The ADAMTS9 gene is widely expressed in foetal and adult tissues, functioning as a tumour suppressor gene in diverse cancer types.75 Overexpression of ADAMTS9‐S2 in glioma cells inhibited cell migration and invasion, while ADAMTS9‐S2 silencing increased the malignancy of GBM cells, validating its tumour suppressor activity.76 Here, ADAMTS9 is linked to glioblastoma.
