In addition, animals in dierent groups showed a similar weight gain during the course of the experiment (Table S2)
After centrifugation, 10 l of the supernatant were filtered through a Microcon YM-10 centrifugal filter device (Amicon), and analyzed by reversed-phase high-performance liquid chromatography on a C18 column (Atlantis 5 m, 4,6200 mm, Waters) as previously described [18]
Gene expression analysis in ARPE-19 cells was conducted by amplifying the following genes: SOD2 (protein name: superoxide dismutase 2, mitochondrial), CAT (protein name: catalase), HMOX1 (protein name: heme oxygenase 1), SNAL1 (protein name: Snail Family Transcriptional Repressor 1), ZEB1 (protein name: Zinc finger E-box-binding homeobox 1), TWIST1 (protein name: Twist Family BHLH Transcription Factor 1), VIM (protein name: Vimentin), FN1 (protein name: Fibronectin 1), ACTA2 (protein name: actin alpha 2, smooth muscle) and GAPDH (protein name: glyceraldehyde-3-phosphate dehydrogenase)
The process is relatively painless and can take 30 minutes to an hour, depending on the treatment
