TRA disrupts the PI3K/AKT interaction, and this disruption is not easily reversed shortly after withdrawal. However, ETPs exert positive effects on PI3K/AKT signaling by promoting the expression of VEGF, VEGFR1, and R2. These results highlight the potential of ETPs to ameliorate the adverse effects of TRA on VEGF/VEGF R1, R2/PI3K/AKT signaling, even a short time after withdrawal.
Saeidifard et al. (Mon,) studied this question.
