| 描述 | SignalSilence® mTOR siRNA I (Mouse Specific) from Cell Signaling Technology (CST) allows the researcher to specifically inhibit mTOR expression using RNA interference, a method whereby gene expression can be selectively silenced through the delivery of double stranded RNA molecules into the cell. All SignalSilence® siRNA products from CST are rigorously tested in-house and have been shown to reduce target protein expression by western analysis. |

| 背景 | The mammalian target of rapamycin (mTOR, FRAP, RAFT) is a Ser/Thr protein kinase (1-3) that functions as an ATP and amino acid sensor to balance nutrient availability and cell growth (4,5). When sufficient nutrients are available, mTOR responds to a phosphatidic acid-mediated signal to transmit a positive signal to p70 S6 kinase and participate in the inactivation of the eIF4E inhibitor, 4E-BP1 (6). These events result in the translation of specific mRNA subpopulations. mTOR is phosphorylated at Ser2448 via the PI3 kinase/Akt signaling pathway and autophosphorylated at Ser2481 (7,8). mTOR plays a key role in cell growth and homeostasis and may be abnormally regulated in tumors. For these reasons, mTOR is currently under investigation as a potential target for anti-cancer therapy (9). |

Western blot analysis of extracts from NIH/3T3 cells, transfected with 100 nM SignalSilence® Control siRNA (Unconjugated) #6568 (-), SignalSilence® mTOR siRNA I (Mouse Specific) (+), or SignalSilence® mTOR siRNA II (Mouse Specific) #6342 (+) using mTOR (7C10) Rabbit mAb #2983 (upper) or α-Tubulin (11H10) Rabbit mAb #2125 (lower). The mTOR (7C10) Rabbit mAb confirms silencing of mTOR expression, while the α-Tubulin (11H10) Rabbit mAb is used as a loading control.
