| description | <p>Knockdown SIRT3 caused ATF4 protein decrease via translation regulation. <b>A,</b> Western blots show ATF4 protein levels in different DLBCL cells with control or SIRT3 shRNAs. SIRT3 was blotted showing knockdown efficiency, and ACTB was used as reference protein control. <b>B,</b> qPCR results reflect the mRNA levels of ATF4 and PSAT1 in OCI-LY1 cells. Samples were harvested at day 4 after viral transduction. Results were normalized to the mRNA levels in control shRNA–transduced cells. <b>C,</b> qPCR results reflect the mRNA levels of ATF4 and PSAT1 in Karpas 422 cells. Samples were harvested at day 4 after viral transduction. Actin mRNA was used as reference, and results were normalized to the mRNA levels in control shRNA–transduced cells. <b>D,</b> qPCR results show the relative levels of ATF4 mRNAs in different cell lines at different time points after shRNA transduction. Samples were harvested at days 2, 3, 4, and 7 after viral transduction. Actin mRNA was used as reference, and results were normalized to the mRNA levels in control shRNA–transduced cells. <b>E,</b> Western blots show changes of phosphorylation of EIF2A and ATF4 protein levels in Karpas 422 cells with control or SIRT3 shRNAs. Total EIF2A and ACTB were blotted as loading controls. <b>F,</b> Western blots show GFP expression from the ATF4-5′UTR-GFP reporter and endogenous ATF4 protein levels in Karpas 422 cells with control or SIRT3 shRNAs. Tubulin and ACTB were blotted as loading controls. <b>G,</b> FCs of mean fluorescence intensity (MFI) of GFP expressed from the ATF4-5′UTR-GFP translation reporter in Karpas 422 cells with control or SIRT3 shRNAs. The data were collected from days 4 and 7 after viral transduction. MFI of normal yellow fluorescent protein (YFP) expression in control or SIRT3 knockdown cells were used for normalization to avoid background translation variations. <b>H,</b> FCs of MFI of GFP expressed from the ATF4-5′UTR-GFP translation reporter in OCI-LY1 cells with control or SIRT3 shRNAs. The data were collected from days 4 and 7 after viral transduction. MFI of normal YFP expression in control or SIRT3 knockdown cells were used for normalization to avoid background translation variations. Error bars represent the mean ± SD of three or more replicates.</p> |
