Expression of VEGF165 mRNA in synovial tissues: preliminary study. Expression levels of VEGF165 mRNA were measured by real-time PCR. The mRNA levels were normalized to the expression of β-actin. The box plots demonstrate the 10th and 90th percentile (whiskers), the 25th and 75th percentile, and the median. VEGF165 mRNA levels were not significantly altered in RA (n = 25) synovial tissues compared with OA (n = 17) (A). VEGF165 expression levels did not significantly correlate with DAS28-CRP. (B)
