Abstract:
AIM:To determine the location of c-jun protein, dynamic changes in c-jun mRNA and protein expression, and ultrastructure characteristics in the rd mouse retina, following a single dose of brain-derived neurotrophic factor (BDNF) in a short period of time. METHODS:A single intravitreal injection of BDNF at two dosages (25µg/L or 50µg/L) was given to the right eye of the rd mouse at age 2 and 3 weeks respectively. Two weeks after injection, the location of c-jun protein in the retina was observed by immunofluorescence detection, c-jun mRNA and protein expression in retinas were detected by quantitative real time polymerase chain reaction (RT-PCR) and western immunoblotting analysis, ultrastructure characteristics of retinas were detected by transmission electron microscope (TEM) observation. RESULTS:c-jun protein was expressed in the inner nuclear layer (INL) of retina. BDNF at two dosages (25µg/L and 50µg/L) increased c-jun mRNA expression at PN-4 weeks respectively (P(1)=0.019, P(2)=0.021). 50µg/L BDNF increased c-jun protein expression at PN-4 weeks (P =0.000). The retinal ultrastructure was improved. CONCLUSION:The effects of BDNF exerts on the c-jun expression in the retina are dose-dependent and time-dependent, which may mediate photoreceptor rescue indirectly in the pathological process of retinitis pigmentosa (RP) at early stage.
