On the other hand, we found that TACSTD2 expression was downregulated 1.23-fold (p = 0.14) and 1.47-fold (p = 0.87) in the PCa group, compared to that in their normal prostate gland counterparts from the Grasso Prostate and Tomlins Prostate cohorts, respectively (Figure 1C,D). This evidence concerns the gene TACSTD2 and posterior cortical atrophy.
