To further investigate the role of APC in repression, we tested the ability of Groucho to repress TOPFlash activity in colon cancer cell lines with wild type or variant APC proteins, predicting that Groucho would not be able to oppose β-catenin actions in cell lines with truncated APC proteins.
To determine whether BRK binding is an essential component of WG mediated dpp repression, we tested the ability of WG signaling to repress reporter constructs when the BRK sites are mutated.
TNRC6 proteins, key players in miRNA repression, were tested for their interactions with eIF4E1 and eIF4E2 by coimmunoprecipitation assays.
To further examine whether or not direct binding of DAZL to the cis-element is sufficient for the relief of miRNA-mediated repression, we tested a reporter mRNA, GFP-3xIPTmiR-430 6x#16, conthreeng three copies of the miR-430 target site fused with six copies of the in vitro selected DAZL-binding sequence, #16, that possessed the GUUC element [15] (Fig. 3A).
As MeCP2 is known to recruit HDACs to target genes for transcriptional repression, we tested whether MeCP2 modulates splicing of ASEs via recruiting the activities of HDACs.
To assess if 15d-PGJ2 modupstreampsignallingnaleadingeading to Stat3 repression, we tested the effect of 15d-PGJ2 on IL-6-mediated Stat3 phosphorylation.
The country's first multi-party election is due this year.With the president's future uncertain, his government has descended into tried and tested repression.
For all the MS genes tested, repression by MetJ was generally very tight (RR ≤ 0.12 for ybdH, mtnA, mtnB, mtnK, mtnE and mtrB in E. coli, Yersinia or Klebsiella, but 0.42 for mtrA in Klebsiella).
The 3′LIFE screen is a high throughput dual luciferase assay, previously shown to detect functional repression of test 3′UTRs by query miRNAs [ 8, 18].
We therefore first evaluated this possibly by testing the effect of TNFR1 repression on ER stress-induced death.
