Lipopolysaccharide uptake is augmented in lipopolysaccharide‐tolerant mouse macrophage‐like cells via increased CD14 expression

FEBS Open Bio, EarlyView.
In normal (nontolerant) cells, CD14 is crucial for both LPS uptake and LPS signaling. In LPS‐tolerant cells, in which LPS‐induced TNF‐α and IFN‐β production is suppressed, there is a dramatic increase in surface CD14 expression. The overexpressed CD14 in LPS‐tolerant cells is responsible for the enhanced LPS uptake without inducing pro‐inflammatory ...

Cyclic azapeptide CD36 ligand attenuates cardiac injury and reduces long‐chain fatty acid accumulation after myocardial ischemia–reperfusion in mice

FEBS Open Bio, EarlyView.
In a murine model of myocardial ischemia and reperfusion (MI/R), the CD36 azapeptide ligand MPE‐298 reduces cardiac injury and transiently lowers left ventricular long‐chain fatty acids (LCFAs) accumulation 3 h after reperfusion, accompanied by a decrease of oxidative stress and inflammation‐associated genes' expression in the heart and adipose tissue.

Aquaporin‐3 and aquaporin‐5 impact the development of pancreatic ductal adenocarcinoma spheroids

FEBS Open Bio, EarlyView.
Schematic representation of the role of aquaporin‐3 (AQP3) and aquaporin‐5 (AQP5) in pancreatic ductal adenocarcinoma (PDAC). Both proteins are upregulated in PDAC and are associated with tumor progression and metastatic potential. Silencing AQP3 or AQP5 in PDAC spheroids results in decreased diameter, area, and overall growth, underscoring their key ...

Directed evolution of enzymes at the crossroads of tradition and innovation

FEBS Open Bio, EarlyView.
An iterative cycle of data‐driven enzyme optimization comprising four stages: genetic diversification of a template enzyme, expression of protein variants, high‐throughput evaluation, and machine‐learning‐guided redesign of the next variant library.

Small RNA pathways in mammalian oocytes

FEBS Open Bio, EarlyView.
Three distinct small RNA pathways operate in mammalian oocytes: RNAi interference (RNAi), the microRNA (miRNA) pathway, and the PIWI‐associated RNA (piRNA) pathway. These pathways use small RNAs to guide sequence‐specific repression and contribute to oocyte biology by targeting genes and mobile elements or appear insignificant since different ...

Architecture of RNA–RNA interactions

Current Opinion in Genetics & Development, 2022
RNA molecules tend to form intricate tertiary structures via intramolecular RNA-RNA interactions (RRIs) to regulate transcription, RNA processing, and translation processes. In these biological processes, RNAs, especially noncoding RNAs, usually achieve their regulatory specificity through intermolecular RNA-RNA base pairing and execute their ...

RNA Editing with Viral RNA-Dependent RNA Polymerase

ACS Synthetic Biology, 2022
RNA editing is currently attracting attention as a method for editing genetic information without injury to the genome. The most common approach to edit RNA sequences involves the induction of an A-to-I change by adenosine deaminase acting on RNA (ADAR). However, this method only allows point editing.

RNA-dependent RNA polymerases in RNA silencing

Biological Chemistry, 2011
Abstract RNA-dependent RNA polymerases (RdRPs) synthesize double-stranded RNAs that are processed into small RNAs and mediate gene silencing. Viral RdRPs and cellular RdRPs show little structural homology to each other. Cellular RdRPs play key roles in RNA silencing by producing complementary strands for target RNAs via Dicer-dependent and -

RNA Libraries and RNA Recognitiona

Annals of the New York Academy of Sciences, 1996
Random RNA libraries, consisting of > 10(13) unique sequences, contain molecules capable of specifically binding small molecule and protein ligands by noncovalent interaction. Successive steps of affinity purification and amplification allow the propagation and eventual isolation of specific binding molecules, called aptamers.
