Objective:
2
To study the protective effect of anthocyanins extracted from
Vaccinium Uliginosum
(VU) on retinal 661W cells against microwave radiation induced retinal injury.
Methods:
2
661W cells were divided into 6 groups
including control
model [661W cells radiated by microwave (30 mW/cm
2
1 h)] and VU groups [661W cells pretreated with anthocyanins extracted from VU (25
50
100 and 200 μg/mL
respectively) for 48 h
and radiated by microwave 30 mW/cm
2
1 h]. After treatment with different interventions
the cell apoptosis index (AI) was determined using Heochst staining; contents of malonaldehyde (MDA)
glutataione (GSH)
and activity of superoxide dismutase (SOD) were measured. mRNA expressions of nuclear factor erythroid 2-related factor 2 (Nrf2) and heme oxygenase 1(HO-1) were detected by real time quantitative polymerase chain reaction
and the expression of HO-1 protein was examined by Western blot analysis. Nucleus and cytoplasm were separated and Nrf2 protein expression was further verified by Western blot analysis.
Results:
2
There was significant difference in AI among the groups (
F
=322.83
P
<
0.05). Compared with the control group
AI was significantly higher in the model group and was lower in 4 VU-pretreated groups (
P
<
0.05). Linear regression analysis showed the decline of AI was in a dose-dependent manner with VU treatment (
r
=0.8419
P
<
0.05). The MDA and GSH contents of 661W cells in VU-treated groups were significantly lower than the model group (
P
<
0.05). Compared with the model group
the SOD activity in the VU-treated groups (50
100 and 200 μg/mL) was significantly higher (all
P
<
0.05). The Nrf2 and HO-1 mRNA expressions were slightly increased after irradiation
and obviously increased in 100 μg/mL VU-treated group. After irradiation
the relative expressions of HO-1 and Nrf2 proteins in nucleus were slightly increased (
P
<
0.05)
and the changes in cytoplasm were not obvious
whereas it was significantly increased in both nucleus and cytoplasm in the VU treatment groups.
Conclusions:
2
Anthocyanins extracted from VU could reduce apoptosis
stabilize cell membrane
and alleviate oxidant injury of mouse retinal photoreceptor 661W cells. The mechanism might be through activating Nrf2/HO-1 signal pathway and inducing HO-1 transcription and translation.
