VIM and ocular melanoma: In OM fat, only the expression of carbonylated protein serpin A (p = 0.013), a serine inhibit protease involved in the control of ER stress response among other functions, and carbonylated transferrin (p = 0.036), an iron protein transport and carbonylated vimentin (p = 0.028) were significantly higher in Ob-IR vs. Ob-NG (Figure 3A–C).
