One view to reconcile these results with our observations would be that the nucleoporins implicated in repression act upstream of Ulp1 and contribute, directly or indirectly, to the maintenance of this protein at the NPC.
Neither Xist intron 1 deletion (Barakat et al. 2011), nor Tsix mutation (Lee and Lu 1999) is individually able to trigger X-inactivation in undifferentiated ES cells, suggesting that either both systems cooperate to silence Xist, and/or that other systems of repression act in ES cells.
A case study in sexual repression acted out through cruelty and censorship, Angelo is enslaved by his own passion for the chaste Isabella, who is on her way to a nunnery.
Mambush – a rock-drill operator with no official rank – emerged from the mass of black workers as a rebel leader demanding justice, while some of those who were once the spearhead of the fight against repression acted as a shield protecting privilege, exploitation and extreme violence.
We can see how that repression acts in all aspects of modern life… When we have an agency over our bodies and desire, know that we're entitled to pleasure without guilt and shame, it changes everything".
Moreover, this repression acted both through ESR2/E2 and independently of estrogens.
Since free Trp concentrations can be fairly low and still maintain highly charged tRNATrp, trpR-mediated repression acts over a large range of expression.
Besides unknown proteins, genes encoding membrane permeases represent the highest portion indicating that T. reesei carbon catabolite repression acts preferentially at the entry of substrates into the cell.
Our follow-up studies on Emi1 suggests that its translational repression acts as a mechanism to enhance post-translational protein inactivation, which could represent a more general function of translational repression in mitosis and in other processes.
First, we show that Jarid2, a Polycomb group member implicated in PRC2 recruitment, chromatin structure, and gene repression, acts as a positive regulator of PCP/Wnt signaling pathways in ESCs.
This osa-mediated repression acts on Groucho/Pangolin complex and specific downstream genes, such as Dpp, nubbin, and ubx of the Wg pathway (Collins et al. 1999; Collins and Treisman 2000; Lopez et al. 2001; Vazquez et al. 1999).
