存活率

After the cell growth curves was recorded, RPE cells of the 3-5th passages were utilized. 2、Three different siRNA (siRNAl,siRNA2,siRNA3) targeting against human cx43 gene and one negative control siRNA were designed and transfected into cultured human RPE cells via liposome reagent. The most effective siRNA can be determined by semi-quantitative reverse transcription PCRRT-PCR. 3、To the most effective siRNA, after transfected into human RPEs with different concentration, the cellular proliferate activities were messured by MTT colorimetry ; the percentages of RPE in different cell circle phase was assayed by FCM; the changes of phenotypical properities were observed with SCM; the protein expression of cx43 was studied through immunocytochemistry stain and Weston blot; the communication intercellular was calculated with FRAP; and the ability of recovery was assessed by using an in vitro wound healing model.4、The total proteins of siRNA1 and RPE were seperated by two-dimensional gel electrophoresis and visualized by silver staining. Proteins with significant expression alterations were selected and their peptide mass fingerprints (PMFs were obtained by matrix-assisted laser desorption/ionization time of flying mass spectrometry (MALDI-TOF-MS).The PMFs were used to search NCBInr database by Auto MS-Fit software.
