LGALS3 and posterior cortical atrophy: Given the promising diagnostic role of Gal-3 in the urine of PCa patients found in our previous studies [39], its concordant gene and protein expression levels, and its involvement in PCa-related biological processes (e.g., prostate-gland epithelium morphogenesis, cell migration and invasion) [39], we aimed to study this protein immunohistochemically in prostate tissue.
