WebSep 30, 2024 · Induction of ATF4 has been reported in cellular and animal models of PD as well as in post-mortem brain tissue of PD patients (Mercado et al., 2024a; Ryu et al., 2002; Sun et al., 2013). However, the role of ATF4 in regulating neuronal survival remains controversial. Therefore, in the present study we investigated the role of ATF4 in primary ... WebAs all members of the C/EBP family have the potential to heterodimerize with ATF4 and contribute to the induction of these gene targets (Newman and Keating, 2003), we first determined the effects of siRNA-mediated knockdown of individual isoforms, relative to ATF4 knockdown, on expression of three representative genes in Tsc2-/-MEFs, which …
