In patient tissue, it was interesting to note that although Snail and Cat L expression was high in prostate cancer tissue from AA, Bahamian, and CA origin, when all the different stages were grouped together, normal tissue from AA also expressed high levels of Snail and Cat L while it was intermediate in Bahamian prostate cancer tissue when compared to normal CA prostate tissue. Here, SNAI1 is linked to prostate carcinoma.
