Does long non coding RNA-UCA1 contribute to cardiomyocyte apoptosis by suppression of p27 expression?
Reduction of UCA1 levels plays a pro-apoptotic role in primary cardiomyocytes partially through stimulation of p27 protein expression. These results are in agreement with the observed levels of UCA1, p27 and apoptosis after cardiac I/R injury, suggesting that UCA1 might have an important role during I/R injury.
The spatial distribution of macular pigment is related to the size of the FAZ, in addition to the central foveal thickness. It is possible that xanthophyll pigment accumulation in the macula serves functions, such as attenuation of shorter wavelengths of light, that would have been provided by the light-filtering characteristics of blood vessels.
