MX1 and lung cancer: Indeed, cytoplasmic MxA condensates in liver and lung cancer cells turned out to be sensitive sensors of hypotonicity—the condensates disassembled within 1–2 min of exposure of cells to hypotonicity (range 40–100 mOsm), and reassembled in 1–2 min but into new condensate structures when cells were returned to isotonic medium (300–330 mOsm) [19,20,24].
