RNA silencing suppressors from different plant viruses are structurally diverse. In addition to inhibiting the antiviral silencing response to condition susceptibility, many suppressors are pathogenicity factors that cause disease or developmental abnormalities. Here, unrelated suppressors from multiple viruses were shown to inhibit microRNA (miRNA) activities and trigger an overlapping series ...
In plants, small interfering RNAs (siRNAs) and microRNAs (miRNAs) are effectors of RNA silencing, a process involved in defense through RNA interference (RNAi) and in development. Plant viruses are natural targets of RNA silencing, and as a counterdefensive strategy, they have evolved highly diverse silencing suppressor proteins. Although viral suppressors are usually thought to act at distinct...
Elite suppressors are untreated individuals with human immunodeficiency virus type 1 (HIV-1) infection who maintain viral loads <50 copies/mL. Using a single-copy assay, we show that there is no statistically significant difference between the proportions of elite suppressors and patients receiving suppressive highly active antiretroviral therapy who have viral loads of <1 copy/mL.
Cancer research has been significantly accelerated by viewing cancer as a functional collision between 2 dichotomous sets of genes: oncogenes and tumor suppressors. Signaling pathways turn oncogenes and tumor suppressors on and off to dictate cell fate decisions. We contend that signaling also dictates opposing behaviors of a given effector.

The MotA and MotB proteins are thought to comprise elements of the stator component of the flagellar motor of Escherichia coli. In an effort to understand interactions among proteins within the motor, we attempted to identify extragenic suppressors of 31 dominant, plasmid-borne alleles of motA. Strains containing these mutations were either nonmotile or had severely impaired motility. Four of t...
Overlapping duplications recovered as suppressors of Minute loci have been used to localize M(2)z and M(3)w(124) to specific polytene bands 25A1(2) and 95A1(2). The surprising efficiency of M localization by duplication may result from the tendency of M suppressors to be at least a visible fraction of a polytene band in length.
