The expression level of VEGF-A, VEGFR-1, and VEGFR-2 genes
| Gene | Expression level | Number of cases (%) |
|---|---|---|
| VEGF-A | Low expression | 37 (61.7%) |
| High expression | 23 (38.3%) | |
| VEGFR-1 | Low expression | 41 (68.3%) |
| High expression | 19 (31.7%) | |
| VEGFR-2 | Low expression | 41 (68.3%) |
| High expression | 19 (31.7%) |
Patients with a value of 2-ΔCt inferior to the median are considered as low expressed for the corresponding gene and vice versa
