Comparative Analysis of RNase P

, 2003
This Master's Thesis contains a description of the results of two research projects that were worked on over the course of two years. The first was an attempt to heterologously reconstitute the Bacillus subtilis RNase P RNA with the RNase P protein ...

Sustainable Fabrication of Tailored Bone Substitutes: From High‐Throughput Scaffold Manufacturing, Scaled‐Up HMSC Expansion to Dynamic Cultivation in a Perfusion Bioreactor

Advanced Science, EarlyView.
ABSTRACT The demand for off‐the‐shelf biocompatible bone substitutes has driven the development of numerous independent in vitro technologies to generate products resembling physiological tissues. Due to technical challenges and overly simplified cultivation approaches/niches, the end‐products are often uniformly shaped and inferior to native bone ...

Molecular Editing Reveals a Bilobalide Chemotype that Attenuates Prolyl Endopeptidase (PREP)‐Linked Neuroinflammation

Advanced Science, EarlyView.
Molecular editing of bilobalide uncovers BB56, a PREP‐engaging chemotype with enhanced anti‐inflammatory activity in microglia. Integrated CETSA‐MS, SAR, and pathway analyses link BB56 to attenuation of p38 MAPK/NF‐κB and NLRP3‐associated inflammatory signaling, highlighting bilobalide editing as a strategy for developing neuroinflammation‐modulating ...

Bridge Nucleic Acid/DNA Gapmers as Potential Inhibitors of Bacterial Gene Expression by Multiple Antisense Mechanisms: An In Vitro Study

Molecules
Antisense inhibition of gene expression is usually achieved using nuclease-resistant oligonucleotide analogs that promote mRNA degradation through RNase H or RNase P, or by steric hindrance of translation.

Human RNase 7: a new cationic ribonuclease of the

, 2002
Here we report on the expression and function of RNase 7, one of the ®nal RNase A superfamily ribo-nucleases identi®ed in the human genome sequence. The human RNase 7 gene is expressed in various somatic tissues including the liver, kidney, skeletal ...

Early Retinal UCHL1 Dysregulation Coupled With Synaptic Loss Reflects Alzheimer's Disease Severity

Advanced Science, EarlyView.
This study identifies synapse‐enriched deubiquitinase UCHL1 as an early Aβ‐responsive regulator of retinal synaptopathy in Alzheimer's disease. Retinal UCHL1 loss accompanies excitatory synapse degeneration, p75NTR activation, and neuroinflammation, and predicts Braak stage and cognitive decline. Aβ42 fibrils trigger synaptic and UCHL1 depletion before

Binding and cleavage of unstructured RNA by nuclear RNase P

, 2011
Ribonuclease P (RNase P) is an essential endoribonuclease for which the best-characterized function is processing the 5′ leader of pre-tRNAs. Compared to bacterial RNase P, which contains a single small protein subunit and a large catalytic RNA subunit ...

Palatable‐Food–Driven Top‐Down Circuit Inhibits PVNCRF Activity to Mitigate Stress Via Peri‐PVNCRFR1 Neurons

Advanced Science, EarlyView.
Palatable food alleviates stress and prevents anxiety. This study uncovers a dedicated neural pathway: dopamine release in the PFC activates D1R neurons, whose projections to the peri‐PVN engage a population of anxiolytic CRFR1 neurons. These neurons then inhibit stress‐induced hyperactivity of PVNCRF neurons, providing a circuit‐level explanation for ...

Discovery and Engineering of a Rat Endogenous Retrovirus Reverse Transcriptase for Efficient Prime Editing

Advanced Science, EarlyView.
We screened 558 reverse transcriptases and engineered an optimized rat endogenous retrovirus‐derived variant, enRERV‐RT, via structure‐guided engineering and deep mutational scanning. This enhanced prime editor, based on the engineered RT, outperforms conventional M‐MLV‐RT systems across plant and animal cells, particularly at hard‐to‐edit loci ...

Partielle Aufreinigung der RNase P aus Kartoffelmitochondrien

, 1999
Die Aufreinigung der RNase P, des 5(Strich)-prozessierenden Enzyms der tRNA-Reifung, wurde ausgehend vom schon bestehenden Schema der partiellen Aufreinigung (Marchfelder und Brennicke 1994) fortgesetzt.
