An association study revealed a positive correlation between Gal1 and number of vessels (Spearman coefficient, r = 0.8702, p < 0.001), and area of vessels (r = 0.7283, p < 0.001) (Fig. 5e), suggesting a potential proangiogenic role for Gal1 in the omentum of advanced ovarian carcinoma. This evidence concerns the gene LGALS1 and ovarian carcinoma.
