In addition, the enhancement of the stemness of glioma cells mediated by TGF‐β was abrogated by UCA1 knockdown, evident by the rescue of sphere formation (Fig. 2E,F), ALDH1 activity (Fig. 2G) and the expression of stemness markers (Fig. 2H–J). The gene discussed is ALDH1A1; the disease is central nervous system cancer.
