The mean of serum galectin-3 concentration in patients with psoriasis was 6.23 ± 0.487 ng/mL before treatment and after 5.74 ± 0.461 ng/mL, and was significantly higher compared to the control group: 3.44 ng/mL ± 0.537 ng/mL (p < 0.01) (Figure 1). This evidence concerns the gene LGALS3 and psoriasis.
