Bioinformatics analysis identified that ADAMTS9-AS1 participated in the initiation and progression of epithelial ovarian cancer [16], and demonstrated a role of a novel prognostic biomarker in esophageal squamous cell carcinoma [17], papillary renal cell carcinoma [18], breast cancer [19], and bladder cancer [20,21]. Here, ADAMTS9 is linked to breast carcinoma.
