BECN1 and ovarian cancer: To further verify this, we examined the expression of phosphorylated BECN1 in stably overexpressed and stably knockdown LOC730101 cells before and after drug treatment by Western Blot and found that high expression of LOC730101 could inhibit the expression of p-BECN1Thr119 expression, whereas p-BECN1Thr119 expression was increased in knockdown LOC730101 ovarian cancer cells (Fig. 4I).
