Findings suggest ILF3 may function as a reader of telomeric R-loops to help maintain telomere homeostasis

Dysregulated R-loops can cause stalled replication forks and telomere instability. However, how R-loops are recognized and regulated, is still not well understood, particularly at telomeres.

Researchers reveal mechanism behind most common mammalian mRNA modification

RNA—in the form of messenger RNA (mRNA), ribosomal RNA (rRNA), and transfer RNA (tRNA)—transforms the genome coded by DNA into proteins that form the backbone of all cellular functions. However, biochemical modifications ...

Rogue enzymes cause numerous diseases, but a new method could help design drugs to treat them

Helicases are enzymes that unwind DNA and RNA. They're central to cellular life, implicated in a number of cancers and infections—and, alas, extraordinarily difficult to target with drugs.

How nearly identical RNA helicases drive 'mRNA export' via distinct protein complex pathways

Genetic expression, often leading to protein synthesis, requires a complex coordination of molecular machinery across several stages. A vital step in protein-coding gene expression is messenger RNA (mRNA) export, which involves ...

Studies describe genetic basis of long-term heat tolerance in model plant

Two papers published in PNAS Nexus describe the genetic basis of long-term heat tolerance in the model plant Arabidopsis thaliana, with implications for crop breeding. Teruaki Taji and colleagues evaluated dozens of lines ...

Downstream RNA hairpins found orchestrating mRNA translation

Research led by Duke University, Durham, has discovered a situation-dependent traffic jam in mRNA translation caused by RNA hairpins leading to higher translation of upstream start codons (uAUGs).

Biochemist unravels the secrets of a novel DNA enzyme linked to infertility and certain cancers

Scientific research requires patience. The rewards are not always immediate, and the technology needed does not always exist. Michael A. Trakselis, Ph.D., professor and director of graduate affairs for the Department of Chemistry ...

Researchers identify novel host-based target against multiple mosquito-transmitted viruses

New Cleveland Clinic research shows how mosquito-transmitted viruses—like Zika, West Nile, Yellow Fever and dengue viruses—hijack host cells to promote their own replication and infection. Published in Cell Host and Microbe, ...

How certain proteins contribute to the formation of a class of RNA critical to protecting the genome investigated

You're likely familiar with RNA, the molecule that plays an important role in protein production and gene expression control. Perhaps you're less familiar, however, with PIWI-interacting RNA (piRNA), a special type of RNA ...

Learning how to control HIV from African genomes

A study on almost four thousand people of African descent has identified a gene that acts as natural defense against HIV by limiting its replication in certain white blood cells. An international effort co-led by EPFL, Canada's ...
