Project description:SH-SY5Y cells were transfected with an siRNA against T-UC.300A (final concentration 50nM) or negative control siRNA (Dharmacon Negative Control #1, final concentration 50 nM) using the transfection reagent Lipofectamine (Invitrogen). Media was changed after 24hrs. RNA was extracted 120hrs after transfection. Gene expression microarray analysis was carried out using Roche NimbleGens 4x72K Homo Sapiens gene expression array.

Project description:SRPK2 was identified as a presynaptic protein kinase involved in the regulation of neurotransmitter release. The phosphoproteome of mouse primary neurons was screened, under the conditions of SRPK2 overexpression and SRPK2 knockdown, to identify candidate substrates of SRPK2.
Project description:To investigate the effect of indole on protection against colon injury and the role of IDO1 expression, we examined the effect of indole on hIDO1-overexpressing and empty vector control HCT116 cells by global gene expression profiling. Examination of mRNA levels from hIDO1-overexpressing and control HCT116 cell lines treated with 1mM indole or DMF for 24 hours using two replicates each.
Project description:Members of the phosphatidylinositol 3-kinase-related kinase family, in particular the ataxia-telangiectasia mutated (ATM) kinase and the catalytic subunit of the DNA-dependent protein kinase (DNA-PKcs), regulate cellular responses to DNA double-strand breaks. Increased sensitivity to ionizing radiation (IR) in DNA-PKcs- or ATM-deficient cells emphasizes their important roles in maintaining genome stability. Furthermore, combined knockout of both kinases is synthetically lethal, suggesting functional complementarity. In the current study, using human mammary epithelial cells with ATM levels stably knocked down by >90%, we observed an IR-induced G(2) checkpoint that was only slightly attenuated. In marked contrast, this G(2) checkpoint was significantly attenuated with either DNA-PK inhibitor treatment or RNA interference knockdown of DNA-PKcs, the catalytic subunit of DNA-PK, indicating that DNA-PK contributes to the G(2) checkpoint in these cells. Furthermore, in agreement with the checkpoint attenuation, DNA-PK inhibition in ATM-knockdown cells resulted in reduced signaling of the checkpoint kinase CHK1 as evidenced by reduced CHK1 phosphorylation. Taken together, these results show a DNA-PK-dependent component to the IR-induced G(2) checkpoint, in addition to the well-defined ATM-dependent component. This may have important implications for chemotherapeutic strategies for breast cancers.
