Although the number of studies involving SOX9-AS1 is limited and has more frequently been described as a predictive factor for poor prognosis, as shown for HCC, and ICC cells, we suggest that high expression of SOX9-AS1 might serve as a biomarker of good prognosis in TNCB tissue specific biological mechanisms in the cytoplasm of TNBC cells. This evidence concerns the gene SOX9 and hepatocellular carcinoma.
