RIN4 homologs from important crop species differentially regulate the Arabidopsis NB-LRR immune receptor, RPS2.

RIN4 homologs from important crop species differ in their ability to prevent ectopic activity of the nucleotide binding-leucine rich repeat resistance protein, RPS2. Pathogens deploy virulence effectors to perturb host processes. Plants utilize intracellular resistance (R) proteins to recognize pathogen effectors either by direct interaction or indirectly via effector-mediated perturbations of host components.

Protein mimetic amyloid inhibitor potently abrogates cancer-associated mutant p53 aggregation and restores tumor suppressor function.

Missense mutations in p53 are severely deleterious and occur in over 50% of all human cancers. The majority of these mutations are located in the inherently unstable DNA-binding domain (DBD), many of which destabilize the domain further and expose its aggregation-prone hydrophobic core, prompting self-assembly of mutant p53 into inactive cytosolic amyloid-like aggregates. Screening an oligopyridylamide library, previously shown to inhibit amyloid formation associated with Alzheimer's disease and type II diabetes, identified a tripyridylamide, ADH-6, that abrogates self-assembly of the aggregation-nucleating subdomain of mutant p53 DBD.

Classification and experimental identification of plant long non-coding RNAs.

Our understanding of gene regulation is constantly evolving. It is now clear that the majority of cellular transcripts are non-coding RNAs. The spectrum of non-coding RNAs is diverse and includes short (<200 nt) and long non-coding RNAs (lncRNAs) (>200 nt).
