RNA Methylation and Metabolism [PDF]

open access: yesScience, 2013
Molecular Biology The methylation—and demethylation—of DNA play an important role in the dynamic regulation of gene expression and in genome stability. RNA in eukaryotes is also methylated on the A base (m6A), the most abundant posttranscriptional modification of mammalian mRNA.

Analysis of tissue-specific & allele-specific DNA methylation [PDF]

open access: yes, 2010
Epigenetic mechanisms such as histone modifications and DNA methylation extend the information of the underlying genomic DNA sequence. Understanding cell type-specific epigenetic codes on a global level is a major challenge after the sequencing of the ...

Race and Household Income Are Associated With Disease Outcomes in Pediatric Patients With Antineutrophil Cytoplasmic Antibody–Associated Vasculitis Hospitalized in the United States

open access: yesArthritis Care &Research, EarlyView.
Objective Race and household income impact outcomes in patients with rheumatic conditions; however, their role in pediatric antineutrophil cytoplasmic antibody (ANCA)–associated vasculitis (AAV) remains poorly understood. We aimed to evaluate whether race and ethnicity and household income are associated with severe AAV disease and renal outcomes among

Maf1-mediated repression of RNA polymerase III transcription inhibits tRNA degradation via RTD pathway [PDF]

open access: yes, 2012
tRNA precursors, which are transcribed by RNA polymerase III, undergo end-maturation, splicing and base modifications. Hypomodified tRNAs, such as tRNAVal(AAC), lacking 7-methylguanosine and 5-methylcytidine modifications, are subject to degradation by a

Targeting CD300a Signaling With a Phosphatidylserine‐Presenting Hydrogel Rescues Macrophage Dysfunction and Accelerates Diabetic Wound Healing

open access: yesAdvanced Healthcare Materials, EarlyView.
Schematic illustration of the proposed mechanism: PEG/RGD‐PSLs mimic apoptotic cells to engage PS receptors (notably CD300a), transducing an inhibitory signal that suppresses the MyD88/NF‐κB pathway, leading to global anti‐inflammatory and pro‐reparative effects.

Advanced Materials for Biologics Delivery to Brain Tumors

open access: yesAdvanced Materials, EarlyView.
Material innovation is central to unlocking the therapeutic potential of biologics against many central nervous system diseases, including brain cancer. By engineering carriers with controlled transport, targeting, and release properties, advanced materials can overcome the blood–brain barrier and tumor microenvironment, improving the delivery of ...

Diverging affinity of tospovirus RNA silencing suppressor proteins, NSs, for various RNA duplex molecules [PDF]

open access: yes, 2010
The tospovirus NSs protein was previously shown to suppress the antiviral RNA silencing mechanism in plants. Here the biochemical analysis of NSs proteins from different tospoviruses, using purified NSs or NSs containing cell extracts, is described.

Microgels Enable iPSCs to Assemble, Expand, and Differentiate Into Organoids—From Sizable to High‐Throughput

open access: yesAdvanced Materials, EarlyView.
A chemically defined PEG‐based microgel platform enables scalable, reproducible production of three‐dimensional microgel‐iPSC constructs in multiple sizes. The system is compatible with high‐throughput automation and supports human iPSC expansion and differentiation within a single construct, including directed differentiation into cardiac organoids ...

RNA methylation in retrotransposon control

open access: yesTrends in Genetics
N6-methyladenosine (m6A) regulates retrotransposon activity, shifting between repression and activation across different species and developmental stages. It promotes RNA decay, sequestration, or stability, influencing genome integrity, adaptation, and disease.

RAM function is dependent on Kapβ2-mediated nuclear entry [PDF]

open access: yes, 2014
Eukaryotic gene expression is dependent on the modification of the first transcribed nucleotide of pre-mRNA by the addition of the 7-methylguanosine cap.
