Interestingly, LKB1 loss did not affect AMPKα phosphorylation in EOC spheroids and tumor xenografts, indicating that LKB1 signaling to support EOC cell survival in spheroids and metastatic tumor growth occurs via other downstream mediators.
In this study, both the mRNA and protein expression levels of LKB1, p53, and p21 decreased in OCCs following transfection with a miR-17 expression plasmid.
Results of the present study suggested that combined therapy with eukaryotic co-expression of the plasmid‑carrying STAT3-specific siRNA and LKB1 is a novel and efficient treatment strategy for human ovarian cancer.
