Comment[ArrayExpressAccession] E-GEOD-56943 MAGE-TAB Version 1.1 Public Release Date 2014-04-22 Investigation Title Genes regulated by Gadd45a during somatic cell reprogramming Comment[Submitted Name] Genes regulated by Gadd45a during somatic cell reprogramming Experiment Description Gadd45a can enhance somatic cell reprogramming significantly. To explore the roles of Gadd45a playing in reprogramming, we performed whole genome microarray to identify genes and signals pathways that regulated by Gadd45a. Genes expression of MEFs was measured at day8 in reprogramming. Three samples were set: MEFs infected with SKO plus Flag, MEFs infected with SKO plus Gadd45a and MEFs infected with SKO plus G39A which is a negative mutant of Gadd45a.

Raw data were normalized by Quantile algorithm, Gene Spring Software 11.0 (Agilent technologies, Santa Clara, CA, US). ID_REF = VALUE = Normalized signal intensity Total RNA was amplified and labeled by Low Input Quick Amp Labeling Kit, One-Color (Cat#5190-2305, Agilent technologies, Santa Clara, CA, US), following the manufacturer’s instructions. Labeled cRNA were purified by RNeasy mini kit (Cat#74106, QIAGEN, GmBH, Germany). Each Slide was hybridized with 1.65μg Cy3-labeled cRNA using Gene Expression Hybridization Kit (Cat#5188-5242, Agilent technologies, Santa Clara, CA, US) in Hybridization Oven (Cat#G2545A, Agilent technologies, Santa Clara, CA, US), according to the manufacturer’s instructions. After 17 hours hybridization, slides were washed in staining dishes (Cat#121, Thermo Shandon, Waltham, MA, US) with Gene Expression Wash Buffer Kit(Cat#5188-5327, Agilent technologies, Santa Clara, CA, US), followed the manufacturer’s instructions。 MEFs were infected with certain virus and then cultured in DMEM/High Glucose plus +15%FBS+NEAA+Gluta Max+Sodium Pyruvate+lif for 6 days. Total RNA was extracted using TRIZOL Reagent (Cat#15596-018,Life technologies, Carlsbad, CA, US)following the manufacturer’s instructions and checked for a RIN number to inspect RNA integration by an Agilent Bioanalyzer 2100 (Agilent technologies, Santa Clara, CA, US).Qualified total RNA was further purified by RNeasy mini kit (Cat#74106, QIAGEN, GmBH, Germany) and RNase-Free DNase Set (Cat#79254, QIAGEN, GmBH, Germany). Slides were scanned by Agilent Microarray Scanner (Cat#G2565CA, Agilent technologies, Santa Clara, CA, US) with default settings, Dye channel: Green, Scan resolution=3μm, 20bit.
