LGALS1 and serous adenocarcinoma: Finally, we report, for the first time, an increased in vivo omental endothelial expression of Gal1 that correlates with increased microvessel density and vessel area in omentum of patients with serous carcinoma (with HGSC metastasis) compared with normal omentum or omentum of patients with non-metastatic serous carcinoma, indicating a potential proangiogenic role for Gal1 that confirms our in vitro observation.
