αB-晶狀體蛋白對急性高眼壓大鼠視網膜神經節(jié)細胞保護作用機制的研究
[Abstract]:Objective to study the effects of 偽 B-crystallin on potassium channel kv1.1,kv1.3, apoptosis inhibitor Bcl-xl and apoptosis factor Caspase-3, and to explore the effect of 偽 B-crystallin on (retinal ganglion cells, in retinal ganglion cells of rats with acute ocular hypertension. RGC) the mechanism of protective effect. Methods Sixty SD rats were randomly divided into group A (), B group with acute hyperocular pressure, group 5 渭 L with intravitreal injection of normal saline). Group C (10 脳 10 g 路L-1 偽 B-crystallin 5 渭 L) received intravitreal injection of 10 脳 10 脳 10 g 路L-1 偽 B-crystallin in group C with 20 eyes in each group, and the right eye was the experimental eye. Western blot and real-time quantitative reverse transcription polymerase chain reaction (QRT-PCR) were used to detect the expression of kv1.1,kv1.3,Bcl-xl and Caspase-3 in retina 7 d and 14 d after injection. Results on the 7th and 14th day after injection, the expression level of kv1.1,kv1.3 channel protein and apoptosis factor Caspase-3 protein and the relative expression of mRNA in group C were lower than those in group A and group B (P 0.05). The expression level of Bcl-xl protein and the relative expression of mRNA in group C were significantly higher than those in group A and group B (P 0.05). At the same time point, there was no significant difference between group A and group B in different factors (P 0.05). Conclusion 偽 B-crystallin can increase the expression of inhibitor of apoptosis factor Bcl-xl and decrease the expression of apoptosis factor Caspase-3 and decrease apoptosis by inhibiting the expression of potassium channel kv1.1,kv1.3 in RGC after acute ocular hypertension. Protect RGC.
