The adult mouse retina samples were obtained from a pool of C57/B6 mice (n = 350), which were purchased from Charles River Laboratories (Charles River Laboratories, Inc., Willmington, MA). All samples were placed in TRIzol reagent (Invitrogen, Carlsbad, CA) and stored at -80ÂșC before RNA extraction. Total RNA was extracted with TRIzol reagent according to the manufacturer's instructions. For a quality control measure of the samples, total RNA was ran through a 1% agarose gel and using the 2100 Agilent BioAnalyzer System (Agilent Technologies, Palo Alto, CA) to check for possible contamination and degradation.
