The type II poly(A)-binding protein PABP-2 is a downstream target of the "let-7" microRNA in the heterochronic pathway of "Caenorhabditis elegans" : mechanisms of microRNA-mediated gene silencing in "Caenorhabditis elegans" [PDF]
microRNAs (miRNAs) are a large class of small, non-coding RNAs that post-transcriptionally regulate gene expression in animals, plants and protozoa. miRNAs are genomically encoded and transcribed by RNA polymerase II. Primary transcripts are sequentially

This study reveals that the small GTPase Rab14 is necessary for human papillomavirus (HPV) infection and plays an essential role in the transport of virions to the trans‐Golgi network (TGN). HPV in the early endosome (EE), which harbors GTP‐bound Rab14, is transported to the TGN through the switch of Rab14 from its GTP‐bound to GDP‐bound form.

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome
This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified

Definition of the minimal viral components required for the initiation of unprimed RNA synthesis by influenza virus RNA polymerase [PDF]
The first 11 nt at the 5' end of influenza virus genomic RNA were shown to be both necessary and sufficient for specific binding by the influenza virus polymerase.

Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells

Preliminary study on the mechanism of RNA-binding protein as a drug target of clofoctol [PDF]
Objective To explore the molecular mechanism of anti-glioma by clofoctol targeting on RNA-binding proteins. Methods Biotin pull-down experiments were used to detect the binding of RNA-binding protein UNR (upstream of N-ras) to the target gene Krüppel ...
