PTK2 and neoplasm: In addition to inhibiting cancer metastasis by decreasing the secretion of VEGF-A [62], TQ (20 μM) also inhibits the eukaryotic elongation Factor 2 kinase eEF-2K, which has a central role in TNBC tumor proliferation and progression by regulating the activity of pathways, such as Src, FAK, PI3K/Akt, c-Myc, and cyclin D1 [63].
