Moreover, none of the herbal extracts did change the expression levels of core autophagy regulators including ULK‐1, Beclin‐1, and ATG12‐ATG5 complex in both GBM cells, though ULK‐1 and ATG12‐ATG5 complex levels were decreased by several herbal extracts in U87MG cells (Fig. S1). The gene discussed is BECN1; the disease is glioblastoma.
