LincRNA for kinase activation (LINK‐A) is an oncogene in breast cancer, in which it activates HIF1α to promote triple‐negative breast cancer progression.95 Researchers found that plasma circulating LINK‐A is high expressed in metastatic OS patients compared to non‐metastatic OS ones, suggesting that LINK‐A might be associated with the OS metastasis specifically. The gene discussed is LINC01139; the disease is breast cancer.
