There was no evident distinction among CD31 and CD34 expression in anterior glandular lesion tissue (pCD31vsCD34 = 0.243 > 0.05), while there was a significant difference when comparing between CD31 and CD105, and between CD34 and CD105 (pCD31vsCD105 = 0.000 < 0.05, pCD34vsCD105 = 0.000 < 0.05); otherwise, in lung cancer tissues, there were significant differences when comparing between CD31 and CD34, between CD31 and CD105, and between CD34 and CD105 (pCD31vsCD34 = 0.019 < 0.05, pCD31vsCD105 = 0.000 < 0.05, pCD34vsCD105 = 0.000 < 0.05) (Table 1). This evidence concerns the gene ENG and lung carcinoma.
