Analysis of the prostate cancer progression study conducted by Tomlins et al. [13] revealed that in benign samples both EPHB4 and ITGB8 are expressed at a low level and this increases dramatically and significantly in prostatic intraepithelial neoplasia (PIN) (ITGB8: 9.5 fold, p = 1.24 x 10-4 and EPHB4 2.9 fold, p = 0.001), the precursor for prostate carcinoma [14]. Here, ITGB8 is linked to prostate carcinoma.
