Segmentally Variable Genes: A New Perspective on Adaptation [PDF]
, 2004 Genomic sequence variation is the hallmark of life and is key to understanding diversity and adaptation among the numerous microorganisms on earth. Analysis of the sequenced microbial genomes suggests that genes are evolving at many different rates.

Advanced Science, EarlyView.We present a novel DNA vaccine platform featuring intrinsic, non‐targeting dsRNA that significantly enhances immune responses by activating the regulated IRE1‐dependent decay‐RIG‐I signaling pathway. This research elucidates a previously uncharacterized mechanism for dsRNA‐mediated innate immune activation.

Arenaviridae exoribonuclease presents genomic RNA edition capacity [PDF]
, 2019 AbstractThe Arenaviridae is a large family of viruses causing both acute and persistent infections and causing significant public health concerns in afflicted regions. A “trademark” of infection is the quick and efficient immuno-suppression mediated in part by a 3’-5’ RNA exonuclease domain (ExoN) of the Nucleoprotein (NP).

Direct observation of processive exoribonuclease motion using optical tweezers [PDF]
Proceedings of the National Academy of Sciences, 2015 Significance Bacteria regulate the synthesis and degradation of RNA molecules to ensure timely and robust responses to an ever-changing environment. The transcript’s lifetime can be influenced profoundly by a secondary structure that can form in the RNA and that may inhibit or promote its digestion by RNases.

Promotion of Bamboo mosaic virus accumulation in Nicotiana benthamiana by 5’→3’ exonuclease NbXRN4
Frontiers in Microbiology, 2016 Bamboo mosaic virus (BaMV) has a 6.4-kb (+) sense RNA genome with a 5’ cap and a 3’ poly(A) tail. ORF1 of this potexvirus encodes a 155-kDa replication protein responsible for the viral RNA replication/transcription and 5’ cap formation.

RNA‐Based Therapies for Inherited Metabolic Disorders
Journal of Inherited Metabolic Disease, Volume 49, Issue 2, March 2026.ABSTRACT Inherited metabolic disorders (IMDs) are a diverse and complex group of genetic conditions resulting from deficiencies in enzymes, transporters, or cofactors. These deficiencies lead to metabolic dysfunction and severe clinical consequences. Despite significant progress in understanding their molecular basis, treatment options remain limited ...

A novel role for the 3′-5′ exoribonuclease Dis3L2 in controlling cell proliferation and tissue growth [PDF]
, 2016 In a complex organism, cell proliferation and apoptosis need to be precisely controlled in order for tissues to develop correctly. Excessive cell proliferation can lead to diseases such as cancer. We have shown that the exoribonuclease Dis3L2 is required

Human FASTK preferentially binds single‐stranded and G‐rich RNA
The FEBS Journal, Volume 293, Issue 3, Page 729-748, February 2026.Although FASTK is known to play a role in mRNA biology, the mechanism through which it recognizes RNA has yet to be unraveled. Here, we used purified human FASTK to characterize its RNA‐binding properties in vitro. We found that FASTK prefers ssRNA oligonucleotides containing guanines with the potential to form G‐quadruplexes and binds robustly to any ...
