Western blot analysis of extracts from HeLa cells, untransfected or transfected with either GSK-3alpha/beta siRNA #6301 or GSK-3alpha siRNA. GSK-3alpha and GSK-3beta were detected using a GSK-3alpha/beta antibody, and eIF4B was detected using eIF4B Antibody #3592. The GSK-3alpha/beta antibody confirms silencing of GSK-3alpha and beta expression, and the eIF4B Antibody is used to control for loading and siRNA specificity.Learn more about how we get our images
Fluorescent detection of SignalSilence® Control siRNA (Fluorescein Conjugate) #6201 in living HeLa cells 24 hours post-transfection, demonstrating nearly 100% transfection efficiency.Learn more about how we get our images
CST recommends transfection with 100 nM GSK-3α siRNA 48-72 hours prior to cell lysis.
SignalSilence® siRNA is supplied in RNAse-free water. Aliquot and store at -20ºC.
SignalSilence® GSK-3α siRNA I from Cell Signaling Technology allows the researcher to specifically inhibit GSK-3α expression using RNA interference, a method in which gene expression can be selectively silenced through the delivery of double stranded RNA molecules into the cell. All SignalSilence® siRNA products are rigorously tested in-house and have been shown to reduce protein expression in specified cell lines.
Glycogen synthase kinase-3 (GSK-3) was initially identified as an enzyme that regulates glycogen synthesis in response to insulin (1). GSK-3 is a ubiquitously expressed serine/threonine protein kinase that phosphorylates and inactivates glycogen synthase. GSK-3 is a critical downstream element of the PI3K/Akt cell survival pathway whose activity can be inhibited by Akt-mediated phosphorylation at Ser21 of GSK-3α and Ser9 of GSK-3β (2,3). GSK-3 has been implicated in the regulation of cell fate in Dictyostelium and is a component of the Wnt signaling pathway required for Drosophila, Xenopus, and mammalian development (4). GSK-3 has been shown to regulate cyclin D1 proteolysis and subcellular localization (5).
Small Interfering RNA (siRNA) has been used to specifically silence GSK-3α expression, causing an upregulation of β-catenin protein levels (6).
