SLC7A11 and ovarian cancer: Looking at the studies discussed in this review, it was revealed that SLC7A11 expression is significantly higher in ovarian cancer compared to normal tissues, but its expression in chemotherapy-resistant ovarian cancer tissues and cell lines is still a matter of debate since there are contrasting results (see Section 2), possibly due to the different techniques used to quantify SLC7A11 expression (protein or mRNA).
