FAM83A signaling induces epithelial-mesenchymal transition by the PI3K/AKT/Snail pathway in NSCLC


Figure 6. FAM83A regulated NSCLC cell EMT progression through the PI3K/AKT/Snail pathway. (AC) Protein levels of PI3K, P-PI3K p85 subunit (p-Y458), AKT, and P-AKT (p-S473) were detected by Western blot in stable H1299-LV-shRNA-NC, H1299-LV-shFAM83A-1, A549-LV-NC and A549-LV-FAM83A cells. β-actin was used as a loading control for PI3K and AKT. (DE) H460 and A549 with stable FAM83A overexpression cells were transduced with Snail siRNAs (siSnail-1/2) and a scrambled siRNA (Vector). The suppression of Snail in those cells was confirmed by Western blot. (FG) FAM83A-transfected H460 and A549 cells (with or without inhibition of MK2206 or Snail) were subjected to a wound-healing assay. Images were taken at 0 h and 24 h. (HI) Transwell assay was used to evaluate the effects of MK2206 and Snail knockdown on cell migration and invasion. Scale bar, 200 μm. Error bars: mean ± SD (n=3). *p<0.05, **p<0.01, and ***p<0.001 were considered to indicate a statistically significant difference.
