The results confirm that this human Müller cell line responds to ADR stimulation with phosphorylation of ERK and AKT, which suggests that it is possible to pharmacologically target ADR to modulate the early events in human Müller cell dedifferentiation in a similar fashion as been shown for chicken Müller cells.
Compared with the control group, the proliferation and migration of BIU87cells and the expression of p-AKT were significantly decreased in the study group; the inhibitory effect of the downregulation of p-AKT by LY-294002on the induction of BIU87cells proliferation and migration was identical to that of Lycium barbarum polysaccharides; upregulation of p-AKT by IGF-1 reversed the Lycium barbarum polysaccharides-induced inhibition of BIU87cells dedifferentiation.
The deletion of SCH9 (homologous to AKT and S6K), but not CR, protects against the age-dependent defects in sgs1Delta by inhibiting error-prone recombination and preventing DNA damage and dedifferentiation.
