ANXA2 Depleted Cells Show Enhanced AKT Activation Upon Oncogenic Ras Transformation 2.2. ANXA2 Depleted Cells Show Enhanced AKT Activation Upon Oncogenic Ras Transformation We next questioned if ANXA2 could play a role within the regulation of other oncogenic H22O2 We subsequent questioned if ANXA2 could play a part in the regulation of other oncogenic H O2 inducing signaling pathways. We transformed HT1080 and MDAMB231 ANXA2 depleted and inducing signaling pathways. We transformed HT1080 and MDAMB231 ANXA2 depleted and handle cells with oncogenic HRasV12 or or empty vector (pBABE). Cells depleted of ANXA2 and handle cells with oncogenic HRasV12 empty vector (pBABE). Cells depleted of ANXA2 and overoverexpressing oncogenic HRasV12 showed enhanced pSer473 AKT (Figure 1C,D) when compared with expressing oncogenic HRasV12 showed enhanced pSer473 AKT (Figure 1C,D) in comparison to ANXA2 ANXA2 scramble cells overexpressing HRasV12 or pBABE expressing cells. The activationof the scramble cells overexpressing HRasV12 or pBABE expressing cells. The activation from the MAPKERK12 signaling pathwaywas considerably higher in HRasV12 expressing cells compared MAPKERK12 signaling pathway was substantially larger in HRasV12 expressing cells when compared with controls (pBABE), even so no differences were observed amongst ANXA2 depleted and matched to controls (pBABE), nevertheless no differences had been observed among ANXA2 depleted and matched control cells (Figure 1C,D). manage cells (Figure 1C,D). two.three. ANXA2 By way of Cys8 Residue Interacts with PTEN and Regulates Its Activity two.three. ANXA2 By way of Cys8 Residue Interacts with PTEN and Regulates Its Activity We observed enhanced activation of AKT in ANXA2 depleted in comparison with manage cells in We observed enhanced activation of AKT in ANXA2 depleted when compared with control cells in response to H2 O2 dependent signaling. Primarily based on these data we questioned if ANXA2 could response to H2O2dependent signaling. Based on th.
