SLC26A9 and triple-negative breast carcinoma: First, using the GeneCards database (https://www.genecards.org/Search), we systematically identified disease-associated targets with the keywords “SLC26A9” and “triple-negative breast cancer stem cells.” The target genes associated with SLC26A9 and those related to TNBC CSCs were then input into the online Venny 2.1 mapping platform (https://www.bioinformatics.com.cn/), revealing 457 overlapping target genes (Figure 1).
