificity.Back to article page
