Context:MicroRNAs (miRNAs) are a class of short, endogenously-initiated, non-coding RNAs that post-transcriptionally control gene expression via translational repression or mRNA turnover. MiRNAs have attracted much attention in recent years as they play critical roles in gene expression and are promising tools with many biotech and therapeutic applications. The molecular mechanisms und...

Severe transient repression of constitutive or induced beta-galactosidase synthesis occurs upon the addition of glucose to cells of Escherichia coli growing on glycerol, succinic acid, or lactic acid. Only mutants particularily well adapted to growth on glucose exhibit this phenomenon when transferred to a glucose-containing medium. No change in ribonucleic acid (RNA) metabolism was observed du...

Alongside the well-established carbon catabolite repression by glucose and other sugars, acetate causes repression in Aspergillus nidulans. Mutations in creA, encoding the transcriptional repressor involved in glucose repression, also affect acetate repression, but mutations in creB or creC, encoding components of a deubiquitination system, do not. To understand the effects of acetate, we used ...

Findings on the effect of repression political participation are mixed and inconclusive. This article addresses this puzzle by introducing conceptualizing ‘responses to repression’ as individuals’ varying willingness risk-taking continuing with activities despite possible threats. We use three-wave panel survey data focus run-up 2013 Iranian presidential elections, during which gradual decline ...

The repression-protest nexus in authoritarian regimes has attracted scholarly attention of contention scholars for a long time. However, studies have generally overlooked pro-government actors’ role contentious dynamics. This article introduces an original event dataset on protests, repression, and rallies Turkey under the rule Justice Development Party during period which authoritarianism incr...
