PTEN and non-small cell lung carcinoma: Actually, our present and previous studies showed that Snail or Slug overexpression in A549 cells decreased maspin or PTEN expression [58], but the functional roles of maspin, PTEN, and LSD1 in Snail/Slug-regulated Akt activity and the effects of API on these regulators in NSCLC cells with different EGFR statuses should be further evaluated in the future.
