Immunostaining and scoring guide of CYP4Z1 expression in ovarian cancer. The expression was observed as either membranous or cytoplasmic staining. (A) Score “0” reveals totally negative expression, (B) score “1” shows expression of less than 1% of cells, (C) score “2” shows expression levels between 1 and 10% of cells, (D) score “3” shows expression between 11 and 33% of cells, (E) score “4” illustrates expression between 34 and 66% of cells, and (F) score “5” shows expression levels of more than 67% of cells.
