Composition and conservation of the mRNA-degrading machinery in bacteria

Journal of Biomedical Science, 2011
RNA synthesis and decay counteract each other and therefore inversely regulate gene expression in pro- and eukaryotic cells by controlling the steady-state level of individual transcripts.

Transient Cytoskeletal Anisotropy Encodes Short‐Term Mechanical Memory in Glioblastoma Cells

Advanced Materials, EarlyView.
The same mechanical deformation can produce distinct cytoskeletal states depending on loading history. Experiments and constitutive modeling reveal that transient actin–vimentin anisotropy stores mechanical information and governs short‐term mechanical memory in glioblastoma cells.

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]

, 2012
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

Enzymes of physiological amyloidogenesis control pathological amyloid toxicity

Life Science Alliance
This study finds that modulating RNA tailing and decay enzymes can regulate proteotoxicity in Alzheimer’s and Parkinson’s disease models. Physiological amyloidogenesis drives the formation of functional amyloids involved in various biochemical pathways ...

Nonsense-Mediated RNA Decay Influences Human Embryonic Stem Cell Fate

Stem Cell Reports, 2016
Summary: Nonsense-mediated RNA decay (NMD) is a highly conserved pathway that selectively degrades specific subsets of RNA transcripts. Here, we provide evidence that NMD regulates early human developmental cell fate. We found that NMD factors tend to be

Bottom‐Up Engineering of a Human Neuromuscular System for Modeling Activity‐Induced Remodeling, Metabolic Stress, and Endothelial‐Modulated Excitability

Advanced Materials, EarlyView.
Using a bottom‐up approach, we engineered a human neuromuscular microchip to investigate distinct adaptive responses to neural stimulation and metabolic stress. Further integration of endothelial cells revealed their critical role in modulating neuromuscular excitability, establishing a comprehensive neurovascular‐muscular model.

Quantification of pre-mRNA escape rate and synergy in splicing [PDF]

, 2014
Splicing reactions generally combine high speed with accuracy. However, some of the pre-mRNAs escape the nucleus with a retained intron. Intron retention can control gene expression and increase proteome diversity.

Changes in mRNA abundance drive shuttling of RNA binding proteins, linking cytoplasmic RNA degradation to transcription

eLife, 2018
Alterations in global mRNA decay broadly impact multiple stages of gene expression, although signals that connect these processes are incompletely defined.

Lab‐in‐a‐Tube System Integrating Hierarchically Wrinkled Electrodes and DNAzyme‐Functionalized Beads for Diagnosis of Clostridioides difficile Infection

Advanced Materials, EarlyView.
The point‐of‐care diagnosis of Clostridioides difficile infection remains challenging due to reliance on slow culture and amplification‐based methods. A lab‐in‐a‐tube electrochemical biosensor integrating DNAzymes, antifouling magnetic beads, and a hierarchically structured flow cell enables amplification‐ and culture‐free detection directly in stool ...

Hydro‐ and Lipophilicity of Molecular‐Size‐Controlled Hydrogel Drug Carriers

Advanced Materials Technologies, EarlyView.
We investigate nano‐sized hydrogel drug carriers with tailored hydro‐ and lipophilicity. We design their encapsulation and structure‐forming capabilities and follow them in real time during fabrication using time‐resolved and in situ grazing incidence x‐ray scattering.
