Article Title: INPP5E interactome reveals novel connections to growth factor signaling
doi: 10.64898/2026.02.13.705725
Figure Lengend Snippet: (a) Inpp5e +/‒ and Inpp5e ‒/‒ MEFs were stimulated with PDGF-AA or FBS for the indicated times and cell lysates analyzed by Western blot with the indicated antibodies. Actin was used as loading control. (b-c) Quantitations of normalized pAKT/AKT ratios from n=4 (S473) or n=3 (T308) independent experiments, including the one in (a). (d) Inpp5e +/+ , Inpp5e +/‒ and Inpp5e ‒/‒ MEFs cultured with or without FBS were analyzed by Western blot with the indicated antibodies. Tubulin was used as loading control and phospho-retinoblastoma (pRb) as cell cycle marker. Note INPP5E-dependence of PDGFRα receptor levels in serum-starved MEFs.
