A recent paper suggests that STK24 regulates STAT3/VEGFA signaling pathway and promotes cell cycle in human non‐small cell lung cancer cell lines.[12] However, in our experimentation with A549 cells, neither the suppression nor overexpression of STK24 yielded detectable effect on cell cycle dynamics, proliferation, or STAT3 expression (Data not shown). This evidence concerns the gene STAT3 and lung cancer.
