SLC31A1 and ovarian serous cystadenocarcinoma: In addition, we investigated the relationship between SLC31A1 expression and pathological tumour stage using Gene Expression Profiling Interactive Analysis 2.0(GEPIA2.0)7 and found that SLC31A1 expression is associated with KIRC, adrenocortical carcinoma (ACC), ovarian serous cystadenocarcinoma (OV), and THCA (Fig. 1D).
