VEGFA and non-small cell lung carcinoma: The results of the current study are consistent with the results from a study by Zygalaki et al (38), who investigated the expression levels of the various VEGF splice variants in NSCLC and found the total expression of VEGF, VEGF 121 and 165 in all specimens, whereas the expression of VEGF 183 and 189 was only present in small amounts in certain samples.
