forward, CCCTGATGAGATCGAGTACATCTT (this primer
was used for detecting both 121 and 165 species);
VEGF-165 reverse, AGCAAGGCCCACAGGGATTT;
VEGF-121 reverse GCCTCGGCTTGTCACATTTT.
The PCR reactions contained a final concentration
of 1 SYBR Green PCR Master Mix (Applied
Biosystems, Warrington, UK), 10 mM specific primers,
and 2.5 ng of cDNA. Each gene expression
were calculated according to the threshold cycle
(CT) value, normalized using the value of the sample
